Answer: B) apply gentle traction to the bone injury and splint the ankle with a padded rigid splint.
Step-by-step explanation:
Capillary refill time is the time taken by the capillary bed to change color from red to complete blanching. It can be measured by holding the hand to a level higher than the heart level and by applying pressure over the soft pad of fingers and observing the color change. Normal capillary refill time is 2 seconds.
A capillary time of 4 seconds indicates that capillaries are not functioning properly and blood is not reached immediately over the feet. Thus application of traction can help by pulling the fractured body part. The split is a medical device which can provide support to the ankle.
