During an interview, an older adult client answers some questions inappropriately. The practical nurse (PN) observes there is a hearing aid in one ear. Which intervention is most helpful in assisting the client to hear the PN's question?

A. Raise the pitch of your voice and speak slower: Higher pitch may make it harder for older adults to hear; slowing speech can help but low pitch is better. B. Sit with light of window behind you: Causes glare and makes lip reading harder. C. Restate questions articulating consonants carefully: Clear articulation improves comprehension without straining the voice. D. Stand above client and speak loudly: Loudness can distort sound and is uncomfortable.
