A patient at sports camp is complaining of itchy and watery eyes, coughing, and sneezing when outdoors. The patient's chart states that he has an allergy to grasses. Which medication will the nurse administer?
a. Antitussive
b. Expectorant
c. Antihistamine
d. Decongestant
ANS: C
Antihistamines are used for inflammation and swelling resulting from the release of histamine during an antigen-antibody reaction. A grass allergy means that the patient experiences a release of histamine (antibody reaction) when exposed to the antigen, grass. Antitussive medications are for relief of cough. Expectorants are for the loosening of mucus so the patient can expel it by coughing. Decongestants would not help these symptoms as much as antihistamines.
