A contusion is a bruise, which is not a type of wound.

The first step in wound care is to clean the wound to remove any dirt, debris, or bacteria.

Applying pressure to a wound helps to stop bleeding by constricting the blood vessels.

Transparent film dressings are breathable and allow the wound to be monitored without removing the dressing.

The signs of infection in a wound include redness, swelling, pus, and pain.

The best way to prevent infection in a wound is to clean the wound thoroughly, apply a sterile dressing, elevate the wound, and take antibiotics if prescribed by a doctor.

A dressing should be left on a wound for 24 hours to allow the wound to heal properly.

Elevating a wound helps to reduce swelling, improve circulation, prevent infection, and promote healing.

The best way to care for a wound that is not healing properly is to clean the wound daily, apply a new dressing daily, elevate the wound, and see a doctor.

Pressure ulcers, diabetic ulcers, and venous ulcers are all types of chronic wounds.

Prolonged pressure on the skin, friction, and moisture are all leading causes of pressure ulcers.

Repositioning patients frequently, using pressure-relieving devices, and keeping the skin clean and dry are all effective ways to prevent pressure ulcers.

High blood sugar levels, nerve damage, and poor circulation are all leading causes of diabetic ulcers.

Controlling blood sugar levels, protecting the feet from injury, and wearing comfortable shoes are all effective ways to prevent diabetic ulcers.

Chronic venous insufficiency is the leading cause of venous ulcers.

Wearing compression stockings, elevating the legs, and exercising regularly are all effective ways to prevent venous ulcers.
