Final answer:
The incorrect statement concerning prepping for ophthalmic surgery is that eyes are kept open during the prep. In practice, eyelids are kept closed to protect the eye while other areas are cleansed and eyebrows are not shaved unless necessary. The conjunctival sac is flushed with a safe agent, although benzalkonium chloride may be too irritating.
Step-by-step explanation:
The question concerns the proper procedures for prepping for ophthalmic surgery. Among the given options, the statement that is not true is C) "Eyes are kept open during the prep, so possible reactions to the prep can be noted." During the preparation for eye surgery, care must be taken to avoid any substances entering the eye that could cause harm or discomfort. The eyelids would typically be kept closed to protect the eye during the prep.
Moreover, A) Eyelids and periorbital areas are indeed cleansed with a non-staining antiseptic agent. This is to prevent postoperative infections and complications. B) Eyebrows should not be shaved or removed unless the surgeon deems this essential, as the statement correctly suggests that they may not grow back completely. D) The conjunctival sac is indeed flushed with a nontoxic agent to remove any debris or bacteria before surgery. However, benzalkonium chloride can be irritating to the eye, and hence other solutions such as balanced salt solutions are often preferred.
