Correct Answer: D

Rationale: Toddlers subjected to prolonged hospitalization with limited parental visits usually exhibit a limited emotional response to the environment. This behavior can be a coping mechanism for the child in dealing with the separation from their primary caregivers. The child might not show the same level of engagement or emotional expression as they would if their parents were present. Choices A, B, and C are less likely because the child's emotional response is typically more subdued and withdrawn in such circumstances, rather than being cheerful, consistently sad, or excessively crying.

Correct Answer: D

Rationale: Rapid acting insulin will help lower the elevated blood glucose level quickly.

Correct Answer: A

Rationale: The correct answer is A. Reading stories to the child about famous athletes would be the most successful guidance for a child with a 'slow-to-warm-up' temperament. This approach allows for a less active and more acceptable way of engaging with the child, aligning better with the child's temperament. Choices B, C, and D involve more active and potentially overwhelming activities for a child with such a temperament, which may not be as effective in stimulating and engaging the child.

Correct Answer: A

Rationale: The priority nursing intervention for a child with cystic fibrosis is administering pancreatic enzymes. This is crucial for managing the condition as it helps in proper digestion of nutrients. Providing respiratory therapy and encouraging physical activity are important aspects of care for cystic fibrosis, but administering pancreatic enzymes takes precedence due to its direct impact on the child's ability to digest and absorb essential nutrients. Encouraging frequent handwashing is a good practice for infection control but is not the priority intervention in this scenario.

Correct Answer: C

Rationale: After surgery for hypertrophic pyloric stenosis (HPS), it is appropriate to resume regular formula feeding within 24 hours postoperatively to promote recovery. Choice A, thickened formula after surgery, may be too heavy for the infant's digestive system at this early stage. Withholding feedings for the first 24 hours (Choice B) is not recommended as early feeding helps with recovery. Additional glucose feedings (Choice D) are not necessary and may not provide the balanced nutrition required after surgery.
