A client with chronic kidney disease (CKD) missed dialysis yesterday to attend a funeral. The client's spouse calls the home health nurse and reports that the client is lethargic and hard to arouse. Which instruction is most important for the nurse to provide?

Choice A reason: Taking the client to the emergency department is crucial because missing a dialysis session can lead to severe complications such as fluid overload, high potassium levels, and other electrolyte imbalances. These conditions can be life-threatening and require immediate medical attention to stabilize the client.Choice B reason: Applying home oxygen is not the most critical intervention in this scenario. While oxygen therapy might be necessary in some cases, it does not address the immediate risk of complications arising from missed dialysis.Choice C reason: Ensuring that the client avoids salt intake for the rest of the day is important for managing fluid balance, but it is not the most urgent action needed in this situation. The client's lethargy and difficulty arousing indicate a more serious underlying issue that requires immediate medical evaluation.Choice D reason: Checking for a thrill and bruit at the client's dialysis access site is important for assessing the patency of the access site, but it is not the most critical action in this scenario. The immediate concern is the client's lethargy and potential complications from missed dialysis, which necessitate emergency medical care.
