  1. A hemodynamically stable patient has atrial fibrillation with rapid ventricular response (HR 148 bpm) and preserved ejection fraction. Which drug is preferred for acute rate control?

    Answer: Metoprolol 5mg IV over 2 minutes (may repeat x2)

    IV beta-blockers such as metoprolol are first-line for rate control in AF with RVR in hemodynamically stable patients with preserved EF.

  2. A patient presents 2.5 hours after ischemic stroke onset with NIHSS 12 and BP 160/88 mmHg. There are no contraindications. What is the correct treatment and dose?

    Answer: Alteplase (tPA) 0.9mg/kg IV (max 90mg), 10% as bolus then remainder over 60 min

    Alteplase 0.9mg/kg IV (max 90mg) is the standard thrombolytic for eligible ischemic stroke within 4.5 hours of onset.

  3. A patient with Type 1 diabetes presents in DKA (glucose 520 mg/dL, pH 7.08, bicarbonate 8 mEq/L). What is the initial fluid resuscitation of choice?

    Answer: 0.9% Normal saline 1L IV over 1 hour

    Isotonic normal saline is the initial fluid for DKA to correct volume deficit and hemodynamic instability before transitioning to 0.45% NaCl.

  4. An unconscious patient is found with pinpoint pupils and a respiratory rate of 4 breaths/min. What is the immediate treatment?

    Answer: Naloxone 0.4–2mg IV/IM/intranasal

    Naloxone is the specific opioid antagonist that rapidly reverses opioid-induced respiratory depression, miosis, and coma.

  5. A patient in cardiac arrest with ventricular fibrillation has received CPR and two defibrillation shocks without return of spontaneous circulation. What drug is indicated next?

    Answer: Epinephrine 1mg IV every 3–5 minutes

    Epinephrine 1mg IV every 3–5 minutes is the vasopressor of choice in cardiac arrest per current ACLS guidelines.

  6. A diabetic patient is found unconscious with a blood glucose of 28 mg/dL. IV access is established. What is the appropriate treatment?

    Answer: Dextrose 50% (D50W) 25g IV push

    IV dextrose 50% (D50W) 25–50g provides the fastest correction of severe hypoglycemia when IV access is available.

  7. A patient has a massive pulmonary embolism confirmed by CT-PA with BP 78/48 mmHg and HR 128 bpm. What is the definitive treatment?

    Answer: Systemic thrombolysis with alteplase 100mg IV over 2 hours

    Systemic thrombolysis with alteplase 100mg over 2 hours is the treatment for massive PE with hemodynamic compromise.
