A medical assistant is escorting a patient who has presbyopia. Which of the following actions should the assistant take?
Offer the patient their elbow for guidance.
Take the patient's hand.
Lead the patient by their arm.
Guide the patient by holding their waist.
The Correct Answer is A
A. Offer the patient their elbow for guidance: Offering the elbow is a common and safe method of guiding patients with visual impairments, including presbyopia, because it allows the patient to follow the assistant's movements more easily.
B. Take the patient's hand. Taking the patient's hand might make the patient feel less secure and can lead to an imbalance. It is less effective than offering the elbow.
C. Lead the patient by their arm: Leading the patient by their arm can be uncomfortable and does not provide the same level of control as offering the elbow.
D. Guide the patient by holding their waist: Holding the waist is inappropriate as it invades personal space and might make the patient uncomfortable.
