A 56-year-old man presents with progressively worsening dysphagia, which is worse for food than liquid. He has lost several stones in weight and, on examination, he is cachexia. An oesophagogastroduodenoscopy (OGD) confirms oesophageal cancer.
Which of the following is the strongest risk factor for oesophageal adenocarcinoma?Your Answer: Barrett's oesophagus
Explanation:Understanding Risk Factors for Oesophageal Cancer
Oesophageal cancer is a type of cancer that is becoming increasingly common. It often presents with symptoms such as dysphagia, weight loss, and retrosternal chest pain. Adenocarcinomas, which are the most common type of oesophageal cancer, typically develop in the lower third of the oesophagus due to inflammation related to gastric reflux.
One of the risk factors for oesophageal cancer is Barrett’s oesophagus, which is the metaplasia of the squamous epithelium of the lower oesophagus when exposed to an acidic environment. This adaptive change significantly increases the risk of malignant change. Treatment options for Barrett’s oesophagus include ablative or excisional therapy and acid-lowering medications. Follow-up with repeat endoscopy every 2–5 years is required.
Blood group A is not a risk factor for oesophageal cancer, but it is associated with a 20% higher risk of stomach cancer compared to those with blood group O. A diet low in calcium is also not a risk factor for oesophageal carcinoma, but consumption of red meat is classified as a possible cause of oesophageal cancer. Those with the highest red meat intake have a 57% higher risk of oesophageal squamous cell carcinoma compared to those with the lowest intake.
Ulcerative colitis is not a risk factor for oesophageal cancer, but it is a risk factor for bowel cancer. On the other hand, alcohol is typically a risk factor for squamous cell carcinomas. Understanding these risk factors can help individuals take steps to reduce their risk of developing oesophageal cancer.

A 55-year-old woman presents with symptoms of nausea and vomiting. She has been diagnosed with inoperable cancer and is experiencing pain from infiltration of the posterior abdominal wall. Currently, her pain is being managed effectively with Kapake (codeine 30 mg and paracetamol 500 mg), taken two tablets four times per day.
What is the optimal approach for managing her pain?Your Answer: Subcutaneous diamorphine by continuous infusion
Explanation:Choosing the Best Analgesia for a Patient with Inoperable Carcinoma
When a patient has inoperable carcinoma and requires opiate analgesia, it is important to choose the most effective method of administration. In the case of a patient who is vomiting, parenteral analgesia is necessary. Subcutaneous diamorphine administered through continuous infusion is the best option for achieving adequate analgesia while also allowing for effective dose titration.
Other options, such as fentanyl patches, are not ideal for titration as they are used for 72 hours and are typically reserved for patients with stable opiate usage. Intramuscular pethidine has a delayed onset and prolonged effect, which is not ideal when the patient’s opiate requirements are unknown. Oral morphine is unlikely to be tolerated in a vomiting patient, and non-steroidal anti-inflammatory drugs are unlikely to provide sufficient pain relief in this case.
In summary, subcutaneous diamorphine administered through continuous infusion is the most effective and appropriate method of analgesia for a patient with inoperable carcinoma who is vomiting and requires opiate pain relief.

A 17-year-old boy is rushed to the Emergency department following drug use at a party.
What signs indicate that he may have ingested Ecstasy (MDMA)?Your Answer: Hypernatraemia
Correct Answer: Pyrexia
Explanation:Symptoms of Ecstasy Overdose
Ecstasy overdose can lead to a range of symptoms, including hyperthermia, hypertension, hyponatremia, and respiratory alkalosis. Hyperthermia is characterized by an abnormally high body temperature, which can cause damage to organs and tissues. Hypertension, or high blood pressure, can lead to a range of health problems, including heart disease and stroke. Hyponatremia is caused by excessive drinking of water, which can lead to a condition known as syndrome of inappropriate antidiuretic hormone (SIADH). This can cause a range of symptoms, including confusion, seizures, and coma. Respiratory alkalosis is characterized by an increase in blood pH, which can cause a range of symptoms, including dizziness, confusion, and seizures. Pinpoint pupils may also suggest the presence of opiates.

A 30-year-old Afro-Caribbean woman presents with bilateral ankle and wrist pain that has been gradually worsening over the past 5 days. She complains of fatigue and feelings of lack of energy. She mentions a dry cough and shortness of breath on exertion, lasting for more than a year. On examination, her vital signs are within normal limits, except for the presence of a mild fever. There are several reddish, painful, and tender lumps on the anterior of the lower legs. A chest X-ray shows bilateral hilar masses of ,1 cm in diameter.
Which of the following test results is most likely to be found in this patient?Your Answer: Elevated double-stranded (ds) DNA antibody
Correct Answer: Elevated serum angiotensin-converting enzyme (ACE)
Explanation:Differentiating between Elevated Serum Markers in a Patient with Arthropathy and Hilar Lymphadenopathy
The presence of arthropathy and hilar lymphadenopathy in a patient can be indicative of various underlying conditions. In this case, the patient’s elevated serum markers can help differentiate between potential diagnoses.
Elevated serum angiotensin-converting enzyme (ACE) is a common finding in sarcoidosis, which is likely the cause of the patient’s symptoms. Bilateral hilar lymphadenopathy with or without pulmonary fibrosis is the most typical radiological sign of sarcoidosis. Additionally, acute arthropathy in sarcoidosis patients, known as Löfgren syndrome, is associated with erythema nodosum and fever.
On the other hand, elevated cytoplasmic anti-neutrophil cytoplasmic antibody (c-ANCA) is present in granulomatosis with polyangiitis (GPA), which presents with necrotising granulomatous lesions in the upper and lower respiratory tract and renal glomeruli. It is not typically associated with hilar lymphadenopathy.
Hyperuricaemia and elevated double-stranded (ds) DNA antibody are not relevant to this case, as they are not associated with the patient’s symptoms. Hyperglycaemia is also not a factor in this case.
In conclusion, the combination of arthropathy and hilar lymphadenopathy can be indicative of various underlying conditions. Elevated serum markers can help differentiate between potential diagnoses, such as sarcoidosis and GPA.

