Cardiovascular System Anatomy Questions and Answers Questions
Question 1 of 4
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 2 of 4
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 3 of 4
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.
Question 4 of 4
Which of the following is not a component of the cardiovascular system?
Correct Answer: D
Rationale: The cardiovascular system includes the heart, blood vessels, and blood, which work together to circulate blood throughout the body. The kidneys (Choice D), while vital for filtering blood and regulating fluid balance as part of the urinary system, are not a direct component of the cardiovascular system. The heart (Choice A) pumps blood, blood vessels (Choice C) transport it, and although the lungs (Choice B) oxygenate blood via pulmonary circulation, they belong to the respiratory system, not the cardiovascular system. However, the provided answer specifies kidneys, which aligns with their exclusion from the core circulatory components.
