inhalation injury
30
What should be done every hour?
- incentive spirometer - suctioning
31
What should be done for airway injury?
- supplemental O2 - coughing - deep breathing - elevate HOB
32
What should be done for F&E imbalances (hypovolemic shock)?
- daily weight - I&O's - labs - IV replacement
33
What should be assessed when monitoring for a wound infection?
- discoloration - edema - odor - drainage - fluctuating temp and HR
34
What should be done for a suspected wound infection?
- culture - antibiotics - labs
35
What is needed for dressing changes?
surgical asepsis
36
What can scar tissue cause?
limited movement, contractures
37
What should be done at least 3 times/day for mobility?
active or passive ROM
38
What position is encouraged?
neutral with limited flexion
39
What should be encouraged for mobility?
- splints - ambulation - compression dressings for up to 24 months
40

How many calories should someone consume after burns?
5000/day
44
What happens to caloric needs 4-12 days after the burn?

45
Why should protein be increased?
- prevents tissue breakdown - promotes healing
46
Why should calories be increased?
- increased metabolic demands - prevents hypoglycemia
47
Why would enteral therapy or TPN be needed?
- decreased GI motility - increased caloric needs