A 32-year-old woman who is at 16 weeks gestation attends her antenatal appointment and is given the option to undergo the quadruple test for chromosomal disorders. After consenting, she has a blood test and is later informed that the results indicate a higher likelihood of Down's syndrome in the fetus. The patient is now invited to discuss the next course of action. What is the probable outcome of the quadruple test?
Your Answer: Decreased AFP, decreased oestriol, increased hCG, increased inhibin A
Explanation:The correct result for the quadruple test in a patient with Down’s syndrome is a decrease in AFP and oestriol, and an increase in hCG and inhibin A. This test is recommended by NICE for pregnant patients between 15-20 weeks gestation. If the screening test shows an increased risk, further diagnostic tests such as NIPT, amniocentesis, or chorionic villous sampling may be offered to confirm the diagnosis. It is important to note that a pattern of decreased AFP, decreased oestriol, decreased hCG, and normal inhibin A is suggestive of an increased risk of Edward’s syndrome. Increased AFP, increased oestriol, decreased hCG, and decreased inhibin A or any other combination of abnormal results may not be indicative of Down’s syndrome.
NICE updated guidelines on antenatal care in 2021, recommending the combined test for screening for Down’s syndrome between 11-13+6 weeks. The test includes nuchal translucency measurement, serum B-HCG, and pregnancy-associated plasma protein A (PAPP-A). The quadruple test is offered between 15-20 weeks for women who book later in pregnancy. Results are interpreted as either a ‘lower chance’ or ‘higher chance’ of chromosomal abnormalities. If a woman receives a ‘higher chance’ result, she may be offered a non-invasive prenatal screening test (NIPT) or a diagnostic test. NIPT analyzes cell-free fetal DNA in the mother’s blood and has high sensitivity and specificity for detecting chromosomal abnormalities. Private companies offer NIPT screening from 10 weeks gestation.

A 16-year-old girl visits your GP practice seeking contraception. After counseling her, you both agree that the implant would be the most suitable option. You believe that she has the ability to make this decision and give her consent for the insertion. However, during previous consultations, you have found her to lack capacity for certain decisions and have involved her parents. According to the GMC, what is necessary to proceed with the implant insertion?
Your Answer: Just the patient's consent.
Explanation:Capacity to make decisions is dependent on both time and the individual’s ability to make decisions. If the patient did not have the capacity to make a decision in the past, but currently has the capacity to do so, their consent is the only one required. It is advisable to involve parents in the decision-making process for pediatric patients, especially in cases involving contraception. However, if the patient is not convinced, the treatment can still proceed as long as they have the capacity to make the decision. If there are doubts, it is good practice to involve another healthcare team member, but if the patient is deemed capable of making the decision, their capacitous consent is sufficient according to the GMC. There is no requirement for a time gap between consultations to allow for decision-making.
Guidelines for Obtaining Consent in Children
The General Medical Council has provided guidelines for obtaining consent in children. According to these guidelines, young people who are 16 years or older can be treated as adults and are presumed to have the capacity to make decisions. However, for children under the age of 16, their ability to understand what is involved determines whether they have the capacity to decide. If a competent child refuses treatment, a person with parental responsibility or the court may authorize investigation or treatment that is in the child’s best interests.
When it comes to providing contraceptives to patients under 16 years of age, the Fraser Guidelines must be followed. These guidelines state that the young person must understand the professional’s advice, cannot be persuaded to inform their parents, is likely to begin or continue having sexual intercourse with or without contraceptive treatment, and will suffer physical or mental health consequences without contraceptive treatment. Additionally, the young person’s best interests require them to receive contraceptive advice or treatment with or without parental consent.
Some doctors use the term Fraser competency when referring to contraception and Gillick competency when referring to general issues of consent in children. However, rumors that Victoria Gillick removed her permission to use her name or applied copyright have been debunked. It is important to note that in Scotland, those with parental responsibility cannot authorize procedures that a competent child has refused.

A 32-year-old male presents with a football-related injury. He complains of acute pain in his right calf that began with a popping sound during running. You suspect an Achilles tendon rupture and proceed to perform Simmonds' Triad examination. What does this assessment entail?
Your Answer: Calf squeeze test, observation of the angle of declination, palpation of the tendon
Explanation:To assess for an Achilles tendon rupture, Simmonds’ triad can be used. This involves three components: palpating the Achilles tendon to check for a gap, observing the angle of declination at rest to see if the affected foot is more dorsiflexed than the other, and performing the calf squeeze test to see if squeezing the calf causes the foot to plantarflex as expected. It’s important to note that struggling to stand on tiptoes or having an abnormal gait are not part of Simmonds’ triad.
Achilles tendon disorders are a common cause of pain in the back of the heel. These disorders can include tendinopathy, partial tears, and complete ruptures of the Achilles tendon. Certain factors, such as the use of quinolone antibiotics and high cholesterol levels, can increase the risk of developing these disorders. Symptoms of Achilles tendinopathy typically include gradual onset of pain that worsens with activity, as well as morning stiffness. Treatment for this condition usually involves pain relief, reducing activities that exacerbate the pain, and performing calf muscle eccentric exercises.
In contrast, an Achilles tendon rupture is a more serious condition that requires immediate medical attention. This type of injury is often caused by sudden, forceful movements during sports or running. Symptoms of an Achilles tendon rupture include an audible popping sound, sudden and severe pain in the calf or ankle, and an inability to walk or continue the activity. To help diagnose an Achilles tendon rupture, doctors may use Simmond’s triad, which involves examining the foot for abnormal angles and feeling for a gap in the tendon. Ultrasound is typically the first imaging test used to confirm a diagnosis of Achilles tendon rupture. If a rupture is suspected, it is important to seek medical attention from an orthopaedic specialist as soon as possible.

