Correct Answer is ["125"]
Explanation
Step 1: Determine the total time required to infuse 40 mEq at a rate of 10 mEq/hr.
40 mEq ÷ 10 mEq/hr = 4 hours
Result: 4 hours
Step 2: Determine the infusion rate in mL/hr.
500 mL ÷ 4 hours = 125 mL/hr
Result: 125 mL/hr
The nurse should set the IV pump to deliver 125 mL/hr.
Correct Answer is C
Explanation
Choice A Reason: This is incorrect because hypervolemia is a condition of excess fluid volume in the body. A client who has an extensive burn injury is more likely to have hypovolemia, which is a condition of low fluid volume, due to fluid loss from the damaged skin and capillaries.
Choice B Reason: This is incorrect because metabolic alkalosis is a condition of high blood pH and high bicarbonate level. A client who has an extensive burn injury is more likely to have metabolic acidosis, which is a condition of low blood pH and low bicarbonate level, due to increased production of lactic acid and ketones from tissue hypoxia and breakdown.
Choice C Reason: This is correct because low hemoglobin is a common laboratory finding in a client who has an extensive burn injury. Hemoglobin is the protein in red blood cells that carries oxygen. A client who has an extensive burn injury may have low hemoglobin due to hemolysis, which is the destruction of red blood cells, or hemorrhage, which is the loss of blood.
Choice D Reason: This is incorrect because hyperkalemia is a condition of high blood potassium level. A client who has an extensive burn injury may have hyperkalemia in the early phase of injury, due to cell damage and potassium release, but it is usually transient and followed by hypokalemia, which is a condition of low blood potassium level, due to fluid loss and potassium depletion.
