During a nap, a 3-year-old hospitalized child wets the bed. How should the nurse respond?

Correct Answer: C

Rationale: When a 3-year-old hospitalized child wets the bed during a nap, the nurse should respond by changing the child's clothes without discussing the incident. This approach helps to maintain the child's dignity, avoid embarrassment, and reduce anxiety related to bedwetting. Asking the child to help with remaking the bed (Choice A) may not be appropriate as it could cause unnecessary distress. Putting clean sheets on the bed over a rubber sheet (Choice B) addresses the aftermath but does not directly address the child's needs. Explaining that children should call the nurse when they need to go to the bathroom (Choice D) may not be effective in this immediate situation of bedwetting during a nap.

Correct Answer: D

Rationale: Maintaining NPO (nothing by mouth) status is essential before surgery for a patient with Hirschsprung disease to prevent aspiration. Administering antibiotics, ensuring bowel rest, and performing regular enemas are not the priority interventions before surgery for this condition. Administering antibiotics may be necessary in the postoperative period to prevent infection, ensuring bowel rest can be beneficial but is not the priority, and performing regular enemas is not typically recommended before surgery for Hirschsprung disease.

Correct Answer: B

Rationale: Ensuring adequate hydration is crucial during a vaso-occlusive crisis in sickle cell anemia as it helps to reduce the viscosity of the blood and prevent further sickling of the cells. While administering oxygen may be necessary in some cases, ensuring hydration takes precedence as it directly impacts the underlying pathophysiology of the crisis. Monitoring vital signs is important for ongoing assessment but does not directly address the crisis as hydration does. Administering pain medication is important for pain relief but does not address the primary issue of vaso-occlusion and is not the most crucial intervention in this scenario.

Correct Answer: B

Rationale: The sweat chloride test is the gold standard diagnostic test for cystic fibrosis as it measures the concentration of chloride in sweat. In cystic fibrosis, there is an abnormal transport of chloride across epithelial membranes, leading to elevated sweat chloride levels. A chest X-ray may show characteristic changes in the lungs associated with cystic fibrosis, but it is not a definitive diagnostic test. Pulmonary function tests assess lung function but do not specifically diagnose cystic fibrosis. Sputum culture may identify respiratory infections but does not confirm the diagnosis of cystic fibrosis.

Correct Answer: A

Rationale: Administering a bronchodilator is the priority intervention for a child experiencing an acute asthma exacerbation. Bronchodilators help to dilate the airways, making breathing easier and relieving acute symptoms of asthma. Antihistamines are not the first-line treatment for asthma exacerbations; they are more commonly used for allergic reactions. Corticosteroids are beneficial in reducing inflammation in asthma but are usually administered after bronchodilators to provide long-term control. Oxygen therapy may be necessary in severe cases of asthma exacerbation, but bronchodilators take precedence in improving airway patency and respiratory distress.
