A child with a diagnosis of pyloric stenosis is scheduled for surgery. What preoperative intervention is important for the nurse to perform?

Correct Answer: C

Rationale: The correct preoperative intervention for a child with pyloric stenosis is to monitor for signs of dehydration. Pyloric stenosis involves the obstruction of the pyloric sphincter, leading to projectile vomiting, which can result in dehydration and electrolyte imbalances. Monitoring for signs of dehydration is crucial to assess the child's fluid status and prevent complications. Administering intravenous fluids, although important in managing dehydration, is not typically a preoperative intervention but rather a treatment during or after surgery. Monitoring for signs of infection and pain may also be important but are not the priority preoperative interventions in a child with pyloric stenosis.

Correct Answer: B

Rationale: The most important nursing intervention for a child with bronchiolitis is providing respiratory therapy. This intervention helps to maintain airway patency and improve breathing by assisting with mucus clearance and ventilation. Administering bronchodilators (Choice A) may be considered in some cases, but it is not the most crucial intervention for bronchiolitis. Monitoring oxygen saturation (Choice C) is important but is not as directly impactful as providing respiratory therapy. Encouraging fluid intake (Choice D) is important for hydration but does not directly address the respiratory distress associated with bronchiolitis.

Correct Answer: D

Rationale: The correct preoperative intervention for a child with appendicitis scheduled for surgery is to monitor for signs of infection. This is crucial to ensure that any potential infections are promptly identified and managed before surgery. Administering antibiotics, maintaining strict NPO status, and encouraging fluid intake are important interventions in various clinical situations but are not the priority in this scenario. Administering antibiotics may be part of the treatment plan but is typically prescribed by a physician. Maintaining NPO status is important to prevent complications related to anesthesia but may not directly address the specific needs of a child with appendicitis. Encouraging fluid intake is generally beneficial for hydration but may not be the primary concern before surgery for appendicitis.

Correct Answer: A

Rationale: Checking blood glucose levels before meals and at bedtime is essential for managing type 1 diabetes mellitus. This timing helps in assessing the effectiveness of insulin therapy, making adjustments to insulin doses, and preventing hyperglycemia and hypoglycemia. Option B is incorrect because it focuses on the method of obtaining blood samples rather than the timing of monitoring. Option C is incorrect as urine test strips are not recommended for accurate blood glucose monitoring in type 1 diabetes. Option D, recognizing signs of hypoglycemia, is important but not the primary emphasis when teaching about blood glucose monitoring.

Correct Answer: B

Rationale: During a vaso-occlusive crisis in sickle cell anemia, the priority nursing intervention is administering pain medication. Pain management is crucial to alleviate the intense pain experienced by the child. While administering oxygen can help improve oxygenation, it is not the most critical intervention during a vaso-occlusive crisis. Monitoring fluid intake is important for overall care but is not the immediate priority during a crisis. Encouraging physical activity is contraindicated during a vaso-occlusive crisis as it can worsen the pain and the crisis itself.
