  1. A patient with HIV on antiretroviral therapy has a CD4 count of 150 cells/μL. Which opportunistic infection prophylaxis is MOST indicated?

    Answer: Trimethoprim-sulfamethoxazole for Pneumocystis jirovecii pneumonia

    TMP-SMX prophylaxis for PCP is indicated when CD4 count falls below 200 cells/μL.

  2. Which hepatitis B vaccine schedule is recommended for adults with diabetes mellitus aged 60 years or older?

    Answer: Vaccination should be at the clinician's discretion based on risk

    ACIP recommends hepatitis B vaccination for adults 19–59 with diabetes and at the clinician's discretion for those ≥60 years.

  3. A patient is prescribed rifampin for latent TB. Which drug interaction requires the most urgent counseling?

    Answer: Warfarin — reduced anticoagulant effect

    Rifampin is a potent CYP450 inducer that significantly reduces warfarin levels, increasing thromboembolism risk.

  4. Which statement best describes the role of oseltamivir in outpatient influenza management?

    Answer: Most beneficial when initiated within 48 hours of symptom onset

    Oseltamivir reduces duration and severity of influenza most effectively when started within 48 hours of symptom onset.

  5. A 35-year-old pregnant woman at 28 weeks asks about Tdap vaccination. What is the correct guidance?

    Answer: Administer Tdap during each pregnancy, preferably between 27–36 weeks gestation

    ACIP recommends Tdap during every pregnancy, ideally at 27–36 weeks, to provide neonatal pertussis protection via maternal antibody transfer.

  6. A patient with recurrent UTIs requests prophylaxis. Which regimen is evidence-based for continuous antibiotic prophylaxis?

    Answer: Nitrofurantoin 50–100 mg daily at bedtime

    Nitrofurantoin at low doses taken nightly is a well-established option for continuous prophylaxis of recurrent uncomplicated UTIs.

  7. Which vaccine is CONTRAINDICATED in a patient receiving high-dose corticosteroids (prednisone ≥20 mg/day for >2 weeks)?

    Answer: Live attenuated influenza vaccine (LAIV)

    LAIV is a live vaccine contraindicated in immunocompromised patients, including those on high-dose systemic corticosteroids.
