In an adult patient with Marfan syndrome, what is the most frequently observed cardiovascular abnormality?
Your Answer: Aortic root dilatation
Explanation:Marfan Syndrome: A Connective Tissue Disorder with Cardiovascular Manifestations
Marfan syndrome is an autosomal dominant connective tissue disorder that presents with a wide range of clinical manifestations. The ocular, skeletal, and cardiovascular systems are characteristically involved. Aortic root dilatation, occurring in 70-80% of cases, is the most common cardiovascular manifestation, followed by mitral valve prolapse at 60-70%. Mitral annular calcification is less common, occurring in 8-15% of cases. Aortic dissection, accounting for around 5% of all cases, is more likely in patients with Marfan syndrome, especially those with severe aortic root dilatation.
The weakening of the aortic media leads to a fusiform ascending aortic aneurysm, which may be complicated by aortic regurgitation and aortic dissection. Mitral regurgitation can result from mitral valve prolapse, dilatation of a mitral valve annulus, or mitral annular calcification. Pregnancy is particularly hazardous for patients with Marfan syndrome. Treatment with β blockers can reduce the rate of aortic dilatation and the risk of rupture.

A child is born by an emergency Caesarean section at 38 weeks, due to pathological cardiotocography. The child appears healthy at birth, with Apgar scores of 9 and 10 (1 and 5 minutes respectively). Shortly after delivery, the nurse observes that the child's respiratory rate is elevated (all other observations are normal). The mother's antenatal history is unremarkable and her observations were normal during labor. What is the probable diagnosis?
Your Answer: Transient tachypnoea of the newborn (TTN)
Explanation:Understanding Transient Tachypnoea of the Newborn
Transient tachypnoea of the newborn (TTN) is a common respiratory condition that affects newborns. It is caused by the delayed resorption of fluid in the lungs, which can lead to breathing difficulties. TTN is more common in babies born via caesarean section, as the fluid in their lungs may not be squeezed out during the birth process. A chest x-ray may show hyperinflation of the lungs and fluid in the horizontal fissure.
The management of TTN involves observation and supportive care. In some cases, supplementary oxygen may be required to maintain oxygen saturation levels. However, TTN usually resolves within 1-2 days. It is important for healthcare professionals to monitor newborns with TTN closely and provide appropriate care to ensure a full recovery. By understanding TTN and its management, healthcare professionals can provide the best possible care for newborns with this condition.

A 28-year-old woman visits her family doctor with a lump under her chin that causes her discomfort and swelling, especially after eating a big meal. The facial nerve appears to be unaffected. Upon examination, there is a tender swelling in the submandibular triangle. What is the probable diagnosis?
Your Answer: Warthin’s tumour
Correct Answer: Sialolithiasis
Explanation:Differential Diagnosis for a Painful Submandibular Swelling
One possible diagnosis for a painful submandibular swelling is sialolithiasis, which is the formation of stones within the salivary glands. This condition is more common in men over 40 and typically causes pain and swelling after eating. Adenoid cystic carcinoma, on the other hand, presents as a slowly enlarging mass over the parotid area and can invade local structures such as the facial nerve. Pleomorphic adenomas usually present as a painless lump that slowly enlarges, while Sjögren syndrome causes dry mouth, dry eyes, and swelling of the salivary glands bilaterally. Warthin’s tumour, which is commonly found in the tail of the parotid gland, does not typically present as a painful lump.

An 80-year-old man with a known history of mixed type dementia (Alzheimer's and vascular) is evaluated in memory clinic due to a recent decline in his memory and cognition. His mini-mental state score is 12 and he is started on memantine. What is the mechanism of action of memantine?
Your Answer: NMDA antagonist
Explanation:Memantine is an NMDA receptor antagonist and is not a cholinesterase inhibitor like donepezil and rivastigmine. While memantine does act at the serotonin and dopamine receptors, it acts as an antagonist and agonist respectively, rather than the options given.
Managing Alzheimer’s Disease: Non-Pharmacological and Pharmacological Approaches
Alzheimer’s disease is a type of dementia that progressively affects the brain and is the most common form of dementia in the UK. To manage this condition, there are both non-pharmacological and pharmacological approaches available.
Non-pharmacological management involves offering a range of activities that promote wellbeing and are tailored to the patient’s preferences. Group cognitive stimulation therapy is recommended for patients with mild to moderate dementia, while group reminiscence therapy and cognitive rehabilitation are also options to consider.
Pharmacological management involves the use of medications. The three acetylcholinesterase inhibitors (donepezil, galantamine, and rivastigmine) are options for managing mild to moderate Alzheimer’s disease. Memantine, an NMDA receptor antagonist, is considered a second-line treatment and is recommended for patients with moderate Alzheimer’s who are intolerant of or have a contraindication to acetylcholinesterase inhibitors. It can also be used as an add-on drug to acetylcholinesterase inhibitors for patients with moderate or severe Alzheimer’s or as monotherapy in severe Alzheimer’s.
When managing non-cognitive symptoms, NICE does not recommend antidepressants for mild to moderate depression in patients with dementia. Antipsychotics should only be used for patients at risk of harming themselves or others or when the agitation, hallucinations, or delusions are causing them severe distress.
It is important to note that donepezil is relatively contraindicated in patients with bradycardia, and adverse effects may include insomnia. By utilizing both non-pharmacological and pharmacological approaches, patients with Alzheimer’s disease can receive comprehensive care and management.

A middle-aged man with a history of chronic alcohol abuse presents to the Emergency Department. He appears disheveled, lethargic, and disoriented, and it is suspected that he has not had a meal in the past two days. The medical team decides to initiate chlordiazepoxide PRN and administer IV Pabrinex. Which specific vitamin, found in Pabrinex, can help halt the progression of symptoms leading to Wernicke's encephalopathy?
Your Answer: C
Correct Answer: B1
Explanation:Understanding Wernicke’s Encephalopathy
Wernicke’s encephalopathy is a condition that affects the brain and is caused by a deficiency in thiamine. This condition is commonly seen in individuals who abuse alcohol, but it can also be caused by persistent vomiting, stomach cancer, or dietary deficiencies. The classic triad of symptoms associated with Wernicke’s encephalopathy includes oculomotor dysfunction, gait ataxia, and encephalopathy. Other symptoms may include peripheral sensory neuropathy and confusion.
When left untreated, Wernicke’s encephalopathy can lead to the development of Korsakoff’s syndrome. This condition is characterized by antero- and retrograde amnesia and confabulation in addition to the symptoms associated with Wernicke’s encephalopathy.
To diagnose Wernicke’s encephalopathy, doctors may perform a variety of tests, including a decreased red cell transketolase test and an MRI. Treatment for this condition involves urgent replacement of thiamine. With prompt treatment, individuals with Wernicke’s encephalopathy can recover fully.

