Exophthalmos may occur in children with what diagnosis?

The correct answer is choice C. After taking antibiotics for 24 hours.

Choice A rationale:

Returning to school if no complications develop is not a sufficient guideline for allowing a child with streptococcal pharyngitis to return to school. Streptococcal pharyngitis (strep throat) is highly contagious, and children should be treated with antibiotics to prevent the spread of the infection.

Choice B rationale:

Waiting until the sore throat is better is not a specific enough criterion for returning to school. While the resolution of symptoms is an important factor, it's crucial to ensure that the child has also been on antibiotics for an appropriate duration to reduce the risk of spreading the infection to others.

Choice C rationale:

The recommended guideline is to return to school after taking antibiotics for 24 hours. This timeframe helps ensure that the child's contagiousness is significantly reduced, minimizing the risk of transmitting the infection to classmates and school staff.

Choice D rationale:

Waiting for three days after taking antibiotics is not as precise as waiting for 24 hours. With proper antibiotic treatment, the child's contagiousness decreases rapidly, and waiting for three days might be unnecessary and could potentially result in more missed school days than needed.

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.
