Chapter 22 : Surgical Asepsis Questions
Question 1 of 5
Which are restricted areas in the hospital to help maintain surgical asepsis?
Correct Answer: C,D,E
Rationale: Restricted areas like heart catheterization laboratories, surgical suites, and delivery rooms require strict surgical asepsis to minimize infection risk due to invasive procedures performed there.
Question 2 of 5

Correct Answer: B,D
Rationale: The parts of a sterile drape extending below the table surface are considered unsterile, and the outer 1-inch margin of the drape is also unsterile, allowing bare hand contact without contaminating the field. The other options are incorrect as they violate sterile technique principles.
Question 5 of 5
