NKDA is an abbreviation used in patient care. What does it stand for?

• A. No known drug allergies.
• B. Not known drug administration.
• C. New kind of drug allergy.
• D. No knowledge of drug activities.

Answer: (A)

NkDA stands for No Known Drug Allergies. In patient care, documenting this means the patient has no reported or documented allergic reactions to medications, so clinicians can proceed with prescribed drugs with standard precautions, while still monitoring for any unexpected reactions. It’s important to distinguish allergies from other medication issues like side effects or intolerances, which are not true drug allergies. If no information is available, the status would be uncertain or require verification rather than labeling as having no known drug allergies.
