1. A 67-year-old man with hypertension, type 2 diabetes mellitus,
and stage 3 chronic kidney disease presents with crushing
substernal chest pain radiating to his left arm for 90 minutes. ECG
demonstrates ST-segment elevations in leads II, III, and aVF. Blood
pressure is 88/60 mm Hg. Which intervention should be
performed immediately?
A. Intravenous metoprolol
B. Sublingual nitroglycerin
C. Emergent coronary angiography with PCI
D. Intravenous alteplase despite PCI availability
E. Observation with serial troponins
Answer: C. Emergent coronary angiography with PCI
Rationale: Inferior STEMI with hypotension suggests cardiogenic
compromise. Primary PCI is the preferred reperfusion strategy when
available. Nitroglycerin may worsen hypotension, particularly in right
ventricular infarction.
2. A 24-year-old woman at 32 weeks' gestation develops severe
headache, visual disturbances, blood pressure of 176/112 mm Hg,
and 4+ proteinuria. Which medication should be administered
first to prevent maternal complications?
,A. Oxytocin
B. Methyldopa
C. Magnesium sulfate
D. Terbutaline
E. Indomethacin
Answer: C. Magnesium sulfate
Rationale: Severe preeclampsia carries significant risk for eclamptic
seizures. Magnesium sulfate is the treatment of choice for seizure
prophylaxis.
3. A 72-year-old nursing home resident develops fever, dysuria,
confusion, and hypotension. Urinalysis reveals numerous WBCs
and nitrites. Lactate is elevated. What is the most appropriate
next step?
A. Wait for urine culture results
B. Begin broad-spectrum IV antibiotics and fluid resuscitation
C. Repeat urinalysis in 24 hours
D. Oral antibiotics only
E. Discharge with outpatient follow-up
Answer: B. Begin broad-spectrum IV antibiotics and fluid resuscitation
Rationale: This patient meets criteria for septic shock. Early antibiotics
and aggressive fluid resuscitation significantly improve survival.
4. A 59-year-old man with cirrhosis presents with hematemesis and
hypotension. Endoscopy confirms bleeding esophageal varices.
Which pharmacologic therapy should be started immediately?
A. Omeprazole alone
B. Octreotide infusion
C. Metoclopramide
,D. Misoprostol
E. Sucralfate
Answer: B. Octreotide infusion
Rationale: Octreotide reduces portal venous pressure and is first-line
pharmacologic treatment for acute variceal hemorrhage.
5. A 43-year-old woman develops sudden unilateral weakness and
aphasia 90 minutes before arrival. CT scan shows no hemorrhage.
Which treatment is most appropriate?
A. Aspirin only
B. Heparin infusion
C. Alteplase administration
D. Neurosurgical decompression
E. Observation
Answer: C. Alteplase administration
Rationale: Acute ischemic stroke within the therapeutic window and
without contraindications is treated with thrombolysis.
6. A patient with diabetic ketoacidosis has a serum potassium of 2.9
mEq/L. What should occur before insulin therapy?
A. Administer bicarbonate
B. Administer potassium replacement
C. Start insulin immediately
D. Give calcium gluconate
E. Restrict fluids
Answer: B. Administer potassium replacement
Rationale: Insulin drives potassium intracellularly and may precipitate
life-threatening hypokalemia. Potassium must be corrected first.
, 7. A 70-year-old woman presents with acute onset dyspnea, pleuritic
chest pain, tachycardia, and hypoxemia following hip surgery.
Most likely diagnosis?
A. CHF exacerbation
B. COPD exacerbation
C. Pulmonary embolism
D. Pneumonia
E. Pneumothorax
Answer: C. Pulmonary embolism
Rationale: Recent orthopedic surgery is a major risk factor for venous
thromboembolism.
8. A 29-year-old woman develops fever, hypotension, diffuse rash,
and multiorgan dysfunction during menstruation. Most likely
pathogen?
A. Escherichia coli
B. Streptococcus pneumoniae
C. Staphylococcus aureus
D. Mycoplasma pneumoniae
E. Listeria monocytogenes
Answer: C. Staphylococcus aureus
Rationale: Toxic shock syndrome is classically associated with toxin-
producing S. aureus.
9. A patient with severe asthma remains dyspneic despite multiple
nebulized treatments. Peak flow is less than 30% predicted. What
is the next step?
A. Discharge home
B. Oral antihistamines
