Final answer:
The nurse can assess a child's capillary refill time by observing the child's skin color return after blanching.
Step-by-step explanation:
The nurse can assess a child's capillary refill time by observing the child's skin color return after blanching.
Capillary refill time is the amount of time it takes for blood to return to the capillaries after they have been compressed. By pressing on the child's skin and then releasing the pressure, the nurse can see how quickly the skin color returns to normal.
For example, if the child's skin color returns to normal within 2 seconds, it indicates a normal capillary refill time.
