Q1 Question 1 of 75
A 68-year-old man arrives in the emergency department with severe substernal chest pressure radiating to
his left arm, diaphoresis, and dyspnea that began 45 minutes ago. The 12-lead ECG shows ST-segment
elevation in leads II, III, and aVF with reciprocal depression in I and aVL. What is the most appropriate
immediate intervention?
A. Administer aspirin, initiate dual antiplatelet therapy, and activate the catheterization laboratory for
primary PCI
B. Administer sublingual nitroglycerin alone and observe for 30 minutes before further treatment
C. Start a heparin infusion and delay reperfusion until troponin results return
D. Administer metoprolol intravenously immediately and withhold reperfusion
Correct Answer: A
Rationale:
ST-elevation in the inferior leads with reciprocal changes indicates an acute STEMI requiring immediate
reperfusion via primary PCI within 90 minutes or fibrinolytics if PCI is unavailable. Nitroglycerin alone, waiting
for troponins, or immediate beta-blockade before reperfusion would delay the time-critical restoration of
coronary blood flow.
Q2 Question 2 of 75
A 72-year-old woman with a history of hypertension presents with sudden-onset tearing chest pain
radiating to her back, blood pressure of 180/110 mmHg in the right arm and 140/85 mmHg in the left arm,
and a widened mediastinum on chest x-ray. What is the priority pharmacologic intervention?
A. Intravenous nitroglycerin as a single agent to lower blood pressure rapidly
B. Intravenous labetalol to control heart rate and blood pressure before surgical evaluation
C. Intravenous morphine only for pain control without blood pressure management
D. Oral losartan and outpatient follow-up imaging in one week
Correct Answer: B
Rationale:
Suspected acute aortic dissection requires immediate IV beta-blocker therapy to reduce shear stress on the
aorta by lowering heart rate and blood pressure before surgical or endovascular repair. Nitroglycerin alone
causes reflex tachycardia that increases aortic shear force, morphine alone fails to address the lethal
hemodynamic driver, and outpatient management would be unsafe in an acute dissection.
, Q3 Question 3 of 75
A 55-year-old man with no prior cardiac history presents with new-onset crushing chest pain, and his ECG
shows a left bundle branch block that is known to be new since an ECG six months ago. Cardiac troponin
is elevated. What is the correct interpretation of this presentation?
A. Discharge home with a Holter monitor since bundle branch block is benign
B. Administer a calcium channel blocker and observe on a telemetry floor
C. Treat as a STEMI equivalent and activate the catheterization laboratory for emergent reperfusion
D. Treat as unstable angina and defer imaging until symptoms completely resolve
Correct Answer: C
Rationale:
A new or presumed-new left bundle branch block in the setting of ischemic symptoms and elevated troponins
is a STEMI equivalent requiring emergent reperfusion therapy. The other options fail to recognize the
high-risk nature of a new conduction abnormality with myocardial injury and would dangerously delay
definitive treatment.
Q4 Question 4 of 75
A 60-year-old woman with acute decompensated heart failure has crackles throughout both lung fields, an
S3 gallop, blood pressure 88/55 mmHg, and a respiratory rate of 32. Which vasoactive therapy is most
appropriate given her hypotension with pulmonary congestion?
A. Intravenous nitroprusside to rapidly reduce afterload as monotherapy
B. Intravenous metoprolol to control tachycardia and reduce myocardial oxygen demand
C. Sublingual nitroglycerin to relieve preload without addressing hypotension
D. Intravenous norepinephrine to improve perfusion while diuresis is initiated
Correct Answer: D
Rationale:
In cardiogenic shock with pulmonary edema, norepinephrine provides vasoconstrictive inotropic support to
maintain perfusion while diuresis is initiated, since pure vasodilators would worsen hypotension. Nitroprusside
alone would precipitate cardiovascular collapse, beta-blockers are contraindicated in acute decompensation
with hypotension, and sublingual nitroglycerin alone fails to address the hypotensive state.
, Q5 Question 5 of 75
A 78-year-old man on warfarin for atrial fibrillation presents with an INR of 9.5 and an acute intracranial
hemorrhage seen on CT. Which reversal strategy is most appropriate as the first-line intervention?
A. Administer four-factor prothrombin complex concentrate plus intravenous vitamin K
B. Administer fresh frozen plasma alone and recheck the INR in 12 hours
C. Administer intravenous vitamin K alone and observe for neurologic changes
D. Withhold warfarin and monitor the INR without reversal agents
Correct Answer: A
Rationale:
Life-threatening warfarin-associated intracranial hemorrhage requires immediate reversal with four-factor
prothrombin complex concentrate for rapid factor replacement plus vitamin K for sustained reversal. Fresh
frozen plasma alone is slower and requires larger volumes, vitamin K alone works too slowly for an acute
bleed, and withholding warfarin without reversal fails to address the immediate hemorrhage risk.
Q6 Question 6 of 75
A 45-year-old woman with asthma presents with severe respiratory distress, unable to speak in full
sentences, with silent chest and an SpO2 of 88% on room air. She has used her albuterol inhaler four
times without relief. What is the most appropriate immediate pharmacologic addition?
A. Intravenous benzodiazepines to reduce anxiety-driven hyperventilation
B. Nebulized albuterol with ipratropium plus intravenous corticosteroids and magnesium
C. Continuous nebulized formoterol alone without corticosteroids
D. Subcutaneous epinephrine followed by discharge on antihistamines
Correct Answer: B
Rationale:
Severe acute asthma with a silent chest requires combined nebulized bronchodilators, systemic
corticosteroids to address inflammation, and IV magnesium for its bronchodilatory effect to prevent
progression to respiratory failure. Benzodiazepines risk respiratory depression, formoterol alone without
steroids fails to address inflammation, and subcutaneous epinephrine with discharge is appropriate for
anaphylaxis rather than status asthmaticus.
