NCLEX Cardiovascular Questions Questions
Question 1 of 5
Beta-blockers are advocated in the management of heart failure because they
Correct Answer: B
Rationale: Beta-blockers are advocated in the management of heart failure to inhibit the cardiac effects of sympathetic activation. These drugs are negative inotropes and have the potential to reduce cardiac output. The goal with the use of beta-blockers in heart failure is to reduce cardiac output. Beta-blockers do not affect sodium reabsorption. Angiotensin II and aldosterone enhance sodium and water reabsorption by the kidney, contributing to an elevated blood volume.
Question 2 of 5
The nurse has just finished teaching a hypertensive patient about a newly prescribed drug, ramipril(Altace). Which patient statement indicates that more teaching is needed?
Correct Answer: B
Rationale: Angioedema occurring with angiotensin-converting enzyme(ACE) inhibitor therapy is an indication that the ACE inhibitor should be discontinued. The patient should be taught that if any swelling of the face or oral mucosa occurs, the health care provider should be immediately notified because this could be life threatening. The other patient statements indicate that the patient has an accurate understanding of ACE inhibitor therapy.
Question 3 of 5
Blood enters the systemic circuit of blood flow by passing through the
Correct Answer: B
Rationale: The aortic valve allows blood to exit the left ventricle into the aorta, initiating the systemic circuit.
Question 4 of 5
Which nursing action should the nurse take first in order to assist a patient with newly diagnosed stage 1 hypertension in making needed dietary changes?
Correct Answer: A
Rationale: The initial nursing action should be assessment of the patient's baseline dietary intake through a thorough diet history. The other actions may be appropriate, but assessment of the patient's baseline should occur first.
Question 5 of 5
The nurse is teaching a patient about some of the health consequences of uncontrolled hypertension. What is the most significant health consequence the nurse should emphasize?
Correct Answer: A
Rationale: Potential complications of hypertension include the following: left ventricular hypertrophy; MI; heart failure; transient ischemic attacks (TIAs); cerebrovascular accident; renal insufficiency and failure; and retinal hemorrhage. Venous insufficiency and right ventricular hypertrophy are not potential complications of uncontrolled hypertension. The original question was a multiple-answer type, but it has been restructured to a single-answer format emphasizing a key consequence (TIAs) while maintaining accuracy.
