During your assessment of a 6-month-old male with vomiting and diarrhea, you note that his capillary refill time is approximately 4 seconds. From this information, you should conclude that the infant's:

peripheral circulation is decreased

Explanation:

Systemic circulation, also called large circulation, transports blood to all tissues of the body. In addition, it also ensures the nutrition of the vessels that constitute the small circulation, or pulmonary circulation. It is called large circulation or peripheral circulation. When this circulation is slowed there is a delay in the time to recharge hair, which must occur simultaneously.

The infant in question is experiencing a delay in capillary recharge time, so we can conclude that the baby's peripheral circulation is decreased
