Answer to Question 1

D
Epinephrine is the drug of choice for anaphylaxis.
Ephedrine is not a drug of choice in an anaphylaxis situation.
Diphenhydramine is an antihistamine and is indicated for minor allergic reactions, not evident in this patient, who is symptomatic of anaphylaxis.
Dopamine, which can be used to bring blood pressure up, would not reverse the signs and symp-toms of anaphylaxis.

Answer to Question 2

B
The nurse's best response is that azithromycin has fewer severe gastrointestinal (GI) side effects than erythromycin.
Calling the health care provider is not necessary, because it is not known whether the patient will experience nausea with the medication.
Azithromycin should not be taken with meals, because absorption is reduced by 50 in the presence of food.
Obtaining a prescription for an antiemetic is not necessary, because it is not known whether the patient will have any GI side effects; they occur in only 3 of those who take the drug.
