*

2

Autonomy

* This priciniple is fundamental in palliative care, emphasizing the patient's right to make decisions about treatment. - This includes choices & requires that the patient's wishes be respected, especially when quality of life is the primary focus.

5

Hydrogel dressings should be used for wounds with which of the following levels of exudate?

to support moist wound healing & facilitate autolytic debridement.

7

Autolytic debridement -

A natural wound-cleaning process that uses the body’s own enzymes & moisture to soften, liquefy, & remove dead (necrotic) tissue. It is considered the most conservative and selective method of debridement, meaning it breaks down only damaged or dead tissue while leaving healthy skin untouched

Class: 3

25-35 mm Hg

11
