1. A 62-year-old man presents with fatigue and pruritus. His alkaline
phosphatase is elevated far more than AST/ALT. What is the most
likely diagnosis?
Answer: Cholestatic liver disease
Rationale: Markedly elevated alkaline phosphatase relative to
AST/ALT suggests cholestasis (e.g., primary biliary cholangitis,
obstruction), not hepatocellular injury.
2. A patient with COPD develops worsening dyspnea and confusion. His
PaCO₂ is high and pH is low. What is occurring?
Answer: Acute on chronic respiratory acidosis
Rationale: Elevated PaCO₂ with acidemia in COPD indicates acute
worsening of chronic CO₂ retention.
3. A 25-year-old with new diabetes has polyuria and thirst. Blood glucose
is 410 mg/dL, no ketones. What best describes this?
Answer: Hyperosmolar hyperglycemic state (HHS)
Rationale: Very high glucose without significant ketosis suggests HHS
rather than DKA.
4. A patient on an SSRI develops agitation, tremor, and hyperreflexia
after starting tramadol. What is the likely cause?
, Answer: Serotonin syndrome
Rationale: SSRIs + tramadol increase serotonin risk, causing
neuromuscular hyperactivity and altered mental status.
5. A 70-year-old with asthma uses albuterol frequently with minimal
relief. Next step?
Answer: Add an inhaled corticosteroid
Rationale: Persistent symptoms despite rescue inhaler necessitate
anti-inflammatory treatment.
6. A child presents with fever, drooling, and leaning forward. He is in
distress. Most concerning diagnosis?
Answer: Epiglottitis
Rationale: Fever, drooling, and “tripod” position indicate airway
obstruction requiring urgent care.
7. A hypertensive patient started on hydrochlorothiazide reports muscle
cramps and weakness. Which electrolyte is likely low?
Answer: Potassium
Rationale: Thiazide diuretics cause increased renal potassium loss
leading to hypokalemia.
8. A patient with atrial fibrillation is started on warfarin. What lab is
monitored to assess anticoagulation?
Answer: INR
Rationale: INR measures warfarin effect on clotting and guides dose
adjustments.
,9. A pregnant woman at 36 weeks presents with headache and visual
disturbances. Blood pressure is 170/110. Likely condition?
Answer: Preeclampsia with severe features
Rationale: Severe hypertension and neurologic symptoms after 20
weeks suggest preeclampsia.
10. A young adult with sudden sharp chest pain that worsens with
inspiration and decreased breath sounds on one side likely has:
Answer: Pneumothorax
Rationale: Pleuritic chest pain and unilateral diminished breath sounds
suggest lung collapse.
11. A diabetic patient with poor glycemic control has a fasting
glucose of 160 mg/dL and HbA1c of 9%. What is primary goal of
management?
Answer: Improve glycemic control (target HbA1c <7%)
Rationale: Lower HbA1c reduces long-term complications of diabetes.
12. A patient taking lisinopril develops a dry, persistent cough. What
is the cause?
Answer: Increased bradykinin
Rationale: ACE inhibitors increase bradykinin, causing cough in some
patients.
13. A 50-year-old with sudden severe headache described as “worst
ever” needs immediate evaluation for:
Answer: Subarachnoid hemorrhage
Rationale: Thunderclap headache requires urgent imaging to rule out
bleed.
, 14. A patient with heart failure presents with weight gain, edema, and
dyspnea. Best initial therapy adjustment?
Answer: Increase loop diuretic
Rationale: Fluid overload in HF improves with diuresis.
15. A patient with bacterial pneumonia is started on antibiotics but
develops a rash after 48 hours. Likely cause?
Answer: Drug reaction
Rationale: New rash after antibiotic exposure typically indicates
hypersensitivity.
16. A 30-year-old presents with sudden palpitations and HR of 180
bpm. ECG shows narrow QRS tachycardia. Next step?
Answer: Vagal maneuvers
Rationale: SVT with narrow QRS often responds to vagal maneuvers
before drugs.
17. A patient with chronic renal failure has elevated phosphorus and
low calcium. What hormone is likely elevated?
Answer: Parathyroid hormone
Rationale: Secondary hyperparathyroidism occurs due to
hypocalcemia and hyperphosphatemia.
18. A child with sore throat, fever, and white tonsillar exudate should
be tested for:
Answer: Group A Streptococcus
Rationale: Rapid strep testing confirms bacterial pharyngitis needing
antibiotics.
