Which of the following is true regarding the positioning and prepping of a patient undergoing ophthalmic surgery?

In ophthalmic surgery, the patient is typically positioned in the supine position, which allows the surgeon optimal access to the eye while ensuring the safety and comfort of the patient. This positioning is critical because it provides stability and reduces movement during the delicate procedure.

In terms of prepping, the use of betadine solution is standard practice due to its efficacy as an antiseptic agent that reduces the risk of infection. The prepping process typically involves painting the betadine solution onto the area around the eye, which helps to create a sterile field necessary for surgery. This combination of supine positioning and the use of betadine is crucial for achieving the best outcomes in ophthalmic procedures.

The other options present incorrect practices that would not align with standard protocols for ophthalmic surgery, such as inappropriate positioning or using non-standard antiseptics. Thus, the correct approach reinforced by the answer highlights important principles of both patient preparation and surgical positioning specific to ophthalmic procedures.
