Correct Answer: D

Rationale: Retractions and the use of accessory respiratory muscles are signs of respiratory distress in infants. These clinical manifestations can be associated with trauma, such as shaken baby syndrome (SBS), which can lead to severe head injuries and respiratory compromise. Birth before 32 weeks' gestation (Choice A) is more related to prematurity complications rather than SBS. The absence of stridor and adventitious breath sounds (Choice B) may not be specific indicators of SBS. Previous episodes of apnea lasting 10 to 15 seconds (Choice C) alone may not be as concerning as the presence of retractions and use of accessory muscles in the context of a distressed infant.

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: 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: A

Rationale: The correct recommendation to reduce the risk of SIDS in infants is to place them on their back to sleep. This sleeping position helps prevent the occurrence of SIDS by maintaining an open airway and reducing the risk of suffocation. Using a pacifier during sleep has also shown some protective effect against SIDS, but it is not as effective as placing the infant on their back. Having the infant sleep on their side is not recommended as it can increase the risk of accidental suffocation. Keeping the infant's room cool does not directly reduce the risk of SIDS.

Correct Answer: B

Rationale: In atopic dermatitis, the nurse would expect to observe a dry, red, scaly rash with lichenification. Lichenification is thickened skin due to chronic scratching. Choices A, C, and D are incorrect. Erythematous papulovesicular rash is more characteristic of contact dermatitis, pustular vesicles with honey-colored exudates are seen in impetigo, and hypopigmented oval scaly lesions are typical of pityriasis alba.
