What it means
Written on the chart, the wristband record and the medication record when a client says they are not allergic to any drug. NKA (no known allergies) also covers food, latex and other things.
For the nurse
Ask about allergies to drugs, latex and foods (and what reaction happened) before any medicine is given, even when the chart already says NKDA.
