QUESTION 1
A 58-year-old male presents with crushing substernal chest pain radiating to
the
left arm. ECG shows ST-segment elevation in leads II, III, aVF. Which immediate
medication is indicated?
A) Metoprolol 5 mg IV
B) Nitroglycerin 0.4 mg SL
C) Alteplase 100 mg IV infusion
D) Aspirin 325 mg PO
2
,Answer: D
Rationale: While reperfusion (fibrinolysis or PCI) is the definitive therapy,
the FIRST immediate medication in ANY suspected STEMI is aspirin (chewable
325 mg) to reduce mortality. Fibrinolysis (alteplase) is indicated only if PCI
is not available within 120 minutes of first medical contact. Metoprolol and
NTG are adjunctive but not the single most immediate first-line drug.
QUESTION 2
A patient arrives with a Glasgow Coma Scale of 6, unequal pupils, and a CT scan
showing a crescent-shaped hyperdensity crossing the midline. What is the most
likely diagnosis?
A) Epidural hematoma
B) Subdural hematoma
C) Subarachnoid hemorrhage
D) Intracerebral hemorrhage
Answer: B
Rationale: Subdural hematomas appear crescent-shaped (concave) and can
cross suture lines, frequently associated with significant mass effect and
herniation
in the setting of high ICP. Epidural hematomas are lens-shaped (biconvex) and
do not cross sutures.
QUESTION 3
According to the Emergency Severity Index (ESI), which of the following
patients
should be classified as level 1?
A) A 30-year-old with a simple laceration requiring sutures
B) A 72-year-old with acute shortness of breath, hypotension, and altered
mental status
C) A child with otitis media and fever of 38.5 °C
D) An adult with abdominal pain, stable vitals, and no comorbidities
Answer: B
Rationale: ESI Level 1 is reserved for patients who require immediate life-
saving intervention – e.g., impending respiratory/cardiac arrest. The 72-year-
old with acute SOB, hypotension, and AMS is unstable and requires immediate
3
, resuscitation. Option A is Level 4 or 5; C and D are Level 3 or 4.
QUESTION 4
A 45-year-old with a history of IV drug use presents with fever, tricuspid
regurgitation murmur, and septic pulmonary emboli. Blood cultures grow
Gram-
positive cocci in clusters. Which antibiotic regimen is most appropriate
empirically?
A) Vancomycin + Piperacillin-Tazobactam
B) Ceftriaxone + Azithromycin
C) Vancomycin + Gentamicin
D) Nafcillin + Gentamicin
Answer: A
Rationale: This is infective endocarditis (tricuspid valve) in an IVDU. Given
high MRSA prevalence in this population, empiric vancomycin is mandatory.
Piperacillin-tazobactam provides broad Gram-negative and anaerobic coverage
for possible concomitant sepsis. Vancomycin + gentamicin is synergistic but
gentamicin is usually added only after sensitivities or for prosthetic valves.
QUESTION 5
A 28-year-old G1P0 at 32 weeks gestation presents with a severe headache,
visual blurring, and epigastric pain. BP is 165/105 mmHg. Urine protein is
4 g/24h. Which of the following is the most appropriate definitive
management?
A) Labetalol 20 mg IV push
B) Magnesium sulfate 4 g IV bolus
C) Emergent cesarean section
D) Delivery of the fetus
Answer: D
Rationale: This patient has severe pre-eclampsia with concerning features
(headache, visual changes, epigastric pain). Magnesium sulfate is given for
seizure prophylaxis, and antihypertensives (labetalol) are used to control
BP, but the ONLY definitive treatment for pre-eclampsia/eclampsia is delivery
of the fetus and placenta. Emergent cesarean is not always indicated unless
obstetrical contraindications to vaginal delivery exist.
