  1. Which vaccine is contraindicated in a severely immunocompromised patient?

    Answer: Live attenuated zoster (Zostavax)

    Live vaccines like the older zoster vaccine are contraindicated in severe immunosuppression.

  2. A patient on lithium starts an NSAID. What is the expected effect?

    Answer: Increased lithium levels

    NSAIDs reduce renal lithium clearance, raising serum lithium and toxicity risk.

  3. Which electrolyte abnormality predisposes to digoxin toxicity?

    Answer: Hypokalemia

    Hypokalemia increases digoxin binding to Na/K-ATPase, enhancing toxicity.

  4. What is the preferred treatment for a pregnant patient with a UTI in the first trimester?

    Answer: Cephalexin

    Cephalexin is a safe first-line choice; nitrofurantoin and sulfa are avoided near term, and fluoroquinolones/tetracyclines are contraindicated.

  5. Which monitoring parameter is most important for a patient starting amiodarone long term?

    Answer: Thyroid and pulmonary function

    Amiodarone can cause thyroid dysfunction and pulmonary fibrosis, requiring baseline and periodic monitoring.

  6. A patient taking an SSRI is started on tramadol. What is the primary concern?

    Answer: Serotonin syndrome

    Tramadol has serotonergic activity, and combining it with an SSRI raises serotonin syndrome risk.

  7. Which agent is first-line for acute anaphylaxis?

    Answer: IM epinephrine

    Intramuscular epinephrine into the anterolateral thigh is the immediate first-line treatment for anaphylaxis.
