Cardiovascular Disease Questions and Answers Questions
Question 1 of 5
A 55-year-old female presents with palpitations and lightheadedness. Her ECG shows a regular narrow-complex tachycardia at a rate of 180 bpm. What is the first-line treatment?
Correct Answer: A
Rationale: Adenosine is the first-line treatment for supraventricular tachycardia due to its ability to transiently block AV nodal conduction.
Question 2 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 3 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 4 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 5 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.
