1. A 67-year-old client is discharged from the hospital with a prescription for digoxin 0.25 mg daily. Which instruction by the practical nurse (PN) is correct?

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. Choices A, C, and D are incorrect. Taking digoxin in the morning before getting out of bed is not a specific requirement. Vision changes are not a common side effect of digoxin. While digoxin can affect potassium levels, it is not advised to increase potassium intake without healthcare provider guidance.

2. A client with a diagnosis of generalized anxiety disorder is prescribed buspirone. The nurse should include which instruction in the client's teaching plan?

Correct answer: B

Rationale: Buspirone may take several weeks to take effect, so clients should continue taking it as prescribed and not expect immediate relief.

3. The practical nurse is assigned a client on digoxin therapy. Which finding is likely to predispose this client to developing digoxin toxicity?

Correct answer: D

Rationale: Hypokalemia predisposes a client on digoxin to digoxin toxicity. Symptoms of digoxin toxicity include abdominal pain, anorexia, nausea, vomiting, visual disturbances, bradycardia, and atrioventricular (AV) dissociation. Therefore, assessment of serum potassium levels and prompt correction of hypokalemia are crucial interventions for clients taking digoxin.

4. A client with a diagnosis of generalized anxiety disorder is prescribed lorazepam. The client should be informed that this medication may have which potential side effect?

Correct answer: A

Rationale: The correct answer is A: Drowsiness. Lorazepam, a medication commonly used to treat anxiety disorders, can lead to drowsiness as a common side effect. It is important for clients to be aware of this potential effect, and they should be advised to avoid activities like driving until they understand how the medication affects them. Dry mouth, nausea, and headache are possible side effects of other medications but are less commonly associated with lorazepam.

5. While a client is receiving the medication haloperidol, which client data would indicate to the practical nurse that the medication is therapeutic?

Correct answer: B

Rationale: When a client is taking haloperidol, a therapeutic response involves a decrease in symptoms such as paranoia, hallucinations, delusions, and emotional excitement. These improvements indicate that the medication is effectively managing the client's condition. Monitoring for a reduction in paranoid behaviors helps the practical nurse assess the medication's effectiveness in addressing the client's psychiatric symptoms.
