Registered Practical Nurse (RPN) Practice Test

What neurobiologic change has been identified as a potential cause of somatoform disorder?

1. Hypersensitivity in brain chemistry.

2. Hyperactivity in neurotransmitter production.

3. Hypometabolism.

4. Increased cortisol levels.

The correct answer is: Hypometabolism.

The identification of hypometabolism as a potential cause of somatoform disorder emphasizes the complex relationship between brain function and psychological symptoms. Hypometabolism refers to reduced metabolic activity in certain areas of the brain, which may influence how individuals process sensory information and perceive bodily sensations. In the context of somatoform disorders, where physical symptoms manifest without a clear physiological explanation, this change may contribute to an altered emotional and somatic experience. Patients may have difficulty interpreting normal bodily sensations, which can lead to an exaggerated focus on these sensations and result in the presentation of physical complaints. Understanding the neurobiological underpinnings such as hypometabolism helps to illuminate the mechanisms behind somatoform disorders and supports the notion that these conditions are not merely psychological but may involve genuine neurobiological changes that affect perception and emotional regulation. This information is crucial for nursing practice, as it assists in holistic patient assessment and management strategies that address both psychological and physical dimensions of care.