A 45-year-old man visits his GP with a 7-month history of abdominal bloating, pain and urgency to defecate in the morning. He has no history of nausea/vomiting, per rectum bleeding, mucus on stools or weight loss. He says that his symptoms become much worse, with worsening constipation, when he is stressed. Physical examination is unremarkable.
Which of the following is the best initial treatment for his symptoms?
Your Answer: Mebeverine
Explanation:Understanding and Managing Irritable Bowel Syndrome (IBS)
Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder that affects 10-20% of the population, with women being more likely to develop it than men. It is characterized by abdominal pain, bloating, and altered bowel habits without any specific organic pathology.
Diagnosis of IBS is based on the presence of symptoms such as abdominal pain or discomfort, bloating, and change in bowel habit for at least 6 months. Physical examination and further investigations are necessary to exclude other differential diagnoses.
Management of IBS primarily involves psychological support and dietary measures such as fiber supplementation, low FODMAP diets, increased water intake, and avoiding trigger foods. Pharmacological treatment is adjunctive and should be directed at symptoms. Anti-spasmodics, anti-diarrheals, and antidepressants may have a positive effect on symptoms.
It is important to note that symptoms not consistent with IBS, such as rectal bleeding, anorexia/weight loss, nocturnal symptoms, or fecal incontinence, should alert the clinician to the possibility of an organic pathology. Referral for psychological therapies should be considered for patients who do not respond to pharmacological treatments after 12 months and who develop a continuing symptom profile.

A 28 year-old carpenter complains of itchy and painful skin on his hands and wrists. He suspects that it might be due to something he is exposed to at work. What test would be most appropriate to investigate this hypothesis?
Your Answer: Patch testing
Explanation:When there is a suspicion of allergic contact dermatitis, patch testing is the preferred method of investigation. This condition can be caused by either irritants or allergens. The patient’s back is exposed to different allergens, including standard batteries and any substances that the patient suspects. The skin is then evaluated for any reaction after 48 hours and 7 days.
Understanding Contact Dermatitis
Contact dermatitis is a skin condition that can be caused by two main types of reactions. The first type is irritant contact dermatitis, which is a non-allergic reaction that occurs due to exposure to weak acids or alkalis, such as detergents. This type of dermatitis is commonly seen on the hands and is characterized by erythema, but crusting and vesicles are rare. The second type is allergic contact dermatitis, which is a type IV hypersensitivity reaction. This type of dermatitis is uncommon and is often seen on the head following hair dyes. It presents as an acute weeping eczema that predominantly affects the margins of the hairline rather than the hairy scalp itself. Topical treatment with a potent steroid is indicated for this type of dermatitis.
Cement is a frequent cause of contact dermatitis. The alkaline nature of cement may cause an irritant contact dermatitis, while the dichromates in cement can also cause an allergic contact dermatitis. It is important to understand the different types of contact dermatitis and their causes to properly diagnose and treat the condition. Proper treatment can help alleviate symptoms and prevent further complications.

A 55-year-old woman visits her GP seeking advice on starting hormone replacement therapy (HRT) due to distressing vasomotor symptoms. Her LMP was 10 months ago, and she has not undergone any surgeries, has no significant medical history, and is not sexually active. Despite making lifestyle changes, she has not experienced much relief. Assuming there are no contraindications, what treatment would you suggest?
Your Answer: Continuous combined HRT
Correct Answer: Cyclical combined HRT
Explanation:When a woman expresses interest in starting hormone replacement therapy (HRT), it is important to gather a detailed medical history to determine her menopausal status. This includes information about her last menstrual period (LMP) and any bleeding patterns leading up to it. Based on this information, it appears that the woman in question is peri-menopausal, as she has not been without a period for a full year.
The primary reason for starting HRT is to alleviate vasomotor symptoms, such as hot flashes. However, it may also be used to prevent osteoporosis in women who have been diagnosed with premature menopause.
For women who still have a uterus, HRT should consist of a combination of estrogen and progesterone. The progesterone is essential for reducing the risk of endometrial cancer, which can occur when estrogen is used alone. Women who have had a hysterectomy will typically receive continuous estrogen-only therapy.
The type of HRT prescribed will depend on the woman’s menopausal status. Those who have had their LMP within the past year should receive cyclical combined HRT, while those who have been without a period for at least a year or who have experienced premature menopause should receive continuous combined HRT.
For women who are unable or unwilling to take HRT, there are several non-hormonal treatments available for vasomotor symptoms. These include certain selective serotonin and noradrenaline reuptake inhibitors, clonidine, and gabapentin. However, sertraline is not effective for treating hot flashes. It is worth noting that the National Institute for Health and Clinical Excellence (NICE) does not recommend the use of herbal or complementary therapies for managing hot flashes and night sweats.
Hormone replacement therapy (HRT) involves a small dose of oestrogen and progestogen to alleviate menopausal symptoms. The indications for HRT have changed due to the long-term risks, and it is primarily used for vasomotor symptoms and preventing osteoporosis in younger women. HRT consists of natural oestrogens and synthetic progestogens, and can be taken orally or transdermally. Transdermal is preferred for women at risk of venous thromboembolism.

