In understanding the physiology of the musculoskeletal system, the nurse recognizes that which of the following are stored in the bones?

Cartilage.

Vitamins.

Spinal fluid.

Minerals.

Answer and Explanation

The Correct Answer is D

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.

Correct Answer is D

Explanation

Choice A reason: Increasing protein calories doesn’t address malabsorption causing constipation and diarrhea in cystic fibrosis. Pancreatic enzymes improve nutrient absorption, making this irrelevant and incorrect compared to the need to correct digestive issues due to enzyme deficiency in the child’s dietary management.

Choice B reason: Saturated fat doesn’t resolve malabsorption-related constipation and diarrhea in cystic fibrosis and may worsen symptoms. Pancreatic enzymes correct enzyme deficiency, making this inappropriate and incorrect compared to the dietary adjustment needed to manage the child’s gastrointestinal symptoms effectively.

Choice C reason: Iodized salt supports hydration in cystic fibrosis but doesn’t address malabsorption causing diarrhea and constipation. Pancreatic enzymes target digestive issues, making this incorrect, as it fails to correct the underlying enzyme deficiency responsible for the child’s gastrointestinal symptoms.

Choice D reason: Pancreatic enzymes improve fat and nutrient absorption in cystic fibrosis, reducing constipation and diarrhea due to malabsorption. This aligns with pediatric cystic fibrosis management, making it the correct substance to increase in the child’s diet to address the reported gastrointestinal symptoms.

A. Walk backwards with heel to toe B. Hop on one foot C. Ride a bicycle D. Jump rope

Correct Answer is B

Explanation

Choice A reason: Walking backwards heel-to-toe requires advanced balance typically mastered closer to age 5 or 6. A 4-year-old can hop on one foot, a gross motor skill achievable by this age, making this too complex and incorrect for the preschooler’s developmental stage during the assessment.

Choice B reason: Hopping on one foot is a gross motor skill typically mastered by age 4, reflecting balance and coordination development. This aligns with pediatric developmental milestones, making it the correct activity a 4-year-old preschooler can successfully accomplish during a well-child gross motor assessment.

Choice C reason: Riding a bicycle, especially without training wheels, is typically achieved around age 5-6, requiring advanced coordination. A 4-year-old can hop on one foot, making this too advanced and incorrect for the gross motor skills expected at this age in a well-child visit.

Choice D reason: Jumping rope demands complex coordination and strength, typically mastered after age 6. A 4-year-old can hop on one foot, a simpler skill, making this incorrect, as jump rope is beyond the gross motor capabilities of a preschooler at this developmental stage.
