Wound Care and Oxygen Safety

A set of flashcards covering key concepts related to wound care and oxygen safety.

What is a wound?

A wound is a break in the skin or mucous membrane.

What are some common causes of wounds?

Surgery, trauma, unrelieved pressure or friction, decreased blood flow, and nerve damage.

What does 'constrict' mean?

To narrow.

What is a skin tear?

A skin tear is a break or rip in the outer layer of the skin.

Why are the elderly at higher risk for skin tears?

Their skin can be as thin as tissue paper.

How can skin tears be prevented?

Prevent friction and shearing, keep skin moisturized, and handle carefully.

What are circulatory ulcers?

Ulcers found on lower legs and feet caused by decreased blood flow.

What are venous ulcers?

Open sores on the lower legs or feet caused by poor venous return.

What are arterial ulcers?

Open wounds on the lower legs or feet caused by poor arterial blood flow.

What are diabetic foot ulcers?

Open wounds on the foot caused by complications from diabetes.

What is the purpose of elastic stockings?

To put pressure on veins, promoting venous blood flow and preventing blood clots.

What are the functions of wound dressings?

Protect wounds, absorb drainage, remove dead tissue, promote comfort, cover wounds, and apply pressure to control bleeding.

What precautions should you take when securing a dressing with tape?

Tape the top, middle, and bottom of the dressing securely.

What are the effects of applying heat?

Relieves pain, relaxes muscles, promotes healing, reduces swelling, and decreases joint stiffness.

What complications can arise from heat applications?

Burns and constriction of blood vessels, leading to decreased blood flow.

What is the primary use of cold applications?

To treat sprains and fractures, reduce pain, prevent swelling, and decrease bleeding.

What complications can arise from cold applications?

Burns, pain, blisters, and poor circulation.

What is the normal range for respirations?

12-20 per minute.

What device measures oxygen concentration in the blood?

Pulse oximetry.

What is a nasal cannula?

A device with prongs inserted into the nose to deliver oxygen.

Why is oxygen considered a drug?

It must be administered with caution, and C.N.A.s cannot change the flow rate or discontinue oxygen.
