The three types of human error are

• A. Omission, Commission, and Negligence
• B. Omission, Commission, and Latent
• C. Omission, Commission, and Error
• D. Omission, Commission, and Extraneous

Answer: (D)

In clinical settings, human errors are often described by three kinds: omission, commission, and extraneous actions. An omission is failing to perform a required step, such as not giving a needed medication. A commission is taking an action that is incorrect or inappropriate, like administering the wrong drug or dose. An extraneous action is an unnecessary or superfluous step that isn’t required by the protocol and can complicate care or introduce risk, such as performing an extra test that wasn’t indicated. The other terms in the choices don’t fit this common classification: latent refers to hidden system conditions rather than a direct type of error, and negligence is a judgment about conduct rather than a distinct category of error.
