A client with acquired immunodeficiency syndrome (AIDS) has Pneumocystis carinii (PCP). What is the nurse's priority assessment for this client?

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: An event that can cause serious injury to a client that should never happen in a hospital is not the best description of a sentinel event, because it is too vague and broad. It does not specify the degree of injury or the nature of the event. It also implies that some events that cause serious injury are acceptable in a hospital, which is not true.

Choice B reason: Specific events that enable a hospital to maximize reimbursement is not a description of a sentinel event, but rather a description of quality indicators or performance measures. These are criteria that reflect the quality of care provided by a hospital and affect its payment from payers. They are not related to sentinel events, which are adverse events that require immediate investigation and response.

Choice C reason: An unexpected event involving death or serious physical or psychological injury is the best description of a sentinel event, because it captures the essence and severity of the event. According to the Joint Commission, a sentinel event is "an unexpected occurrence involving death or serious physical or psychological injury, or the risk thereof" . Examples of sentinel events include wrongsite surgery, medication error, suicide, or abduction.

Choice D reason: Operating room event involving the use of unsafe equipment is not a description of a sentinel event, but rather an example of a potential sentinel event. It is not a general definition that applies to all sentinel events, but a specific scenario that may or may not result in death or serious injury. It also does not indicate the unexpectedness of the event, which is a key characteristic of a sentinel event.
