During patient skin preparation, which area should be prepped last?

• A. Face
• B. Arms
• C. Legs
• D. Stoma

Answer: (D)

The key idea is preserving a sterile field by sequencing skin prep to minimize contamination of the operative area. The stoma area is the most likely to harbor intestinal bacteria and secretions, so it should be cleaned last to prevent any of that material from recontaminating skin that’s near the incision after the rest of the skin has already been prepped. The face, arms, and legs are farther from the surgical site or carry less direct risk of contaminating the wound, so they’re prepared earlier in the sequence. Finishing with the stoma helps protect the sterility of the operative area and reduce the chance of postoperative infection.
