Certified Transport Registered Nurse Certification Practice Exam

What elevation marks the disturbance stage for altitude effects?

1. 15,000 - 20,000 ft

2. 20,000 - 25,000 ft

3. 10,000 - 15,000 ft

4. 5,000 - 10,000 ft

The correct answer is: 15,000 - 20,000 ft

The correct answer regarding the elevation that marks the disturbance stage for altitude effects is indeed between 15,000 and 20,000 feet. At this altitude range, individuals can begin to experience significant physiological changes due to decreased atmospheric pressure and lower oxygen availability. In this disturbance stage, many climbers and travelers may experience symptoms of acute mountain sickness, which can include headaches, dizziness, and nausea. The body is still adapting to the thinner air, but the effects become more pronounced within this altitude range, leading to what is typically described as mild to moderate altitude sickness. Understanding this concept is crucial for transport nurses or healthcare professionals involved in the care of patients at higher altitudes, as it helps inform risk assessment and necessary interventions for patients who may experience altitude-related conditions. Proper education on acclimatization and recognition of the early symptoms of altitude sickness is essential for patient safety and health management in these elevation thresholds.
