Which process would be expected in the first 24 hours following a serious burn?

a. Increased capillary permeability
b. Diuresis
c. Decreased levels of stress hormones
d. Fluid overload

Question 2

Hypovolemia in the early stages of burn shock is directly related to:

a. decreased cardiac contractility and shunt-ing of blood away from visceral organs.
b. increased capillary permeability and evap-orative water loss.
c. hypometabolism and renal water loss.
d. bacterial infection of the wound and re-sulting bacteremia.

Answer to Question 1

ANS: A
Increased capillary permeability occurs, leading fluid to shift to interstitial spaces. Blood is shunted from the kidneys, so decreased urination occurs. Increased levels of stress hormones are secreted. Hypovolemia, not fluid overload, occurs.

Answer to Question 2

ANS: B
Hypovolemia occurs due to increased capillary permeability. Decreased cardiac contractility oc-curs, but this is not the direct cause of hypovolemia. Blood is shunted from the kidneys, so water loss does not occur. Bacterial infection is a risk, but it is not the cause of hypovolemia.
