A nurse is assessing a client who had a stroke 2 days ago. Which of the following findings should the nurse identify as a need for a referral to speech-language pathology?

The correct answer is D: Impaired voluntary cough. This finding indicates a potential swallowing dysfunction, which is a common complication post-stroke. Referral to speech-language pathology is crucial to assess and manage dysphagia to prevent aspiration pneumonia. Diminished hand-to-mouth coordination (A) may indicate motor deficits but does not directly impact swallowing. Altered level of consciousness (B) is concerning but does not specifically warrant a speech-language pathology referral. Unilateral ptosis (C) is a drooping eyelid and is not related to speech or swallowing.