A 30-year-old multiparous female at 10 weeks gestation visits her general practitioner to book her pregnancy. She has a history of gestational diabetes and returns the next day for an oral glucose tolerance test. Her blood results show a fasting glucose level of 7.2 mmol/L and a 2-hour glucose level of 8.9 mmol/L. What is the recommended course of action based on these findings?
Your Answer: Patient to be started on metformin
Correct Answer: Patient to be started on insulin
Explanation:If the fasting glucose level is equal to or greater than 7 mmol/l at the time of gestational diabetes diagnosis, immediate administration of insulin (with or without metformin) is necessary. For patients with a fasting plasma glucose level below 7.0 mmol/L, a trial of diet and exercise with follow-up in 1-2 weeks is appropriate. Within a week of diagnosis, the patient should be seen in a joint antenatal and diabetic clinic. Statins are not recommended during pregnancy due to potential congenital abnormalities resulting from reduced cholesterol synthesis. Sitagliptin, a DPP-4 inhibitor, is also not recommended for use during pregnancy or breastfeeding.
Gestational diabetes is a common medical disorder affecting around 4% of pregnancies. Risk factors include a high BMI, previous gestational diabetes, and family history of diabetes. Screening is done through an oral glucose tolerance test, and diagnostic thresholds have recently been updated. Management includes self-monitoring of blood glucose, diet and exercise advice, and medication if necessary. For pre-existing diabetes, weight loss and insulin are recommended, and tight glycemic control is important. Targets for self-monitoring include fasting glucose of 5.3 mmol/l and 1-2 hour post-meal glucose levels.

A client is given local anaesthetic after a procedure. The physician injects 25 ml of 1.5% lidocaine.
What is the total amount of lidocaine in milligrams?Your Answer: 400mg
Explanation:The strength of the solution is such that 2g are dissolved in every 100ml. This means that for every 100 ml of solution, 2g of lidocaine are dissolved. If 20 ml of the solution is infiltrated (which is one-fifth of 100ml), then the amount of lidocaine present in the infiltrated solution can be calculated by dividing 2g (which is equal to 2000mg) by 5.
Local anaesthetic agents include lidocaine, cocaine, bupivacaine, and prilocaine. Lidocaine is an amide that is metabolized in the liver, protein-bound, and renally excreted. Toxicity can occur with IV or excess administration, and increased risk is present with liver dysfunction or low protein states. Cocaine is rarely used in mainstream surgical practice and is cardiotoxic. Bupivacaine has a longer duration of action than lignocaine and is cardiotoxic, while levobupivacaine is less cardiotoxic. Prilocaine is less cardiotoxic and is the agent of choice for intravenous regional anesthesia. Adrenaline can be added to local anesthetic drugs to prolong their duration of action and permit higher doses, but it is contraindicated in patients taking MAOI’s or tricyclic antidepressants.

You are a medical senior house officer seeing a patient called Edith with your consultant. Edith is a very frail 88-year-old lady with urinary sepsis and a history of metastatic bladder carcinoma. Your consultant completes her ward round and is of the opinion that cardiopulmonary resuscitation (CPR) would be unsuccessful if Edith were to have a cardiac arrest. After the round, a nurse asks you to complete a Do Not Attempt Resuscitation order (DNAR), which will mean that Edith would not undergo CPR in the event of a cardiac arrest. Edith does not currently have mental capacity to make decisions about her care. You have not discussed resuscitation with Edith or her family and do not have any more information available to you at this time. Her son has been appointed Power of Attorney, which includes provision for him to make decisions about Edith’s welfare and medical care.
Select the most appropriate action to take in this case.Your Answer: Complete the DNAR form only if you obtain consent from Edith’s Power of Attorney
Correct Answer: Attempt to contact Edith’s son to discuss the DNACPR order first and then complete the DNAR form
Explanation:Making Decisions about DNACPR and DNAR Orders for Patients without Capacity
When a patient lacks capacity, decisions about their care must be made by their appointed Lasting Power of Attorney (LPA) for health and welfare. In the case of Edith, a decision has been made by the consultant that CPR would not be successful, and a DNACPR order must be put in place to avoid futile attempts at resuscitation. It is good practice to discuss this decision with Edith’s son, who has been assigned as her LPA. However, if he cannot be reached, the order must still be put in place, with continued attempts to contact him for discussion.
It is important to note that a DNAR form should only be completed when the patient has regained mental capacity and can consent to the decision. In Edith’s case, a senior clinician has already determined that attempts at resuscitation would be unsuccessful, and waiting for the consultant to sign the DNAR form may cause harm to Edith if she suffers a cardiac arrest before it is completed.
While it is important to involve the LPA in discussions about the patient’s care, the decision on whether to attempt CPR is ultimately a clinical decision made by the multidisciplinary team. If there is disagreement between the healthcare team and the LPA, a second opinion can be sought, and if necessary, the Court of Protection may be asked to make a declaration. However, the priority should always be the patient’s best interest and avoiding unnecessary distress or harm.

