Final answer:
The nurse emphasizes the importance of therapy to reduce intraocular pressure in order to prevent blindness in the client with glaucoma.
Step-by-step explanation:
The nurse emphasizes the importance of therapy to reduce intraocular pressure in order to prevent blindness in the client with glaucoma. High pressure within the eye can damage the optic nerve over time and lead to irreversible vision loss. By reducing the intraocular pressure, the eye drops help to alleviate the strain on the optic nerve and prevent further damage, ultimately preserving the person's vision. Therefore, the correct answer is D. Blindness. A nurse is educating a client on the importance of proper administration of eye drops for the treatment of glaucoma. Glaucoma is a condition wherein the fluid pressure inside the eye, referred to as intraocular pressure, increases due to blocked circulation of fluid. If untreated, this buildup of pressure can lead to optic nerve damage and, subsequently, blindness. It's important to manage glaucoma not only to alleviate symptoms such as headaches but to prevent permanent vision loss. Therefore, the nurse stresses the significance of adhering to the prescribed treatment to maintain intraocular pressure at normal levels and avoid serious complications including blindness.
