The nurse is teaching a school-age child about factors that can delay wound healing. What factors should the nurse include in the teaching session? (Select all that apply.)
a. Deficient vitamin C
b. Deficient vitamin D
c. Increased circulation
d. Dry wound environment
e. Increase in white blood cells
ANS: A, B, D
Factors that delay wound healing are a dry wound environment (allows epithelial cells to dry), deficient vitamin C (inhibits formation of collagen fibers), and deficient vitamin D (regulates growth and differentiation of cell types). Decreased, not increased, circulation delays healing. An increase in the white blood cell count may occur but does not delay healing.

A. "Elevated eye pressure can cause high blood pressure." B. "If eye pressure is too high, your eyes will bulge forward enough that your lids can't cover them and they will dry out." C. "Elevated eye pressure can press on blood vessels in the eye, keeping eye nerves from getting enough oxygen, which will lead to blindness." D. "Increased eye pressure causes the tear ducts to become blocked so that you have insufficient tears. It is the tears that protect the cornea from abrasions."
