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: C

Rationale: The correct answer is C. Needing assistance to climb stairs is considered expected behavior for an 18-month-old toddler. At this age, children are still developing their gross motor skills, coordination, and balance, which can vary in proficiency. It is common for toddlers to be able to crawl upstairs before mastering the skill of climbing stairs upright. Options A, B, and D are incorrect because at 18 months, it is normal for children to require help and practice with climbing stairs and does not necessarily point to any specific medical conditions or developmental issues.

Correct Answer: C

Rationale: The correct answer is C. The child's behavior of smiling easily, interacting happily with nurses, and showing disinterest in the parent when they visit indicates that the child has emotionally withdrawn and accepted the separation. This response suggests that the child may have given up fighting against the separation from the parent due to prolonged hospitalization. Choices A, B, and D are incorrect. Choice A about the child repressing feelings towards the parent is not supported by the scenario. Choice B about routines and feeling safe does not address the emotional aspect of the child's behavior. Choice D about improved behavior due to feeling better physically does not explain the emotional dynamics at play in the child's behavior.

Correct Answer: C

Rationale: The most appropriate response for the nurse is to emphasize the importance of consistency in discipline when dealing with toddlers. Toddlers are at a stage where they are exploring boundaries and learning what behaviors are acceptable. By being consistent, parents can help reinforce these boundaries and teach appropriate behaviors effectively. Choices A, B, and D do not provide specific guidance on how to address the discipline issue effectively. While acknowledging the challenges of this age (Choice A) and empathizing with the parents (Choice D) are important, the key point in this scenario is to highlight the significance of consistency in discipline (Choice C).

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.
