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

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
Correct Answer is ["31"]
Explanation
Convert hours to minutes: 2 hours X 60 minutes/hour = 120 minutes
Calculate the total number of drops: 250 mL X 15 gtt/mL = 3750 gtt
Calculate the drip rate: 3750 gtt / 120 minutes = 31.25 gtt/min
Round to the nearest whole number: 31 gtt/min
