What is the most appropriate nursing diagnosis for a child diagnosed with moderate anemia?

The correct answer is choice C.

Choice C rationale:

Placing the avulsed tooth in cold milk is the most suitable medium for transporting it to the dentist. Cold milk helps preserve the viability of the tooth's cells and tissues, which is crucial for successful reimplantation. The temperature and composition of cold milk provide a suitable environment to prevent cell damage.

Choice A rationale:

Placing the tooth in a dry, clean jar is not recommended. A dry environment can cause the tooth's cells to dry out and become nonviable, making reimplantation less successful.

Choice B rationale:

Warm salt water is not the optimal choice for transporting an avulsed tooth. Warm water can cause damage to the tooth's cells, and salt water may not provide the necessary conditions to maintain the tooth's viability.

Choice D rationale:

Placing the tooth in cold water might seem logical, but it is not as effective as cold milk. Cold water lacks the protective properties and nutrients that milk provides, potentially leading to a higher risk of cell damage in the avulsed tooth.

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.
