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?

Choice A rationale Benzonatate is a non-narcotic cough suppressant that works by numbing the throat and lungs, making the cough reflex less active. It can cause drowsiness and dizziness, so patients are advised not to drive or operate heavy machinery while taking this medication. Choice B rationale Benzonatate does not help in coughing up mucus. It suppresses the cough reflex, which can be beneficial for dry, irritating coughs but is not suitable for productive coughs where mucus needs to be expelled. Choice C rationale There is no need to decrease dietary fiber intake while taking benzonatate. Dietary fiber does not interact with the medication or its effectiveness. Choice D rationale Benzonatate capsules should not be chewed or crushed, as this can cause numbness of the mouth and throat, leading to potential choking hazards.
