Correct Answer: B

Rationale: The correct answer is B: 'It can cause bradycardia.' Digoxin can cause bradycardia as one of its side effects. Clients should be educated about this potential effect and instructed to monitor their heart rate before taking the medication. Choice A is incorrect because digoxin is more likely to cause arrhythmias than low blood pressure. Choice C is incorrect as calcium supplements can interfere with the absorption of digoxin. Choice D is incorrect as digoxin has various side effects, and clients should be aware of them.

Correct Answer: B

Rationale: The correct answer is B: Renal function. Gabapentin is primarily eliminated by the kidneys, so monitoring renal function is essential to ensure the drug is being cleared effectively from the body. Monitoring liver function tests (choice A) is not a priority for gabapentin as it is not primarily metabolized by the liver. Blood glucose levels (choice C) are not directly impacted by gabapentin. Cardiac rhythm (choice D) monitoring is not typically necessary for clients on gabapentin unless they have pre-existing cardiac conditions that may be exacerbated by the medication.

Correct Answer: B

Rationale: The correct answer is to monitor signs of diarrhea when a client is prescribed azithromycin. Azithromycin is known to cause gastrointestinal side effects, particularly diarrhea. Monitoring for diarrhea is crucial to assess the client's response to the medication and to prevent complications such as dehydration. Monitoring liver function (choice A), blood glucose levels (choice C), and serum electrolytes (choice D) are not typically indicated specifically for clients prescribed azithromycin unless there are other specific reasons or conditions that warrant such monitoring.

Correct Answer: C

Rationale: In a fire emergency, the priority for the nurse is to ensure safety. The correct first action is to evacuate the room, following the RACE protocol, which stands for Rescue, Alarm, Contain, and Extinguish/Evacuate. Activating the fire alarm alerts others, extinguishing the fire can escalate the situation if not done correctly, and calling the client's family is not a priority in this emergency scenario.

Correct Answer: B

Rationale: The correct answer is B: Fatigue. Fatigue, along with symptoms like shakiness and irritability, are common signs of hypoglycemia. Increased thirst (Choice A) is more indicative of hyperglycemia. Weight gain (Choice C) is not typically associated with hypoglycemia. Elevated blood pressure (Choice D) is not a common sign of hypoglycemia.
