Percentage of Staff Missing Question

1. A tray of cystoscopy instruments was displayed.
Q: How long should this tray of instruments be sterilized?

A. 3 minutes
B. 10 minutes
C. 15 minutes
D. Should not be Flashed

Porous items and lumened instruments must be flashed for 10 minutes in a gravity sterilizer

16%

2. The same tray of instruments as in question #1 was again displayed. The chemical integrator and autoclave printout supported a ten minute autoclave run.
Q: This tray was sterilized for 10 minutes. Is it sterile?

A. Yes
B. No

All valves in the tray were closed. Steam cannot penetrate through closed valves. This tray should be considered unsterile secondary to improper instrument preparation.

59%

3. A tray of minor non-porous and non-lumened instruments was placed in an autoclave. A previously used chemical integrator was left in the tray. The autoclave jacket pressure was set at 20 lbs of pressure. The printout indicated a flash cycle of 3 minutes.
Q. Is this tray sterile?

A. Yes
B. No

Although the integrator indicated that the parameters of sterilization had been met, the autoclave jacket pressure of 20 lbs would not have allowed the autoclave to sterilize the instruments in three minutes. Closer review of the printout would have shown a three minutes flash run but at a temperature of 257 degrees F. Correct temperature setting should be 271-273 degrees F. Staff are expected to know the correct operating parameters of the autoclaves. This tray is presumed to be unsterile.

4. A 3-M mini driver drill assembly was displayed. A list of the manufacturers recommendations is posted next to each autoclave.
Q. How long do you flash sterilize this tray

A. 10 minutes
B. 15 minutes
C. 55 minutes
D. Should not be flashed

AORN recommends to check with the manufacturer of the equipment being used to determine the correct cycle for the particular equipment. In their haste, many staff forgot to look at the posted recommended parameters.

5. A Dyonics arthroscopic shaver was displayed.
Q: This tray was flash sterilized for 10 minutes. Is it sterile?

A. Yes
B. No

Although 10 minutes was the appropriate time, the suction valve for the shaver was closed. This instrument should be considered un-sterile secondary to improper instrument preparation.

57%

This outcome is the same as question #2 which tested the same principle.

6. A typical tray of minor non-porous and non-lumened instruments was placed in an autoclave. The chemical integrator lying in the bottom of the autoclave indicated that the conditions of sterilization had been achieved.
Q: is this tray sterile?

A. Yes
B. No

A three step process must occur when assessing the success of a sterilization cycle.
1) Read the printout to see if the run was successful and what parameters were used.
2) See if the chemical integrator or indicator responded to a sterilization cycle.
3) Inspect the instruments to assure that they were properly prepared and the appropriate cycle was chosen.

The printout at this station was blank indicating that the autoclave had not recently run. The integrator was not placed in the tray and was most likely an old integrator from a previous run.

7. The following question was posted on an autoclave.
Q: What type of Autoclave is this?

A. Gravity only
B. Hi Vac only
C. Gravity/Hi Vac Combined

Staff are expected to be familiar with the capabilities of the equipment they are using. Fundamental to that is an understanding with regard to the type of equipment they are using.

40%

8. A Craniotome was on display.
Q: How long should you flash sterilize this tray?

A. 3 minutes
B. 10 minutes
C. 55 minutes
D. Should not be flashed

Specific power instrumentation is posted at each autoclave. Manufacturers recommendations must be followed.

50%

As in question # 4 the haste of the moment caused the staff to forget that the proper parameters were posted at the autoclaves.

9. A microaire 2000 was on display.
Q: How long should you flash sterilize this tray?

A. 3 minutes
B. 10 minutes
C. 30 minutes
D. Should not be flashed

Specific power instrumentation is posted at each autoclave. Manufacturers recommendations must be followed.

50%

As in question # 4 the haste of the moment caused the staff to forget that the proper parameters were posted at the autoclaves.

10. A Padgett dermatome was on display.
Q: How long should you flash sterilize this tray?

A. 3 minutes
B. 10 minutes
C. 55 minutes
D. Should not be flashed

This Padgett requires gas sterilization. Staff may not only injure patients with improper practice but also can damage or shorten the effective life of instrumentation if improper sterilization parameters are used.
