What are the key modes of action for Hydrocolloids? (Select three correct answers from the below)

Raise the pH, reducing the ability of bacteria to proliferate.
Maintain dryness at the wound bed allowing for faster epithelialisation and lower levels of pain.
Prevent desiccation of the wound bed, providing a moist wound healing environment.
Lower the pH, reducing the ability of bacteria to proliferate.
Maintain moisture at the wound bed allowing for faster epithelialisation and lower levels of pain.

What is the definition of moisture vapour transfer rate?

The process whereby epidermal cells differentiate to form the stratum corneum.
Excessive production of granulation tissue.
The rate at which moisture passes through a dressing and evaporates into the atmosphere.
Promotion of angiogenesis.

True
False

What wound types should Larvae not be used on? (Select all that apply)

Wounds that may connect vital organs
Dry eschar

Larvae secrete a mixture of proteolytic enzymes to… (complete the statement)

Breakdown dead and devitalised tissue.
Promote granulation.
Manage exudate.

Honey is indicated for use in infected wounds. How does Manuka honey inhibit bacterial action?

The high sugar content of honey draws out lymph fluid and inhibits bacterial action.
There is a low concentration of slow-release hydrogen peroxide found naturally in honey, which inhibits bacterial action.
There is a good supply of protease enzymes in honey that inhibits bacterial action.

What are some advantages of PHMB? (Select three correct answers from the below)

Increases resistance
Excellent skin tolerance
Non-toxic, non-irritant
Non hypoallergenic
No known resistance

How is ionic silver released into a wound from a silver containing dressing?

In its metallic form, silver readily interacts with body tissues.
Silver dressings release silver in the presence of wound exudate as it ionises to release Ag+.
Silver dressings contain low concentrations of slow-release hydrogen peroxide, which helps them to release silver from the wound.

When selecting a silver dressing, which of the following should be taken into consideration? (Select two correct answers from the below)

It delivers silver in a sustained therapeutic way into the wound
Prophylactic use only
It can be used long term
It can be used on dry wounds

Topical negative pressure is indicated for the following wounds. (Select one correct answer)

Acute wounds, chronic wounds, pressure ulcers, malignant wounds, infected wounds.
Pressure ulcers, diabetic ulcers, chronic wounds, infected wounds.
