Correct Answer: B

Rationale: When an infant experiences intractable vomiting, it can lead to the loss of stomach acids, resulting in metabolic alkalosis. Alkalosis is characterized by elevated blood pH and can lead to serious complications. Assessing for alkalosis is essential in this scenario to monitor and manage the infant's condition. Choices A, C, and D are incorrect because in this context, the primary concern is the metabolic imbalance caused by excessive vomiting, leading to alkalosis rather than acidosis, hyperkalemia, or hypernatremia.

Correct Answer: C

Rationale: The correct preoperative intervention for a child with pyloric stenosis is to monitor for signs of dehydration. Pyloric stenosis can lead to vomiting, which can result in dehydration. Monitoring for signs of dehydration is crucial to ensure the child's fluid balance is maintained. Administering intravenous fluids, although important for managing dehydration and electrolyte imbalances, would typically be done postoperatively rather than as a preoperative intervention. Monitoring for signs of infection is important but not specific to the preoperative period for pyloric stenosis. Monitoring for signs of pain is also important but may not be the most critical preoperative intervention in this scenario.

Correct Answer: B

Rationale: Correct! When a child is being discharged after treatment for dehydration, it is important to educate caregivers about monitoring for signs of dehydration to prevent reoccurrence. Dehydration is the primary concern in this scenario, as the child's fluid levels need to be closely monitored. Choices A, C, and D are incorrect because while infection, hypovolemia, and malnutrition are also important considerations in pediatric care, the immediate focus after treating dehydration should be on preventing its recurrence by monitoring for signs of dehydration.

Correct Answer: A

Rationale: The most important nursing intervention for a child with leukemia receiving chemotherapy is to monitor for signs of infection. Chemotherapy suppresses the immune system, putting the child at a higher risk of developing infections. Early detection and prompt treatment of infections are crucial to prevent complications and improve outcomes. Monitoring for signs of bleeding (choice B), dehydration (choice C), and pain (choice D) are also important aspects of care, but in this scenario, the priority is to prevent and manage infections due to the compromised immune system.

Correct Answer: B

Rationale: Limiting screen time is a crucial recommendation to prevent childhood obesity. Excessive screen time is associated with sedentary behavior and increased consumption of unhealthy snacks, leading to weight gain. Encouraging high-calorie snacks (Choice A) contradicts the goal of preventing obesity. While fast food as a treat (Choice C) can be consumed occasionally, it should not be encouraged as a regular practice. Allowing the child to eat freely (Choice D) without restrictions can lead to overeating and unhealthy dietary habits, contributing to obesity risk.
