A patient is experiencing symptoms of exposure to environmental ragweed. The nurse should instruct the patient on the use of which medication?
1. antihistamines
2. antibiotics
3. antiviral medications
4. antifungal medications
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.
