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

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.

Choice A reason: Nociceptive pain is not the type of pain that the client is experiencing. Nociceptive pain is caused by the stimulation of nociceptors, which are sensory receptors that detect tissue damage or potential harm. Nociceptive pain is usually localized, sharp, throbbing, or aching. It is associated with injuries such as cuts, burns, sprains, or fractures. The client's pain is not caused by any tissue damage or harm in the distal part of the amputated limb, as there is no tissue left there.

Choice B reason: Neuropathic pain is the type of pain that the client is experiencing. Neuropathic pain is caused by the damage or dysfunction of the nervous system, such as the peripheral nerves, the spinal cord, or the brain. Neuropathic pain is usually chronic, burning, shooting, or tingling. It is associated with conditions such as diabetes, shingles, stroke, or amputation. The client's pain is caused by the disruption of the nerve signals from the amputated limb, which creates a phantom sensation of pain in the missing part.

Choice C reason: Cutaneous pain is not the type of pain that the client is experiencing. Cutaneous pain is caused by the stimulation of the cutaneous receptors, which are sensory receptors that detect touch, temperature, or pressure on the skin. Cutaneous pain is usually superficial, brief, or pricking. It is associated with stimuli such as pinching, scratching, or cold. The client's pain is not caused by any touch, temperature, or pressure on the skin of the distal part of the amputated limb, as there is no skin left there.

Choice D reason: Visceral pain is not the type of pain that the client is experiencing. Visceral pain is caused by the stimulation of the visceral receptors, which are sensory receptors that detect stretch, inflammation, or ischemia in the internal organs. Visceral pain is usually deep, dull, or cramping. It is associated with conditions such as appendicitis, pancreatitis, or bowel obstruction. The client's pain is not caused by any stretch, inflammation, or ischemia in the internal organs of the distal part of the amputated limb, as there are no organs left there.
