Rationale: The correct instruction for a client with GERD prescribed omeprazole is to take the medication in the morning before breakfast. Omeprazole works best when taken on an empty stomach, approximately 30 minutes before the first meal of the day. This timing maximizes its effectiveness in reducing stomach acid production and helps manage symptoms of GERD more efficiently.

Correct Answer: A

Rationale: When a client with chronic kidney disease is prescribed sevelamer carbonate, the nurse should monitor for hypercalcemia as a potential side effect. Sevelamer carbonate can bind to dietary calcium and impair its absorption, potentially leading to elevated calcium levels in the blood. Monitoring calcium levels is crucial to detect and manage hypercalcemia promptly.

Correct Answer: A

Rationale: Correct. Diazepam, a medication commonly used to treat anxiety disorders, can lead to drowsiness as a potential side effect. It is important for clients taking diazepam to be cautious about activities that require alertness, such as driving, due to the risk of drowsiness associated with this medication.

Correct Answer: A

Rationale: Bradycardia is a common sign of digoxin toxicity. Digoxin, a medication used to treat atrial fibrillation, can lead to toxicity manifesting as various cardiac dysrhythmias, with bradycardia being a notable indicator. Monitoring for bradycardia is crucial as it can indicate the need for dosage adjustment or discontinuation of digoxin to prevent adverse effects.

Correct Answer: D

Rationale: The client's low heart rate of 48 beats/min indicates bradycardia, a potential side effect of labetalol. Administering the dose in this case could further lower the heart rate, potentially causing adverse effects. Therefore, it is crucial to withhold the scheduled dose and notify the healthcare provider for further assessment and guidance.
