Certified Healthcare Constructor (CHC) Practice Exam

What are the three requirements for tubing used in positive pressure medical gas systems delivered from the manufacturer?

1. Plugged or capped, Hard-drawn seamless, Identified as "oxy" or "med"

2. Flexible and color-coded, Made from plastic, Marked with manufacturer label

3. Resistant to high pressure, Low thermal conductivity, Easy to install

4. Corrosion-resistant, Light-weight, Reusable

The correct answer is: Plugged or capped, Hard-drawn seamless, Identified as "oxy" or "med"

The correct choice identifies essential characteristics that safety and regulatory standards require for tubing used in positive pressure medical gas systems. The need for the tubing to be plugged or capped ensures that it remains sterile and uncontaminated prior to installation. This is critical in medical settings where the risk of infection must be minimized. Hard-drawn seamless construction prevents leaks and failures under pressure, providing a reliable pathway for delivering medical gases. Additionally, being specifically identified as "oxy" or "med" helps prevent any confusion with other types of gases or tubing, ensuring that only the correct gases are used in medical applications. These distinctions are crucial for maintaining patient safety and compliance with standards governing medical equipment. In contrast, the other choices focus on features that are not mandated or may not be suitable for medical gas delivery. The alternative options include attributes that may not address the specific safety, material integrity, and identification requirements necessary for effective use in a healthcare environment.
