Extract:
Question 1 of 5
Which statement, made by a client receiving pharmacologic therapy for hypertension, indicates a need for further clarification by the nurse?
Correct Answer: D
Rationale: Hypertension requires lifelong management. Stopping medication when blood pressure normalizes can lead to rebound hypertension, necessitating further education.
Question 2 of 5
A client is scheduled to receive atenolol 25 mg PO and diltiazem 60 mg PO at 0800. The nurse assesses the client's heart rate as 45 beats/minute and irregular. What is the best nursing action at this time?
Correct Answer: C
Rationale: Holding atenolol prevents further bradycardia, while diltiazem may help regulate rhythm, addressing the low, irregular heart rate.
Question 3 of 5
The nurse is evaluating the effects of the prescribed carvedilol 6.25 mg PO daily for a client with a history of unstable angina. Which of the following reflects that the medication has been effective?
Correct Answer: A
Rationale: Resolution of exertional dyspnea indicates improved cardiac function and oxygen supply, showing carvedilol's effectiveness.
Question 4 of 5
The nurse should monitor the client for clinical manifestations of digoxin toxicity if the laboratory report reflects a serum:
Correct Answer: B
Rationale: Low serum potassium (3.0 mEq/L) increases the risk of digoxin toxicity by enhancing digoxin binding to cardiac cells, leading to symptoms like nausea, confusion, and arrhythmias. Other options (glucose, calcium, sodium) are not directly linked to digoxin toxicity.
Question 5 of 5
The nurse, who is assessing a client with peripheral vascular disease, notes that the client has no hair on the legs and has thick toenails. Which statement describes the cause of this finding?
Correct Answer: C
Rationale: Peripheral vascular disease reduces blood flow, leading to tissue ischemia, which causes hair loss and nail changes due to decreased oxygen delivery.
