Which of the following actions should the nurse take?

The correct answer is C: Close the newborn's eyes before applying eyepatches. This is important to prevent any irritation or discomfort to the newborn when applying eyepatches. Closing the eyes ensures that the patches adhere properly and do not cause any harm. Providing glucose water (A) is unnecessary and not recommended for newborns. Turning the newborn every 4 hours (B) is a good practice for preventing pressure ulcers in older patients, not typically needed for newborns. Applying hydrating lotion (D) prior to treatment may interfere with the effectiveness of the treatment and is not a recommended practice for newborn care.
