A client with a cold is taking the antitussive medication benzonatate. Which assessment information indicates to the nurse that the medication is effective?

Choice A reason: Denying having coughing spells indicates that the antitussive medication benzonatate is effective. Benzonatate works by numbing the throat and lungs, reducing the cough reflex. This means that if the client is no longer experiencing coughing spells, the medication is performing its intended function.Choice B reason: Being able to sleep through the night can be an indirect indicator of the medication’s effectiveness, but it is not as specific as denying coughing spells. While improved sleep might result from reduced coughing, it could also be influenced by other factors such as overall improvement in the client’s condition or the use of other medications.Choice C reason: Expectorating bronchial secretions is not a direct indicator of the effectiveness of benzonatate. Benzonatate is an antitussive, meaning it suppresses the cough reflex rather than promoting the expulsion of mucus. Therefore, expectorating bronchial secretions would not be a primary measure of this medication’s effectiveness.Choice D reason: Reporting reduced nasal discharge is also not a direct indicator of the effectiveness of benzonatate. This medication specifically targets the cough reflex and does not have a significant impact on nasal discharge. Reduced nasal discharge could be due to other factors or treatments.
