Question 1
Correct
-
A 77-year-old female who is a known to have COPD and metastatic lung cancer is admitted with increasing shortness of breath. Following discussion with her family, it is decided to withdraw active treatment including fluids and antibiotics as the admission likely represents a terminal event. Two days after admission, she becomes agitated and restless. What is the most appropriate management for her agitation and confusion?
Your Answer: Subcutaneous midazolam
Explanation:Generally, underlying causes of confusion need to be looked for and treated as appropriate, for example, hypercalcaemia, infection, urinary retention, and medication. If specific treatments fail, the following may be tried:
1. First choice: haloperidol
2. Other options: chlorpromazine, levomepromazineIn the terminal phase of the illness, agitation or restlessness is best treated with midazolam.

A 71-year-old woman with a medical history of a blood transfusion in the early 1980s presents with a 10 month history of malaise and is noted to have impaired renal function. Her urine sediment reveals red cell casts. The results of immunological investigations are as follows: serum IgG 6.5 g/L (normal range 6-13), IgA 1.5 g/L (normal range 0.8-4.0), IgM 5.7 g/L (normal range 0.4-2.0), serum electrophoresis shows a faint band in the gamma region, complement C3 1.02 g/L (normal range 0.75-1.65), complement C4 <0.02 g/L (normal range 0.20-0.65), and rheumatoid factor 894 IU/L (normal range <40). Which of the following investigations is likely to be most important in making a definitive diagnosis?
Your Answer: Antineutrophil cytoplasmic antibodies
Correct Answer: Cryoglobulins
Explanation:The patient’s history of a blood transfusion and lab results showing a markedly low C4 (with normal C3), elevated rheumatoid factor, and elevated serum IgM is highly suggestive of hepatitis C-associated cryoglobulinaemic vasculitis. Testing for Cryoglobulins will confirm this suspicion.

A 50 yr. old male presented with acute severe central chest pain and acute ST elevation myocardial infarction was diagnosed. He was treated with streptokinase. 2 days later he was sweating excessively and he was found to be hypotensive. Which of the following cannot be considered as a reason for this presentation?
Your Answer: Hypotensive effect of streptokinase
Explanation:Hypotensive effect of streptokinase occurs during the streptokinase infusion which is usually transient. Acute mitral regurgitation due to rupture of papillary muscles, ventricular septal defects and reinfarctions (left or right) are known to cause hypotension after 24 hrs. Pulmonary embolism is less likely but cannot be excluded.

A 44-year-old woman is investigated for hot flushes and night sweats. Her blood tests show a significantly raised FSH level and her symptoms are attributed to menopause. Following discussions with the patient, she elects to have hormone replacement treatment. What is the most significant risk of prescribing an oestrogen-only preparation rather than a combined oestrogen-progestogen preparation?
Your Answer: Increased risk of venous thromboembolism
Correct Answer: Increased risk of endometrial cancer
Explanation:The use of hormone replacement therapy (HRT) based on unopposed oestrogen increases the risk of endometrial cancer, and uterine hyperplasia or cancer.
Evidence from randomized controlled studies showed a definite association between HRT and uterine hyperplasia and cancer. HRT based on unopposed oestrogen is associated with this observed risk, which is unlike the increased risk of breast cancer linked with combined rather than unopposed HRT. -

A 48-year-old man is diagnosed with acute myeloid leukaemia. Cytogenetic testing is carried out. Which one of the following is mostly associated with a poor prognosis?
Your Answer: Translocation between chromosome 15 and 17
Correct Answer: Deletions of chromosome 5
Explanation:Deletion of part of chromosome 5 or 7 is a poor prognostic feature for acute myeloid leukaemia (AML).
AML is the acute expansion of the myeloid stem line, which may occur as a primary disease or follow the secondary transformation of a myeloproliferative disorder. It is more common over the age of 45 and is characterized by signs and symptoms largely related to bone marrow failure such as anaemia (pallor, lethargy), frequent infections due to neutropenia (although the total leucocyte count may be very high), thrombocytopaenia (bleeding), ostealgia, and splenomegaly.
The disease has poor prognosis if:
1. Age of the patient >60 years
2. >20% blasts seen after the first course of chemotherapy
3. Chromosomal aberration with deletion of part of chromosome 5 or 7.Acute promyelocytic leukaemia (APL) is an aggressive form of AML.

