Certified Rehabilitation Registered Nurse (CRRN) Practice Exam

Which assessment result may indicate delayed capillary refill?

1. Color return within 5 seconds

2. Color return within 3 seconds

3. Color return within 2 seconds

4. Color clear immediately

The correct answer is: Color return within 5 seconds

Delayed capillary refill time is an important assessment parameter, especially in evaluating peripheral circulation and overall perfusion status. Typically, capillary refill should occur in less than 2 seconds in healthy individuals. When return of color to the nail bed or skin takes longer than this, it indicates reduced blood flow, which could be due to a variety of factors such as shock, dehydration, or circulatory issues. The correct answer reflects a circumstance where color returns within 5 seconds. This time frame exceeds the normal threshold for capillary refill. A return of color in this duration suggests a delay in circulation, which may require further investigation and potentially immediate intervention. The importance of this assessment lies in its ability to signal to healthcare providers that there may be underlying issues affecting a patient’s circulatory system.
