A nurse is caring for a child who has Kawasaki disease. Which of the following systems should the nurse monitor in response to this diagnosis?

A. Broth: While broth can be a source of fluids, it does not contain the appropriate balance of electrolytes needed to rehydrate the body effectively. Gastroenteritis can cause significant fluid and electrolyte loss, so an oral rehydration solution (ORS) with the right proportions of salts and sugars is essential to replace these losses adequately.
B. Diluted apple juice: Diluted apple juice may not provide the proper electrolyte balance needed for rehydration in cases of gastroenteritis. In fact, apple juice is not recommended during episodes of acute gastroenteritis, as it can worsen diarrhea due to its high sugar content. This can lead to further dehydration and discomfort.
C. Oral rehydration solution (ORS): This is the correct answer. Oral rehydration solution is specifically designed to replace lost fluids and electrolytes in cases of gastroenteritis. It contains the right balance of salts and sugars to facilitate effective absorption in the intestines and help rehydrate the body. ORS is the recommended fluid for managing dehydration caused by gastroenteritis in children.
D. Water: While water is essential for hydration, it is not enough to effectively treat dehydration caused by gastroenteritis. Plain water does not contain the necessary electrolytes like sodium, potassium, and chloride, which are lost during episodes of diarrhea and vomiting. Giving water alone may not adequately rehydrate the child and could potentially worsen the dehydration.

Following a cardiac catheterization, the nurse should provide the parent with appropriate discharge instructions to ensure the child's proper recovery. The correct instruction to include is option B: "Give the child acetaminophen for discomfort."

Explanation:

Option A: Offering the child clear liquids for the first 24 hours is not a typical instruction following a cardiac catheterization. After the procedure, the child may be allowed to resume a regular diet, as tolerated, based on the healthcare provider's orders.

Option B: This is the correct instruction. After cardiac catheterization, the child may experience some discomfort at the insertion site or the area where the catheter was threaded through the blood vessels. Acetaminophen can be used to manage mild pain or discomfort.

Option C: Taking a tub bath for the first 3 days is not typically mentioned in discharge instructions after a cardiac catheterization. The nurse might advise the parent to avoid submerging the catheter insertion site in water for a specific period and instead use sponge baths until permitted by the healthcare provider.

Option D: Keeping the child home for 1 week is not a standard recommendation for a cardiac catheterization. The recovery period after a cardiac catheterization is usually shorter, and the child can often resume normal activities within a day or two, depending on the specific circumstances of the procedure and the child's condition.

The nurse should thoroughly review the specific discharge instructions provided by the healthcare provider and ensure the parent understands the care required at home, including any restrictions on activities or signs of potential complications that require immediate attention.
