Wound Collection Retain Flashcards
(73 cards)
What are they two types of testing for wounds?
Culture and sensitivity
What does a sensitivity wound culture determine?
Proper antibiotic therapy
What does a wound culture determine?
organisms that grow in the presence oxygen (aerobic) or without oxygen (anaerobic)
administer analgesic 30 min before procedure
Where should the nurse collect the specimen from ?
The center of the wound - NOT from the edges because it could contain skin flora and the procedure has to be repeated
Two things to never do when collecting a wound specimen are
- never collect from pus or pooled exudates
- never touch the swab to the outside of the test tube
Do you use the same swab in the drainage?
no
you rotate sterile swabs in the drainage
What makes a sputum specimen contaminated?
saliva
How much sputum is needed for a specimen collection?
1-2 tsp of sputum
What time of the day should sputum specimens be collected? and what is the rationale?
Collect sputum first thing in the morning before eating or drinking - the results are more accurate
What are ways to reduce contamination of sputum specimen?
clearing the nose and throat
rinsing the mouth
Which method is used to help a pt who is only producing saliva in specimen cup?
chest physiotherapy (postural drainage to help mobilize mucus and facilitate expectoration)
To collect a specimen of sputum, what is the method so that it is performed correctly?
Early in the morning 3 days in a row
Where are throat specimens collected?
Oropharynx or tonsillar region using a sterile swab.
A throat specimen can be contaminated if the sterile swab touches which parts of the mouth?
gums
tongue
teeth
Which is more accurate point of care (in the medical facility) or the lab?
Lab testing is more accurate
What are the risks of collecting specimens that can lead to a false positive or false negative?
storage conditions
poor method of specimen collecting
not rotating sterile swabs
Which solutions are used to irrigate or clean wounds
Isotonic saline
wound cleansers
If an antimicrobial solution is used to irrigate or clean a wound the nurse needs to ensure the solution is
diluted
Why is it contraindicated to microwave liquids or used cold liquids on a wound
lowering the wound temperature slows down the healing process
microwaving the solution could make it too hot
Solutions that are going on a wound should be this temperature
warm the solution to body temperature
Why should the nurse avoid drying the wound after cleaning it
helps retain wound moisture
If a wound is clean, has little exudate, and reveals healthy granulation (lumpy pink tissue containing new connective tissue and capillaries form around the edges of the wound), the nurse should avoid doing this and why
the nurse should avoid repeated cleaning because unnecessary cleaning can delay wound healing by traumatizing the newly produced tissues
if the wound appears clean, consider not cleaning it at all
What factors affect wound healing?
mental illness (they are not thinking of staying clean)
medications (antibiotics - tetracyclines, corticosteroids)
suppressed immune system
anti-neoplasm (drugs that are used to treat cancer)
cyclo-therapeutics
poor nutrition
What are tetracyclines and corticosteroids and how do they affect wound healing?
o corticosteroids - anti-inflammatory
-reduces swelling in mucous membranes
- increases risk of infection
o tetracycline - protein synthesis inhibitor antibacterial
- slows protein synthesis preventing bacterial from forming bacteria uses protein to stay alive and multiply