A 35-year-old woman is concerned about her risk of developing ovarian cancer due to a family history of the disease. She wants to learn more about screening options available in the UK.
Which of the following statements is correct?Your Answer: Screening is only offered to women who have a family history of ovarian cancer
Correct Answer: There is currently no screening programme for ovarian cancer
Explanation:Currently, there is no dependable screening test for detecting ovarian cancer in its early stages. However, women, especially those over 50 years old, who experience persistent symptoms such as abdominal bloating, early satiety, loss of appetite, pelvic or abdominal pain, and increased urinary urgency or frequency should be suspected of having ovarian cancer and should undergo further tests.
Ovarian cancer is a common malignancy in women, ranking fifth in frequency. It is most commonly diagnosed in women over the age of 60 and has a poor prognosis due to late detection. The majority of ovarian cancers, around 90%, are of epithelial origin, with serous carcinomas accounting for 70-80% of cases. Interestingly, recent research suggests that many ovarian cancers may actually originate in the distal end of the fallopian tube. Risk factors for ovarian cancer include a family history of BRCA1 or BRCA2 gene mutations, early menarche, late menopause, and nulliparity.
Clinical features of ovarian cancer are often vague and can include abdominal distension and bloating, abdominal and pelvic pain, urinary symptoms such as urgency, early satiety, and diarrhea. The initial diagnostic test recommended by NICE is a CA125 blood test, although this can also be elevated in other conditions such as endometriosis and benign ovarian cysts. If the CA125 level is raised, an urgent ultrasound scan of the abdomen and pelvis should be ordered. However, a CA125 test should not be used for screening asymptomatic women. Diagnosis of ovarian cancer is difficult and usually requires a diagnostic laparotomy.
Management of ovarian cancer typically involves a combination of surgery and platinum-based chemotherapy. Unfortunately, 80% of women have advanced disease at the time of diagnosis, leading to a 5-year survival rate of only 46%. It was previously thought that infertility treatment increased the risk of ovarian cancer due to increased ovulation, but recent evidence suggests that this is not a significant factor. In fact, the combined oral contraceptive pill and multiple pregnancies have been shown to reduce the risk of ovarian cancer by reducing the number of ovulations.

A 65-year-old woman presents to her GP with whole-body itching which is worse after she has taken a bath, tingling and burning sensations in her hands and feet, and headaches. She has felt fatigued over the past year and a half, however, the symptoms of itching and tingling peripheries have only been present for the past 3 months. On examination, she is noted to have a palpable spleen which is 3 cm below the costal angle. She has a full blood count which shows:
Hb 184 g/L Female: (115 - 160)
Platelets 380 * 109/L (150 - 400)
WBC 9.0 * 109/L (4.0 - 11.0)
What is the recommended first-line treatment for this patient?Your Answer: Phlebotomy
Explanation:The primary treatment for polycythaemia vera is venesection, which is used to maintain normal levels of haemoglobin. This patient is displaying symptoms consistent with the condition, including pruritis, numbness and tingling in the extremities, headaches, lethargy, and splenomegaly. Venesection involves removing blood from the patient to reduce haemoglobin levels, and may need to be performed weekly initially, but can be spaced out to every 6-12 weeks once the condition is under control. Ibuprofen is not a recommended treatment for polycythaemia vera, but aspirin can be used to reduce the risk of clotting. Paroxetine has been studied as a treatment for pruritis associated with polycythaemia vera, but should not be used as a replacement for venesection. Ruxolitinib is a medication used to prevent thrombus formation in patients who are resistant or intolerant to hydroxyurea, but is not a first-line treatment for the condition.
Polycythaemia vera is a condition where a single marrow stem cell undergoes clonal proliferation, leading to an increase in red cell volume, as well as an overproduction of neutrophils and platelets. This disorder is most commonly seen in individuals in their sixth decade of life and is characterized by symptoms such as hyperviscosity, pruritus, and splenomegaly.
The management of polycythaemia vera involves several approaches. Aspirin is often prescribed to reduce the risk of thrombotic events. Venesection is the first-line treatment to keep the haemoglobin levels within the normal range. Chemotherapy, such as hydroxyurea, may also be used, but it carries a slight increased risk of secondary leukaemia. Phosphorus-32 therapy is another option.
The prognosis for polycythaemia vera is variable. Thrombotic events are a significant cause of morbidity and mortality. Additionally, 5-15% of patients may progress to myelofibrosis, while another 5-15% may develop acute leukaemia, with the risk being increased with chemotherapy treatment.

A 45-year-old woman complains of a gritty sensation in her eyes and a dry mouth of several months’ duration. She has vague joint pains in her knees and ankles. Her husband mentions that she is also dyspnoeic on exertion and cannot keep up with him during their hikes.
Which of the following is the most likely diagnosis?Your Answer: Sjögren syndrome
Explanation:Sjögren syndrome is a condition characterized by dry eyes (keratoconjunctivitis sicca) and dryness in other areas such as the mouth, skin, or vagina. Enlargement of the salivary or parotid glands may also be present. Primary Sjögren syndrome occurs without any other autoimmune disease and is associated with HLA-B8/DR3 in about 50% of cases. Secondary Sjögren syndrome occurs in the presence of other autoimmune disorders, commonly rheumatoid arthritis (RA). Other symptoms may include arthralgia, Raynaud’s phenomenon, oesophageal dysmotility, vasculitis, polyneuropathy, and pulmonary diffusion defects and fibrosis. Diagnosis is based on the Schirmer tear test, Rose Bengal staining, and lab tests showing raised immunoglobulin levels, circulating immune complexes, and autoantibodies. Treatment is symptomatic with artificial tear and saliva replacement solutions, hydroxychloroquine, and corticosteroids if needed. Polymyositis, polyarteritis nodosa (PAN), mixed connective tissue disease (MCTD), and rheumatoid arthritis are other conditions that may present with similar symptoms but do not fit the clinical picture in this case.

A 63-year-old man visits your clinic for his regular asthma inhaler prescription. During the consultation, he mentions experiencing difficulty in sustaining his erections and requests a prescription for sildenafil. What is the most prevalent side effect of sildenafil?
Your Answer: Headaches
Explanation:Sildenafil is frequently prescribed in primary care. Adverse effects of sildenafil consist of headaches, facial flushing, indigestion, and temporary visual disturbances with a blue-green tint.
Understanding Phosphodiesterase Type V Inhibitors
Phosphodiesterase type V (PDE5) inhibitors are medications used to treat erectile dysfunction and pulmonary hypertension. These drugs work by increasing the levels of cGMP, which leads to the relaxation of smooth muscles in the blood vessels supplying the corpus cavernosum. The most well-known PDE5 inhibitor is sildenafil, also known as Viagra, which was the first drug of its kind. It is a short-acting medication that is usually taken one hour before sexual activity.
Other PDE5 inhibitors include tadalafil (Cialis) and vardenafil (Levitra). Tadalafil is longer-acting than sildenafil and can be taken on a regular basis, while vardenafil has a similar duration of action to sildenafil. However, these drugs are not suitable for everyone. Patients taking nitrates or related drugs, those with hypotension, and those who have had a recent stroke or myocardial infarction should not take PDE5 inhibitors.
Like all medications, PDE5 inhibitors can cause side effects. These may include visual disturbances, blue discolouration, non-arteritic anterior ischaemic neuropathy, nasal congestion, flushing, gastrointestinal side-effects, headache, and priapism. It is important to speak to a healthcare professional before taking any medication to ensure that it is safe and appropriate for you.
Overall, PDE5 inhibitors are an effective treatment for erectile dysfunction and pulmonary hypertension. However, they should only be used under the guidance of a healthcare professional and with careful consideration of the potential risks and benefits.

