A nurse is monitoring a client who was admited with a severe burn injury and is receiving IV ﬂuid resuscitation therapy. The nurse should identify a decrease in which of the following findings as an indication of adequate ﬂuid replacement?

Urine output

Heart rate

Weight

Blood pressure

Answer and Explanation

The Correct Answer is B

Choice A Reason: Urine output is not a finding that should decrease with adequate ﬂuid replacement. On the contrary, urine output should increase as the ﬂuid therapy restores the renal perfusion and function. The nurse should monitor the urine output and ensure that it is at least 0.5 mL/kg/hr for adults and 1 mL/kg/hr for children.

Choice B Reason: Heart rate is a finding that should decrease with adequate ﬂuid replacement. A high heart rate is a sign of hypovolemia, which occurs when the burn injury causes ﬂuid loss from the intravascular space. The nurse should monitor the heart rate and expect it to decrease as the ﬂuid therapy replenishes the blood volume and improves the cardiac output.

Choice C Reason: Weight is not a finding that should decrease with adequate ﬂuid replacement. On the contrary, weight may increase as the ﬂuid therapy restores the hydration status and corrects the ﬂuid deficit. The nurse should monitor the weight and compare it with the pre-burn weight to evaluate the ﬂuid balance.

Choice D Reason: Blood pressure is not a finding that should decrease with adequate ﬂuid replacement. On the contrary, blood pressure may increase as the ﬂuid therapy restores the vascular tone and improves the tissue perfusion. The nurse should monitor the blood pressure and expect it to increase as the ﬂuid therapy compensates for the ﬂuid loss.

Correct Answer is ["24"]

Explanation

To find the concentration of heparin in the solution, divide the amount of heparin by the volume of D5W: 25,000 units / 500 mL = 50 units/mL
To find the infusion rate, divide the prescribed dose by the concentration: 1,200 units/hr / 50 units/mL = 24 mL/hr
Round the answer to the nearest tenth/whole number: 24 mL/hr

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.
