A client with third- and fourth-degree burns is in the burn unit. The nurse understands that which of the following is true regarding fluid shift in burn clients?
The fluid shift can cause hypokalemia and hypovolemia.
Hemoconcentration increases blood flow and reduces blood viscosity.
Excessive weight loss can occur during the first 12 hours post burn due to the fluid shift.
Severe edema can occur in areas that were not burned, due to the leakage of electrolytes and fluids from the vascular space.
Number 4 is correct.
Rationale: Severe edema can occur in areas that were not burned, due to the leakage of electrolytes and fluids from the vascular space. The fluid shift causes hyperkalemia and hypovolemia. Hemoconcentration is caused by vascular dehydration, which increases blood viscosity. Excessive weight gain can occur during the first 12 hours following the burn and may continue for 24 – 36 hours due to the fluid shift.
