A nurse is teaching a client who has glaucoma and a new prescription for timolol eyedrops. Which of the following statements by the client indicates an understanding of the teaching?

A. "I should expect my tears to turn a red color after using the eye drops.": Timolol does not cause red discoloration of tears. Redness of the eye may indicate irritation, allergy, or another adverse effect, so the client should report persistent redness rather than expect it as normal. B. "I will put pressure on the corner of my eye after using the eye drops.": Applying gentle pressure to the nasolacrimal duct (inner corner of the eye) after instilling timolol reduces systemic absorption and potential systemic side effects, such as bradycardia or hypotension. This technique demonstrates proper administration and understanding of safety precautions. C. "The drops should be placed in the center of my eye.": Eye drops should be instilled into the lower conjunctival sac, not directly onto the center of the cornea, to reduce irritation and maximize absorption. Placing drops on the cornea can cause discomfort and reduce effectiveness. D. "These drops will improve my cloudy vision.": Timolol lowers intraocular pressure but does not restore vision or improve cloudiness caused by glaucoma. The goal of therapy is to prevent progression of vision loss, not to reverse existing damage.
