Correct Answer: C

Rationale: Offering medical equipment to play with prior to a procedure is developmentally appropriate when caring for a hospitalized school-age child. Allowing the child to familiarize themselves with the equipment helps reduce fear and anxiety about the upcoming procedure. Choices A, B, and D are not as appropriate for a school-age child. Providing brochures regarding sexuality is not developmentally appropriate for this age group. Giving clear instructions about treatment details may overwhelm a child of this age. Using toys for distraction during a painful procedure is more suitable for younger children.

Correct Answer: B

Rationale: Starting the IV as planned while allowing the child to express feelings afterward helps build trust and ensures the timely administration of necessary antibiotics. Delaying the procedure or changing the route could compromise the child's treatment.

Correct Answer: C

Rationale: These symptoms are indicative of dehydration or water depletion, which is common in infants and can rapidly lead to severe consequences if not addressed promptly.
