-Protects the patient from infection and
to prevent the spread of pathogens
and/or harmful microorganisms

Microorganism-free area that can receive

sterile supplies

◦ Established using a sterile drape

◦ Contains no viable microorganisms

◦ Clean and dry materials only

◦ Unexpired and unopened materials

◦ Sterile corridor—area between patient

drape and instrument table

  • How two people in sterile attire pass each other
  • What to look for when first opening sterile package

1) 4 feet includes space for two people to meet and pass each other without touching either personnel wearing sterile attire standing at the sterile field or non-sterile surfaces

  • Important things to consider when x-raying a NICU baby

◦ Extra care required with aseptic techniques

◦ Often performed for transient tachypnea of the newborn (TTN) or respiratory distress syndrome (RDS)

The goal of aseptic technique

Clean, sanitize, and disinfect

  • What needs draped
  • How to drop sterile contents onto a sterile field

1) ◦ Drop the contents gently onto the
sterile field from about 6 inches above
the field and at a slight angle.
◦ This technique helps ensure that the
package wrapping does not touch the
sterile field at any time.
◦ DO NOT REACH ACROSS sterile
field A sterile field is established using a
sterile drape. 

2) patient and medical instruments (C-arm)

Pacemaker

  • What it does

Permanent pacemakers are electromechanical devices inserted under the patient’s skin to regulate the heart rate.

300
  • Patient instructions when removing NG tube
  • What a keofeed is

 

1)ask patient to take a deep breath as the tube is gently withdrawn.

2)Tube used for feeding patient

  • Definition of purgation
  • Enema tips

1) includes laxatives

2)  (Left) Plain barium enema tip. (Right) Barium enema tip with an inflatable cuff

Sources of infection

◦ Skin

◦ Hair

◦ Nasopharynx

◦ Fomites

◦ Air

◦ Human error

◦ Cross-contamination