A 48-year-old patient with diabetes is referred from the Emergency department complaining of dizziness and vomiting. On examination he is alert and orientated, his pulse is 80 irregularly irregular and BP 160/90 mmHg. There is nystagmus on left lateral gaze and his speech is slurred. On examination of the limbs, you note intention tremor and past pointing. He is ataxic when mobilised. What is the likely diagnosis?
Your Answer:
Correct Answer: Cerebellar CVA
Explanation:The patient’s presentation with slurred speech, intention tremor and past pointing, as well as ataxia and nystagmus, paired with a history of vertigo suggest the cerebellum as the site of cerebrovascular accident (CVA) or stroke.

A 63 year old man with known allergic bronchopulmonary aspergillosis presents to the A&E Department with an exacerbation. Which therapy represents the most appropriate management?
Your Answer:
Correct Answer: Oral glucocorticoids
Explanation:Allergic bronchopulmonary aspergillosis (ABPA) is a form of lung disease that occurs in some people who are allergic to Aspergillus. With ABPA, this allergic reaction causes the immune system to overreact to Aspergillus leading to lung inflammation. ABPA causes bronchospasm (tightening of airway muscles) and mucus build-up resulting in coughing, breathing difficulty and airway obstruction.
Treatment of ABPA aims to control inflammation and prevent further injury to your lungs. ABPA is a hypersensitivity reaction that requires treatment with oral corticosteroids. Inhaled steroids are not effective. ABPA is usually treated with a combination of oral corticosteroids and anti-fungal medications. The corticosteroid is used to treat inflammation and blocks the allergic reaction. Examples
of corticosteroids include: prednisone, prednisolone or methylprednisolone. Inhaled corticosteroids alone – such as used for asthma treatment – are not effective in treating ABPA. Usually treatment with an oral corticosteroid is needed for months.The second type of therapy used is an anti-fungal medication, like itraconazole and voriconazole. These medicines help kill Aspergillus so that it no longer colonizes the airway. Usually one of these drugs is given for at least 3 to 6 months. However, even this treatment is not curative and can have side effects.

A 27-year-old man with a history of asthma presents for review. He has recently been discharged from hospital following an acute exacerbation and reports generally poor control with a persistent night time cough and exertional wheeze. His current asthma therapy is: salbutamol inhaler 100mcg prn Clenil (beclomethasone dipropionate) inhaler 800mcg bd salmeterol 50mcg bd He has a history of missing appointments and requests a prescription with as few side-effects as possible. What is the most appropriate next step in management?
Your Answer:
Correct Answer: Leukotriene receptor antagonist
Explanation:The NICE 2019 guidelines states that in patients who are uncontrolled with a SABA (Salbutamol) and ICS (Beclomethasone), LTRA should be added.
If asthma is uncontrolled in adults (aged 17 and over) on a low dose of ICS as maintenance therapy, offer a leukotriene receptor antagonist (LTRA) in addition to the ICS and review the response to treatment in 4 to 8 weeks. -

A 40-year-old female is receiving a course of chemotherapy for breast cancer. She is, however, experiencing troublesome vomiting which is not responding to domperidone. Which of the following is the most appropriate next step of management?
Your Answer:
Correct Answer: Add a 5-HT3 antagonist
Explanation:Nausea and vomiting are the common side effects of chemotherapy. Risk factors for the development of these symptoms include age<50 years, anxiety, concurrent use of opioids, and the type of chemotherapy administered. For patients at low risk of these symptoms, drugs such as metoclopramide may be used. For high-risk patients, however, 5-HT3 receptor antagonists such as ondansetron are often effective, especially if combined with dexamethasone.

Which one of the following statements is incorrect with regards to post-partum mental health problems?
Your Answer:
Correct Answer: Post-natal depression is seen in around 2-3% of women
Explanation:Most new moms experience postpartum baby blues after childbirth, which commonly include mood swings, crying spells, anxiety and difficulty sleeping. Baby blues typically begin within the first two to three days after delivery, and may last for up to two weeks.
Postpartum depression may be mistaken for baby blues at first — but the signs and symptoms are more intense and last longer, and may eventually interfere with your ability to care for your baby and handle other daily tasks. Symptoms usually develop within the first few weeks after giving birth, but may begin earlier, during pregnancy or later, up to a year after birth.
The period prevalence of postpartum depression among women is a striking 21.9% the first year after birth, which makes it one of the most common medical complications of childbearing. Sertraline has been identified as an antidepressant of choice for breastfeeding women because infants are unlikely to develop quantifiable serum sertraline levels and very few adverse events associated with sertraline have been reported.
Women with a prior episode of postpartum psychosis have about a 30% risk of having another episode in the next pregnancy.