A 3-month-old boy is presented to surgery with vomiting and poor feeding. The mother reports a strong odor in his urine, indicating a possible urinary tract infection. What is the best course of action for management?
Your Answer: Refer immediately to hospital
Explanation:Urinary tract infections (UTI) are more common in boys until 3 months of age, after which the incidence is substantially higher in girls. Presentation in childhood depends on age, with infants showing poor feeding, vomiting, and irritability, younger children showing abdominal pain, fever, and dysuria, and older children showing dysuria, frequency, and haematuria. NICE guidelines recommend checking urine samples in children with symptoms or signs suggestive of a UTI, unexplained fever of 38°C or higher, or an alternative site of infection but who remain unwell. Urine collection should be done through clean catch or urine collection pads, and invasive methods should only be used if non-invasive methods are not possible. Management includes referral to a paediatrician for infants less than 3 months old, admission to hospital for children aged more than 3 months old with an upper UTI, and oral antibiotics for 3-10 days for children aged more than 3 months old with a lower UTI. Antibiotic prophylaxis is not given after the first UTI but should be considered with recurrent UTIs.

In which part of the gastrointestinal system is water mainly taken up?
Your Answer: Small intestine
Explanation:The Function of the Large Intestine
Although many people believe that the primary function of the large intestine is to absorb water, this is not entirely accurate. In fact, the majority of water and fluids that are ingested or secreted are actually reabsorbed in the small intestine, which is located before the large intestine in the digestive tract. While the large intestine does play a role in absorbing some water and electrolytes, its primary function is to store and eliminate waste products from the body. This is achieved through the formation of feces, which are then eliminated through the rectum and anus. Overall, while the large intestine is an important part of the digestive system, its function is more complex than simply absorbing water.

A 27-year-old man presents to his GP with a painless lump in his right testicle that has been present for 4 months and has gradually increased in size. He has a medical history of type one diabetes mellitus, coeliac disease, and infertility. Additionally, he is a heavy smoker with a 20 pack-year history and consumes 30 units of alcohol per week. The GP suspects testicular cancer and refers the patient via the two-week-wait pathway. What is the most significant risk factor for this condition based on the patient's history?
Your Answer: Infertility
Explanation:Men who are infertile have a threefold higher risk of developing testicular cancer. This is important to consider for males between the ages of 20 and 30 who may be at risk. Risk factors for testicular cancer include undescended testes, a family history of the disease, Klinefelter’s syndrome, mumps orchitis, and infertility. Therefore, infertility is the correct answer.
Coeliac disease is an autoimmune condition that causes inflammation when gluten is consumed. It is a risk factor for osteoporosis, pancreatitis, lymphoma, and upper gastrointestinal cancer, but not testicular cancer.
Excessive alcohol consumption is a risk factor for various types of cancer, such as breast, upper, and lower gastrointestinal cancer, but not testicular cancer.
Smoking is a significant risk factor for several types of cancer, particularly lung cancer. It is the most preventable cause of cancer in the UK. However, it is not associated with testicular cancer.
Diabetes mellitus is also a risk factor for various types of cancer, such as liver, endometrial, and pancreatic cancer. However, it is not associated with testicular cancer.
Understanding Testicular Cancer
Testicular cancer is a type of cancer that commonly affects men between the ages of 20 and 30. Germ-cell tumors are the most common type of testicular cancer, accounting for around 95% of cases. These tumors can be divided into seminomas and non-seminomas, which include embryonal, yolk sac, teratoma, and choriocarcinoma. Other types of testicular cancer include Leydig cell tumors and sarcomas. Risk factors for testicular cancer include infertility, cryptorchidism, family history, Klinefelter’s syndrome, and mumps orchitis.
The most common symptom of testicular cancer is a painless lump, although some men may experience pain. Other symptoms may include hydrocele and gynaecomastia, which occurs due to an increased oestrogen:androgen ratio. Tumor markers such as hCG, AFP, and beta-hCG may be elevated in germ cell tumors. Ultrasound is the first-line diagnostic tool for testicular cancer.
Treatment for testicular cancer depends on the type and stage of the tumor. Orchidectomy, chemotherapy, and radiotherapy may be used. Prognosis for testicular cancer is generally excellent, with a 5-year survival rate of around 95% for seminomas and 85% for teratomas if caught at Stage I. It is important for men to perform regular self-examinations and seek medical attention if they notice any changes or abnormalities in their testicles.

A 28-year-old obese man presents to clinic. He is found to have a body mass index (BMI) of 36 kg/m2 and wants advice regarding treatment of his obesity.
Which of the following pertains to the treatment of obesity?Your Answer: Weight loss will be very slow at first when only glycogen breaks down, but this is followed 3–4 weeks later by a period of incremental weight loss due to breakdown of adipose tissue
Correct Answer: Orlistat causes weight loss by inhibiting pancreatic and gastric lipase
Explanation:Misconceptions and Clarifications about Weight Loss Methods
Orlistat: A common misconception is that Orlistat causes weight loss by reducing appetite. In reality, it inhibits pancreatic and gastric lipase, which leads to the malabsorption of intestinal triglycerides and causes steatorrhoea.
Fenfluramine: Another misconception is that Fenfluramine causes systemic hypertension. It was actually banned due to its association with valvular heart disease and pulmonary hypertension.
Liposuction: Liposuction is not a weight loss method and should not be used as a substitute for diet and exercise. It is a cosmetic procedure that removes localized fat deposits.
Weight Loss: Weight loss is not a linear process and can vary from person to person. While glycogen depletion may contribute to initial weight loss, it is not the sole factor. Incremental weight loss occurs as adipose tissue is broken down.
Surgery: Restrictive surgery may be considered for morbidly obese patients under the age of 18, but this is not recommended as an initial option according to NICE guidelines.

A 50-year-old female complains of intermittent pain from her lower back to her groin and has visible blood in her urine. She is experiencing discomfort and cannot find a comfortable position. Upon examination, there are no indications of peritonitis. Which diagnostic test is most likely to be effective?
Your Answer: CT KUB
Explanation:Non-enhanced computed tomography scan of the kidneys, ureters, and bladder.
The management of renal stones involves initial medication and investigations, including an NSAID for analgesia and a non-contrast CT KUB for imaging. Stones less than 5mm may pass spontaneously, but more intensive treatment is needed for ureteric obstruction or renal abnormalities. Treatment options include shockwave lithotripsy, ureteroscopy, and percutaneous nephrolithotomy. Prevention strategies include high fluid intake, low animal protein and salt diet, and medication such as thiazides diuretics for hypercalciuria and allopurinol for uric acid stones.

