Cardiovascular System Assessment Questions Questions
Question 1 of 5
Arteries serving the stomach, pancreas, and liver all branch from the
Correct Answer: C
Rationale: The celiac trunk (C) supplies the stomach, pancreas, and liver. Mesenteric arteries (A, B) serve intestines, splenic (D) is a branch of celiac.
Question 2 of 5
The two tubes that eventually fuse to form the heart are referred to as the
Correct Answer: B
Rationale: Endocardial tubes (B) fuse to form the primitive heart tube in the embryo.
Question 3 of 5
Which of the following interventions should the nurse include in the plan of care for a client taking an ACE inhibitor?
Correct Answer: A
Rationale: ACE inhibitors (A) can cause first-dose hypotension, requiring BP monitoring for 2 hours. High doses (B), potassium supplements (C), and alternate dosing (D) are incorrect.
Question 4 of 5
A slow heart rate is known as:
Correct Answer: A
Rationale: Bradycardia refers to a slow heart rate, typically below 60 beats per minute in adults. Tachycardia is a fast heart rate (above 100 bpm), while 'hypocardia' and 'hypercardia' are not standard medical terms related to heart rate.
Question 5 of 5
The following statements concern carotid sinus discharge. Which combination is correct? A. No discharge when carotid sinus perfusion pressure was below 30 mm Hg. B. Linear increase in discharge frequency when carotid sinus perfusion pressure was gradually increased from 70 to 110 mm Hg. C. Increase in discharge frequency was more prominent in greater pulsatile changes of carotid sinus pressure keeping the mean pressure identical. D. Increase in discharge was more prominent in the falling phase of pulsatile change.
Correct Answer: B
Rationale: The carotid sinus baroreceptors detect blood pressure changes. A is true (below ~30 mmHg, discharge ceases), B is true (discharge increases linearly in the 70-110 mmHg range), C is true (pulsatile pressure enhances sensitivity), but D is false (rising phase typically triggers more discharge). B (B and C) is correct.
