Certified Rehabilitation Registered Nurse (CRRN) Practice Exam

Which assessment tool is frequently used to evaluate a patient's functional abilities?

1. Barthel index

2. Mini-Mental State Examination

3. Glasgow Coma Scale

4. Pain assessment scale

The correct answer is: Barthel index

The Barthel index is a widely recognized assessment tool used to evaluate a patient's functional abilities, particularly in performing daily living activities. This tool assesses various tasks related to self-care, mobility, and overall independence. By measuring how well a person can perform activities such as feeding, bathing, grooming, dressing, bowel control, bladder control, and mobility, the Barthel index provides valuable insights into the patient's level of functioning and the extent of assistance they may require. The Barthel index is particularly useful in rehabilitation settings and for monitoring changes over time, making it essential for healthcare professionals to understand a patient’s progress and adjust treatments accordingly. In contrast, the Mini-Mental State Examination is designed to assess cognitive function rather than functional abilities, the Glasgow Coma Scale focuses specifically on a patient's level of consciousness and neurological status, and pain assessment scales are utilized to measure the intensity of pain rather than functional status. Thus, the Barthel index stands out for its direct focus on assessing daily living capabilities.
