COMPREHENSIVE EXAM GUIDE 2026/2027
1. A 67-year-old patient with hypertension and diabetes presents with new-onset
confusion and a blood pressure of 218/124 mmHg. Examination reveals
papilledema. Which finding most strongly supports a diagnosis of hypertensive
emergency rather than hypertensive urgency?
A. Long-standing hypertension
B. Headache without neurologic findings
C. Evidence of acute target-organ injury
D. Systolic blood pressure above 180 mmHg
Answer: C
Rationale: Hypertensive emergency is defined by severe blood pressure elevation
accompanied by acute target-organ injury. Papilledema and neurologic dysfunction indicate
end-organ involvement.
2. A hospitalized patient develops sudden dyspnea, pleuritic chest pain, tachycardia,
and oxygen saturation of 88% on room air. Pulmonary embolism is strongly
suspected. Which initial diagnostic strategy is most appropriate in a
hemodynamically stable patient with a moderate pretest probability?
A. Immediate thrombolysis
B. D-dimer testing followed by imaging if positive
C. Bronchoscopy
D. Empiric antibiotics alone
Answer: B
Rationale: In a stable patient with an appropriate clinical probability, D-dimer testing can help
exclude pulmonary embolism when negative; positive results generally require definitive
imaging.
3. A 54-year-old patient reports crushing substernal chest pain radiating to the left
arm. The initial ECG demonstrates ST-segment elevation in contiguous leads. What
is the priority intervention?
A. Arrange urgent reperfusion therapy
B. Schedule outpatient stress testing
C. Administer a proton-pump inhibitor
D. Observe for serial symptoms before treatment
,Answer: A
Rationale: ST-segment elevation in an appropriate clinical setting indicates an acute STEMI
requiring immediate reperfusion therapy to limit myocardial injury.
4. A patient receiving warfarin has a markedly elevated INR but no active bleeding or
evidence of major hemorrhage. Which factor should primarily guide management?
A. The patient's height
B. The patient's blood type
C. The time of the last meal
D. The degree of INR elevation and bleeding risk**
Answer: D
Rationale: Management of excessive anticoagulation depends on the INR level, bleeding
status, and individual bleeding risk rather than unrelated demographic factors.
5. A 72-year-old patient with chronic kidney disease is prescribed a medication that is
substantially eliminated by the kidneys. What is the most appropriate prescribing
principle?
A. Automatically double the dose
B. Consider renal function when determining the dose or interval
C. Ignore renal function if the patient is asymptomatic
D. Administer the medication only at bedtime
Answer: B
Rationale: Renal impairment can reduce drug clearance and increase toxicity. Dose or dosing-
interval adjustment may therefore be necessary.
6. A patient with pneumonia becomes hypotensive despite initial fluid administration
and has evidence of organ dysfunction. Which clinical syndrome should be
suspected?
A. Septic shock
B. Stable angina
C. Chronic venous insufficiency
D. Simple dehydration
Answer: A
Rationale: Persistent hypotension with infection-associated organ dysfunction despite initial
resuscitation is concerning for septic shock and requires immediate escalation of
management.
7. A 45-year-old patient develops unilateral calf swelling and tenderness after
prolonged immobilization. Which diagnosis should be considered most strongly?
, A. Cellulitis only
B. Osteoarthritis
C. Deep vein thrombosis
D. Peripheral neuropathy
Answer: C
Rationale: Unilateral swelling and tenderness in a patient with a thrombotic risk factor are
classic features requiring evaluation for deep vein thrombosis.
8. A patient with asthma presents with increasing wheezing and shortness of breath
after several days of worsening symptoms. Which finding would indicate
particularly severe respiratory compromise?
A. Mild nasal congestion
B. Ability to speak full sentences comfortably
C. Normal respiratory effort
D. Markedly reduced air movement with fatigue
Answer: D
Rationale: Reduced air movement accompanied by fatigue can indicate severe airflow
obstruction and impending respiratory failure.
9. A patient with diabetes becomes confused, diaphoretic, and tremulous. Point-of-care
glucose is 48 mg/dL. What is the most appropriate immediate action for a conscious
patient who can safely swallow?
A. Give rapidly absorbed carbohydrate
B. Administer long-acting insulin
C. Restrict oral intake
D. Give a high-protein meal only
Answer: A
Rationale: Symptomatic hypoglycemia requires prompt administration of rapidly absorbed
glucose or carbohydrate when the patient can safely swallow.
10. A patient with suspected bacterial meningitis presents with fever, severe headache,
neck stiffness, and altered mental status. What is the most important principle
regarding antimicrobial therapy?
A. Delay treatment until all laboratory results are finalized
B. Begin appropriate empiric antimicrobial therapy promptly
C. Treat only if the headache persists for 72 hours
D. Use oral therapy exclusively
Answer: B
, Rationale: Bacterial meningitis is a medical emergency. Appropriate empiric antimicrobial
therapy should not be unnecessarily delayed.
11. A patient with atrial fibrillation has a rapid ventricular response but remains
hemodynamically stable. What is the immediate treatment objective?
A. Permanently eliminate all atrial activity
B. Restore normal sinus rhythm in every case
C. Control the ventricular rate while assessing the broader management strategy
D. Discontinue all cardiovascular medications
Answer: C
Rationale: In a stable patient, ventricular rate control is an important immediate objective
while rhythm control, anticoagulation, and underlying causes are assessed.
12. A patient receiving an ACE inhibitor develops facial swelling and difficulty
breathing. What is the most appropriate interpretation?
A. Expected medication effect
B. Mild dehydration
C. Gastroesophageal reflux
D. Potential ACE inhibitor-associated angioedema
Answer: D
Rationale: Facial or airway swelling in a patient taking an ACE inhibitor may represent
angioedema and requires urgent assessment because airway compromise can develop.
13. A 60-year-old patient presents with progressive fatigue and exertional dyspnea.
Laboratory testing reveals microcytic anemia. Which additional finding would most
strongly suggest iron deficiency?
A. Elevated ferritin from iron overload
B. Low serum ferritin
C. Elevated vitamin B12
D. Macro-ovalocytes
Answer: B
Rationale: Low ferritin is strongly supportive of depleted iron stores and is a key laboratory
feature of iron deficiency.
14. A patient with chronic obstructive pulmonary disease develops increased dyspnea,
sputum volume, and sputum purulence. Which interpretation is most appropriate?
A. Possible acute COPD exacerbation
B. Definite pulmonary embolism
C. Normal disease progression
D. Isolated hypertension
