Clean it, bandage it, and do not remove the skin.

1) Relevant knowledge points and concepts
- A blister is a pocket of fluid (serum) that forms between layers of skin after friction, burns, or other trauma. The intact blister roof (the overlying epidermis) acts as a natural sterile barrier that protects the raw tissue beneath and reduces pain.
- Infection risk increases when the skin barrier is broken; basic wound care (cleaning, protecting, and monitoring) minimizes this risk.
- Improper actions such as intentional drainage without sterile technique, leaving a denuded wound exposed, or applying extreme cold directly to damaged skin can increase pain, tissue damage, or infection.

2) Step-by-step reasoning process
- If a blister pops spontaneously or is accidentally ruptured, first assume the area is now an open wound that needs gentle cleaning to remove dirt and bacteria.
- Cleaning reduces microbial load, bandaging protects against contamination and friction, and preserving the remaining epidermal skin (if present) maintains a biologic cover that helps healing and reduces infection.

3) Practical intermediate steps
- Wash hands thoroughly.
- Gently rinse the blister with clean water and mild soap or use a saline/antiseptic wipe (povidone-iodine or chlorhexidine if available).
- Pat dry with clean gauze, apply a thin layer of antibiotic ointment if desired, then cover with a sterile, non-stick dressing (e.g., bandage or hydrocolloid pad).
- Change dressing daily or sooner if it becomes wet/dirty; watch for increased redness, warmth, swelling, pus, or fever.

4) Why the correct answer is correct
- "Clean it, bandage it, and do not remove the skin" preserves the protective epidermal layer, lowers infection risk, and promotes faster, less painful healing. This follows standard first-aid and wound-care principles.

5) Why other options are incorrect
- "Drain it immediately": Intentional drainage increases contamination risk and should only be done under sterile conditions by a trained person when necessary; if done, steps to keep the roof intact are recommended.
- "Leave it open to air": Exposing an open blister to the environment increases contamination and may slow healing.
- "Apply ice directly to the blister": Direct ice can cause frost injury and is not helpful for an already ruptured blister; cold packs wrapped in cloth may reduce swelling but do not replace cleaning and dressing.

6) Conclusion
The recommended treatment for a popped blister is to clean it, bandage it, and do not remove the skin, which matches the provided answer: "Clean it, bandage it, and do not remove the skin."
