When caring for the child with Kawasaki disease, the nurse should understand what principle of care?

The correct answers are choices B. Administer Benadryl, and D. Apply a cool compress.

Choice A rationale:

Placing an ace wrap on the bite is not recommended for a brown recluse spider bite. This action could potentially worsen the situation as it might trap venom in the area and increase the risk of necrosis.

Choice B rationale:

Administering Benadryl is a suitable action for alleviating pain and managing allergic reactions related to the bite. Benadryl (diphenhydramine) is an antihistamine that can help reduce itching and inflammation.

Choice C rationale:

Elevating the affected area might not provide significant pain relief for a brown recluse spider bite. Elevating is generally more effective for reducing swelling associated with injuries involving fluid accumulation, like sprains or strains.

Choice D rationale:

Applying a cool compress to the bite area can help alleviate pain and reduce inflammation. Cold therapy constricts blood vessels, which can reduce swelling and numb the area, providing relief.

The correct answer is choice C: Oral rehydration solution (ORS).

Choice A rationale:

Clear liquids, 1 to 2 ounces at a time, might not be sufficient to adequately rehydrate a child with severe dehydration. Clear liquids lack the necessary electrolytes and glucose content to effectively combat dehydration and replace lost fluids.

Choice B rationale:

Administration of antidiarrheal medication is not the initial step in managing severe dehydration caused by acute diarrhea and vomiting. Antidiarrheal medications can slow down the gastrointestinal motility, which may exacerbate the problem by delaying the elimination of the causative agent and prolonging the dehydration.

Choice C rationale:

Oral rehydration solution (ORS) is the recommended initial intervention for managing severe dehydration caused by acute diarrhea and vomiting. ORS contains the appropriate balance of electrolytes (sodium, potassium, chloride) and glucose to replace lost fluids and electrolytes, thereby helping to rehydrate the child effectively. It is absorbed even when digestion is impaired due to the illness.

Choice D rationale:

Intravenous fluids might be necessary if the child's condition is very severe and oral intake cannot be maintained. However, it's not the first-line intervention. Oral rehydration is preferred whenever feasible because it is less invasive and can be administered even in mild to moderate dehydration cases.
