Allied Health Certified Nursing Assistant (CNA) Practice Test

VS stands for vital signs—the basic measurements that show how well the body is functioning. Vital signs usually include blood pressure, pulse, respirations, oxygen saturation, and temperature. They’re used together to assess a patient’s stability and to detect changes over time, guiding both routine care and urgent interventions. The other terms refer to different ideas (the vascular system, fluid balance in the body, or an unaffiliated visual check) and aren’t what VS represents in clinical shorthand.