A 28-year-old female patient presents to her GP complaining of a foul-smelling vaginal discharge that has persisted for 5 days after having unprotected sex. She reports feeling generally well and denies any fever or urinary symptoms. The patient also confirms that she is not pregnant. During the examination, the doctor observes multiple punctate lesions on her cervix and a green discharge with a strong odor. What is the probable diagnosis?
Your Answer: Gonorrhoea
Correct Answer: Trichomoniasis
Explanation:The patient is likely suffering from trichomoniasis caused by Trichomonas vaginalis, a sexually transmitted disease that results in a yellow/green discharge with a foul odor, vulval itching, and dysuria. During a speculum examination, the cervix may appear as a strawberry cervix due to multiple punctate haemorrhages. Bacterial vaginosis, which is not a sexually transmitted disease and can be caused by various factors, is less likely to be the diagnosis due to the recent unprotected sexual intercourse and the presence of an offensive discharge. Chlamydia and gonorrhoea, both sexually transmitted diseases, can also cause dysuria and vaginal discharge, but the punctate cervical haemorrhages and malodorous green discharge make them less likely diagnoses. Syphilis, which presents in three stages, is unlikely due to the acute onset of symptoms and the absence of genital lesions.
Understanding Trichomonas vaginalis and its Comparison to Bacterial Vaginosis
Trichomonas vaginalis is a type of protozoan parasite that is highly motile and flagellated. It is known to cause trichomoniasis, which is a sexually transmitted infection. The infection is characterized by symptoms such as offensive, yellow/green, frothy vaginal discharge, vulvovaginitis, and strawberry cervix. The pH level is usually above 4.5, and in men, it may cause urethritis.
To diagnose trichomoniasis, a wet mount microscopy is conducted to observe the motile trophozoites. The treatment for trichomoniasis involves oral metronidazole for 5-7 days, although a one-off dose of 2g metronidazole may also be used.
When compared to bacterial vaginosis, trichomoniasis has distinct differences. Bacterial vaginosis is caused by an overgrowth of bacteria in the vagina, while trichomoniasis is caused by a protozoan parasite. The symptoms of bacterial vaginosis include a thin, grayish-white vaginal discharge with a fishy odor, and a pH level above 4.5. Unlike trichomoniasis, bacterial vaginosis is not considered a sexually transmitted infection.
In conclusion, understanding the differences between trichomoniasis and bacterial vaginosis is crucial in diagnosing and treating these conditions effectively. Proper diagnosis and treatment can help prevent complications and improve overall health and well-being.

A 68-year-old man presents to clinic with increasing breathlessness, weight loss and peripheral oedema over the past 2 months. His family are concerned that he has also become a bit more confused over the past week.
His past history includes hypertension and a 35 pack-year smoking history. An echocardiogram from last year showed good biventricular contraction.
His blood tests show the following:
Haemoglobin (Hb) 150 g/L
Platelets 230 * 109/L (150 - 400)
White cell count (WCC) 4.6 * 109/L (4.0 - 11.0)
Na+ 124 mmol/L (135 - 145)
K+ 3.5 mmol/L (3.5 - 5.0)
Urea 2.0 mmol/L (2.0 - 7.0)
Creatinine 62 µmol/L (55 - 120)
C reactive protein (CRP) 6 mg/L (< 5)
What is the most likely diagnosis?Your Answer: Right-sided heart failure
Correct Answer: Lung cancer
Explanation:Investigation for lung cancer should be considered in a long-term smoker with a history of weight loss and breathlessness, as SIADH is a common endocrine complication of small cell lung cancer. If the patient has not had a normal echo recently, right-sided heart failure may be a more likely explanation for their symptoms. While COPD and pulmonary fibrosis can also cause breathlessness, they would not account for the peripheral oedema and hyponatraemia.
SIADH is a condition where the body retains too much water, leading to low sodium levels in the blood. This can be caused by a variety of factors, including malignancies such as small cell lung cancer, neurological conditions like stroke or meningitis, infections such as tuberculosis or pneumonia, and certain drugs like sulfonylureas and SSRIs. Other causes may include positive end-expiratory pressure and porphyrias. Treatment for SIADH involves slowly correcting the sodium levels to avoid complications like central pontine myelinolysis. This can be done through fluid restriction, the use of demeclocycline to reduce responsiveness to ADH, or the use of ADH receptor antagonists. It is important to note that certain drugs, such as glimepiride and glipizide, have been reported to cause SIADH according to the BNF.

A 35-year-old female patient attends a routine appointment at the GP surgery to discuss her use of the combined oral contraceptive pill (COCP). She informs you that she has recently started taking some medications and is concerned about their potential impact on the effectiveness of the contraceptive pill. Can you identify which medication may decrease the efficacy of the COCP?
Your Answer: Fluconazole
Correct Answer: St John's wort
Explanation:If enzyme-inducing drugs are taken at the same time as the combined oral contraceptive pill, its effectiveness is decreased. Out of the given choices, only St John’s wort is an enzyme inducer, while the rest are enzyme inhibitors.
Counselling for Women Considering the Combined Oral Contraceptive Pill
Women who are considering taking the combined oral contraceptive pill (COC) should receive counselling on the potential harms and benefits of the pill. The COC is highly effective if taken correctly, with a success rate of over 99%. However, there is a small risk of blood clots, heart attacks, and strokes, as well as an increased risk of breast and cervical cancer.
In addition to discussing the potential risks and benefits, women should also receive advice on how to take the pill. If the COC is started within the first 5 days of the menstrual cycle, there is no need for additional contraception. However, if it is started at any other point in the cycle, alternative contraception should be used for the first 7 days. Women should take the pill at the same time every day and should be aware that intercourse during the pill-free period is only safe if the next pack is started on time.
There have been recent changes to the guidelines for taking the COC. While it was previously recommended to take the pill for 21 days and then stop for 7 days to mimic menstruation, it is now recommended to discuss tailored regimes with women. This is because there is no medical benefit to having a withdrawal bleed, and options include never having a pill-free interval or taking three 21-day packs back-to-back before having a 4 or 7 day break.
Women should also be informed of situations where the efficacy of the pill may be reduced, such as vomiting within 2 hours of taking the pill, medication that induces diarrhoea or vomiting, or taking liver enzyme-inducing drugs. It is also important to discuss sexually transmitted infections and precautions that should be taken with enzyme-inducing antibiotics such as rifampicin.
Overall, counselling for women considering the COC should cover a range of topics to ensure that they are fully informed and able to make an informed decision about their contraceptive options.

