Wisconsin CNA State Exam Vocabulary Practice

What is defined as any device or system that can take over for a vital body organ or function that is failing or has failed?

1. Life Support

2. Lift/Draw Sheet

3. Living Will

4. Log Roll

The correct answer is: Life Support

The correct answer is life support, which refers to a range of medical interventions and devices designed to sustain vital bodily functions when a person's organs are unable to perform adequately on their own. This may include mechanical ventilators that support breathing, dialysis machines that assist kidney function, or other technologies that monitor and maintain critical bodily processes. Life support systems are crucial in emergencies or severe medical conditions where organ failure occurs. In contrast, a lift/draw sheet is a tool used for safely moving or repositioning patients rather than supporting life-sustaining functions. A living will is a legal document that outlines a person's preferences for medical treatment in situations where they may be unable to communicate their wishes, but it does not refer to any specific device or system. A log roll is a technique used to turn a patient while maintaining spinal alignment, often used in situations involving a back injury, rather than referring to a life-sustaining intervention. Understanding the distinct roles and definitions of these terms is important in the medical field, particularly in nursing assistance.
