Cardiovascular System Anatomy Questions and Answers Questions
Question 1 of 5
Based on an understanding of beta blockers used for unstable angina, the nurse administers a beta blocker because of which of the following actions?
Correct Answer: B
Rationale: Beta blockers (B) decrease heart rate, reducing oxygen demand in unstable angina. They don’t increase contractility (A), shift fluids (C), or vasodilate coronaries (D).
Question 2 of 5
Problems related to heart valves can be categorized into three main types: Regurgitation, Stenosis, and Atresia. Which of the following is correct about Atresia?
Correct Answer: A
Rationale: Atresia is a congenital condition where a valve (or other structure) fails to develop properly, resulting in no opening (e.g., pulmonary atresia). B describes regurgitation, C describes stenosis, and D refers to prolapse, not atresia.
Question 3 of 5
Which of the following should the nurse include in the plan of care for a client following a coronary angiogram?
Correct Answer: B
Rationale: Encouraging fluids helps flush out the contrast dye used in a coronary angiogram, reducing kidney strain. Stress tests are post-recovery, vigorous exercise risks bleeding at the catheter site, and 4-6 weeks restriction is excessive.
Question 4 of 5
When reviewing a patient's four-week diet history, the cardiac-vascular nurse identifies a pattern of high-calorie intake on Monday, Wednesday, and Friday nights. The patient states that their spouse recently started taking a night class on those evenings at a local university. The patient's diet history indicates:
Correct Answer: D
Rationale: High-calorie intake on specific nights linked to the spouse’s absence suggests an individual coping behavior (e.g., emotional eating), not a family issue (A), lack of knowledge (B), or cooking skill deficit (C), but a personal response to stress or loneliness.
Question 5 of 5
A patient with negative troponins and stress test results reports recurring chest pain that is similar to their pain on admission. According to the American Nurses Association’s Cardiovascular Nursing: Scope and Standards of Practice, the cardiac-vascular nurse’s next action is to:
Correct Answer: C
Rationale: Recurring chest pain despite negative tests warrants a 12-lead ECG to assess for ischemia or arrhythmia, per nursing standards for objective evaluation. A is premature, B treats without diagnosis, and D delays assessment.
