Final answer:
In a health assessment with an older adult, the nurse should slow down and give the patient more time to respond to questions, ensuring patience and respect for the individual's autonomy.
Step-by-step explanation:
When conducting a health assessment with an older adult who takes longer to answer questions than younger clients, the appropriate action for a nurse would be to slow the pace and allow extra time for the patient to answer. It is essential not to jump to conclusions about the client's cognitive abilities, such as assuming the presence of dementia without proper assessment and diagnosis. Furthermore, the nurse should remain patient and considerate, avoiding the replacement of the client's responses with answers from family members unless absolutely necessary and with the client's consent.
