  1. A patient develops signs of serotonin syndrome after being prescribed linezolid while already on sertraline. Which symptom BEST distinguishes serotonin syndrome from neuroleptic malignant syndrome?

    Answer: Hyperreflexia and clonus

    Hyperreflexia and clonus are hallmark features of serotonin syndrome and are generally absent in neuroleptic malignant syndrome, which features lead-pipe rigidity instead.

  2. Which class of antihypertensives is CONTRAINDICATED in bilateral renal artery stenosis?

    Answer: ACE inhibitors

    ACE inhibitors (and ARBs) block angiotensin II-mediated efferent arteriolar constriction, which is the compensatory mechanism maintaining GFR in bilateral renal artery stenosis, leading to acute kidney injury.

  3. A drug has a half-life of 8 hours. How long will it take to reach approximately 94% of steady-state concentration with regular dosing?

    Answer: 32 hours

    It takes approximately 4 half-lives to reach ~94% of steady state; 4 × 8 hours = 32 hours.

  4. Which antiepileptic drug works primarily by blocking voltage-gated sodium channels and is first-line for focal seizures?

    Answer: Carbamazepine

    Carbamazepine blocks voltage-gated sodium channels, stabilizing neuronal membranes, and is a first-line agent for focal (partial) seizures.

  5. A compounding pharmacist needs to prepare an isotonic solution. What is the approximate freezing point depression of normal saline (0.9% NaCl)?

    Answer: -0.52°C

    Normal saline (0.9% NaCl) has a freezing point depression of -0.52°C, which equals the freezing point depression of blood, making it isotonic.

  6. Which metabolic pathway is PRIMARILY responsible for phase II conjugation of acetaminophen under normal dosing conditions?

    Answer: Glucuronidation and sulfation

    Under therapeutic doses, acetaminophen is primarily metabolized by glucuronidation (~55%) and sulfation (~30%); CYP2E1-mediated oxidation to NAPQI becomes significant only in overdose when conjugation pathways are saturated.

  7. What is the primary mechanism by which aminoglycosides cause nephrotoxicity?

    Answer: Accumulation in proximal tubular cells causing cellular damage

    Aminoglycosides accumulate in proximal tubular epithelial cells through endocytosis, causing mitochondrial dysfunction, oxidative stress, and tubular necrosis.
