The abbreviation ACT is defined as which of the following in the material?

• A. Activated clotting time
• B. To do
• C. Anticoagulation therapy
• D. Act

Answer: (B)

In this material, abbreviations are used as labels for actions that need to be taken. ACT is defined as “To do,” so it signals a task item rather than a clinical term or policy. This makes it the best fit because the context treats ACT as a prompt to perform an action on the care plan or checklist.

The other meanings don’t align with how the material uses ACT: you’d expect activated clotting time to refer to a lab test result, anticoagulation therapy to describe a treatment, or simply “Act” as a word, none of which function as a task label in this context. So sticking with “To do” matches how ACT is presented and used in the material.
