A nurse is preparing to remove an IV catheter from the arm of a client who has phlebitis at a peripheral IV site.
Which of the following actions should the nurse plan to take?

Choice A rationale:

A heart rate of 140/min is not a specific indicator of desmopressin effectiveness in a child with diabetes insipidus. The effectiveness of desmopressin is primarily evaluated based on the reduction in excessive urination and thirst associated with the condition. Monitoring heart rate is essential in certain situations but is not a direct measure of desmopressin efficacy in managing diabetes insipidus.

Choice B rationale:

Cessation of nocturnal enuresis (bedwetting) is a significant indication that desmopressin, an antidiuretic hormone, is effective. One of the main symptoms of diabetes insipidus is excessive urination, including during the night, leading to bedwetting. When desmopressin effectively reduces urine production, patients often experience improvement in these symptoms, including the cessation of nocturnal enuresis.

Choice C rationale:

Capillary refill of 3 seconds is a measurement used to assess peripheral perfusion and circulatory status. While it is essential to monitor capillary refill in pediatric patients, especially in cases of dehydration or circulatory compromise, it is not a specific indicator of desmopressin effectiveness in managing diabetes insipidus. Capillary refill time is more relevant in the assessment of cardiovascular function and fluid status.

Choice D rationale:

The absence of hypoglycemic episodes is not a direct indicator of desmopressin effectiveness. Diabetes insipidus is unrelated to blood glucose levels, as it involves the dysregulation of water balance due to insufficient antidiuretic hormone. While it is essential to monitor blood glucose levels in patients with diabetes mellitus, it is not relevant to assessing the effectiveness of desmopressin in treating diabetes insipidus.

The correct answer is Choice B: Assign the child to a negative air pressure room.

Choice A rationale: Assessing the child for Koplik spots is not appropriate in this situation because Koplik spots are associated with measles, not varicella. Koplik spots are small, white, irregular lesions that appear on the buccal mucosa during the prodromal phase of measles. They do not present in cases of varicella, which is characterized by a pruritic, vesicular rash.

Choice B rationale: Assigning the child to a negative air pressure room is the most suitable action because varicella is highly contagious and can be transmitted through airborne particles. A negative air pressure room helps to contain these particles and minimize the risk of infection transmission to other patients, healthcare workers, and visitors. Airborne precautions are the recommended infection control measures for managing varicella cases in healthcare settings.

Choice C rationale: Utilizing droplet precautions alone is insufficient for managing varicella because the virus can also be spread through airborne particles. While droplet precautions may be a component of the overall infection control strategy, they are inadequate without the additional implementation of airborne precautions, such as a negative air pressure room.

Choice D rationale: Administering aspirin to a child with a viral illness is generally contraindicated due to the potential risk of Reye's syndrome, a rare but severe condition characterized by liver failure and encephalopathy. It is essential to follow appropriate guidelines for managing fever and discomfort in pediatric patients with varicella, which typically involve using acetaminophen or ibuprofen instead of aspirin.
