What are the causes of a pressure ulcer? (Select all that apply.)

Choice A reason: Providing active range of motion (ROM) is not a treatment that the nurse can perform for a quadriplegic client. Active ROM means that the client moves their own joints without assistance. A quadriplegic client has paralysis of all four limbs and cannot move their joints voluntarily.

Choice B reason: Providing passive range of motion (ROM) is a treatment that the nurse can perform for a quadriplegic client. Passive ROM means that the nurse moves the client's joints through their full range of motion without resistance. This helps prevent joint contracture, which is the loss of joint movement and flexibility due to muscle shortening and stiffness. It also helps maintain joint mobility, which is the ability of the joint to move smoothly and freely.

Choice C reason: Turning the client every 2 hours is not a treatment that the nurse can perform to decrease the risk of joint contracture and promote joint mobility. Turning the client every 2 hours is a preventive measure to avoid pressure ulcers, which are skin injuries caused by prolonged pressure on the skin. It does not directly affect the joint function or movement.

Choice D reason: Administering glucosamine supplements is not a treatment that the nurse can perform to decrease the risk of joint contracture and promote joint mobility. Glucosamine supplements are dietary supplements that may help reduce the pain and inflammation of osteoarthritis, which is a degenerative joint disease that causes the breakdown of the cartilage and bone in the joints. It does not affect the muscle or nerve function or movement.

Choice A reason: Fowler's position is a semisitting position with the head of the bed elevated at 45 to 60 degrees. This position allows for maximum expansion of the chest and improves ventilation and oxygenation. It also reduces the work of breathing and prevents the abdominal organs from compressing the diaphragm.

Choice B reason: Sim's position is a sidelying position with the lower arm behind the back and the upper knee flexed. This position is used for patients who are unconscious, have difficulty swallowing, or are receiving an enema. It does not facilitate breathing or oxygenation for patients with COPD.

Choice C reason: Prone position is a lying position with the face down and the arms at the sides or bent at the elbows. This position is used for patients with acute respiratory distress syndrome (ARDS) or severe lung injury to improve oxygenation and reduce lung inflammation. It is not recommended for patients with COPD as it may increase the risk of aspiration, pressure ulcers, and nerve damage.

Choice D reason: Lateral position is a sidelying position with the upper leg slightly flexed and supported by a pillow. This position is used for patients who are resting or sleeping to prevent pressure ulcers and promote comfort. It does not improve breathing or oxygenation for patients with COPD.