A 32-year-old primip presents on day seven postpartum with unilateral breast pain. The pain started two days ago and is not accompanied by any other symptoms. She is struggling with breastfeeding and thinks her baby is not feeding long enough.
On examination, you notice an erythematosus, firm and swollen area, in a wedge-shaped distribution, on the right breast. The nipple appears normal.
Her observations are stable, and she is apyrexial.
Given the above, which of the following is the most likely diagnosis?Your Answer: Engorged breasts
Correct Answer: Mastitis
Explanation:Breast Conditions in Lactating Women
Lactating women may experience various breast conditions, including mastitis, breast abscess, cellulitis, engorged breasts, and full breasts.
Mastitis is typically caused by a blocked duct or ascending infection from nipple trauma during breastfeeding. Symptoms include unilateral pain, breast engorgement, and erythema. Treatment involves analgesia, reassurance, and continuing breastfeeding. Antibiotics may be necessary if symptoms persist or a milk culture is positive.
Breast abscess presents as a painful lump in the breast tissue, often with systemic symptoms such as fever and malaise. Immediate treatment is necessary to prevent septicaemia.
Cellulitis is an acute bacterial infection of the breast skin, presenting with erythema, tenderness, swelling, and blister formation. Non-specific symptoms such as rigors, fevers, and malaise may also occur.
Engorged breasts can be primary or secondary, causing bilateral breast pain and engorgement. The skin may appear shiny, and the nipple may appear flat due to stretching.
Full breasts are associated with lactation and cause warm, heavy, and hard breasts. This condition typically occurs between the 2nd and 6th day postpartum.

A 63-year-old man comes to the emergency department complaining of 'flutters in his chest' for the past 24 hours. He is aware of when his symptoms started and mentions having had 2 non-ST-elevation myocardial infarctions before. He has hypertension, which is controlled with perindopril monotherapy, and hypercholesterolaemia treated with atorvastatin. He has no other relevant medical history.
During the examination, the patient is alert and oriented. His blood pressure is 135/90 mmHg, heart rate is 112 beats per minute, temperature is 37.3ºC, and respiratory rate is 16 breaths per minute. An ECG shows an irregularly irregular rhythm. After discussing with the patient, a management plan is suggested.
What is the most likely management plan to be initiated for this patient based on his presentation?Your Answer: Begin anticoagulation, undergo immediate direct current (DC) cardioversion
Explanation:When a patient presents with new-onset atrial fibrillation (AF), the management plan depends on the duration and recurrence of symptoms, as well as risk stratification. If symptoms have been present for less than 48 hours, electrical cardioversion is recommended, but anticoagulation should be started beforehand. Heparin is a good choice for rapid onset anticoagulation. However, if symptoms have been present for more than 48 hours, there is a higher risk of atrial thrombus, which may cause thromboembolic disease. In this case, a transoesophageal echocardiogram (TOE) should be obtained to exclude a thrombus before cardioversion, or anticoagulation should be started for 3 weeks prior to cardioversion. Amiodarone oral therapy is not adequate for cardioversion in acute AF. If cardioversion is not possible, a DOAC such as apixaban or rivaroxaban should be started. Discharge home is appropriate for patients with chronic AF or after cardioversion. While pharmacological cardioversion with intravenous amiodarone is an option, electrical cardioversion is preferred according to NICE guidelines, especially in patients with structural heart disease.
Atrial Fibrillation and Cardioversion: Elective Procedure for Rhythm Control
Cardioversion is a medical procedure used in atrial fibrillation (AF) to restore the heart’s normal rhythm. There are two scenarios where cardioversion may be used: as an emergency if the patient is haemodynamically unstable, or as an elective procedure where a rhythm control strategy is preferred. In the elective scenario, cardioversion can be performed either electrically or pharmacologically. Electrical cardioversion is synchronised to the R wave to prevent delivery of a shock during the vulnerable period of cardiac repolarisation when ventricular fibrillation can be induced.
According to the 2014 NICE guidelines, rate or rhythm control should be offered if the onset of the arrhythmia is less than 48 hours, and rate control should be started if it is more than 48 hours or is uncertain. If the AF is definitely of less than 48 hours onset, patients should be heparinised and may be cardioverted using either electrical or pharmacological means. However, if the patient has been in AF for more than 48 hours, anticoagulation should be given for at least 3 weeks prior to cardioversion. An alternative strategy is to perform a transoesophageal echo (TOE) to exclude a left atrial appendage (LAA) thrombus. If excluded, patients may be heparinised and cardioverted immediately.
NICE recommends electrical cardioversion in this scenario, rather than pharmacological. If there is a high risk of cardioversion failure, it is recommended to have at least 4 weeks of amiodarone or sotalol prior to electrical cardioversion. Following electrical cardioversion, patients should be anticoagulated for at least 4 weeks. After this time, decisions about anticoagulation should be taken on an individual basis depending on the risk of recurrence.

