Certified Transport Registered Nurse Certification Practice Exam

Which condition is NOT a physiological effect of noise during transport?

1. Increased heart rate

2. Decreased attention

3. Improved digestion

4. Increased irritability

The correct answer is: Improved digestion

The chosen answer highlights an important aspect of how noise influences physiological responses. Increased heart rate, decreased attention, and increased irritability are all common physiological effects associated with exposure to noise. These effects occur because noise can trigger the body's stress response, leading to increased sympathetic nervous system activity, which raises heart rate and can impair focus due to distractions. Additionally, constant exposure to loud sounds can contribute to feelings of irritability and stress. In contrast, improved digestion does not align with the typical physiological effects of noise. In fact, high levels of noise can disrupt the digestive process, as stress and distraction can lead to reduced gastrointestinal motility and other complications. Therefore, identifying improved digestion as a non-physiological effect of noise during transport is consistent with understanding the overall impact of noise on human functioning.
