  1. A patient with heart failure (EF 35%) is started on carvedilol. Which clinical response would indicate the drug should be titrated up sooner than planned?

    Answer: Patient reports improved dyspnea on exertion at 2 weeks

    Symptomatic improvement such as reduced dyspnea indicates the patient is tolerating beta-blockade well and supports dose uptitration.

  2. Which therapeutic drug monitoring parameter is MOST clinically relevant for vancomycin in treating MRSA bacteremia?

    Answer: AUC24/MIC ratio of 400-600 mg·h/L

    Current ASHP/IDSA/SIDP guidelines recommend AUC24/MIC-guided vancomycin dosing (400-600) over trough-only monitoring for MRSA infections.

  3. A patient's tacrolimus trough is 3.2 ng/mL at 6 months post-kidney transplant (target 5-10 ng/mL). After ruling out non-adherence, what is the most likely cause of subtherapeutic levels?

    Answer: Recent initiation of rifampin

    Rifampin is a potent CYP3A4 and P-glycoprotein inducer that can reduce tacrolimus levels by up to 90%, leading to rejection risk.

  4. In a patient with stage 4 CKD (eGFR 22 mL/min/1.73m²) and type 2 diabetes, which glucose-lowering agent requires the most significant dose adjustment?

    Answer: Metformin

    Metformin is contraindicated when eGFR falls below 30 mL/min/1.73m² due to risk of lactic acidosis from drug accumulation.

  5. Which monitoring frequency is appropriate for patients on long-term oral corticosteroids to screen for a common metabolic complication?

    Answer: Fasting glucose at baseline and every 3 months

    Corticosteroids cause gluconeogenesis and insulin resistance, making quarterly fasting glucose monitoring essential to detect steroid-induced hyperglycemia.

  6. A patient on phenytoin for epilepsy has a total phenytoin level of 8 mcg/mL with albumin of 2.1 g/dL. What does this result indicate?

    Answer: Likely therapeutic free phenytoin level despite low total

    Using the Sheiner-Tozer equation, corrected phenytoin = 8/(0.2×2.1 + 0.1) ≈ 16 mcg/mL, suggesting adequate free drug levels despite low albumin.

  7. When assessing adherence in a patient with poorly controlled hypertension, which objective measure provides the most reliable verification?

    Answer: Pharmacy refill records over 6 months

    Pharmacy refill records (medication possession ratio) provide an objective, longitudinal measure of adherence that is less subject to white-coat bias than clinic-based assessments.
