The nurse teaches the client that the major disadvantage of antitussive therapy on Robitussin A-C is that:
Correct answer
A
Rationale
The correct answer is A. Antitussive therapy on Robitussin A-C can cause drowsiness due to the active ingredient, codeine. Codeine is a central nervous system depressant that can lead to drowsiness as a common side effect. This can impair the client's ability to perform tasks that require alertness. Choices B and C are incorrect because Robitussin A-C does not contain ingredients that are irritating to the bronchial tree, and using the medication for 14 days is not a major disadvantage. Choice D is incorrect as Robitussin A-C is not typically associated with being very expensive.
