A client with open-angle glaucoma asks the nurse how long the prescribed eye drops will need to be used. Which response made by the nurse is accurate?

Choice A reason: Using the eye drops until the excess pressure is reduced is not an accurate response, as it implies that the eye drops are only a temporary treatment. Open-angle glaucoma is a chronic condition that causes increased pressure in the eye due to impaired drainage of the aqueous humor. The eye drops are used to lower the eye pressure and prevent further damage to the optic nerve. The client will need to use the eye drops for the rest of their life, unless the healthcare provider advises otherwise.Choice B reason: Using the eye drops for long-term control of pain and swelling is not an accurate response, as it does not address the main goal of the treatment. Open-angle glaucoma does not usually cause pain or swelling, as the pressure builds up gradually and painlessly. The eye drops are used to lower the eye pressure and prevent vision loss, not to relieve inflammation or discomfort.Choice C reason: Using the eye drops until a smaller angle can be restored is not an accurate response, as it confuses open-angle glaucoma with closed-angle glaucoma. Open-angle glaucoma is characterized by a wide and open angle between the iris and the cornea, which allows the aqueous humor to flow freely. Closed-angle glaucoma is characterized by a narrow or closed angle that blocks the drainage of the aqueous humor. The eye drops are used to lower the eye pressure and prevent further damage to the optic nerve, not to change the angle of the eye.Choice D reason: Using the eye drops for long-term control of normal eye pressure is the most accurate response, as it reflects the purpose and duration of the treatment. Open-angle glaucoma is a chronic condition that requires lifelong management. The eye drops are used to lower the eye pressure and prevent vision loss, which can occur if the pressure is too high for too long. The client should use the eye drops as prescribed and follow up with the healthcare provider regularly.
