(B) Fluid resistant
(C) Porous
(D) Flame retardant
(A) Prevent airborne particles from entering the surgical wound.
(B) Prevent strike-through contamination.
(C) Body heat is not retained, resulting in hyperthermia.
(D) Prevent them from igniting if exposed to the beam of laser or spark from an ESU.
Identify one advantage and one disadvantage of each type of fabric:
(A) Nonwoven fabrics
(B) Woven fabrics
(A) Advantage: Disposable; Disadvantage: May need extra fabric around the fenestration.

(A) Incise drape
(B) Aperture drape
(C) Isolation drape

You are setting up your case and notice the circulator adding an extension onto the table. She states the patient is more than 7 feet tall. What concerns do you have about the drape and how can you correct any problems, if necessary?
Contamination due to adding a nonfenestrated reinforced three-quarter sheet to sufficiently cover the feet, so we would need to pay attention to the drape during the surgery.
