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?

The client needs immediate medical evaluation and possibly urgent dialysis, which is best managed in an emergency department.Choice C reason: Checking for a thrill and bruit is important but does not address the immediate need for medical intervention.Choice D reason: Avoiding salt intake is a good general recommendation but does not address the acute symptoms caused by missing dialysis.
