Cognitive Reflection Test (CRT) Practice

Which factor is a common cause of delirium?

1. High physical activity

2. Controlled diet

3. Fluid and electrolyte imbalances

4. Regular sleep patterns

The correct answer is: Fluid and electrolyte imbalances

Fluid and electrolyte imbalances are indeed a common cause of delirium. Delirium, which is an acute state of confusion, can be triggered by various physiological changes in the body. When there are imbalances in fluids and electrolytes, it can significantly affect brain function. This can occur due to dehydration, certain medications, or underlying health conditions that disturb normal bodily functions. The brain is particularly sensitive to these imbalances, which can lead to symptoms such as confusion, disorientation, and changes in attention or perception. In contrast, high physical activity, a controlled diet, and regular sleep patterns are generally beneficial for maintaining cognitive function and overall health. While disturbances in these areas can contribute to health issues, they are not direct causes of delirium as fluid and electrolyte imbalances are.
