After practice, which method is described for draining a blister?

• A. Use a razor blade to cut along the bottom and let pus drain
• B. Squeeze until it bursts
• C. Apply pressure with nails
• D. Leave it untreated

Answer: (A)

The idea being tested is how a blister is described as being drained. The best option depicts creating an opening with a sharp instrument so the fluid can escape, which is the intended purpose of drainage—relieving pressure and removing the blister contents rather than letting it rupture uncontrolled or leaving it untreated. The other actions would either damage tissue and raise infection risk (squeezing until it bursts, or using nails) or do nothing to relieve the pressure and fluid buildup (leaving it alone). In real practice, drainage should be considered only with sterile technique and proper aftercare to protect the area.
