In a 2-month-old infant with vomiting and diarrhea, the
most effective way of determining a fluid deficit is to
check for which? Decreased peripheral perfusion
In a 2-month-old infant with vomiting and diarrhea, the
most effective way of determining a fluid deficit is to
check for decreased peripheral perfusion, dry oral
mucous membranes, and sunken fontanels. The body
compensates for loss of fluid by shifting the interstitial

perfusion of vital organs. If the fluid loss continues,
circulating volume is diminished and vasoconstriction
occurs in the peripheral vessels, resulting in decreased
perfusion.