A 68-year-old female is hospitalized due to a pulmonary embolism. She has a medical history of hypertension, type 2 diabetes mellitus, epilepsy, and schizophrenia. The patient is taking ramipril, olanzapine, metformin, gliclazide, and sodium valproate. The junior doctors are hesitant to start her on warfarin due to a potential interaction that could affect the dosage. Which medication is causing this interaction?
Your Answer: Sodium valproate
Explanation:P450 Enzyme System and its Inducers and Inhibitors
The P450 enzyme system is responsible for metabolizing drugs in the body. Induction of this system usually requires prolonged exposure to the inducing drug, unlike P450 inhibitors, which have rapid effects. Some drugs that induce the P450 system include antiepileptics like phenytoin and carbamazepine, barbiturates such as phenobarbitone, rifampicin, St John’s Wort, chronic alcohol intake, griseofulvin, and smoking, which affects CYP1A2 and is the reason why smokers require more aminophylline.
On the other hand, some drugs inhibit the P450 system, including antibiotics like ciprofloxacin and erythromycin, isoniazid, cimetidine, omeprazole, amiodarone, allopurinol, imidazoles such as ketoconazole and fluconazole, SSRIs like fluoxetine and sertraline, ritonavir, sodium valproate, and acute alcohol intake. It is important to be aware of these inducers and inhibitors as they can affect the metabolism and efficacy of drugs in the body. Proper dosing and monitoring can help ensure safe and effective treatment.

A 54-year-old man with a history of hypertension comes in for a check-up. During his annual health assessment, he undergoes a U&E, HbA1c, and cholesterol test. The results are as follows:
His blood pressure today is 128/78 mmHg. He takes ramipril 5mg od as his only regular medication.
Na+ 142 mmol/l
K+ 4.6 mmol/l
Urea 5.2 mmol/l
Creatinine 88 µmol/l
Total cholesterol 5.2 mmol/l
HbA1c 45 mmol/mol (6.3%)
His 10-year QRISK2 score is 7%. What is the most appropriate course of action based on these findings?Your Answer: Arrange a fasting glucose sample
Explanation:There is no need to take any action regarding his cholesterol as it is under control. Additionally, his blood pressure is also well managed. However, his HbA1c level is in the pre-diabetes range (42-47 mmol/mol) and requires further investigation. It is important to note that a HbA1c reading alone cannot rule out diabetes, and a fasting sample should be arranged for confirmation.
Type 2 diabetes mellitus can be diagnosed through a plasma glucose or HbA1c sample. The diagnostic criteria vary depending on whether the patient is experiencing symptoms or not. If the patient is symptomatic, a fasting glucose level of 7.0 mmol/l or higher or a random glucose level of 11.1 mmol/l or higher (or after a 75g oral glucose tolerance test) indicates diabetes. If the patient is asymptomatic, the same criteria apply but must be demonstrated on two separate occasions.
In 2011, the World Health Organization released supplementary guidance on the use of HbA1c for diagnosing diabetes. A HbA1c level of 48 mmol/mol (6.5%) or higher is diagnostic of diabetes mellitus. However, a HbA1c value of less than 48 mmol/mol (6.5%) does not exclude diabetes and may not be as sensitive as fasting samples for detecting diabetes. For patients without symptoms, the test must be repeated to confirm the diagnosis. It is important to note that increased red cell turnover can cause misleading HbA1c results.
There are certain conditions where HbA1c cannot be used for diagnosis, such as haemoglobinopathies, haemolytic anaemia, untreated iron deficiency anaemia, suspected gestational diabetes, children, HIV, chronic kidney disease, and people taking medication that may cause hyperglycaemia (such as corticosteroids).
Impaired fasting glucose (IFG) is defined as a fasting glucose level of 6.1 mmol/l or higher but less than 7.0 mmol/l. Impaired glucose tolerance (IGT) is defined as a fasting plasma glucose level less than 7.0 mmol/l and an OGTT 2-hour value of 7.8 mmol/l or higher but less than 11.1 mmol/l. People with IFG should be offered an oral glucose tolerance test to rule out a diagnosis of diabetes. A result below 11.1 mmol/l but above 7.8 mmol/l indicates that the person does not have diabetes but does have IGT.

A 50-year-old man presents to the clinic with painful red eyes and blurred vision. Upon examination, the eye appears red and tender with decreased visual acuity. There is no inflammation or discharge from the eyelids, and the anterior chamber is normal. The patient has a history of rheumatoid arthritis but is currently not receiving treatment. What is the probable diagnosis?
Your Answer: Anterior uveitis
Correct Answer: Scleritis
Explanation:Blepharitis is a condition characterized by inflammation of the margins of the eyelids, typically caused by the growth of eyelashes inwards. Symptoms include discomfort, redness, and dryness of the eyes, but no visual impairment. Urgent referral to ophthalmology is necessary if suspected. Treatment involves conservative measures such as regular eye care using warm compresses.
Understanding Scleritis: Causes, Symptoms, and Treatment
Scleritis is a condition that involves inflammation of the sclera, which is the white outer layer of the eye. This condition is typically non-infectious and can cause a red, painful eye. The most common risk factor associated with scleritis is rheumatoid arthritis, but it can also be linked to other conditions such as systemic lupus erythematosus, sarcoidosis, and granulomatosis with polyangiitis.
Symptoms of scleritis include a red eye, which is often accompanied by pain and discomfort. Patients may also experience watering and photophobia, as well as a gradual decrease in vision.
Treatment for scleritis typically involves the use of oral NSAIDs as a first-line treatment. In more severe cases, oral glucocorticoids may be used. For resistant cases, immunosuppressive drugs may be necessary, especially if there is an underlying associated disease. With proper treatment, most patients with scleritis can achieve relief from their symptoms and prevent further complications.

