Certified Transport Registered Nurse Certification Practice Exam

What is barobariatrauma primarily associated with in terms of body changes?

1. Fluid retention in tissues

2. Gas expansion and nitrogen accumulation

3. Muscle fatigue due to lack of oxygen

4. Bone density reduction

The correct answer is: Gas expansion and nitrogen accumulation

Barobariatrauma is primarily associated with gas expansion and nitrogen accumulation as it occurs during rapid changes in atmospheric pressure, commonly experienced in scuba diving or high-altitude flying. When the pressure decreases, gases that are dissolved in body fluids, particularly nitrogen, come out of solution and can lead to formation of bubbles. This process is primarily a result of Boyle’s Law, where a gas expands as pressure decreases, leading to potential injury or trauma. This condition is also closely linked to decompression sickness, which can result in significant physiological effects, including pain and damage to various tissues and organs. Understanding this concept is critical for transport nurses, especially when managing patients who have been involved in activities that involve significant pressure changes.
