The abbreviation NKDA expands to which of the following?

• A. No Known Allergies
• B. No Known Drug Allergies
• C. Not Known Drug Allergies
• D. Not Known Allergies

Answer: (B)

NKDA expands to No Known Drug Allergies. This standard phrasing tells clinicians that the patient has no documented allergic reactions to medications, guiding safe use of drugs in prehospital care. The other options aren’t used in practice and can be unclear or misleading, because they either sound awkward or could imply allergies to non-drug substances. Remember that “no known drug allergies” doesn’t guarantee there will be no reaction—always review the patient’s history and monitor after administering any medication.
