Final answer:
A medical assistant should provide written instructions in large font, use body gestures, and notify the patient when entering the room when providing discharge instructions for a patient with visual impairment.
Step-by-step explanation:
When providing discharge instructions for a patient with visual impairment, the medical assistant should take several actions to ensure effective communication. One of these actions is to provide written instructions in large font so that the patient can easily read them. This accommodates their visual impairment and promotes understanding of the instructions.
Another action the medical assistant should take is to use body gestures when communicating. Body gestures can help convey information and enhance understanding for visual impaired individuals by providing additional visual cues.
Lastly, the medical assistant should notify the patient when entering the room. This alerts the patient to the assistant's presence and prepares them for any instructions or information that will be provided.
