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. Sparse hair.
Choice A rationale:
Sleepiness is not a typical symptom of hypothyroidism. Hypothyroidism, a condition where the thyroid gland doesn't produce enough thyroid hormone, leads to a slower metabolism which can cause fatigue, but not necessarily sleepiness.
Choice B rationale:
Weight loss is not associated with hypothyroidism. In fact, weight gain is a common symptom due to the reduced metabolic rate caused by insufficient thyroid hormone levels.
Choice C rationale:
Sparse hair is a characteristic symptom of hypothyroidism. The thyroid hormones play a crucial role in the growth and maintenance of hair follicles. In hypothyroidism, hair can become brittle, thin, and sparse.
Choice D rationale:
Diarrhea is not a typical symptom of hypothyroidism. Constipation, on the other hand, is more commonly associated with this condition due to the slowed digestive processes caused by low thyroid hormone levels.
Choice E rationale:
Puffiness around the eyes is not typically associated with hypothyroidism. However, it is a symptom of another thyroid disorder known as Graves' disease, which is characterized by hyperthyroidism (overactive thyroid).
Correct Answer is D
Explanation
The correct answer is Choice D: Refer children with sore throats for throat cultures.
Choice A rationale:
Recommending salicylates instead of acetaminophen for minor discomforts is not relevant to the prevention of rheumatic fever. Rheumatic fever is primarily associated with untreated streptococcal infections, particularly streptococcal pharyngitis (strep throat), which can lead to complications such as rheumatic fever if left untreated. The choice of pain relievers like salicylates or acetaminophen doesn't play a significant role in preventing rheumatic fever.
Choice B rationale:
Encouraging routine cholesterol screenings is not relevant to the prevention of rheumatic fever. Rheumatic fever is an immune-mediated inflammatory response to certain strains of Streptococcus bacteria, particularly Streptococcus pyogenes. Cholesterol screenings are more related to assessing cardiovascular risk and are not directly linked to preventing rheumatic fever.
Choice C rationale:
Conducting routine blood pressure screenings is not directly related to the prevention of rheumatic fever. Blood pressure screenings are important for identifying hypertension and other cardiovascular risk factors, but they do not have a direct impact on preventing rheumatic fever, which is primarily a complication of untreated streptococcal infections.
Choice D rationale:
Refer children with sore throats for throat cultures. This is the correct choice. Rheumatic fever often develops as a result of untreated streptococcal pharyngitis (strep throat). Throat cultures are crucial for diagnosing streptococcal infections and determining the appropriate course of treatment with antibiotics. By identifying and treating streptococcal infections promptly, the risk of developing rheumatic fever can be significantly reduced.
