abrasion
laceration
puncture

Explanation:

Analyze the wound description

The question describes an injury where a sharp object, such as a knife or broken glass, slices through the layers of the skin, causing heavy bleeding. We need to identify which type of open wound this represents.

Define the options

Let's look at the definitions of the three types of wounds listed in the options:

• Abrasion: A scrape where the outer layer of skin is rubbed off, usually causing minimal bleeding (e.g., a skinned knee).
• Laceration: A deep cut or tear in the skin and flesh, typically caused by sharp objects like knives, glass, or metal, which often results in heavy bleeding.
• Puncture: A small, deep hole caused by a pointed object piercing the skin (e.g., a nail or needle), which may not bleed heavily but carries a high risk of infection.

Apply first aid concepts

Using our knowledge of First Aid Basics and Wound Care, we can match the description of a sharp object slicing through skin layers and causing heavy bleeding directly to a laceration.

Answer:

• abrasion
• laceration (Correct answer)
• puncture
