When palpating the child's cervical lymph nodes, the nurse notes that they are tender, enlarged, and warm. The best explanation for this is:.

The correct answer is choice D. Give small amounts of favorite fluids frequently to prevent dehydration.

Choice A rationale:

Having the child wear heavy clothing to prevent chilling is not an appropriate nursing intervention for an infant with an elevated temperature. Infants are more susceptible to temperature regulation issues, and heavy clothing could exacerbate their discomfort and potentially raise their body temperature further.

Choice B rationale:

Giving tepid water baths to reduce fever is not recommended for fever management in infants. Tepid baths might cause discomfort and shivering, which could lead to increased heat production and potential elevation of body temperature.

Choice C rationale:

Encouraging food intake to maintain caloric needs is important, but it might not be well-tolerated by an infant with an elevated temperature and upper respiratory tract infection. Infants often have reduced appetite during illness.

Choice D rationale:

Giving small amounts of favorite fluids frequently to prevent dehydration is an appropriate nursing intervention. Fever and elevated temperature can lead to increased fluid loss through sweating and increased respiratory rate. Offering small, frequent fluid intake helps maintain hydration and prevent dehydration. Using favorite fluids can also encourage the child to drink more.

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.
