Which of the following actions should the nurse take?

The correct answer is B, to close the newborn's eyes before applying eyepatches. This is because closing the newborn's eyes before applying eyepatches helps to protect the eyes from irritation and ensures proper placement of the patches. Option A is incorrect as glucose water is not recommended for newborns after each feeding. Option C is incorrect as hydrating lotion may interfere with treatment or create a barrier for proper adhesion of medical devices. Option D is incorrect as turning the newborn every hour is not necessary and may disrupt their rest and sleep cycles.
