Safety factors involved in using an Aquathermia pad unit for a patient include (Select all that apply.)

Choice A rationale:

Sharp debridement involves the use of a sharp instrument or heat to remove dead tissue, which is not achieved with a hydrocolloid dressing.

Choice B rationale:

Chemical debridement involves the use of chemicals to remove dead tissue, which is not the function of a hydrocolloid dressing.

Choice C rationale:

Enzymatic debridement involves the use of enzymes to soften and remove dead tissue, which is not the function of a hydrocolloid dressing.

Choice D rationale:

Autolytic debridement uses the body’s own enzymes and moisture to soften and remove dead tissue. A hydrocolloid dressing helps maintain a moist wound environment, promoting autolytic debridement.

Choice A rationale:

An abrasion is a superficial injury to the skin caused by scraping or rubbing, which does not match the description of a pooling of blood under unbroken skin.

Choice B rationale:

An avulsion is a wound where a chunk of tissue is torn away, which does not match the description of a pooling of blood under unbroken skin.

Choice C rationale:

A hematoma is a pooling of blood outside of blood vessels, typically caused by trauma. It matches the description of a pooling of blood under unbroken skin.

Choice D rationale:

A laceration is a deep cut or tear in the skin, which does not match the description of a pooling of blood under unbroken skin.
