Chronic Wound Healing Aids

Which of the following best describes the main purpose of Negative Pressure Wound Therapy (NPWT) in treating chronic wounds?

• To increase the amount of fluid in the wound

• To remove excess fluid and promote healing

• To introduce more destructive molecules into the wound

• To prevent the formation of granulation tissue

Why do some chronic wounds become stalled in the healing process, according to the provided material?

• They lack exposure to air

• They are too dry for healing to occur

• They remain in the inflammatory phase due to destructive molecules

• They are exposed to too much sunlight

Explain how the imbalance of molecules in chronic wounds affects the healing process, based on the information provided.

• High levels of growth factors speed up healing

• Low levels of proteases help build the extracellular matrix

• High levels of destructive molecules and low levels of growth factors impede healing

• Excess fluid in wounds always promotes faster healing

What is the role of the extracellular matrix in wound healing, as described in the material?

• It prevents fluid from leaving the wound

• It is the foundation of healthy granulation tissue

• It increases the inflammatory response

• It destroys proteases in the wound

What is the function of the device shown in the image in the context of wound healing?

• To add moisture to the wound

• To apply negative pressure and remove excess fluid

• To inject growth factors directly into the wound

• To increase the temperature of the wound

Which of the following best describes the primary function of negative-pressure dressings in wound care?

• They add moisture to the wound to speed up healing.

• They remove excess fluid from wounds, improving healing time.

• They inject antibiotics directly into the wound.

• They are used only to cover wounds without any additional function.

What is the main purpose of the special plastic film used in negative-pressure wound therapy (NPWT)?

• To provide nutrients to the wound.

• To keep the wound dry by absorbing all fluids.

• To seal the wound from the environment and protect it from contaminants.

• To make the dressing easier to remove.

Explain how the vacuum mechanism in negative-pressure wound therapy (NPWT) contributes to wound healing. Use evidence from the process described to support your answer.

• The vacuum injects medication into the wound, which directly kills bacteria.

• The vacuum pulls the plastic film tightly over the wound, sealing it and continuously removing fluid, which protects the wound and keeps it warm.

• The vacuum only serves to keep the dressing in place.

• The vacuum increases blood flow by massaging the wound.

A patient is being treated with a negative-pressure dressing. What would likely happen if the plastic film was not sealed tightly over the wound?

• The wound would heal faster due to increased air exposure.

• The wound would be protected from contaminants, but fluid would not be removed.

• The wound would be exposed to outside contaminants, and the vacuum would not effectively remove fluid.

• The dressing would still work as intended.

A patient with a heavily exudating wound is being treated with NPWT. According to standard practice, how often should the dressing typically be changed?

• Every 24 hours

• Every 48–72 hours

• Once a week

• Every 10 days
