A nurse is caring for a client whose child died from cancer.
The client states, "It's hard to go on without him." Which of the following questions should the nurse ask the client first?

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.

Choice A rationale:

A client who received a Mantoux test 48 hr ago and has an induration does not require immediate follow-up care. An induration at the injection site indicates a positive reaction, but further evaluation and management are necessary, not urgent.

Choice B rationale:

A client taking warfarin with an INR of 1.8 requires follow-up care. The normal range for INR in a client taking warfarin is usually 2.0 to 3.0. An INR of 1.8 suggests inadequate anticoagulation, putting the client at risk of thromboembolic events. Dose adjustment or other interventions are needed to bring the INR within the therapeutic range.

Choice C rationale:

A client scheduled for a colonoscopy and taking sodium phosphate does not necessarily require immediate follow-up care. However, sodium phosphate can cause electrolyte imbalances, so monitoring for any signs of electrolyte disturbances is essential, but it does not mandate urgent intervention.

Choice D rationale:

A client taking bumetanide with a potassium level of 3.6 mEq/L requires follow-up care. The normal range for potassium is typically 3.5 to 5.0 mEq/L. A potassium level below the normal range (hypokalemia) can lead to cardiac arrhythmias and muscle weakness. The client may need potassium supplements or dietary adjustments to correct the imbalance.
