A client is prescribed an antibiotic for a urinary tract infection (UTI). What instruction should the practical nurse (PN) provide to the client to ensure the effectiveness of the medication?

Correct Answer: C

Rationale: The practical nurse (PN) should instruct the client to complete the full course of the antibiotic to ensure the infection is fully treated and to prevent the development of antibiotic resistance. Completing the full course of antibiotics helps to eradicate the infection completely and reduces the risk of bacteria developing resistance to the medication.

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: 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.

Correct Answer: B

Rationale: The correct instruction that the practical nurse (PN) should reinforce with a client prescribed nitrate isosorbide dinitrate is to avoid getting up quickly and to rise slowly. Nitrates can cause orthostatic hypotension, a sudden drop in blood pressure when changing positions. By rising slowly, the client can prevent the occurrence of orthostatic hypotension and its associated symptoms.

Correct Answer: A

Rationale: The correct answer is A. Phenobarbital should be taken at the same time every day to maintain blood levels and enhance compliance. Common side effects of phenobarbital include drowsiness, lethargy, dizziness, and nausea; therefore, it is best to take it before bedtime to minimize these effects and improve sleep quality.
