A nurse is assessing a 5-year-old child who has diabetes insipidus and is receiving desmopressin.
Which of the following findings should the nurse identify as an indication that the medication is effective?
Heart rate 140/min.
Cessation of nocturnal enuresis.
Capillary refill 3 seconds.
Absence of hypoglycemic episodes.
The Correct Answer is B
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.

Correct Answer is C
Explanation
The correct answer is c. Use an albuterol inhaler.
Choice A reason: Eating a meal before postural drainage is not recommended because it can cause discomfort, nausea, or vomiting due to the positions required for the procedure.
Choice B reason: Taking pancrelipase is important for aiding digestion in cystic fibrosis patients, but it is not specifically related to the preparation for postural drainage.
Choice C reason: Bronchodilators like albuterol are used before airway clearance techniques to open the airways, making it easier to clear mucus during postural drainage.
Choice D reason: While maintaining oral hygiene is important for overall health, it is not a preparation step for postural drainage.
Correct Answer is A
Explanation
Choice A rationale:
Spotting is a common finding in placenta previa. It occurs due to the abnormal implantation of the placenta over or near the cervical os, leading to vaginal bleeding. This bleeding can range from mild spotting to severe hemorrhage and is a significant sign of placenta previa.
Choice B rationale:
Nausea is not a specific sign of placenta previa. Nausea and vomiting are common symptoms during early pregnancy but are not directly related to placenta previa.
Choice C rationale:
A board-like abdomen is a sign of peritonitis or an acute abdomen, which is not associated with placenta previa. This finding suggests intra-abdominal inflammation and is unrelated to the condition in question.
Choice D rationale:
Delayed menses is a common sign of pregnancy, but it does not specifically indicate placenta previa. Placenta previa is characterized by vaginal bleeding, which is not synonymous with a delay in menstrual periods.
