Cardiovascular Disease Questions and Answers Questions
Question 1 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 2 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 3 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 4 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).
Question 5 of 5
The nurse is caring for a 70-yr-old patient who takes hydrochlorothiazide and enalapril(Norvasc). The patient's blood pressure(BP) continues to be high. Which patient information may indicate a need for a change?
Correct Answer: B
Rationale: Because use of nonsteroidal anti-inflammatory drugs(NSAIDs) can prevent adequate BP control, the patient may need to avoid the use of ibuprofen. A multivitamin tablet will help supply vitamin D, which may help lower BP. BP decreases while sleeping, so self-monitoring early in the morning will result in obtaining pressures that are at their lowest. The patient's alcohol intake is not excessive.
