A client diagnosed with primary open-angle glaucoma received a prescription for miotic eye drops. Which instruction should the nurse plan to include in this client's teaching?

A. "Wash your hands after each administration of eye drops" is important but not specific to the safe administration of miotic eye drops. Washing hands before administration is more relevant to preventing infection. B. "Squeeze your eye closed after administering the drops" can force the medication out of the eye, reducing its effectiveness. Instead, the client should be instructed to close the eye gently and apply pressure to the inner canthus to prevent systemic absorption. C. "Do not allow the dropper bottle to touch the eye" is correct because it prevents contamination of the dropper, which could lead to eye infections. D. "Administer the medication directly on the cornea" is incorrect because eye drops should be placed in the conjunctival sac, not directly on the cornea, to minimize irritation and maximize absorption.
