Cardiovascular Disease Questions and Answers Questions
Question 1 of 5
A 56 yo woman with a history of atrial fibrillation presents with 3 hours of acute-onset aphasia, hemiparesis, neglect, and forced gaze deviation. CT was WNL. The most common reason for this is:
Correct Answer: B
Rationale: In the first few hours after an ischemic stroke, CT scans may appear normal despite significant clinical findings due to the time it takes for changes to become visible.
Question 2 of 5
Which test is necessary for the diagnostic evaluation for fevers of unknown origin?
Correct Answer: D
Rationale: All listed tests (blood cultures, HIV antibody test, and tuberculin skin test or interferon-gamma release assay) are essential in the comprehensive evaluation of fevers of unknown origin to identify infectious, inflammatory, or other causes.
Question 3 of 5
A 63-year-old past medical history of hypertension diabetes presents with community-acquired pneumonia that progresses to acute respiratory distress syndrome. On hospital, mechanical ventilation is initiated. Continuous enteral nutrition is started by a 14-French nasogastric targeted to deliver 25 kcals per kilogram per day. Which of the following strategies would be implemented to reduce ventilator-associated pneumonia during mechanical ventilation?
Correct Answer: B
Rationale: Elevating the head of the bed reduces aspiration risk and is a key strategy to prevent ventilator-associated pneumonia.
Question 4 of 5
Hypertrophy of the right ventricle is a compensatory response to
Correct Answer: D
Rationale: Right ventricular hypertrophy is the direct result of pulmonary disorders that increase pulmonary vascular resistance and impose a high afterload on the right ventricle. Aortic stenosis does not lead to right ventricular hypertrophy. Aortic regurgitation is not associated with right ventricular hypertrophy. Hypertrophy of the right ventricle is not a compensatory response to tricuspid stenosis.
Question 5 of 5
A patient has heart failure with a normal ejection fraction. Which findings are most likely found in this patient?
Correct Answer: B
Rationale: Pulmonary congestion is a hallmark sign of heart failure. Edema is also a hallmark sign of heart failure. An ejection fraction greater than 50% indicates a normal ejection fraction. Low cardiac output, not high cardiac output, is a sign of heart failure. An ejection fraction of less than 45% indicates an abnormal ejection fraction.
