Answer to Question 1

Correct Answer: 1

If symptoms improve after an elimination diet, foods are reintroduced one at a time until symptoms recur, indicating allergy to that food. The patient should not resume the pre-elimination diet, take an antihistamine prior to eating a food identified as causing an allergy, or consume foods known to cause an allergic response.

Answer to Question 2

Correct Answer: 1

A patch test assesses a one-inch area impregnated with the allergen and is applied for 48 hours. Absence of a response indicates a negative result. Positive responses are graded from mild erythema in the exposed area to severe papules, vesicles, or ulcerations. The Coombs' indirect test checks the recipient's and donor's blood for antibodies before a blood transfusion. The normal range of the eosinophil count is 14. There is not enough information about the elevated hematocrit level.