A 36-year-old pregnant woman has a vaginal swab taken at 34 weeks gestation despite being asymptomatic. She informs you that during her previous pregnancy a bacteria which can cause sepsis in babies was detected on one of her swabs, which is why she needs to be tested again.
The microbiology report reads as follows:
Sample: Positive (awaiting sensitivities)
Gram stain: Positive
Morphology: Cocci in chains
Growth requirements: Facultative anaerobe
What is the most likely organism present based on this report?Your Answer: Streptococcus agalactiae
Explanation:Mothers who have previously tested positive for Group B Streptococcus during pregnancy should be given intravenous antibiotics as a preventative measure during labor or offered testing in late pregnancy and given antibiotics if the test is positive. Group B Streptococcus is a bacterium that can cause severe infections in newborns, including pneumonia and meningitis. It is a Gram-positive coccus that forms chains and is a facultative anaerobe. In contrast, Neisseria gonorrhoeae is a Gram-negative, diplococcus that requires oxygen to grow and is associated with conjunctivitis in newborns. Clostridium difficile is a Gram-positive, anaerobic bacillus that causes diarrheal illness, not neonatal sepsis.
Group B Streptococcus (GBS) is a common cause of severe infection in newborns. It is estimated that 20-40% of mothers carry GBS in their bowel flora, which can be passed on to their infants during labor and lead to serious infections. Prematurity, prolonged rupture of membranes, previous sibling GBS infection, and maternal pyrexia are all risk factors for GBS infection. The Royal College of Obstetricians and Gynaecologists (RCOG) has published guidelines on GBS management, which include not offering universal screening for GBS to all women and not offering screening based on maternal request. Women who have had GBS detected in a previous pregnancy should be offered intrapartum antibiotic prophylaxis (IAP) or testing in late pregnancy and antibiotics if still positive. IAP should also be offered to women with a previous baby with GBS disease, women in preterm labor, and women with a fever during labor. Benzylpenicillin is the preferred antibiotic for GBS prophylaxis.

A 28-year-old female patient arrives the day after ingesting an overdose of paracetamol. She appears to be dehydrated, and the house officer initiates an infusion while awaiting the results of her blood tests. What blood test result would indicate the need for liver transplantation referral?
Your Answer: Prothrombin time 60 seconds (12-16)
Correct Answer: Arterial lactate 3.6 mmol/L (0.2-1.8)
Explanation:Criteria for Liver Transplant Recommendation at King’s College Hospital
The King’s College Hospital Liver Transplant Unit has specific criteria for recommending a liver transplant. These criteria include an arterial pH of less than 7.3 or arterial lactate levels greater than 3.0 mmol/L after fluid rehydration. Additionally, if a patient experiences all three of the following conditions within a 24-hour period, a liver transplant may be recommended: PT levels greater than 100 seconds, creatinine levels greater than 300 µmol/L, and Grade III/IV encephalopathy.
It is important to note that mild elevations in creatinine levels may occur due to dehydration, and rises in transaminases may be seen as a result of hepatocellular damage. Therefore, these factors are not necessarily indicative of the need for a liver transplant. The specific criteria outlined by the King’s College Hospital Liver Transplant Unit are used to ensure that patients who truly require a liver transplant receive one in a timely manner.

A 28-year-old female patient presents to her GP complaining of cyclical pelvic pain and painful bowel movements. She has previously sought treatment from gynaecology and found relief with paracetamol and mefenamic acid, but the pain has returned and she is seeking alternative options. She is not pregnant but plans to start a family within the next few years. What would be the most appropriate next step in managing her condition from the options provided below?
Your Answer: Referral for laparoscopic excision or ablation
Correct Answer: Combined oral contraceptive pill
Explanation:If simple analgesia with paracetamol and NSAIDs is not effective in treating endometriosis symptoms, hormonal treatment with the combined oral contraceptive pill or a progesterone should be considered.
Although a referral to gynaecology may be necessary due to the recurrence of symptoms and potential pelvic/bowel involvement, primary care can offer further treatment options in the meantime. Hormonal treatment is recommended for this patient, and the combined oral contraceptive pill or any of the progesterone options can be used. As the patient plans to start a family soon, a hormonal option that can be quickly reversed is the most suitable.
Buscopan is not an appropriate treatment for endometriosis, as it only provides relief for menstrual cramps and is not a cure. It may be used to alleviate symptoms associated with irritable bowel syndrome.
Injectable depo-provera is not the best option for this patient, as it can delay the return of fertility, which conflicts with her desire to start a family within the next year.
Opioid analgesia is not recommended for endometriosis treatment, as it carries the risk of side effects and dependence. It is not a long-term solution for managing symptoms.
Understanding Endometriosis
Endometriosis is a common condition where endometrial tissue grows outside of the uterus. It affects around 10% of women of reproductive age and can cause chronic pelvic pain, painful periods, painful intercourse, and subfertility. Other symptoms may include urinary problems and painful bowel movements. Diagnosis is typically made through laparoscopy, and treatment options depend on the severity of symptoms.
First-line treatments for symptomatic relief include NSAIDs and/or paracetamol. If these do not help, hormonal treatments such as the combined oral contraceptive pill or progestogens may be tried. If symptoms persist or fertility is a priority, referral to secondary care may be necessary. Secondary treatments may include GnRH analogues or surgery. For women trying to conceive, laparoscopic excision or ablation of endometriosis plus adhesiolysis is recommended, as well as ovarian cystectomy for endometriomas.
It is important to note that there is poor correlation between laparoscopic findings and severity of symptoms, and that there is little role for investigation in primary care. If symptoms are significant, referral for a definitive diagnosis is recommended.

A patient with chronic kidney disease has a creatinine of 350 μmol/l and has persistent proteinuria.
Which one of the following drugs is most likely of benefit to his renal prognosis?Your Answer: Angiotensin converting enzyme (ACE) inhibitors
Explanation:Treatment Options for Proteinuria and Renal Prognosis
Proteinuria, the presence of excess protein in the urine, can be a sign of kidney damage or disease. Patients with proteinuria of any cause are at increased cardiovascular risk and require attention to modifiable risk factors such as smoking and hyperlipidemia. However, the renal prognosis can improve with the use of angiotensin converting enzyme (ACE) inhibitors, which are known to be effective in treating proteinuria. Aspirin and clopidogrel are not considered effective in improving renal outcomes for proteinuria. Blood pressure control is crucial in improving renal outcomes, and doxazosin may be useful in the right context. Methotrexate is not a recommended treatment option for proteinuria. Overall, ACE inhibitors remain the most effective treatment option for improving renal prognosis in patients with proteinuria.

