The nurse can best ensure that communication is understood by:

A. Speaking in simple sentences, as if to a child. This is inappropriate and could be perceived as patronizing, which may hinder communication. Older adults should be treated with respect, not as children.

B. Speaking slowly in order to allow the patient to process the message. Older adults may need more time to process information, so speaking slowly can aid understanding without appearing patronizing.

C. Addressing him by his first name to encourage a therapeutic relationship. Addressing older adults by their first names may be seen as disrespectful or overly familiar, unless the patient specifically requests it.

D. Standing in the doorway rather than entering the room to give the older adult patient more privacy. Standing in the doorway may create a physical barrier and distance, which can hinder effective communication and rapport.

A. Speaking slowly and clearly in the patient's native language. While speaking clearly in the patient’s native language is helpful, it does not verify understanding. Feedback from the patient is necessary to confirm comprehension.

B. Asking the family members whether the patient understands. Relying on family members may not be accurate, as they may not fully understand the patient's level of comprehension.

C. Obtaining feedback from the patient that indicates accurate comprehension. Having the patient repeat the information back or summarize it in their own words ensures they have understood the communication.

D. Checking for signs of hearing loss or aphasia before communicating. Assessing for hearing loss or aphasia can be part of the process but does not confirm that communication was understood.
