A nurse is reinforcing discharge teaching with a client following a cataract extraction. Which of the following should the nurse include in the teaching?

A. Flashes of light or sudden visual changes may indicate retinal detachment or other complications, and this is not normal after cataract surgery. Patients should be instructed to report any new visual disturbances immediately. B. After cataract extraction, intraocular pressure must be minimized to prevent complications such as increased intraocular pressure, wound dehiscence, or hemorrhage. Patients are taught to bend at the knees rather than the waist when picking up objects, avoid heavy lifting, and refrain from straining. This is a key postoperative safety and recovery measure. C. The eye shield is typically worn at night to protect the operative eye from accidental rubbing or trauma while sleeping. Removing it at bedtime would increase the risk of injury. D. Straining during bowel movements can increase intraocular pressure, so patients are generally encouraged to use stool softeners or mild laxatives if needed, rather than limiting them. This helps prevent postoperative complications.
