Pressure Ulcer Staging and Characteristics

The video provides an introduction to pressure ulcers, explaining the recent change in terminology from 'pressure ulcer' to 'pressure injury'. It details the anatomy of skin layers and the stages of pressure ulcers, from stage 1 to stage 4, based on tissue exposure. The rationale behind staging is discussed, emphasizing the importance of tissue type over depth. The video also covers the types of tissues visible in different stages and considerations for accurate staging, including special cases like exposed cartilage or tendons.

What recent change was made to the terminology regarding pressure ulcers?

• From 'pressure sore' to 'pressure wound'

• From 'pressure ulcer' to 'pressure injury'

• From 'pressure wound' to 'pressure sore'

• From 'pressure injury' to 'pressure ulcer'

Which layer of skin is directly beneath the epidermis?

• Bone

• Dermis

• Muscle

• Hypodermis

At which stage of pressure ulcer is the subcutaneous layer exposed?

• Stage 3

• Stage 1

• Stage 2

• Stage 4

What is a characteristic of Stage 1 pressure ulcers?

• Disruption of the dermis

• Exposure of muscle

• Non-blanchable erythema of the epidermis

• Exposure of bone

Why are pressure ulcers not typically geometric in shape?

• They are always rectangular

• They are carved by natural forces

• They are man-made

• They are symmetrical

Which tissue type is visible in Stage 2 pressure ulcers?

• Bone

• Muscle

• Cartilage

• Dermis

What determines the stage of a pressure ulcer?

• The type of tissue exposed

• The depth of the ulcer

• The size of the ulcer

• The location of the ulcer

Why might a shallow ulcer over the coccyx be classified as Stage 4?

• Because of its size

• Because of the tissue type exposed

• Because of its depth

• Because of its location

What is the significance of the subcutaneous layer in pressure ulcer staging?

• Its exposure indicates Stage 4

• Its exposure indicates Stage 3

• Its exposure indicates Stage 2

• Its exposure indicates Stage 1

What is the primary factor in determining the stage of a pressure ulcer?

• The ulcer's depth

• The ulcer's color

• The ulcer's location

• The type of tissue exposed
