A nurse prepares to administer 0.9% sodium chloride 200 mL over 30 min. The nurse should set the IV infusion pump to administer 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 ["400"]
Infusion rate (mL/hr) = 200 mL / 0.5 hr Infusion rate (mL/hr) = (200 mL/hr) *2
= 400mls/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 ["2500"]
Explanation
Step 1: Convert liters to milliliters.
1 liter is equal to 1000 milliliters. Therefore, we can convert 2.5 liters to milliliters as follows:
2.5 liters * 1000 milliliters/liter = 2500 milliliters
Step 2: Round the answer to the nearest whole number.
The answer is 2500 milliliters. Since we are instructed to round to the nearest whole number, we do not need to make any changes.
Therefore, the nurse should administer 2500 mL of lactated Ringer's to the client.
