Oregon Certified Nursing Assistant State Practice Exam

Which of the following statements is true regarding liquid oxygen safety?

1. The NA should not touch liquid oxygen because it can cause frostbite

2. The NA should keep a liquid oxygen tank covered with a thin blanket or sheet

3. The NA should store a liquid oxygen tank on its side

4. The NA should store a liquid oxygen tank in a closet or cupboard

The correct answer is: The NA should not touch liquid oxygen because it can cause frostbite

Touching liquid oxygen can indeed lead to frostbite because it is extremely cold, typically below -200 degrees Fahrenheit. This temperature can cause severe skin damage upon contact, making it crucial for healthcare workers, including nursing assistants, to avoid direct contact with liquid oxygen. This awareness is essential not only for personal safety but also for maintaining a safe environment for patients who may rely on oxygen for respiratory support. In contrast, properly handling and storing liquid oxygen tanks involves specific guidelines that emphasize safety and accessibility. Keeping liquid oxygen equipment covered with thin materials could obstruct airflow or create hazards in a clinical setting. Storing tanks on their side is unsafe because they are designed to be stored upright to prevent potential leaks or ruptures. Additionally, placing oxygen tanks in enclosed spaces such as closets or cupboards poses a risk of gas buildup, which could lead to dangerous situations due to the highly flammable nature of oxygen.
