What should be done if a large blister has formed?

1. Puncture and drain the blister, then apply dressing

2. Leave the blister intact and cover with a bandage

3. Apply ice to reduce swelling

4. Use antibiotic ointment without draining

The correct answer is: Puncture and drain the blister, then apply dressing

When dealing with a large blister, the recommended approach is to puncture and drain it properly, then apply a dressing. This method is advisable for several reasons. Firstly, large blisters can be quite painful and may hinder mobility. By draining the blister, you alleviate pressure and discomfort, thus improving the person's ability to move affected areas more comfortably. Secondly, proper drainage of the blister reduces the risk of further trauma that could cause it to burst on its own. When a blister bursts naturally, it can lead to increased pain and a greater risk of infection due to exposure to environmental elements. Moreover, after puncturing the blister, it's crucial to maintain cleanliness and cover it with a sterile dressing. This protects the area and promotes healing while preventing potential pathogens from entering the site, thereby reducing the risk of infection. In contrast, leaving the blister intact could preserve some degree of natural protection, but it can also result in further pain or complicate movement. Other options like applying ice might minimize swelling but do not address the blister itself, and using antibiotic ointment without draining does not allow the wound to heal effectively. Hence, puncturing and draining followed by appropriate wound care is the correct and more effective approach.
