Priority: Unexpected vs Expected Findings
Overview
An unexpected finding is any assessment result, lab value, or change in condition that deviates from what is predicted for the patient's diagnosis, treatment, or baseline. Prioritizing the unexpected is a distinct skill from ABCs or Maslow: you compare actual data against expected data and act on the mismatch. On 'which patient do you assess first' questions where everyone seems stable, the answer is the patient whose finding does not fit the clinical story. Expected findings get monitored; unexpected findings get acted on now.
Interpretation
Ask three questions in order: (1) What should I expect for this diagnosis and timeframe? (2) Does this data match? (3) If not, it is the priority. Watch the trap of picking the sickest-sounding patient or the highest absolute lab number instead of the patient whose finding deviates from the expected trajectory.
Compare Expected Unexpected
Same body system, opposite priority — the difference is whether the finding fits the expected trajectory.
Expected (monitor) vs Unexpected (act/report now)
Expected — monitor
- T-tube drainage (post-cholecystectomy)
- Dark green bile draining
- Post-op fever
- Day 1 low-grade temp, clear lungs (atelectasis)
- Post-thyroidectomy neck
- Mild sore throat, incisional pain
- Potassium trend
- Mild K+ 3.2 mEq/L, stable, no deterioration
- Blood glucose
- Glucose 210 mg/dL on new high-dose steroid
- WBC / blood counts
- Chemo day-10 WBC nadir, afebrile
Unexpected — report now
- T-tube drainage (post-cholecystectomy)
- Bright red drainage 75 mL over 2 hr (possible hemorrhage)
- Post-op fever
- Day 3 fever 102.1°F with purulent wound drainage (SSI)
- Post-thyroidectomy neck
- New stridor and throat tightness (airway/hematoma)
- Potassium trend
- K+ 6.1 mEq/L on ACE inhibitor, up from 4.2 (dysrhythmia risk)
- Blood glucose
- Glucose 42 mg/dL, missed meal (severe hypoglycemia)
- WBC / blood counts
- WBC 0.8 with fever 101°F — neutropenic fever, sepsis risk
Technique
Clinical Pearl
Expected findings can wait; the new or unexpected change is the one you assess and report first — 'Is this normal for them right now?' is the triage question.
