A nurse is preparing to administer heparin 2.000 units by IV bolus. Available is heparin injection 5.000 units/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.4"]
Step-by-Step Calculation
Understanding the Problem
We need to administer 2000 units of heparin.
The available concentration of heparin is 5000 units/mL.
We need to find the volume to administer.
Calculations
Set up a proportion:
5000 units / 1 mL = 2000 units / x mL
Cross-multiply:
5000x = 2000
Solve for x:
x = 2000 / 5000
x = 0.4 mL
The nurse should administer 0.4 mL of heparin.

Correct Answer is ["200"]
Explanation
The nurse is administering 1 g of ceftriaxone sodium in 100 mL of dextrose 5% in water over 30 minutes.
To find out how many mL/hr the IV pump should be set to, we can divide the total volume by the total time.
Infusion time in hours = 30 minutes / 60 minutes/hour = 0.5 hours
Infusion rate (mL/hr) = 100 mL / 0.5 hours = 200 mL/hr
