A nurse reviews the electronic health record of a client who has acute kidney injury (AKI). Which documentation would alert the nurse to urgently contact the primary health care provider for additional prescriptions?

Choice A reason: A poor appetite (anorexia) is a common symptom in patients with renal failure due to the buildup of metabolic waste products (uremia). While this requires nutritional intervention and monitoring over time, it is not an acute emergency that requires an "urgent" contact with the healthcare provider. Choice B reason: A weight decrease of 3 lb in a patient with AKI is often a positive sign, particularly if the patient was previously in the oliguric phase with fluid retention. It likely indicates the diuretic phase of recovery, though the nurse should monitor for dehydration and electrolyte shifts associated with this weight loss. Choice C reason: A white blood cell count of 8200/mm3 falls within the normal reference range (5000 to 10000/mm3). This suggests that the patient does not currently have a systemic infection, which is a common complication of AKI. Since this is a normal finding, no urgent action is required. Choice D reason: A serum potassium level of 2.6 mEq/L indicates severe hypokalemia (normal: 3.5 to 5.0 mEq/L). In AKI, this can occur during the diuretic phase as the kidneys lose the ability to concentrate urine. Severe hypokalemia can lead to life-threatening cardiac arrhythmias and requires immediate replacement therapy and cardiac monitoring.
