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

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)

Using the clock method standardizes wound documentation by describing dimensions with a clock-face orientation. The long axis is recorded from 3 o'clock to 9 o'clock, the width from 12 o'clock to 6 o'clock, and depth is measured with a sterile probe while noting any tunneling or undermining. This approach captures not just size but also the contours and extensions of the wound, which are crucial for assessing healing and planning treatment.

This is why the correct statement is best: it follows the clock reference for length and width and uses a sterile probe to measure depth while documenting tunneling or undermining. The other methods misalign with the clock approach—some swap the axes, some estimate depth visually, some use a ruler instead of the clock reference, and some skip recording depth or tunneling—which leads to incomplete or inconsistent wound documentation.
