Q

Necrotizing soft tissue infections (NSTI)

A

infection where part of the wound had dead tissue. This is a problem because this decaying tissue is perfect for bacterial growth.

They are opportunistic infecting you when introduced with a break in the protection of the skin.
28
What would you look at during an assessment of a skin infection
vital signs (tachycardia, change in LOC) Labs WBC establish baseline for skin culture for ABx nutritional status- how do they eat and how much.
29
What kind of nutrition do you need to look for during an infection?
Protein as well as fluids protein helps with tissue growth fluid loss can happen with an open sore and needs to be increased.
30
What are the basic labs drawn with an infection
CBC, serum electrolytes, c-reactive proteins.
31
What does the lab value for C-reactive protein tell you?
this is a protein that you watch that can be a monitor for inflammation.
32
What are the three ways to make a diagnosis of an infection?
Laboratory data, biopsies such as needle or punch. nasal swabs/ wound swab.
33
What can an infection do to your blood pressure
the infection can lead to less fluid in the intravascular space causing hypotension.
34
MRSA usually causes skin infections in the community what can it cause in a medical facility?
Sepsis, pneumonia, surgical site infections.
35
What is the isolation for MRSA
Contact precautions, Gown, gloves, hand washing.
36
What is the highest at risk population for MRSA
kids, prisoners, athletes, patients. Sharing of items such as hats or cups. Direct contact so anything that is easily touched and shared.
37
How does MRSA present itself?
Most of the time CA- MRSA is an uncomplicated skin infection. showing as an infection at the site of impaired skin integrity. (Cellulitis, folliculitis, impetigo, abscess).
38
Signs and diagnosis of MRSA
Like cellulitis redness, warmth, and swelling to area. Need culture to tell MRSA
39
How did MRSA become a thing?
Overuse or misuse of antibiotics not taking all led to a resistance in bacteria.
40
Treatment for MRSA
elevation to help with the swelling. Antibiotics to fight the infection. keep area clean/ dry
41
What should you always do with MRSA
Contact precautions stop the spread
42
What is the "big gun" antibiotic used for MRSA
Vancomycin used only when SIRS is met to avoid VRSA

What are some antibiotics that are used for MRSA
Bactrim Clindamycin Minocycline Doxycycline vancomycin

58
What are most cellulitis cases caused by?
Bacteria so they antibiotics.
59

To track infection and effectiveness of treatment.
60
What are the common complications related to cellulitis?
