A) Centimeters
B) Inches
C) Micrometers
D) Millimeters
D
Feedback:
The nurse should measure the degree of edema in terms of millimeters when performing a skin test. The degree of edema indicates the severity of the allergic reaction. Millimeters are metric equivalents of meters, used to measure length. Degree of edema is not measured in centimeters or inches; they are used for much bigger measurements. Although micrometers are metric equivalents of length, they are used for smaller measurements and not to measure the degree of edema in skin testing.
