1. A 68-year-old patient with hypertension, diabetes, and chronic kidney
disease has an eGFR of 32 mL/min/1.73 m² and persistent albuminuria
despite an ACE inhibitor. Which additional medication class provides kidney
and cardiovascular protection in appropriate patients?
A. Thiazolidinedione
B. SGLT2 inhibitor
C. Sulfonylurea
D. DPP-4 inhibitor
Answer: B. SGLT2 inhibitor
Rationale: SGLT2 inhibitors can reduce progression of chronic kidney disease and
cardiovascular events in appropriate patients with type 2 diabetes and/or
chronic kidney disease. Their benefits extend beyond glucose lowering.
2. A patient taking warfarin presents with an INR of 8.2 but has no active
bleeding. Which intervention is most appropriate for a significantly
elevated INR without bleeding?
,A. Continue the current dose
B. Administer protamine sulfate
C. Hold warfarin and consider oral vitamin K based on bleeding risk
D. Administer idarucizumab
Answer: C. Hold warfarin and consider oral vitamin K based on bleeding risk
Rationale: For markedly elevated INR without bleeding, warfarin is withheld
and vitamin K may be administered depending on the INR and clinical bleeding
risk. Protamine reverses heparin, while idarucizumab reverses dabigatran.
3. A 54-year-old patient reports episodic palpitations. ECG demonstrates an
irregularly irregular rhythm without identifiable P waves. Which diagnosis is
most likely?
A. Atrial flutter
B. Multifocal atrial tachycardia
C. Atrial fibrillation
D. Supraventricular tachycardia
Answer: C. Atrial fibrillation
Rationale: Atrial fibrillation classically produces an irregularly irregular
ventricular rhythm and absent organized P waves. Management includes
assessment of hemodynamic stability, stroke risk, and rate or rhythm control.
4. A patient with suspected bacterial meningitis is hypotensive and febrile.
What is the priority intervention after obtaining appropriate cultures when
this can be done without delaying therapy?
A. Begin empiric antimicrobial therapy promptly
B. Obtain an MRI before treatment
C. Wait for lumbar puncture results
D. Administer corticosteroids alone
Answer: A. Begin empiric antimicrobial therapy promptly
,Rationale: Suspected bacterial meningitis is a medical emergency. Antimicrobial
therapy should not be substantially delayed for imaging or lumbar puncture
when those procedures cannot be performed immediately.
5. A patient with type 1 diabetes presents with glucose 480 mg/dL, abdominal
pain, vomiting, Kussmaul respirations, and a high anion gap. Which
condition is most likely?
A. Hyperosmolar hyperglycemic state
B. Diabetic ketoacidosis
C. Lactic acidosis
D. Metabolic alkalosis
Answer: B. Diabetic ketoacidosis
Rationale: Hyperglycemia, ketosis, high-anion-gap metabolic acidosis,
gastrointestinal symptoms, and Kussmaul respirations are characteristic of
diabetic ketoacidosis.
6. A 72-year-old patient develops sudden unilateral weakness and aphasia 45
minutes before arrival. What is the most important initial diagnostic study?
A. Noncontrast head CT
B. Carotid ultrasound
C. EEG
D. Lumbar puncture
Answer: A. Noncontrast head CT
Rationale: A rapid noncontrast CT is used to determine whether intracranial
hemorrhage is present and to support decisions regarding acute reperfusion
therapy.
7. A patient taking lisinopril develops facial swelling and difficulty breathing.
Which adverse reaction is most likely?
A. Stevens-Johnson syndrome
B. Angioedema
, C. Serum sickness
D. Anaphylactic shock caused by IgE antibodies
Answer: B. Angioedema
Rationale: ACE inhibitors can cause bradykinin-mediated angioedema involving
the lips, tongue, face, and airway. The medication should be discontinued and
airway management prioritized.
8. A patient with COPD has increased dyspnea, sputum volume, and purulent
sputum. Which treatment combination is generally appropriate for an
acute exacerbation?
A. Long-term oxygen alone
B. Short-acting bronchodilators with systemic corticosteroids
C. Inhaled corticosteroid monotherapy
D. Immediate lung transplantation
Answer: B. Short-acting bronchodilators with systemic corticosteroids
Rationale: Acute COPD exacerbations are commonly treated with increased
short-acting bronchodilator therapy and a short course of systemic
corticosteroids. Antibiotics may be indicated in selected patients, particularly
with increased sputum purulence.
9. A patient presents with crushing substernal chest pain and ST-segment
elevation in contiguous leads. What diagnosis should be assumed until
proven otherwise?
A. Stable angina
B. STEMI
C. Pericarditis
D. Panic disorder
Answer: B. STEMI
