Which of the following is considered a semi-critical instrument?

Question

Quizplus · Accepted Answer

A semi-critical instrument is an instrument that comes in contact with mucous membranes, but does not penetrate soft tissue or bone. An X-ray receptor-holding device like a sensor or film holder is an example of a semi-critical instrument because it comes in contact with mucous membranes, but does not penetrate soft tissue or bone. Lead aprons, exposure buttons, and position-indicating devices do not come in contact with patients and are therefore not considered semi-critical instruments.
