What are exceptions to WDL?

WDL means within defined limits: the finding matches the normal criteria your facility has defined for that assessment. WNL means within normal limits. An exception is a finding outside those criteria. Charting by exception spares you from rewriting normal findings every time, but each exception needs its own entry: what you found and when, what you did, who you told, and how the patient responded.

Charting by exception saves you from describing defined normal findings over and over. But a WNL checkbox alone may not show what changed, who you told, what you did, or whether the patient improved.

Key points

  • Know what the checkbox covers. Check your facility’s definitions of WNL and WDL before you use them.
  • Keep required measurements in the record. A normal label does not replace required vital signs, intake and output, or other measured values.
  • Separate baseline from normal. Unchanged does not mean normal. An abnormal finding may still need documentation.
  • Close the loop on changes. Record the finding, time, what you did, what you communicated, and your reassessment.
  • Make every assessment current. Don’t mark an area normal if you haven’t assessed it. Check any carried-forward content against your current assessment and follow facility policy.

What to write

These are fictional charting examples, not excerpts from the cases or notes to paste into a chart. Use only findings you actually assessed and actions that actually happened. Follow the patient’s needs, orders, and facility policy when deciding when to assess or escalate.

The right column shows the information the record needs. If you’ve already captured it in the appropriate flowsheet or MAR, you don’t need to repeat it in a paragraph.

as written

VS WNL.

as it holds up

0800: BP 128/74 mm Hg, HR 78/min, RR 16/min, temperature 36.8°C oral, SpO₂ 97% on room air.

as written

Neuro WNL. No change.

as it holds up

0800: Alert; oriented to person, place, date, and situation. Left grip weaker than right, unchanged from documented admission assessment. Speech clear; no facial droop.

as written

Surgical site WNL.

as it holds up

1400: Lower abdominal dressing intact with 3 × 2 cm area of serosanguineous drainage, unchanged from 1200. Incision not visualized beneath dressing.

as written

Respiratory WDL except shortness of breath. Provider aware.

as it holds up

0900: Dyspnea with transfer to chair. RR 24/min; SpO₂ 90% on room air, decreased from 96% at 0800. Returned to bed; head of bed elevated. 0903: NP Rivera notified of new dyspnea, respiratory rate, and SpO₂ decline. 0905: Oxygen started at 2 L/min by nasal cannula per new order. 0910: RR 20/min; SpO₂ 95% on 2 L/min. Patient denies dyspnea at rest.

as written

Pain WNL after PRN.

as it holds up

1300: Incisional pain 6/10 at rest. 1305: Acetaminophen 650 mg PO given per PRN order; administration recorded in MAR. 1400: Pain 2/10 at rest. Patient able to turn in bed without stopping because of pain.

Look at what those entries add:

  • The vital-sign entry gives values, not just your judgment about them.
  • The neurologic entry keeps the abnormal baseline visible instead of calling it normal.
  • The dressing entry says what you could not assess: the incision was not seen.
  • The respiratory entry links the change to notification, treatment, and reassessment.
  • The pain entry shows the reported score and what the patient could do afterward.

No full head-to-toe narrative needed. Each entry fills in the specific information the shorthand leaves out.

Words to avoid

These terms are not wrong by themselves. The problem is using them in place of details the reader needs.

Word or phrase Why it falls short Replace it with

One checkbox that cannot tell the whole story

One checkbox cannot tell the whole patient story. The mistake is expecting it to.

WNL generally means within normal limits; WDL means within defined limits. What you document by selecting either one depends on the assessment definitions and workflow behind it. When that selection is properly defined, it can capture normal findings without a duplicate narrative.

But sometimes the record needs more:

  • Scope: Did you inspect the incision, or only the dressing?
  • Trend: Was the finding normal, or just unchanged from an abnormal baseline?
  • Timing: When did the symptom start, and when did you reassess the patient?
  • Response: What happened after the medication, intervention, or notification?

A blank field is not automatically a normal entry, either. Whether it means anything depends on the documentation system, not on what someone reading the chart assumes.

You don’t need more words everywhere. You need enough information to connect assessment → action → response where that connection matters.

Bottom line

WNL can sum up defined normal findings. It cannot replace the record of what changed for your patient, what you did, and what happened next.

Official guidance

  • Use exception charting to avoid describing routine normal findings over and over. (Med League, GetIndigo)

In court, 1994–2018

What happened in 2 court cases

Lama Romero v. Asociacion: U.S. Court of Appeals for the First Circuit, 1994.

After spinal surgery, nursing notes documented bloody or soiled dressings and incision-site pain. The opinion explained that the hospital’s exception-charting approach gave a less complete picture of the patient’s changing condition: nurses recorded qualitative observations only when changes were important. They still recorded routine quantitative data, including temperature.

The First Circuit affirmed the malpractice verdict against the physician and hospital. It agreed with the trial court’s reasoning that the way the records were kept could support a finding of careless postoperative monitoring. That decision was about this hospital’s records and care. It did not reject every CBE system.

Michael Miller v. Lone Star HMA, L.P., and Mesquite HMA General, LLC: Texas Court of Appeals, Fifth District, Dallas, 2018.

Miller alleged that insufficient nursing documentation of surgical-wound drainage contributed to his premature discharge. But no evidence established what the missing drainage information would have shown.

The court upheld the exclusion of the causation expert’s testimony as unsupported and speculative. With no other causation evidence left, it affirmed summary judgment for the hospital entities. The missing piece was evidence connecting the alleged charting omissions to the injury. The ruling did not mean the undocumented observations were normal.

  • Most Epic layouts will have an initial box to mark the system as either WNL or "WNL Except", and then other boxes for detailed assessment findings.

  • If you’re doing the assessments and nothing is changing, there should be no problem with pasting over your own documentation. If you’re copying someone else’s charting, that’s risky behavior because you don’t know for certain what they assessed or if they assessed at all.

  • So if only one thing came up abnormal and the rest of that section in the assessment is WDL they can absolutely still put the WDL in that section but also chart the exception. It’s really the nurses discretion even though it’s more charting than necessary.
