A nurse is preparing to administer furosemide 40 mg via IV bolus to a client. The amount available is furosemide 10 mg/1 mL. How many mL should the nurse administer per dose? (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 ["4"]
Desired dose = 40 mg
Available concentration = 10 mg/mL
To calculate the volume to administer:
Volume (mL) = Desired dose (mg) / Concentration (mg/mL)
Volume = 40 mg / 10 mg/mL = 4 mL

Correct Answer is ["200"]
Explanation
Understanding the Problem
We need to administer 100 mL of solution over 30 minutes.
We need to convert the rate to mL/hour.
Calculations
Convert minutes to hours:
30 minutes = 30/60 hours = 0.5 hours
Calculate the infusion rate:
Infusion rate (mL/hr) = Total volume (mL) / Time (hr)
Infusion rate = 100 mL / 0.5 hr = 200 mL/hr
Answer
The nurse should set the IV pump to deliver 200 mL/hr.
Correct Answer is ["24"]
Explanation
We need to deliver 1200 units of heparin per hour.
The bag contains 25,000 units of heparin in 500 mL of D5W.
To find the mL/hr needed to deliver 1200 units/hr, we can use the following formula:
(Desired dose in units/hr) / (Concentration of heparin in units/mL) = mL/hr
First, we need to find the concentration of heparin in the solution:
25,000 units / 500 mL = 50 units/mL
Now, we can calculate the infusion rate:
1200 units/hr / 50 units/mL = 24 mL/hr
