Which abbreviation stands for No Known Drug Allergies?

• A. Abx
• B. NKDA
• C. IVF
• D. RUQ

Answer: (B)

In medical documentation, allergy information is summarized with commonly used abbreviations. NKDA stands for No Known Drug Allergies, meaning there are no suspected or documented allergic reactions to medications at this time. This is why it’s the best answer: it directly conveys the absence of drug allergies, which is essential for safe prescribing.

Abx is a standard shorthand for antibiotics, referring to a class of medications themselves, not the patient’s allergy status. IVF stands for in vitro fertilization, a reproductive technology, not related to allergies. RUQ denotes the right upper quadrant of the abdomen, an anatomical region, not allergy information.
