Correct Answer is A
Explanation
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.
Correct Answer is B
Explanation
A. Nails no longer than 1⁄2 inch: While nails should be kept short and clean, this answer does not directly address the CDC’s recommendations for hand hygiene.
B. Using alcohol-based hand sanitizer with at least 60% alcohol: The CDC recommends using alcohol-based hand sanitizers with at least 60% alcohol for effective hand hygiene.
C. Washing visibly soiled hands with soap and water for 3 to 5 min: Hand washing should be performed for 20 seconds with soap and water, not 3 to 5 minutes. The duration mentioned is excessive and not in line with standard guidelines.
D. Artificial nails without cracks or chips: The CDC advises against wearing artificial nails when providing patient care, as they can harbor bacteria and pose an infection risk.