A 55-year-old woman presents with urgency and frequency. Three weeks ago she consulted with a colleague as she felt 'dry' during intercourse. She has been treated for urinary tract infections on multiple occasions in the past but urine culture is always negative. Her only medication is continuous hormone replacement therapy. A vaginal examination is performed which shows no evidence of vaginal atrophy and no masses are felt. An ultrasound is requested:
Both kidneys, spleen and liver are normal size. Outline of the bladder normal. 6 cm complex ovarian cyst noted on left ovary. Right ovary and uterus normal
What is the most appropriate next step?Your Answer: Trial topical oestrogen
Correct Answer: Urgent referral to gynaecology
Explanation:Investigation is necessary for any ovarian mass found in a woman who has undergone menopause.
Ovarian enlargement is typically diagnosed through ultrasound imaging, which can determine whether the cyst is simple or complex. Simple cysts are unilocular and more likely to be benign, while complex cysts are multilocular and more likely to be malignant. Management of ovarian enlargement depends on the patient’s age and symptoms. Younger women may be treated conservatively if the cyst is small and simple, with a repeat ultrasound scheduled in 8-12 weeks. Postmenopausal women, however, should always be referred to a gynecologist for assessment, as physiological cysts are unlikely in this population. It’s important to note that ovarian cancer can present with vague symptoms, leading to delayed diagnosis.

A 65-year-old man comes to your clinic complaining of myalgia in the shoulder girdle and low-grade fevers that have persisted for three weeks. He also mentions experiencing a brief loss of vision in his left eye. Based on the probable diagnosis, what laboratory test would be the most effective for diagnosis?
Your Answer: Erythrocyte sedimentation rate
Explanation:The diagnosis of polymyalgia rheumatica primarily relies on the detection of elevated inflammatory markers.
Among the laboratory tests, the most valuable in diagnosing PMR is the measurement of ESR levels.
Although CK and electromyography are commonly used in diagnosing muscle disorders, they may not be helpful in detecting PMR.
While CPR and white cell count may show increased levels in PMR, they are not specific enough to confirm the diagnosis.Polymyalgia Rheumatica: A Condition of Muscle Stiffness in Older People
Polymyalgia rheumatica (PMR) is a common condition that affects older people. It is characterized by muscle stiffness and elevated inflammatory markers. Although it is closely related to temporal arteritis, the underlying cause is not fully understood, and it does not appear to be a vasculitic process. PMR typically affects patients over the age of 60 and has a rapid onset, usually within a month. Patients experience aching and morning stiffness in proximal limb muscles, along with mild polyarthralgia, lethargy, depression, low-grade fever, anorexia, and night sweats.
To diagnose PMR, doctors look for raised inflammatory markers, such as an ESR of over 40 mm/hr. Creatine kinase and EMG are normal. Treatment for PMR involves prednisolone, usually at a dose of 15mg/od. Patients typically respond dramatically to steroids, and failure to do so should prompt consideration of an alternative diagnosis.

A 51-year-old woman presents with non-specific abdominal discomfort that has been bothering her for the past 2 months. She also reports experiencing loose stools up to three times a day for the past month, despite previously having solid stools once daily. She denies any weight loss or blood in her stool. Upon examination, her abdomen is soft and nontender, and she has normal urine dip results. Blood tests, including a CA-125 and coeliac screen, and a faecal calprotectin test all come back within the normal range. Although you suspect irritable bowel syndrome, the patient is worried about the possibility of colorectal cancer. What is the best course of action?
Your Answer: Offer reassurance
Correct Answer: Faecal immunochemical test (FIT)
Explanation:If a patient shows new symptoms of possible colorectal cancer but does not meet the 2-week criteria, it is recommended to undergo the FIT test. In the case of a patient experiencing unexplained abdominal pain and a change in bowel habit, a FIT test is the most appropriate next step, according to NICE guidance, especially considering the patient’s age and the absence of rectal bleeding. It is not advisable to simply suggest diet changes or reassure the patient without conducting the necessary tests, as her symptoms require complete investigation. Repeating a faecal calprotectin level is unlikely to be helpful and may only delay the patient from receiving the appropriate support.
Referral Guidelines for Colorectal Cancer
Colorectal cancer is a serious condition that requires prompt diagnosis and treatment. In 2015, the National Institute for Health and Care Excellence (NICE) updated their referral guidelines for patients suspected of having colorectal cancer. According to these guidelines, patients who are 40 years or older with unexplained weight loss and abdominal pain, 50 years or older with unexplained rectal bleeding, or 60 years or older with iron deficiency anemia or change in bowel habit should be referred urgently to colorectal services for investigation. Additionally, patients who test positive for occult blood in their feces should also be referred urgently.
An urgent referral should also be considered for patients who have a rectal or abdominal mass, unexplained anal mass or anal ulceration, or are under 50 years old with rectal bleeding and any of the following unexplained symptoms/findings: abdominal pain, change in bowel habit, weight loss, or iron deficiency anemia.
The NHS offers a national screening program for colorectal cancer, which involves sending eligible patients aged 60 to 74 years in England and 50 to 74 years in Scotland FIT tests through the post. FIT is a type of fecal occult blood test that uses antibodies to detect and quantify the amount of human blood in a single stool sample. Patients with abnormal results are offered a colonoscopy.
The FIT test is also recommended for patients with new symptoms who do not meet the 2-week criteria listed above. For example, patients who are 50 years or older with unexplained abdominal pain or weight loss, under 60 years old with changes in their bowel habit or iron deficiency anemia, or 60 years or older who have anemia even in the absence of iron deficiency. Early detection and treatment of colorectal cancer can significantly improve patient outcomes, making it important to follow these referral guidelines.

You are asked to review an elderly nursing home resident who has generalised inflammation of his oropharynx and is finding it difficult to eat. His past history of note includes the use of a steroid inhaler for chronic obstructive pulmonary disease (COPD). On examination, there are areas of erythema and a number of white plaques accompanied by some white, curd-like material.
Which diagnosis best fits this clinical picture?Your Answer: Oropharyngeal candidiasis
Explanation:Differential Diagnosis of Oral Lesions: Candidiasis, HIV Infection, Hairy Leukoplakia, Darier’s Disease, and Leukoedema
Oral lesions can present in various forms and have different underlying causes. In the case of an elderly man with long-term use of a steroid inhaler for COPD, poor oral hygiene, and possibly poorly fitting prosthetics, the most likely diagnosis is oropharyngeal candidiasis. This yeast-like fungal infection can be treated with antifungal medication, applied to the oral mucosa and any removable oral prostheses, and soaking the latter in an antifungal denture-soaking solution.
HIV infection can also cause oral lesions, primarily in patients with advanced disease. Candidiasis is a common opportunistic infection in these patients, but hairy leukoplakia, associated with Epstein-Barr virus, can also occur. Hairy leukoplakia presents as painless white lesions on the tongue or buccal mucosa, with a characteristic hairy appearance that cannot be scraped off.
Darier’s disease is a rare genetic disorder that causes greasy hyperkeratotic papules in seborrhoeic regions, nail abnormalities, and mucous membrane changes. Mucosal lesions are found in approximately 15% of patients, appearing as white papules with a central depression, most commonly in the mouth.
Leukoedema is a benign condition characterized by a blue, grey, or white appearance of the oral mucosa, with wrinkled, streaky lesions, mostly found on the inside of the cheeks. It is more common and pronounced in smokers.
In summary, the differential diagnosis of oral lesions includes candidiasis, HIV infection, hairy leukoplakia, Darier’s disease, and leukoedema. A thorough examination and consideration of the patient’s medical history can help determine the underlying cause and appropriate treatment.

