Correct Answer: D

Rationale: After undergoing surgery for pectus excavatum correction with steel bar placement, the nurse should instruct the parents to avoid placing the child in a side-lying position. This position should be avoided to prevent displacement of the steel bar, which could compromise the surgical outcome. Semi-Fowler, supine, and high Fowler positions do not pose the same risk of displacing the steel bar and are generally safe and comfortable for the child in this postoperative period.

Correct Answer: D

Rationale: A low-phenylalanine diet is required for infants with PKU to prevent the buildup of phenylalanine, which can lead to brain damage.

Correct Answer: B

Rationale: The correct answer is to 'Apply topical corticosteroids as prescribed.' Atopic dermatitis is a condition characterized by inflammation and itchiness of the skin. Topical corticosteroids are commonly used to reduce inflammation and relieve symptoms in atopic dermatitis. Teaching the caregiver to apply the medication as prescribed by the healthcare provider is crucial for managing the child's condition effectively. Choices A, C, and D are not the priority discharge teaching for atopic dermatitis. While avoiding triggers that cause flare-ups and contact with sick individuals can be beneficial, the immediate focus should be on proper medication administration to address the underlying inflammation and symptoms of atopic dermatitis.

Correct Answer: A

Rationale: The correct answer is to advise the parents to avoid exposure to allergens. Asthma attacks are often triggered by allergens such as dust mites, pollen, pet dander, and mold. By minimizing the child's exposure to these triggers, the likelihood of asthma attacks can be reduced. Encouraging regular exercise is beneficial for overall health but may not directly prevent asthma attacks. Providing a high-protein diet and increasing fluid intake are important for general well-being but do not specifically address asthma prevention.

Correct Answer: D

Rationale: The correct answer is D. Novolin N insulin peaks in the evening, which can lead to hypoglycemia during the night. Providing an evening snack helps to counteract the late insulin activity and prevent hypoglycemia. Choice A is incorrect because the primary reason for the evening snack is not to encourage adherence to the diet. Choice B is incorrect as the snack is not primarily for immediate energy use. Choice C is incorrect as the goal of the snack is not to help the child gain weight but to manage blood sugar levels.
