,Q1. A 45-year-old executive presents with sudden severe headache described as 'worst
of my life,' but neurological exam is normal. Non-contrast CT head is negative. What
is the most appropriate next step?
A. Lumbar puncture for xanthochromia
B. MRI with MR angiography
C. Reassure and prescribe migraine abortive
D. CT angiography of the head
Correct Answer: A. Lumbar puncture for xanthochromia
Rationale: A negative non-contrast CT within 6 hours does not exclude subarachnoid
hemorrhage (SAH). Lumbar puncture for xanthochromia remains the gold standard to rule
out SAH if CT is negative, as it detects blood breakdown products. MRI/MRA may miss
small SAH, and CTA is not the first-line confirmatory test after a negative CT.
Why Wrong:
B - MRI/MRA is less sensitive for acute SAH than LP and not the next step.
C - Reassurance is dangerous given the concern for SAH.
D - CTA is useful for aneurysms but does not confirm SAH as reliably as LP.

Emergency Medicine, 10th ed.
Q2. A patient on chronic loop diuretic therapy develops a new arrhythmia. ECG
shows U waves and QT prolongation. Which electrolyte abnormality is most likely to
cause this?
A. Hypercalcemia
B. Hypokalemia
C. Hypermagnesemia
D. Hypernatremia
Correct Answer: B. Hypokalemia
Rationale: Loop diuretics cause hypokalemia, which leads to U waves, QT prolongation,
and arrhythmias. Hypokalemia increases automaticity and delayed repolarization.
Hypercalcemia shortens QT, hypermagnesemia causes bradycardia, and hypernatremia
does not cause U waves.
Why Wrong:
A - Hypercalcemia shortens QT interval, not prolongs.
C - Hypermagnesemia typically causes bradycardia and AV block.
D - Hypernatremia does not produce U waves or QT changes.

, Q3. Which of the following best explains the mechanism of action of metformin in
type 2 diabetes?
A. Increases insulin secretion from pancreatic beta cells
B. Activates PPAR-gamma receptors in adipose tissue
C. Reduces hepatic glucose production and improves insulin sensitivity
D. Blocks SGLT2 in the proximal tubule to increase glucosuria
Correct Answer: C. Reduces hepatic glucose production and improves insulin
sensitivity
Rationale: Metformin primarily suppresses hepatic gluconeogenesis and enhances
peripheral insulin sensitivity, without increasing insulin secretion. Sulfonylureas stimulate
insulin release, thiazolidinediones activate PPAR-gamma, and SGLT2 inhibitors block
renal glucose reabsorption.
Why Wrong:
A - This describes sulfonylureas or meglitinides.
B - This describes thiazolidinediones like pioglitazone.
D - This describes SGLT2 inhibitors like empagliflozin.
Reference: Lehne, Pharmacology for Nursing Care, 12th ed., Ch. 45
Q4. A patient presents with sudden onset of severe left-sided chest pain radiating to
the back, and blood pressure difference of 30 mmHg between arms. What is the most
likely diagnosis?
A. Acute myocardial infarction
B. Pulmonary embolism
C. Aortic dissection
D. Pericarditis
Correct Answer: C. Aortic dissection
Rationale: Aortic dissection presents with sudden severe chest/back pain and can cause
pulse or blood pressure differentials between arms due to malperfusion. MI, PE, and
pericarditis do not typically cause inter-arm BP differences.
Why Wrong:
A - MI usually does not cause inter-arm BP discrepancy.
B - PE presents with dyspnea, pleuritic pain, and hypoxia.
D - Pericarditis is pleuritic and positional, no pulse deficits.

Q5. Which of the following is the most appropriate first-line treatment for a patient
with newly diagnosed major depressive disorder and comorbid insomnia?
A. Fluoxetine