Which nerve provides the motor supply to the brachialis muscle?
Your Answer: Median and musculocutaneous nerve
Correct Answer: Radial and musculocutaneous nerve
Explanation:The Brachialis Muscle: Anatomy and Innervation
The brachialis muscle is responsible for flexing the forearm and is located in the anterior half of the humerus and intermuscular septa. It attaches to the coronoid process and tuberosity of the ulna at the elbow joint. The main nerve supply for the brachialis muscle is the musculocutaneous nerve, with C6 and radial nerve also playing a role. Additionally, the lateral part of the brachialis muscle is supplied by branches from the C7 root. Overall, the brachialis muscle is an important muscle for forearm flexion and is innervated by multiple nerves.

A 10-year-old boy comes to his General Practitioner (GP) complaining of generalised itch for the past few days. He mentions that it is causing him to lose sleep at night. Upon examination, the GP observes linear burrows on the hands and evidence of excoriation on the abdomen and limbs. The GP suspects scabies as the underlying cause.
What is the initial treatment recommended for non-crusted scabies?Your Answer: Permethrin 5% cream
Explanation:Treatment Options for Scabies: Understanding the Role of Different Medications
Scabies is a skin condition caused by the Sarcoptes scabiei parasite. The primary treatment for non-crusted scabies is permethrin 5% cream, which is an insecticide. If permethrin is not tolerated or contraindicated, malathion can be used as a second-line agent. It is important to apply permethrin cream over the entire body and wash it off after 8-12 hours. Treatment should be repeated after one week.
Clotrimazole 2% cream, which is an antifungal medication, is not effective in treating scabies. Similarly, topical antibiotics like fusidic acid cream are not used to treat scabies unless there is a secondary bacterial infection.
Steroids like hydrocortisone 1% ointment are not used to treat scabies directly, but they can be used to alleviate symptoms like itching. Oral antibiotics like flucloxacillin are only necessary if there is a suspected secondary bacterial infection.
In summary, understanding the role of different medications in treating scabies is crucial for effective management of the condition.

A 68-year-old man presents with a three-month history of typical dyspepsia symptoms, including epigastric pain and a 2-stone weight loss. Despite treatment with a proton pump inhibitor, he has not experienced any relief. He now reports difficulty eating solids and frequent post-meal vomiting. On examination, a palpable mass is found in the epigastrium. His full blood count shows a haemoglobin level of 85 g/L (130-180). What is the probable diagnosis?
Your Answer: Carcinoma of stomach
Explanation:Alarm Symptoms of Foregut Malignancy
The presence of alarm symptoms in patients over 55 years old, such as weight loss, bleeding, dysphagia, vomiting, blood loss, and a mass, are indicative of a malignancy of the foregut. It is crucial to refer these patients for urgent endoscopy, especially if dysphagia is a new onset symptom. However, it is unfortunate that patients with alarm symptoms are often treated with PPIs instead of being referred for further evaluation. Although PPIs may provide temporary relief, they only delay the diagnosis of the underlying tumor.
The patient’s symptoms should not be ignored, and prompt referral for endoscopy is necessary to rule out malignancy. Early detection and treatment of foregut malignancy can significantly improve patient outcomes. Therefore, it is essential to recognize the alarm symptoms and refer patients for further evaluation promptly. Healthcare providers should avoid prescribing PPIs as a first-line treatment for patients with alarm symptoms and instead prioritize timely referral for endoscopy.

A 35-year-old female presents to the emergency department with persistent right upper quadrant pain and jaundiced sclera, three weeks after undergoing laparoscopic cholecystectomy. She is anxious about the possibility of a surgical complication requiring revision surgery.
What is the probable cause of her symptoms?Your Answer: Gallstones present in the common bile duct causing symptoms
Explanation:The correct answer to the multiple-choice question is CBD gallstones. While gallbladder stump gallstones can occur after laparoscopic cholecystectomies, they are less common than CBD gallstones. Additionally, it is important to note that the patient in the vignette is presenting 3 weeks after the operation, whereas gallbladder stump gallstones typically present over 9 months following incomplete gallbladder removal (although in rare cases, it can take up to 25 years postoperatively).
Biliary colic is a condition that occurs when gallstones pass through the biliary tree. The risk factors for this condition are commonly referred to as the ‘4 F’s’, which include being overweight, female, fertile, and over the age of forty. Other risk factors include diabetes, Crohn’s disease, rapid weight loss, and certain medications. Biliary colic occurs due to an increase in cholesterol, a decrease in bile salts, and biliary stasis. The pain associated with this condition is caused by the gallbladder contracting against a stone lodged in the cystic duct. Symptoms include right upper quadrant abdominal pain, nausea, and vomiting. Diagnosis is typically made through ultrasound. Elective laparoscopic cholecystectomy is the recommended treatment for biliary colic. However, around 15% of patients may have gallstones in the common bile duct at the time of surgery, which can result in obstructive jaundice. Other possible complications of gallstone-related disease include acute cholecystitis, ascending cholangitis, acute pancreatitis, gallstone ileus, and gallbladder cancer.