A 65-year-old woman is discharged following an uncomplicated renal transplant for end-stage renal failure from hypertension. She received a kidney with 4 out of 6 mismatched human leukocyte antigen (HLA) and is taking the appropriate medications. Thirty days postoperatively, she developed watery loose stools, followed by a skin rash that is itchy, painful and red. On examination, she has a red-violet rash affecting her hands and feet.
Investigations reveal the following:
Investigation Result Normal value
Haemoglobin (Hb) 131 g/l 115–155 g/l
White cell count (WCC) 5.4 × 109/l 4.0–11.0 × 109/l
Platelets (PLT) 280 ×109/l 150–400 × 109/l
Sodium (Na+) 139 mmol/l 135–145 mmol/l
Potassium (K+) 4.0 mmol/l 3.5–5.0 mmol/l
Urea 15.1 mmol/l 2.5–6.5 mmol/l
Creatinine (Cr) 170 μmol/l 50–120 µmol/l
Alanine aminotransferase (ALT) 54 IU/l 7–55 IU/l
Alkaline phosphatase (ALP) 165 IU/l 30–130 IU/l
Bilirubin 62 µmol/l 2–17 µmol/l
Which of the following is the most likely diagnosis?Your Answer: Graft-versus-host disease
Explanation:Differential Diagnosis for a Patient with Watery Diarrhea and Rash after Renal Transplantation
Graft-versus-host disease (GVHD) is a potential complication of solid organ transplantation, with a mortality rate of 75%. It typically presents with watery diarrhea, a painful red-violet rash, and raised bilirubin. Diagnosis is obtained through biopsy, and treatment involves immunosuppressants such as tacrolimus and methylprednisolone.
Acute viral hepatitis is another possible cause of diarrhea and jaundice, but the patient’s normal ALT and atypical symptoms make it unlikely. Azathioprine toxicity can cause bone marrow suppression, while Sjögren syndrome causes dry eyes and xerostomia, neither of which fit this patient’s presentation.
Viral gastroenteritis is a consideration, but the presence of a painful/itchy rash and raised bilirubin suggests a need for further investigation. Given the recent renal transplant, a high degree of suspicion for GVHD and other potential complications is warranted.

A 21-year-old female presents for a follow-up after a medical termination of pregnancy at 8 weeks gestation. She is considering getting a Nexplanon implant. When is it appropriate to insert Nexplanon in this situation?
Your Answer: Immediately
Explanation:Implanon and Nexplanon are subdermal contraceptive implants that slowly release the progestogen hormone etonogestrel to prevent ovulation and thicken cervical mucus. Nexplanon is the newer version and has a redesigned applicator to prevent deep insertions and is radiopaque for easier location. It is highly effective with a failure rate of 0.07/100 women-years and lasts for 3 years. It does not contain estrogen, making it suitable for women with a past history of thromboembolism or migraine. It can be inserted immediately after a termination of pregnancy. However, a trained professional is needed for insertion and removal, and additional contraceptive methods are required for the first 7 days if not inserted on days 1 to 5 of a woman’s menstrual cycle.
The main disadvantage of these implants is irregular and heavy bleeding, which can be managed with a co-prescription of the combined oral contraceptive pill. Other adverse effects include headache, nausea, and breast pain. Enzyme-inducing drugs such as certain antiepileptic and rifampicin may reduce the efficacy of Nexplanon, and women should switch to a method unaffected by enzyme-inducing drugs or use additional contraception until 28 days after stopping the treatment.
There are also contraindications for using these implants, such as ischaemic heart disease/stroke, unexplained, suspicious vaginal bleeding, past breast cancer, severe liver cirrhosis, and liver cancer. Current breast cancer is a UKMEC 4 condition, which represents an unacceptable risk if the contraceptive method is used. Overall, these implants are a highly effective and long-acting form of contraception, but they require careful consideration of the potential risks and contraindications.

A 68-year-old male is prescribed colchicine to alleviate his gout symptoms that are not responding to diclofenac. What is the most crucial side effect to caution him about?
Your Answer: Heartburn
Correct Answer: Diarrhoea
Explanation:Gout is caused by chronic hyperuricaemia and is managed acutely with NSAIDs or colchicine. Urate-lowering therapy (ULT) is recommended for patients with >= 2 attacks in 12 months, tophi, renal disease, uric acid renal stones, or prophylaxis if on cytotoxics or diuretics. Allopurinol is first-line ULT, with an initial dose of 100 mg od and titrated to aim for a serum uric acid of < 300 µmol/l. Lifestyle modifications include reducing alcohol intake, losing weight if obese, and avoiding high-purine foods. Consideration should be given to stopping precipitating drugs and losartan may be suitable for patients with coexistent hypertension.

Which of the following is linked to a favorable prognosis in individuals with schizophrenia?
Your Answer: Lack of obvious precipitant
Correct Answer: Acute onset
Explanation:A poor prognosis is often linked to a gradual onset rather than an acute one.
Schizophrenia is a mental disorder that can have varying prognoses depending on certain factors. Some indicators associated with a poor prognosis include a strong family history of the disorder, a gradual onset of symptoms, a low IQ, a prodromal phase of social withdrawal, and a lack of an obvious precipitant. These factors can contribute to a more severe and chronic course of the illness, making it more difficult to manage and treat. It is important for individuals with schizophrenia and their loved ones to be aware of these indicators and seek appropriate treatment and support.

