Expected versus unexpected, acute versus chronic
Two traces running below a dashed textbook-normal line, one flat and chronic across five days, one identical until it breaks sharply downward on day four.
| Client | Expected for this diagnosis | Unexpected for this diagnosis |
|---|---|---|
| First day after abdominal surgery | Incisional pain, diminished bowel sounds, guarding on movement | Absent bowel sounds with a rigid abdomen and a climbing heart rate |
| Long-standing chronic obstructive pulmonary disease | Barrel chest, clubbed fingers, chronically retained carbon dioxide, pursed-lip breathing | A sudden drop in level of consciousness |
| Cirrhosis with ascites | Long-standing abdominal distension, dependent edema, visible abdominal veins | New confusion with asterixis, suggesting rising ammonia |
| Sickle cell crisis | Severe pain requiring scheduled analgesia | Priapism, or any sudden change in neurologic status |
| Second day after total hip arthroplasty | Ecchymosis around a healing incision, activity-limited discomfort | Sudden pleuritic chest pain with new dyspnea |
What it changes
Expected findings are documented, monitored, and taught about. Unexpected findings are assessed further and escalated. An acute change layered onto a chronic condition is treated as acute, full stop. The presence of a chronic abnormality never earns a new abnormality the benefit of the doubt, and a client whose baseline is already poor has less reserve, not more.
Margin noteabnormal is not the question, different is the question.
Watch outA client with an abnormal baseline can deteriorate while every value still looks bad in exactly the way it always looked bad. Compare against yesterday's chart, not against the textbook.
TakeawayThe exam rewards deviation from this client's expected trajectory, not deviation from a textbook normal. → BOOK 07 · P3 · → BOOK 09 · P5 · → BOOK 11 · P3
