What is indicated by the abbreviation "NKDA"?

The abbreviation "NKDA" stands for "No Known Drug Allergies." This term is commonly used in medical documentation to indicate that a patient does not have any known allergies to medications, which is crucial information for healthcare providers when prescribing treatments. Knowing there are no known drug allergies helps to minimize the risk of adverse reactions and complications during medical care. This information is especially important prior to administering medications or anesthesia, as it informs the medical team about what substances can safely be used without causing an allergic reaction.

The other options represent different medical terms or abbreviations but do not accurately define "NKDA." For example, one option relates to a form of diabetes, while another option pertains to a physical exam finding. In this context, the correct interpretation of "NKDA" directly relates to a patient's drug allergy history, making option B the most appropriate choice.
