A client with end-stage Alzheimer's disease is brought to the clinic by the caregiver for an appointment with the healthcare provider. The caregiver speaks privately to the nurse about not sleeping well at night and experiencing frequent periods of crying. Which intervention should the nurse implement?

A. anaphylaxis

The correct answer is A. Anaphylaxis is a severe, life-threatening allergic reaction that can occur in response to medication administration. The client's symptoms of dizziness, headache, burning feeling on extremities, and redness on face and extremities, along with the sudden onset of symptoms after starting vancomycin infusion, are indicative of a possible anaphylactic reaction.

B. arrhythmias

The correct answer is B. Arrhythmias refer to abnormal heart rhythms, which can be

triggered by various factors including medication reactions. Given the client's history of symptomatic bradycardia and the sudden onset of symptoms after starting vancomycin infusion, arrhythmias such as bradycardia or other rhythm disturbances are a concern.

C. Cardiac arrest

The correct answer is C. Cardiac arrest is the cessation of normal heart function, which can be precipitated by severe arrhythmias or anaphylaxis. The client's symptoms, along with the drop in blood pressure, indicate a potential risk of progressing to cardiac arrest if not promptly treated.

D. Necrosis

Necrosis, or tissue death, is not typically associated with the symptoms described in the scenario. While vancomycin infusion can potentially cause tissue irritation or damage at the
injection site, the symptoms described suggest a systemic reaction rather than localized tissue necrosis.

E. Renal failure

Renal failure is not directly indicated by the symptoms described in the scenario. While vancomycin can be nephrotoxic in some cases, the symptoms of dizziness, headache, and redness are more suggestive of an allergic or cardiovascular reaction.

F. Peripheral edema

Peripheral edema, or swelling in the extremities, is not indicated by the symptoms described in the scenario. The client's symptoms, such as dizziness, headache, and redness, are more
indicative of a systemic reaction rather than localized swelling.

A. For the next 24 hours, notify the nurse when the bladder is full, and the nurse will collect

catheterized specimens: This instruction is incorrect for a 24-hour urine collection. Catheterized specimens are not typically used for creatinine clearance tests, and the nurse should not be notified when the bladder is full.
B. Urinate immediately into a urinal, and the lab will collect the specimen every 6 hours for the next 24 hours: This instruction is incorrect for a 24-hour urine collection. Creatinine clearance
tests require collection of all urine produced over a 24-hour period, not just specimens at specific intervals.
C. Urinate at a specified time, discard this urine, and collect all subsequent urine during the next 24 hours: This is the correct instruction for a 24-hour urine collection. The client should begin by discarding the first voided urine and then collect all subsequent urine produced over the next 24 hours, including the urine from the specified time.

D. Cleanse around the meatus, discard the first portion of voiding, and collect the rest in a sterile bottle: This instruction is not appropriate for a 24-hour urine collection. It describes a procedure for collecting a clean-catch urine sample, which is different from a 24-hour urine collection for creatinine clearance.
