2. Sterile instruments and supplies are loaded onto the ___________ before surgery and transported to the surgical suite.
A. case cart C. personnel
B. elevator D. conveyor

ANS: A
Sterile instruments and supplies are loaded onto the cart before surgery and transported to the surgical suite.

PTS: 1 DIF: 2 REF: p. 204

3. ______________ items must be sterile. These items enter sterile tissue or the vascular system.
A. Semicritical C. Critical
B. Noncritical D. Low critical

ANS: C
Critical items are those that come in contact with sterile body tissues and internal organ systems, including the vascular system. Examples are surgical instruments, vascular cannulas, and hypodermic needles. All medical devices in this category must besterilized before patient use.

PTS: 1 DIF: 2 REF: p. 201

4. The first phase of reprocessing is _____________.
A. sorting C. sterilization
B. cleaning D. wrapping

ANS: A
The first phase of reprocessing is sorting. This is done to prevent damage to delicate items and prevent injury during reprocessing.

PTS: 1 DIF: 2 REF: p. 204

5. Because paper products are difficult or impossible to decontaminate, patient’s charts, x-rays, and lab documentation should be ________.
A. left outside of the surgical suite C. flash sterilized
B. kept free from contamination D. immediately placed in plastic bags

ANS: B
Because paper products are difficult or impossible to decontaminate, every effort should be made to keep patients’ charts, laboratory slips, radiograph reports and radiographs, and any paper documentation free of contamination.

PTS: 1 DIF: 2 REF: p. 225

6. The flash sterilizer is used to rapidly sterilize clean, decontaminated equipment for immediate use. This method is used only when no other method is available. Implants are ___________ sterilized except in an emergency and must be monitored with a biological control system.
A. just-in-time C. not flash
B. quick D. right-on-time

ANS: C
The flash sterilizer is used to rapidly sterilize clean, decontaminated equipment for immediate use. This method is used only when no other method is available. Implants are not flash sterilized except in an emergency and must be monitored with a biological control system.

PTS: 1 DIF: 2 REF: p. 216

7. The phrase flash sterilization has been replaced by _____________ sterilization, in which unwrapped surgical equipment is sterilized by a high-vacuum steam sterilization method just before use.
A. just-in-time C. right on time
B. quick D. immediate-use

ANS: D
The phrase flash sterilization has been replaced by immediate-use sterilization, in which unwrapped surgical equipment is sterilized by a high-vacuum steam sterilization method just before use. The phrase flash sterilization was retired because it does not provide an accurate description of the sterilization cycles used to process items for immediate use.

PTS: 1 DIF: 2 REF: p. 216

8. ___________________ is used to sterilize objects that cannot tolerate the heat, moisture, and pressure of steam sterilization.
A. Glutaraldehyde solution C. Gas plasma
B. Peracetic acid D. Ethylene oxide

ANS: D
Ethylene oxide is used to sterilize objects that cannot tolerate the heat, moisture, and pressure of steam sterilization.

PTS: 1 DIF: 2 REF: pp. 217-218

9. The temperature of the gas directly affects the penetration of items in the chamber. Operating temperatures range from ____________ for a “cold” cycle and ________ for a “warm” cycle.
A. 85°F to 100° F and 130° F to 145° F C. 85° F to 100° F and 100° F to 125° F
B. 75° F to 79° F and 130° F to 145° F D. 85° F to 95° F and 100° F to 115° F

ANS: A
The temperature of the gas directly affects the penetration of items in the chamber. Operating temperatures range from 85°F to 100°F for a “cold” cycle and 130°F to 145°F for a “warm” cycle.

PTS: 1 DIF: 2 REF: p. 218

10. The recommended practice to damp dust the surgical lights, furniture, and fixed equipment in the operating suite is ___________.
A. at the end of the day C. before each case of the day
B. before the beginning of each shift D. before the first case of the day

ANS: D
The recommended practice before the first case of the day is damp dusting of surgical lights, furniture, and fixed equipment in the operating suite. A clean, lint-free cloth and a hospital-grade chemical disinfectant are used.
