NR 224 Sterile Field Certification Assignment

Contact (direct and indirect) no mask, only gown and gloves, normal room (MRSA, VRE,
Shigella and C. diff)
• Droplet: particles greater than 5 microns (flu, pneumonia in infants, strep in infants,
rubella, mumps, pertussis) need a regular mask, gown and gloves, in a regular room
• Airborne: particles less than 5 microns; need N95 respirator mask, gown and gloves;
needs a negative pressure flow room (Ebola, TB, varicella, measles)
• Protective Environment: you do not want the patient to get sick because they are
immunocompromised (positive pressure) need a gown, mask and gloves
Wound Assessment
Drainage:
• Serous= clear, watery plasma
• Purlent= yellow/brown, thick
• Serosanguineous= mixture of plasma and a little bit of blood
• Sanguineous= red; active bleeding

Phases:
• Inflammatory= redness and swelling
• Proliferative= wound is filled with granulation tissue (scar tissue, NOT COLLAGEN)
• Remodeling= maturation of the new skin
Vocab:
• Dehiscene= total or partial separation of wound layers (BAD)
• Evisceration= protrusion of visceral organs through a wound opening
• Tissue Ischemia= reduced sensation
Factors Influencing Pressure Ulcers or Wound Healing:
• Nutrition
• Tissue perfusion
• Infection
• Age
• Psychosocial impact of wounds

KINDLY ORDER NOW FOR A CUSTOM-WRITTEN, PLAGIARISM-FREE PAPER

Assessing the Wound:
• Palpate it
• Edges should be clean and well approximated
• Crusts can form on edges due to exudate
• Inflammation after 2-3 days is abnormal
• At 7-10 days the edges should close
• Infection= inflamed and swollen and has a bad odor
• Assessing for odor, color, and the amount/consistency of the drainage

To determine amount of drainage= weigh the bandage that’s dirty compared to a clean
bandage (1 gram of weight = 1 mL of drainage
Putting on PPE Order:
• Gown
• Mask
• Eyewear
• Gloves
Taking off PPE Order:
• Gloves
• Eyewear
• Gown
• Mask
Medical vs. Surgical Asepsis:
• Surgical= sterile technique (removes spores)
• Medical = clean technique
Collecting a Specimen:
• Blood
• Stool
• Urine
• Wound drainage (can be cultured)
Chain of Infection:
• Infections agent/pathogen
• Reservoir for it to grow
• Port of exit
• Mode of transmission
• Port of entry
• Susceptible host
HAI= Hospital Associated Infection (MRSA, VRE, C. diff, etc)
• Lactogenic- infection from a procedure
• Exogenous- infection from outside of the body (ex. salmonella)
• Endogenous- overgrowth of normal flora
Localized infection= in one area (ex. wound)
Systemic infection= impacts the entire body
Inflammation= protective, vascular reaction that delivers fluid, blood products, and nutrients to an area of injury
