A nurse has received a change-of-shift report for four clients. Which of the following findings should the nurse report to the provider immediately?

Choice A reason: Difficulty recognizing objects (agnosia) is expected in dementia progression and does not require immediate reporting unless it leads to safety concerns. Choice B reason: Loss of interest (anhedonia) is a hallmark of depression but not an acute change requiring urgent intervention unless accompanied by suicidal ideation. Choice C reason: Rapid weight gain may indicate metabolic syndrome or fluid retention, but without other symptoms, it is not immediately life-threatening. Choice D reason: Decreased urine output in a client on lithium may signal nephrotoxicity or lithium toxicity. This is a potentially life-threatening complication requiring prompt evaluation.
