A nurse is teaching a client who is trying to conceive.
Which of the following should the nurse instruct the client to increase in her diet to prevent a neural tube defect?

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 B.

Choice A reason: Avoid preparing medications for more than two clients at one time is a guideline aimed at reducing the risk of medication errors. However, it is not an absolute rule and may vary depending on the setting and resources available.

Choice B reason: Inform clients about the action of each medication prior to administration. This practice is essential for patient education, ensuring that patients are informed about what medications they are taking and why, which can improve adherence and outcomes.

Choice C reason: Reading medication labels at least two times prior to administration is a good practice to avoid errors, but it is not always specified as a standard requirement in medication administration guidelines.

Choice D reason: Completing an incident report if a client vomits after taking a medication is necessary only if the vomiting is related to an adverse drug reaction or a medication error, not for routine vomiting.
