1. What are the four main types of wounds and how are they classified?

- The four main types of wounds are incisions, lacerations, punctures, and

avulsions. They are classified according to the cause, depth, and extent of

tissue damage.

- Incisions are clean cuts made by sharp objects, such as knives or scissors.

They have smooth edges and minimal tissue loss.

- Lacerations are irregular tears or splits in the skin or underlying tissues

caused by blunt force trauma, such as falls or accidents. They have jagged

edges and may involve significant tissue loss or damage.

- Punctures are small holes or openings in the skin or underlying tissues

caused by sharp objects, such as needles or nails. They have narrow entry

points and may penetrate deep into the body.

- Avulsions are partial or complete detachments of the skin or underlying

tissues caused by tearing or shearing forces, such as explosions or animal

bites. They have large exit points and may expose bones, muscles, or

organs.

2. What are the signs and symptoms of wound infection and what are the

appropriate interventions?

- The signs and symptoms of wound infection include redness, swelling,

warmth, pain, pus, foul odor, fever, and increased drainage. The appropriate

interventions include cleaning the wound with sterile saline or water, applying

topical antibiotics or antiseptics, dressing the wound with sterile gauze or

bandages, elevating the affected area, administering systemic antibiotics or

analgesics as prescribed, monitoring vital signs and wound healing, and

educating the patient on wound care and prevention of infection.

3. What are the principles of pressure ulcer prevention and management?

- The principles of pressure ulcer prevention and management are to identify

and eliminate the sources of pressure, friction, and shear; to assess and

monitor the skin for signs of breakdown; to maintain adequate nutrition and

hydration; to reposition the patient at least every two hours; to use pressure-
