A child is brought to the emergency department experiencing an anaphylactic reaction to a bee sting. While an airway is being established, what medication should the nurse prepare for immediate administration?
Diphenhydramine.
Epinephrine.
Dopamine.
Calcium chloride.
The Correct Answer is B
The correct answer is choice B. Epinephrine.
Choice A rationale:
Diphenhydramine. Diphenhydramine is an antihistamine commonly used to relieve allergic symptoms such as itching, rash, and runny nose. While it can be part of the treatment for anaphylactic reactions, it is not the medication of choice for immediate administration in the case of a severe anaphylactic reaction like the one described in the scenario.
Choice B rationale:
Epinephrine. Correct Answer. In cases of severe anaphylactic reactions, epinephrine (adrenaline) is the medication of choice for immediate administration. Epinephrine acts rapidly to reverse life-threatening symptoms, such as airway constriction, low blood pressure, and hives. It works by dilating airways, increasing heart rate, and improving blood pressure.
Choice C rationale:
Dopamine. Dopamine is a medication used to increase blood pressure and cardiac output in certain critical situations. However, it is not the first-line treatment for anaphylactic reactions. Epinephrine's effects on airway and cardiovascular function make it the preferred choice in this context.
Choice D rationale:
Calcium chloride. Calcium chloride is not the appropriate medication for treating anaphylactic reactions. Its main medical uses include treating hypocalcemia (low blood calcium levels) and certain cardiac arrhythmias. It does not address the primary symptoms and physiological changes associated with anaphylaxis.

Correct Answer is A
Explanation
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).
