Cardiovascular Disease Questions and Answers Questions
Question 1 of 5
In Leukemia, all are true except:
Correct Answer: A
Rationale: Acute leukemia can present with normal or low WBC (e.g., aleukemic leukemia), not always elevated. CLL is often asymptomatic, CML may present with infections, and Ph chromosome variants exist.
Question 2 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 3 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 4 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.
Question 5 of 5
Which of the following is a correct statement about the pharmacodynamics of Beta-blockers for the treatment of heart failure?
Correct Answer: B
Rationale: Beta-blockers cause bradycardia (B) by reducing heart rate and contractility (negative inotropic effect), contrary to A. They're used with ACE/ARBs (D) but avoided in COPD (C).
