What are the three types of inflammation ?

Acute- sudden onset
Sub acute-
Chronic-always there, slow
insidious

1

What is the first vascular response for acute (injury) inflammation ?

Brief vasoconstriction (for homeostasis )

2

What happens to blood flow during cellular response of inflammation

Blood flow SLOWS as fluid is lost

3

During cellular response, which blood cell is first to respond

WBC: neutrophils (within 6-12 hours)

4

Which cells increase in response to allergic disorders, inflammation of skin & parasitic infections?

Eosinophils

5

Describe acute inflammation Vascular response:

-vasoconstriction
-histamines released
-vessels dilate
-hyperemia (increased blood)
-increased capillary permeability

6

What is the adaptive mechanism of inflammation:

-destroy/dilute injurious agent
-prevent further spread of injury
-remove necrotic materials
-establish healing environment

7

Describe cellular response of inflammation:

-blood flow slows
-margination occurs
-diapedesis
-Chemotaxis

8

Which exudate is clear like plasma?

Serous

9

Which exudate is red with many RBCs?

Sanguineous

10

Which exudate is described as pinkish, watery with RBCs?

Serosanguineous

11

What is the final phase of healing?

Regeneration & Repair

12

Definition of Labile

Easily altered

13

What meds to consider in inflammatory process that can alter response?

Acetylcytic acid, NSAIDS, CoRticosteroids, acetaminophen

14

What are the local manifestations of inflammation?

-Redness
-Heat
-Pain
-Swelling
-Loss of function

15

What is the inflammatory response?

A sequential reaction to cell injury that neutralizes and dilutes the inflammatory agent, removes necrotic materials and establishes a suitable environment for healing and repair.

16

What are some variables that may affect the physiological tolerance to heat and cold?

-Body part, which parts are temperature sensitive?
-size of exposed body part
-length of exposure
-intactness of skin
- neurosensory impairment
-impaired mental status
-open wounds

17

What factors to primary prevention may interfere with wound healing?

-Malnutrition
-obesity
-decreased blood supply
-smoking
-tissue trauma
-chemotherapy
- infection

18

How does a deficiency in Vitamin C effect wound healing?

Delays formation of collagen fibers and capillary development

19

How can decreased protein levels effect wound healing?

It decreases the supply of amino acids for tissue repair.

20

An inadequate blood supply has what effect on would healing?

It decreases the supply of nutrients to injured area, decreases removal of exudative debris and inhibits the inflammatory response.

21

How does anemia effect wound healing?

Decrease in supply of oxygen at the tissue level.

22

What are sutures and fibrin sealant used for?

To facilitate in wound closure and to create an optimal setting for wound healing.

23

What is included in the assessment of a wound

-wound appearance
-tissue loss, wound margins, exudate
-inflammatory reaction
-granulation tissue

24

How long does it take to receive the results of a wound culture?

42-72 hours

25

When are early signs of an infection usually evident in primary intention wound healing?

Between the 3rd and 5th days

26

What are the stages of wound healing?

1) Inflammation
2) Repair
3) Reconstruction
4) Maturation

27

How long does the granulation phase last in primary intention wounds?

5 days to 3 weeks

28

What does RICE stand for?

REST
ICE
COMPRESSION
ELEVATION

29

What lab test would be done in a patient with acute inflammation?

Increases SED rate

30

Bandages are applied how & RAT for this?

Distal to proximal
-aids return of flow of venous blood

31

What type of WBC increases in the case of a viral infection?

Lymphocyte

32

Wound infection; what would leukocytes look like ? (#)

>11,000cm/blood

33

3 complications if primary intention wound healing:

Scar formation
Hypertrophic scar
Keloid formation

34

6 subscales of Braden scale

Sensory perception
Moisture
Activity
Mobility
Nutrition
Friction & shear

35

3 types of debridement

Sharp/surgery
Mechanical: wet-to-dry; irrigation, scrubbing
Enzymatic: drugs used to dissolve necrotic tissue (eg. Collagenese)

36

How to wrap dressings/ace wrap

Figure 8 toward body ( closest toward heart)

37

RYB color code;
RED:?
YELLOW:?
BLACK:?

Red-cover
Yellow-cleanse
Black-debridement

38

Stage:
Full thickness loss, subcutaneous fat visible, slough, tunneling visible

Stage III

39

Dressing: semi permeable membrane permits gas exchange. Used for dry non-infected wounds or for minimal drainage

Transparent films

40

Dressing: does not allow for O2 to I diffuse from wound, supports debridement, light to moderate drainage

Hydrocolloids

41

Dressing: used to hydrate dry wound & maintain moist healing environment, debridement purposes, partial full thickness, deep wounds with minimal drainage & necrotic wounds

Hydrogel

42

Dressing: non-adhesive pads/ribbons for wounds with moderate to heavy exudate

Alginates

43

How does complement system affect healing process?

Mediates and amplifies immune system

44

Why is there a temperature with inflammation ?

Release of endogenous pyrogens at inflammatory site
