Calcium carbonate is given with meals to a child with chronic renal disease. The purpose of this is to achieve which desired result?
Bind phosphorus.
Increase absorption of fat-soluble vitamins.
Stimulate appetite.
Prevent vomiting.
The Correct Answer is A
Choice A rationale:
Calcium carbonate is often given with meals to individuals with chronic renal disease, especially those on dialysis. One of the primary purposes is to bind dietary phosphorus in the gastrointestinal tract. In chronic renal disease, the kidneys are less effective at filtering out excess phosphorus from the blood, leading to elevated phosphorus levels (hyperphosphatemia). Elevated phosphorus levels can contribute to bone and mineral disorders in these patients. Calcium carbonate forms insoluble calcium phosphate complexes with dietary phosphorus, preventing its absorption and facilitating its elimination from the body through the feces.
Choice B rationale:
While calcium carbonate can interact with fat-soluble vitamins like vitamin D, the primary reason for administering it to individuals with chronic renal disease is to manage phosphorus levels. Calcium carbonate can bind phosphorus and prevent its absorption, which is particularly important for patients with compromised kidney function.
Choice C rationale:
Stimulating appetite is not a primary purpose of administering calcium carbonate to children with chronic renal disease. The main focus is on managing phosphorus levels and preventing complications associated with hyperphosphatemia.
Choice D rationale:
Preventing vomiting is not a primary purpose of giving calcium carbonate to children with chronic renal disease. Calcium carbonate is typically used to manage phosphorus levels and complications related to hyperphosphatemia in this population.

Correct Answer is C
Explanation
The correct answer is choice C: Administering penicillin.
Choice A rationale:
Imposing strict bed rest for 4 to 6 weeks. This choice is not the most appropriate therapeutic management for rheumatic fever. While rest is important during the acute phase, strict bed rest for 4 to 6 weeks is excessive and could lead to physical deconditioning and psychological distress for the child.
Choice B rationale:
Administering corticosteroids if chorea develops. This choice is relevant to the management of rheumatic fever but is not the primary treatment. Chorea is a movement disorder that can occur as a complication of rheumatic fever. Corticosteroids may be used to manage chorea symptoms, but they are not the mainstay of treatment for rheumatic fever itself.
Choice C rationale:
Administering penicillin. This is the correct choice. Penicillin is the mainstay of treatment for rheumatic fever. It helps eradicate the group A streptococcal infection that triggers the inflammatory response leading to rheumatic fever. Penicillin is essential to prevent further complications such as rheumatic heart disease.
Choice D rationale:
Avoiding salicylates (aspirin). This choice is also relevant to the management of rheumatic fever. Salicylates, including aspirin, are used to relieve symptoms and reduce inflammation. However, in children with acute rheumatic fever, salicylates are contraindicated due to the risk of developing Reye's syndrome, a serious condition that affects the brain and liver.
Correct Answer is D
Explanation
The correct answer is choice D: Verbalizing the importance of monitoring for medication side effects.
Choice A rationale:
Allowing the adolescent to make decisions about whether or not to take medication is important, but it is not the priority nursing goal for a 14-year-old diagnosed with Graves' disease. The priority is ensuring proper medication management and monitoring to control the thyroid dysfunction and prevent potential complications.
Choice B rationale:
Relieving constipation might be a consideration, but it is not the priority nursing goal for a 14-year-old diagnosed with Graves' disease. The primary focus is on addressing the thyroid-related issues and providing appropriate education and support to the adolescent.
Choice C rationale:
Developing alternative educational goals is not the priority nursing goal for a 14-year-old diagnosed with Graves' disease. While education is important, the immediate concern is managing the medical condition and ensuring the adolescent's well-being.
Choice D rationale:
Verbalizing the importance of monitoring for medication side effects is the priority nursing goal for a 14-year-old diagnosed with Graves' disease. Graves' disease is a thyroid disorder that requires medication management, typically involving antithyroid medications or other interventions. Monitoring for medication side effects ensures the adolescent's safety and helps to prevent adverse reactions or complications. It also empowers the adolescent to be vigilant about their health and medication regimen.
