When measuring a wound using the clock-method, which statements are correct about length, width, and depth documentation?

• A. Measure length and width using the clock reference (length 3–9 o'clock, width 12–6 o'clock); document depth with a sterile probe and note tunneling/undermining.
• B. Measure length from 12 to 6 and width from 3 to 9; depth is estimated visually.
• C. Use a ruler to measure length and width; depth is not recorded.
• D. Length and width are measured in centimeters only; tunneling is not recorded.

Answer: (A)

Measuring a wound with the clock-method uses a clock face to describe its dimensions and orientation, giving a standardized way to capture irregular shapes. Length is described from 3 to 9 o'clock and width from 12 to 6 o'clock. Depth is assessed with a sterile probe to determine how deep the wound goes and to identify any tunneling or undermining, which must be noted in the documentation. Using only a ruler or reporting measurements in centimeters without depth, estimating depth visually, or omitting tunneling/undermining misses essential details needed to monitor healing and plan care, so those approaches aren’t correct. The clock-method with sterile probing for depth and explicit recording of tunneling/undermining provides the most complete and accurate wound description.
