A water hating, non absorbent dressing

Question 27

Hyper-granulation (overgranulation)

Answer 27

Excessive production of granulation tissue

Question 28

Infection

Answer 28

Caused by micro-organisms which evade the immunological defences, enter and establish themselves within the tissues

Question 29

Inflammation

Answer 29

Natural defence against bacterial invasion, stimulates wound healing

Question 30

Localised deficiency of arterial blood

Question 31

Keratinised

Answer 31

The process whereby epidermal cells differentiate to form the stratum Corneum

Question 32

Leg ulcer

Answer 32

Wound of the lower limb that is chronic in nature

Question 33

Maceration

Answer 33

Softening of tissue that has remained moist or wet for a long period. The skin becomes white and soggy and less resilient. Can predispose to tissue breakdown

Question 34

Malnutrition

Answer 34

Poor nutritional status from impaired absorption,

Question 35

Mannurotic acid

Answer 35

Present in alginates, form a soft flexible gel, breaks down in the presence of sodium and rinses away

Question 36

Moisture vapour transfer rate (MVTR)

Answer 36

The rate at which moisture (mainly from wound exudate) passes through a dressing and evaporates into the atmosphere

Question 37

Necrosis

Answer 37

Death of tissue or organ in response to injury, disease or occlusion of blood flow

Question 38

Oedema

Answer 38

An unnatural accumulation of fluid in the interstitial spaces

Question 39

Pressure ulcer

Answer 39

An area of localised damage to skin and underlying tissue caused by pressure, shear and friction.

Question 40

Proliferation phase

Answer 40

Third phase of wound healing, intense proliferation of fibroblasts and endothelial cells.

Question 41

Pus

Answer 41

A production of inflammation usually caused by infection containing used cells, debris and tissue elements

Question 42

Sharp Debridement

Answer 42

Method of Debridement using scalpel or scissors to remove necrotic tissue.

Question 43

Sinus

Answer 43

An epithelial cell lined tube from the outside of the body to the inside.

Question 44

Slough

Answer 44

A mixture of dead white cells, dead bacteria, rehydrated necrotic tissue and fibrous tissue.

Question 45

Tissue Viability

Answer 45

The ability if tissue to perform it's function optimally.

Question 46

Vapour permeable

Answer 46

Gases and water vapour can pass through e.g. Dressing surface.

Question 47

Vasoconstriction

Answer 47

The arteries and arterioles constrict under the influence of drugs, hormones or cold.

Question 48

Vascularity

Answer 48

Blood supply to an area of tissue

Answer 49

May be dilation or contraction, in a response to a variety of stimuli e.g. Temperature, inflammatory state and blood volume.

Question 50

Vasodilation

Answer 50
