For which of the following procedures is verbal consent sufficient?

A. Pull the lower eyelid down. Pulling the lower eyelid down creates a pocket for the drops, making it easier to administer them without contacting the eye’s surface directly.
B. Have the patient open their eye using both hands: Using both hands to open the eye may be uncomfortable and unnecessary; the assistant should guide the patient gently.
C. Use a retractor on the eye before administering the drops: Retractors are not typically used for eye drop administration; this can cause discomfort and is not standard practice.
D. Hold the dropper 1 inch away from the surface of the eye: The dropper should be held close enough to the eye to avoid contaminating the eye surface or the dropper, but not so close as to touch the eye.

A. 1/4 inch: A 1/4 inch border is too small to be considered a standard contaminated area. The correct border size is larger.
B. 1/2 inch: A 1/2 inch border is also not standard; the correct contaminated border is larger.
C. 1 inch: The standard for sterile fields is to consider a 1-inch border around the edge of the sterile field as contaminated. This helps to prevent inadvertent contamination of sterile items.
D. 1 1/2 inches: A 1 1/2 inch border is unnecessarily large and exceeds the standard 1-inch margin considered contaminated.
