A nurse is teaching a client who has a new prescription for benzonatate. Which of the following statements by the client indicates an understanding of the teaching?

The correct answer is A: "I should not drive while taking this medication." Benzonatate is a cough suppressant that can cause drowsiness and dizziness. Driving while taking this medication can impair the client's ability to operate a vehicle safely. This statement demonstrates an understanding of the potential side effects of benzonatate.
Choice B is incorrect because benzonatate is not an expectorant that helps with mucus clearance.
Choice C is incorrect as there is no need to decrease dietary fiber intake while taking benzonatate.
Choice D is incorrect because benzonatate should not be chewed as it may cause numbing of the mouth and throat.
