Background And Purpose:
Nurses must competently demonstrate psychomotor skills. Few reliable and valid instruments are available for psychomotor evaluation for disaster skills, including the skill of decontamination.
Objectives:
The purpose of this study was to develop and refine an instrument to measure the skill of decontamination.
Design:
A seven step instrument development design was implemented that included content validity and reliability as well as inter-rater reliability analysis.
Setting And Participants:
A convenience sample of approximately 140 participants was drawn from two colleges of nursing at two large academic universities. The sample included senior nursing students in either their community or final practicum nursing course.
Methods:
Based on a sample of 140 students who participated in a decontamination training experience using virtual reality simulation, a seven step established process for assessment of reliability and validity was implemented to develop a checklist for the skill of decontamination.
Results:
The final instrument statistics: Content Validity Index for the overall instrument score was 0.94, Internal consistency coefficient=0.607(KR-20) and Inter-rater reliability=0.9114.
Conclusions:
This instrument provides a reliable and valid assessment of nurses' competency in performing the skill of decontamination offering a template for educators to develop similar tools.

Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.

The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury. The nails must be short and clean, without nail...
