Which pre-operative instruction is critical for a client scheduled for surgery to repair retinal detachment?

Restricting head movement is critical for a client scheduled for surgery to repair retinal detachment because excessive movement can increase the risk of further retinal tears or detachment. The specific positioning and movement restrictions help ensure that the retina remains stable and undisturbed prior to surgery. This precaution is essential for the healing process and overall success of the surgical intervention.

In the context of retinal detachment, the focus is on minimizing any actions that could aggravate the condition or interfere with the surgical procedure. Therefore, restricting head movement effectively reduces strain on the eyes and limits the chances of worsening the detachment. This aspect of pre-operative care directly influences the safety and potential success of the surgery.
