Certified Transport Registered Nurse Certification Practice Exam

What is the decibel level associated with fixed-wing transport?

1. 120 - 140 dB

2. 130 - 150 dB

3. 140 - 160 dB

4. 150 - 170 dB

The correct answer is: 140 - 160 dB

Fixed-wing transport, such as medical aircraft, generally produces noise levels within the range of 140 to 160 dB. This elevated decibel level is primarily due to the aircraft's engines and aerodynamic factors during flight. Understanding these noise levels is crucial for transport nurses because excessive noise can impact patient comfort and potentially influence physiological parameters, such as stress response and hemodynamic stability. Being familiar with these ranges helps transport nurses prioritize effective communication and care strategies in the unique environment of air transport.
