A nurse is reinforcing discharge teaching with a client who is postoperative following cataract removal. Which of the following instructions should the nurse include in the teaching?

Postoperative care following cataract removal focuses on protecting the surgical eye, preventing increased intraocular pressure, and promoting proper healing of the lens capsule. Clients are taught to avoid activities that increase eye strain or pressure, such as bending, heavy lifting, or rubbing the eye. Positioning and use of protective devices are key components of discharge education. Proper adherence to these instructions helps reduce the risk of complications such as hemorrhage, infection, or increased intraocular pressure. Rationale: A. Avoiding lying on the operative side helps prevent direct pressure on the surgical eye, which could increase intraocular pressure and disrupt healing. This positioning also reduces the risk of trauma and promotes comfort during recovery. It is a key protective measure in the early postoperative period. B. Bending at the waist increases intraocular pressure due to increased venous pressure in the head and eyes. This can place strain on the surgical site and increase the risk of complications such as bleeding or wound disruption. Clients are instructed to bend at the knees instead of the waist to avoid this pressure increase. C. The protective eye shield should be worn as prescribed, especially during sleep, to prevent accidental rubbing or injury to the operative eye. Removing it at bedtime would increase the risk of trauma during unconscious movements. Continuous protection during sleep is essential in the early healing phase. D. Experiencing a brow headache is not an expected or desired postoperative outcome. While mild discomfort may occur, persistent headache could indicate increased intraocular pressure or other complications. Any significant or worsening pain should be reported to the healthcare provider promptly.
