Questions About the Cardiovascular System Questions
Question 1 of 5
What is the most important nursing intervention for a client prescribed furosemide for pulmonary edema secondary to heart failure?
Correct Answer: C
Rationale: Furosemide can cause hypokalemia, so potassium levels must be monitored.
Question 2 of 5
What is a priority nursing assessment when administering an ACE inhibitor to a patient with heart failure?
Correct Answer: A
Rationale: ACE inhibitors can cause hyperkalemia, so the nurse should monitor for signs like muscle weakness, which could indicate elevated potassium levels.
Question 3 of 5
The heart valves do all of the following, EXCEPT:
Correct Answer: C
Rationale: The heart valves manage blood flow direction, not the timing or strength of contractions, which is controlled by the heart's electrical system.
Question 4 of 5
A 34 y/o female presents with blood pressure = 180/101 on Lisinopril, Amlodipine and HCTZ. BMI = 23. Electrolytes, bun and creatinine are normal. No family history of hypertension. She reports diaphoresis. Carvedilol is added with a spike in blood pressure and tachycardia. Which of the following is most likely to be elevated as the etiology of the underlying diagnosis?
Correct Answer: A
Rationale: The severe hypertension resistant to multiple medications, diaphoresis, and paradoxical worsening with a beta-blocker (Carvedilol) suggest pheochromocytoma, a catecholamine-secreting tumor. Elevated urine metanephrines (catecholamine metabolites) are diagnostic. Aldosterone (Conn's syndrome) or cortisol (Cushing's) would present differently.
