A nurse is caring for a client with acute kidney injury (AKI). Which assessment finding warrants immediate intervention?

Choice A reason: Reports of a bad taste in the mouth can be associated with various conditions, including metabolic imbalances, but it is not typically an immediate concern in the context of AKI.

Choice B reason: Low concentrated urine output (oliguria) is a common finding in AKI and indicates decreased kidney function. While it is an important assessment finding, it does not usually require immediate intervention compared to signs of severe complications.

Choice C reason: Dyspnea (difficulty breathing) and sinus tachycardia (rapid heart rate) can indicate fluid overload or pulmonary edema, which are serious complications of AKI. These symptoms require immediate intervention to prevent respiratory distress and potential cardiac complications.

Choice D reason: A productive cough and fever may suggest an infection, which is important to address but not necessarily an immediate life-threatening issue compared to dyspnea and tachycardia in the context of AKI.

Choice A reason: An exit site infection can occur around the catheter insertion site, leading to redness, tenderness, and drainage. While this is a concerning issue that needs to be addressed, the more significant complication to prevent is peritonitis, which can result from an exit site infection if it spreads.

Choice B reason: Peritonitis is a serious and potentially life-threatening infection of the peritoneal cavity. In clients on peritoneal dialysis, signs such as redness, tenderness, and drainage around the catheter site are alarming indicators that could lead to peritonitis if not promptly treated. Peritonitis can cause severe abdominal pain, fever, and cloudy dialysis fluid, and requires immediate medical intervention to prevent complications.

Choice C reason: Outflow obstruction is a complication where the peritoneal dialysis fluid does not drain properly. This can be caused by a number of issues including catheter malposition or blockages, but it is not directly related to the symptoms of redness, tenderness, and drainage at the catheter site. Outflow obstruction is important to monitor but does not represent the immediate risk that peritonitis does.

Choice D reason: Atelectasis refers to the collapse of a part or all of a lung, often due to blockage of the air passages. This is not related to the symptoms around the peritoneal dialysis catheter site. While respiratory issues must be monitored, the primary concern here is the potential for peritoneal infection.
