A nurse is preparing to administer lactated Ringer's 1,500 mL IV over 8 hr to a pregnant client who has gastroenteritis. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["188"]
Infusion rate = Volume / Time Therefore;
Infusion rate= 1,500 mL / 8 hr
Infusion rate = 187.5 mL/hr
Rounded off to the nearest whole number; 188ml/hr

Correct Answer is ["2.9"]
Explanation
Let’s calculate the IV pump rate for administering dobutamine to a preterm newborn.
Step 1 is to convert the dose from mcg/kg/min to mg/kg/min. We know that 1 mg = 1000 mcg, so we have:
12 mcg/kg/min ÷ 1000 = 0.012 mg/kg/min
Step 2 is to calculate the total amount of dobutamine the newborn needs per minute:
0.012 mg/kg/min × 2 kg = 0.024 mg/min
Step 3 is to convert this to an hourly rate:
0.024 mg/min × 60 min/hr = 1.44 mg/hr
Step 4 is to calculate the volume of the solution that contains this amount of dobutamine. We know that 250 mg of dobutamine is dissolved in 500 mL of solution, so:
(1.44 mg/hr ÷ 250 mg) × 500 mL = 2.88 mL/hr
So, the nurse should set the IV pump to deliver approximately 2.9 mL/hr (rounded to the nearest tenth).
Correct Answer is ["10"]
Explanation
IV pump rate (mL/hr) = (units/hr x volume) / total units
In this case, the units/hr is 1,000, the volume is 250 mL, and the total units is 25,000. IV pump rate (mL/hr) = (1,000 x 250) / 250,000
Therefore;
IV pump rate (mL/hr) = 250,000 / 25,000 IV pump rate (mL/hr) = 10
Therefore, the nurse should set the IV pump to deliver 10 mL/hr.
