Emory - Systemic Factors Affecting Wound Healing Test
Questions with Answers
What are the main 9 factors to assess / correct for in wound healing?

1) Perfusion / oxygenation
2) Smoking / tobacco use
3) Nutritional status
4) Diabetes w/t hyperglycemia
5) Steroids
6) Comorbidities
7) Denervation
8) Obesity
9) Aging

True or False


More O2 is used in the inflammatory phase than the proliferative phase.

True

What is the optimal O2 range for wound healing?

30 - 40mmHg

How does a wound heal at each O2 range listed?


1) O2 > 40mmHg
2) O2 30 - 40mmHg
3) O2 < 30mmHg
4) O2 < 20mmHg

1) All wounds will heal
2) Optimal range for consistent wound healing

, 3) Healing is variable
4) No wound healing can occur

How do these factors impact perfusion status?
1) Unrelieved pressure
2) Cardiovascular disease
3) Edema
4) Anemia
5) Smoking

1) Tissue and blood vessel compression = ischemia
2) Significant impairment -> poor perfusion = sluggish healing
3) Impaired O2 exchange = barrier between blood vessels and wound bed
4) Less RBCs = less O2 delivery
5) Vasoconstriction = impedes O2 delivery via RBCs

At what level does impaired perfusion occur in relation to hemoglobin?

At a Hgb level of 6.0 - 8.0

Smoking impairs tissue oxygenation by causing __________ within blood vessels.

Vasoconstriction

How can a WOCN encourage patients to partake in smoking cessation?
1) Education and counseling
2) Nicotine patches
3) Medications
4) Lack of compassion and understanding
5) Answers 1), 2), and 3)

5) Answers 1), 2) and 3)

What is the goal blood glucose and A1C for optimal wound healing?