A 65-year-old man with chronic schizophrenia complains of nausea and vomiting. He is given metoclopramide to alleviate his symptoms. However, after twenty minutes, he becomes restless and experiences severe oculogyric crises and oromandibular dystonia. What medication should be prescribed in this situation?
Your Answer: Procyclidine
Explanation:Procyclidine is the usual treatment for acute dystonia caused by antipsychotics. This patient’s acute dystonic reaction can be reversed with procyclidine, which is an anticholinergic medication that blocks acetylcholine. This medication can alleviate muscle stiffness, sweating, and excessive saliva production, and can also improve walking ability in individuals with Parkinson’s disease. The patient most likely developed this reaction due to long-term use of antipsychotics and subsequent administration of metoclopramide. While midazolam and lorazepam can relieve anxiety, they are not effective in treating dystonia.
Antipsychotics are a group of drugs used to treat schizophrenia, psychosis, mania, and agitation. They are divided into two categories: typical and atypical antipsychotics. The latter were developed to address the extrapyramidal side-effects associated with the first generation of typical antipsychotics. Typical antipsychotics work by blocking dopaminergic transmission in the mesolimbic pathways through dopamine D2 receptor antagonism. They are associated with extrapyramidal side-effects and hyperprolactinaemia, which are less common with atypical antipsychotics.
Extrapyramidal side-effects (EPSEs) are common with typical antipsychotics and include Parkinsonism, acute dystonia, sustained muscle contraction, akathisia, and tardive dyskinesia. The latter is a late onset of choreoathetoid movements that may be irreversible and occur in 40% of patients. The Medicines and Healthcare products Regulatory Agency has issued specific warnings when antipsychotics are used in elderly patients, including an increased risk of stroke and venous thromboembolism. Other side-effects include antimuscarinic effects, sedation, weight gain, raised prolactin, impaired glucose tolerance, neuroleptic malignant syndrome, reduced seizure threshold, and prolonged QT interval.

A 38-year-old woman of Afro-Caribbean origin presents to the Oncology Clinic under the 2-week-wait pathway. She has been noticing some lumps on her neck that are classified as painless, nontender, asymmetrical lymphadenopathy. She complains of increasing night sweats and has noticed some pain when drinking alcohol.
Given the likely diagnosis, which one of the following features is associated with a poor prognosis?Your Answer: Night sweats
Explanation:Understanding Hodgkin’s Lymphoma: Symptoms and Prognosis Factors
Hodgkin’s lymphoma is a type of cancer that affects the lymphatic system. One of the most common symptoms of this malignancy is painless, non-tender, asymmetrical lymphadenopathy. However, the presence of night sweats, fever, and weight loss can also indicate a diagnosis of Hodgkin’s lymphoma. Patients of Afro-Caribbean origin may have a worse prognosis in acute lymphoblastic leukaemia, but not in Hodgkin’s lymphoma. Alcohol-induced pain is a characteristic feature of some cases of Hodgkin’s lymphoma, but it has not been associated with a poor prognosis. Asymmetrical lymphadenopathy is a typical feature of Hodgkin’s lymphoma and has not been linked to a worse prognosis. Finally, while female sex has not been associated with poor prognosis, some studies suggest that male sex could be connected with a poorer outcome.

A 4-year-old child is presented for surgery due to the mother's observation of 'cross-eyed' appearance. The corneal light reflection test confirms the diagnosis. What is the best course of action?
Your Answer: Refer to paediatric physiotherapy for eye movement exercises
Correct Answer: Refer to ophthalmology
Explanation:It is recommended to refer children who have a squint to ophthalmology for further evaluation.
Squint, also known as strabismus, is a condition where the visual axes are misaligned. There are two types of squints: concomitant and paralytic. Concomitant squints are more common and are caused by an imbalance in the extraocular muscles. On the other hand, paralytic squints are rare and are caused by the paralysis of extraocular muscles. It is important to detect squints early on as they can lead to amblyopia, where the brain fails to process inputs from one eye and favours the other eye over time.
To detect a squint, a corneal light reflection test can be performed by holding a light source 30cm from the child’s face to see if the light reflects symmetrically on the pupils. The cover test is also used to identify the nature of the squint. This involves asking the child to focus on an object, covering one eye, and observing the movement of the uncovered eye. The test is then repeated with the other eye covered.
If a squint is detected, it is important to refer the child to secondary care. Eye patches may also be used to help prevent amblyopia.

Question 30
Correct

A 35-year-old male is admitted to hospital after an overdose of paracetamol. He waited until his children had gone to school and his wife had left for work before taking 100 tablets. He did not drink any alcohol and rarely has any. He had taken annual leave from the steady job in a factory and had left a note. His wife had forgotten something so returned from work earlier than usual and found him semi-conscious.
After treatment for his physical health he tells you that he does not regret the attempt but feels bad that he has put his children through enough seeing him in hospital. He is not religious. His wife is not very supportive of him and thinks he is 'attention-seeking'. He has no other family or friends locally. He has struggled with symptoms of depression for a number of months and has never sought help, but otherwise is physically well.
During your assessment, you want to ascertain any protective factors.
Which of the following is a protective factor in this case?Your Answer: She has children at home
Explanation:Completed suicide can be prevented by certain protective factors such as having social support, religious beliefs, having children at home, and regretting a previous attempt. It is important to note that the duration of mental illness is not a determining factor, but having a mental illness, especially depression, increases the risk. Alcohol misuse is also a risk factor, but in this scenario, the fact that the person does not drink much alcohol is not particularly protective. The individual in the scenario lacks social support and is not religious, making those options incorrect. However, having children present at home is a protective factor.
Suicide Risk Factors and Protective Factors
Suicide risk assessment is a common practice in psychiatric care, with patients being stratified into high, medium, or low risk categories. However, there is a lack of evidence on the positive predictive value of individual risk factors. A review in the BMJ concluded that such assessments may not be useful in guiding decision-making, as 50% of suicides occur in patients deemed low risk. Nevertheless, certain factors have been associated with an increased risk of suicide, including male sex, history of deliberate self-harm, alcohol or drug misuse, mental illness, depression, schizophrenia, chronic disease, advancing age, unemployment or social isolation, and being unmarried, divorced, or widowed.
If a patient has attempted suicide, there are additional risk factors to consider, such as efforts to avoid discovery, planning, leaving a written note, final acts such as sorting out finances, and using a violent method. On the other hand, there are protective factors that can reduce the risk of suicide, such as family support, having children at home, and religious belief. It is important to consider both risk and protective factors when assessing suicide risk and developing a treatment plan.
