Correct Answer: C

Rationale: The correct answer is C. Enalapril, an ACE inhibitor, inhibits the conversion of angiotensin I to angiotensin II, leading to increased levels of bradykinin. The accumulation of bradykinin is responsible for the persistent dry cough associated with ACE inhibitors like enalapril.

Correct Answer: A

Rationale: The most important nursing intervention before administering ampicillin to a client with a urinary tract infection is to obtain a clean-catch urine specimen. This specimen is crucial for determining the causative organism and evaluating the effectiveness of pharmacological therapy. It should be collected before starting treatment with an anti-infective agent to ensure accurate diagnosis and appropriate management of the infection.

Correct Answer: D

Rationale: A glucagon emergency kit is used when signs of severe hypoglycemia occur in a client with Type 1 diabetes. Glucagon helps to raise blood glucose levels in cases of severe hypoglycemia where the individual is unable to take oral glucose. It is crucial to administer glucagon promptly to prevent serious complications associated with low blood sugar levels.

Correct Answer: A

Rationale: Digoxin, a medication commonly prescribed for heart failure, can lead to bradycardia, which is characterized by a slow heart rate. Monitoring for bradycardia is crucial to detect and manage this potential side effect early on to prevent complications such as arrhythmias or decreased cardiac output.

Correct Answer: B

Rationale: The correct instruction for a client taking digoxin is not to take the medication if the heartbeat is irregular or slow. Digoxin can affect the heart rhythm, so it is crucial to monitor the pulse rate. In case of irregular or slow heartbeats, the medication should be withheld, and the healthcare provider should be consulted. This step is necessary to prevent potential complications associated with digoxin therapy.
