A nurse is assessing a client's vital signs. The oxygen saturation is 85%. What intervention should the nurse perform first?

Choice A reason: This is not the priority assessment because peripheral edema is not a lifethreatening complication of immobility. Peripheral edema is the swelling of the lower extremities due to fluid accumulation. It can be caused by various factors, such as venous insufficiency, heart failure, kidney disease, or medication side effects. The nurse should monitor the client's fluid status and provide elevation and compression therapy as needed.

Choice B reason: This is the priority assessment because lung sounds can indicate the presence of respiratory complications, such as pneumonia or atelectasis, which are common and serious consequences of immobility. Pneumonia is an infection of the lungs that causes inflammation, mucus production, and impaired gas exchange. Atelectasis is the collapse of alveoli, which are the tiny air sacs in the lungs that facilitate oxygen and carbon dioxide exchange. The nurse should auscultate the client's lung sounds regularly and report any abnormal findings, such as crackles, wheezes, or diminished breath sounds. The nurse should also encourage the client to cough, deep breathe, and use incentive spirometry to prevent or treat respiratory problems.

Choice C reason: This is not the priority assessment because bowel sounds can reflect the status of the gastrointestinal system, which is not directly affected by immobility. Bowel sounds are the noises produced by the movement of food and gas through the intestines. They can vary in frequency and intensity depending on the client's diet, activity, and medications. The nurse should auscultate the client's bowel sounds and assess for any signs of constipation, diarrhea, or obstruction. The nurse should also promote the client's bowel function by providing adequate hydration, fiber, and laxatives as ordered.

Choice D reason: This is not the priority assessment because skin turgor can indicate the level of hydration, which is not a primary concern of immobility. Skin turgor is the elasticity of the skin that allows it to return to its normal shape after being pinched or pulled. It can be affected by factors such as age, weight loss, dehydration, or edema. The nurse should assess the client's skin turgor and provide adequate fluids and electrolytes as needed. The nurse should also pay attention to the client's skin integrity and prevent or treat any pressure ulcers or wounds that may result from immobility.

Choice A reason: A 44yearold prescribed antibiotics for pneumonia is not at the greatest risk for pressure injury development, because he or she does not have any major risk factors for pressure injury. Pressure injury is a localized damage to the skin and underlying tissues caused by pressure, shear, friction, or moisture. Antibiotics for pneumonia do not directly affect the skin integrity or blood circulation, nor do they impair the mobility or sensation of the client.

Choice B reason: A 26yearold bedridden client with a fractured leg is at a high risk for pressure injury development, but not the greatest, because he or she has only one major risk factor for pressure injury. Bedridden status is a major risk factor for pressure injury, because it causes prolonged pressure on the bony prominences, such as the sacrum, heels, or hips, which can impair blood flow and oxygen delivery to the skin and tissues. However, the client's age, fracture, and mobility may mitigate some of the risk, as he or she may have better skin elasticity, wound healing, and ability to reposition.

Choice C reason: A 65yearold with hemiparesis and incontinence is at the greatest risk for pressure injury development, because he or she has multiple major risk factors for pressure injury. Age is a risk factor for pressure injury, because it causes decreased skin elasticity, thickness, and vascularity, which can affect the skin's resilience and repair. Hemiparesis is a risk factor for pressure injury, because it causes reduced mobility, sensation, and muscle mass, which can affect the client's ability to reposition, feel pain, and maintain tissue perfusion. Incontinence is a risk factor for pressure injury, because it causes moisture, irritation, and infection of the skin, which can weaken the skin barrier and delay wound healing.

Choice D reason: A 78yearold requiring assistance to ambulate with a walker is at a moderate risk for pressure injury development, but not the greatest, because he or she has only one major risk factor for pressure injury. Age is a risk factor for pressure injury, as explained above. However, the client's ambulation and assistance may reduce some of the risk, as he or she may have less pressure, shear, and friction on the skin and tissues, and more blood circulation and oxygen delivery.