A 20-year-old man presents to his doctor with an enlarging neck mass. His mother had a right adrenal phaeochromocytoma which was successfully removed. The patient is 1.9m tall and weighs 74 kg. During examination, the doctor notices multiple yellowish white masses on the patient's lips and tongue. Three months later, the patient undergoes a total thyroidectomy. Which structure is innervated by the nerve most at risk during this procedure, and is also part of the vagus nerve?
Your Answer: Carotid sinus
Correct Answer: Aortic arch
Explanation:The aortic arch has baroreceptors that send afferent fibers to the vagus nerve. A patient with an enlarging neck mass, a family history of multiple endocrine neoplasia type 2B (MEN2B), and a marfanoid habitus may have medullary carcinoma of the thyroid, which is a feature of MEN2B. Surgery is the definitive treatment, but the recurrent laryngeal nerve, a branch of the vagus nerve, is at risk during thyroidectomy. The chorda tympani innervates the taste sensation to the anterior two-thirds of the tongue, while the lingual nerve and hypoglossal nerve innervate the general somatic sensation and motor function, respectively. The platysma muscle is innervated by cranial nerve VII, and the glossopharyngeal nerve (cranial nerve IX) carries general visceral afferent information from the carotid sinus to the brainstem. The spinal accessory nerve (cranial nerve XI) innervates both the sternocleidomastoid and trapezius muscles.

A 55-year-old male patient complains of pain in the right upper quadrant that has been bothering him for the past 5 hours. During examination, his blood pressure is 120/80 mmHg, heart rate is 75 bpm, temperature is 38.5ºC, and he displays signs of jaundice. What is the probable causative organism for this diagnosis?
Your Answer: E. coli
Explanation:Jaundice can present in various surgical situations, and liver function tests can help classify whether the jaundice is pre hepatic, hepatic, or post hepatic. Different diagnoses have typical features and pathogenesis, and ultrasound is the most commonly used first-line test. Relief of jaundice is important, even if surgery is planned, and management depends on the underlying cause. Patients with unrelieved jaundice have a higher risk of complications and death. Treatment options include stenting, surgery, and antibiotics.

A 51-year-old woman sustained a deep posterolateral laceration in her right neck during a car crash. Her right shoulder is now lower than the left and she is unable to lift it against resistance. When attempting to shrug her shoulders, there is no rise in muscle tone under the medial upper border of the right shoulder. Which nerve was affected by the injury?
Your Answer: Dorsal scapular nerve
Correct Answer: Spinal accessory nerve
Explanation:Nerves of the Shoulder: Functions and Injuries
The shoulder is a complex joint that relies on several nerves for proper function. Injuries to these nerves can result in a range of deficits, from isolated muscle weakness to more widespread impairments. Here are some of the key nerves involved in shoulder movement:
Spinal Accessory Nerve: This nerve innervates the sternocleidomastoid and trapezius muscles. Damage to the spinal accessory nerve can result in trapezius palsy, which can cause difficulty with shoulder elevation.
Dorsal Scapular Nerve: The dorsal scapular nerve innervates the rhomboid muscles and the levator scapulae. Injury to this nerve can lead to weakness in these muscles, which can affect shoulder blade movement.
Suprascapular Nerve: The suprascapular nerve innervates the supraspinatus muscle, which is part of the rotator cuff. Damage to this nerve can result in weakness or pain during shoulder abduction.
Axillary Nerve: The axillary nerve has both anterior and posterior branches that innervate the deltoid muscle and skin over part of the deltoid. Injury to this nerve can cause weakness or numbness in the shoulder.
Upper Trunk of the Brachial Plexus: The upper trunk of the brachial plexus is a collection of nerves that supply a wider variety of muscles and cutaneous structures. Damage to this area can result in more widespread deficits.
Understanding the functions and potential injuries of these nerves can help healthcare professionals diagnose and treat shoulder problems more effectively.

The blood film shows anisocytosis, poikilocytosis, and occasional erythrocyte tear drop cells. What is the correct term for this blood picture?Your Answer: Anaemia of chronic disease
Correct Answer: Leukoerythroblastic anaemia
Explanation:Leukoerythroblastic Reactions and Myelofibrosis
Leukoerythroblastic reactions refer to a condition where the peripheral blood contains immature white cells and nucleated red cells, regardless of the total white cell count. This means that even if the overall white cell count is normal, the presence of immature white cells and nucleated red cells can indicate a leukoerythroblastic reaction. Additionally, circulating blasts may also be seen in this condition.
On the other hand, myelofibrosis is characterized by the presence of tear drop cells. These cells are not typically seen in other conditions and are therefore considered a hallmark of myelofibrosis. Tear drop cells are red blood cells that have been distorted due to the presence of fibrous tissue in the bone marrow. This condition can lead to anemia, fatigue, and other symptoms.
Overall, both leukoerythroblastic reactions and myelofibrosis are conditions that can be identified through specific characteristics in the peripheral blood. It is important for healthcare professionals to be aware of these findings in order to properly diagnose and treat patients.

A 56-year-old woman has been prescribed metformin for her type II diabetes and wants to know about potential side effects. What is the most common adverse effect associated with metformin treatment?
Your Answer: Rhabdomyolysis
Correct Answer: Lactic acidosis
Explanation:Potential Adverse Effects of Diabetes Medications
Diabetes medications can be effective in managing blood sugar levels, but they also come with potential adverse effects. One such effect is lactic acidosis, which can be severe or even fatal in cases of intentional metformin overdose. Metformin works by inhibiting hepatic gluconeogenesis and lactate dehydrogenase in the gut and liver. In cases of lactic acidosis, haemodialysis may be necessary to clear lactate and correct acidosis, but mortality rates remain high due to coexisting organ failures.
Another potential adverse effect is cardiotoxicity, which can lead to fluid retention and cardiac failure in patients receiving glitazone therapy. However, anaphylaxis and pulmonary fibrosis are not recognised features of metformin therapy. Rhabdomyolysis, a breakdown of muscle tissue, is more likely to occur in conjunction with statin or fibrate therapy, or with the combination of the two.
