Answer to Question 1

Correct Answer: 1

Antihistamines alleviate the systemic effects of histamine such as urticaria and angioedema. They are also useful in relieving allergic rhinitis, drying respiratory secretions through an anticholinergic effect. The preferred route of administration is oral, and side effects include drowsiness and dry mouth. The patient experiencing an allergic response to ragweed will not be prescribed an antibiotic, antiviral, or antifungal medication.

Answer to Question 2

Correct Answer: 1

The appearance of a wheal and erythema, with a wheal diameter at least 5 mm larger than that produced by the control, indicates a positive response in an intradermal skin test. A localized itchy wheal would be a positive response for a prick test. Papules and ulceration would be a positive response for a patch test.
