The nurse would explain to a client that when a major burn occurs, the body's initial systemic responses include
a. elevated pulse rate, decreased cardiac output, and polyuria.
b. increased capillary permeability, decreased cardiac output, and oliguria.
c. plasma leakage into surrounding tissue, decreased hematocrit, and oliguria.
d. production of epinephrine, vasodilation, and increased cardiac output.
B
Immediately following a burn injury, vasoactive substances are released from the injured tissues. These substances initiate changes in capillary integrity, allowing plasma to seep into surrounding tissues. Direct heat injury to vessels further increases capillary permeability, which permits sodium ions to enter the cell and potassium ions to exit. Overall, this creates an osmotic gradient, which leads to increases in intracellular and interstitial fluid volumes and further depletion of intravascular fluid volume.
