A nurse is preparing to administer heparin 3800 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 whole hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.76"]
Formula:
Volume to Administer (mL) = Desired Dose (units) / Available Concentration (units/mL)
Desired Dose: 3800 units
Available Concentration: 5000 units/mL
Volume to Administer(mL) = 3800 units / 5000 units/mL
= 0.76 mL

Correct Answer is ["32"]
Explanation
Formula:
Volume (mL/hr) = (Desired Units/hr × Total Volume (mL)) / Available Units
Desired Units/hr: 1600 units/hr
Total Volume (mL): 500 mL
Available Units: 25,000 units
Volume(mL/hr) = (1600 units/hr × 500 mL) / 25,000 units
= 32 mL/hr
Correct Answer is ["0.5"]
Explanation
Convert mcg to mg:
Convert mcg to mg: 1mg = 1000mcg
125 mcg / 1000 mcg/mg
= 0.125 mg
Calculate the number of tablets:
Number of tablets = Desired dose (mg) / Available tablet strength (mg)
=0.125 mg / 0.25 mg/tablet
= 0.5 tablet
