The nurse is working with a group of chronically ill school-aged children and their caregivers. Which strategy would be most effective in helping the children reach their self-care treatment goals?

Choice A reason: Cartilage is a connective tissue, not stored in bones, which house minerals like calcium. Minerals are critical for bone strength, making this incorrect, as it misidentifies the substances stored in the musculoskeletal system in the nurse’s understanding of bone physiology.

Choice B reason: Vitamins, like vitamin D, are stored in tissues, not bones, which store minerals for structural integrity. Minerals are the primary storage component, making this incorrect, as it does not reflect the physiological role of bones in the nurse’s musculoskeletal knowledge.

Choice C reason: Spinal fluid is contained in the central nervous system, not stored in bones, which hold minerals. Minerals support bone function, making this incorrect, as it confuses bone physiology with unrelated systems in the nurse’s understanding of the musculoskeletal system.

Choice D reason: Bones store minerals like calcium and phosphorus, essential for strength and metabolic functions. This aligns with musculoskeletal physiology, making it the correct answer for the nurse’s recognition of what is stored in bones as part of their anatomical knowledge.

Choice A reason: Intravenous administration isn’t inherently safer, as it carries risks like infection or extravasation. Less trauma from fewer injections is accurate, making this incorrect, as it overstates safety compared to the true benefit of reduced physical and emotional trauma in pediatric IV medication delivery.

Choice B reason: Intravenous medication reduces the need for multiple injections, minimizing physical and emotional trauma for children. This aligns with pediatric nursing principles for patient comfort, making it the correct statement about the advantage of IV administration compared to repeated intramuscular or subcutaneous injections.

Choice C reason: IV medications are absorbed rapidly, not slowly, due to direct bloodstream delivery. Less trauma from fewer injections is the true benefit, making this incorrect, as it misrepresents the pharmacokinetics of intravenous administration in the context of pediatric medication delivery.

Choice D reason: IV medication is delivered into veins, not fatty tissue, which describes subcutaneous injections. Reduced trauma from fewer injections is accurate, making this incorrect, as it confuses IV administration with another route in the nurse’s understanding of medication delivery methods.
