Normal capillary refill time is

• A. 1 second
• B. 3 seconds
• C. 2 seconds or less
• D. 5 seconds

Answer: (C)

Capillary refill time gauges peripheral perfusion by observing how quickly color returns to a pressed nail bed after blanching. When you press firmly on a nail bed until it blanches and then release, the color should return within 2 seconds or less. A refill over 2 seconds can indicate reduced peripheral perfusion from dehydration, shock, or vasoconstriction, though results can be influenced by temperature, ambient conditions, age, and technique. This quick bedside check is used alongside other assessments to gauge circulatory status.
