Which term describes a device or instrument used in practice?

• A. Diagnosis
• B. Discrete
• C. Distal
• D. Device

Answer: (D)

Understanding how terms describe what is used in a clinical setting helps with these kinds of questions. The term that refers to a device or instrument used in practice is the one that names tools involved in care, such as a thermometer, stethoscope, or surgical instrument. This term fits because it directly denotes an item designed for use in performing tasks or delivering care. The other options don’t describe tools: one relates to identifying illness (diagnosis), one means separate or distinct (discrete), and one is a directional term meaning farther from a point of reference (distal).
