Creatinine doubles, but the lab does not flag it. Would you catch the change? Nora connects three original adult cases with AKI recognition, baseline comparisons, urine-output math, supply–filter–drain causes, fluid assessment, medicine safety, urgent complications and recovery. Slow, friendly teaching, simple analogies, repeated cues and eight pause-and-answer checks make the kidney story easier to follow. Recaps Episode 16 and previews a planned gastrointestinal bleeding review.

• Compare the change: a creatinine inside the lab interval can still represent an acute doubling from baseline.
• Check the flow: interpret urine output with weight, time and measurement accuracy; do not wait for a diagnostic interval to assess deterioration.
• Watch the whole person: assess supply, filter and drain; fluid tolerance, medicines, complications and recovery determine the response.
