Correct Answer: D

Rationale: Initiating pain assessment with a standardized pain scale is crucial in managing pain effectively during a sickle cell crisis. This step allows the nurse to objectively evaluate the child's pain level and tailor the pain management plan accordingly. Administering medication without a proper assessment could lead to inappropriate pain management. Using guided imagery and therapeutic touch may be beneficial as adjunct therapies but should not replace the initial pain assessment. Meperidine is not typically the first-line choice for pain management in sickle cell crisis due to its potential for neurotoxic metabolites.

Correct Answer: A

Rationale: In this scenario, the most appropriate intervention to prevent further injury is to raise the bed's side rails when a caregiver is not present. This measure helps in preventing falls without the need for constant supervision. Choice B is not practical as continuous caregiver presence may not always be feasible. Choice C is unsafe as loose restraints can pose a strangulation risk. Choice D does not address the need for intervention when a caregiver is absent, potentially leading to an increased risk of falls.

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.

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: A

Rationale: Infection is the greatest risk for an infant with exstrophy of the bladder due to the exposure of the bladder and surrounding tissues. The exposed bladder increases the risk of infection as it lacks the protective covering of the skin. Dehydration (Choice B) may occur but is not the greatest risk compared to infection. Urinary retention (Choice C) is less likely due to the nature of the condition. Intestinal obstruction (Choice D) is not directly associated with exstrophy of the bladder.
