Physiologically, the child compensates for fluid volume losses by which mechanism?
a. Inhibition of aldosterone secretion
b. Hemoconcentration to reduce cardiac workload
c. Fluid shift from interstitial space to intravascular space
d. Vasodilation of peripheral arterioles to increase perfusion
ANS: C
Compensatory mechanisms attempt to maintain fluid volume. Initially, interstitial fluid moves into the intravascular compartment to maintain blood volume. Aldosterone is released to promote sodium retention and conserve water in the kidneys. Hemoconcentration results from the fluid volume loss. With less circulating volume, tachycardia results. Vasoconstriction of peripheral arterioles occurs to help maintain blood pressure.
