A nurse is caring for a client who has a deep vein thrombosis and is prescribed heparin by continuous IV infusion at 1,200 units/hr. Available is heparin 25,000 units in 500 mL DSW. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["24"]
To calculate the infusion rate, use the formula:
(rate in mL/hr) = (desired dose in units/hr) / (available dose in units/mL)
In this case, the desired dose is 1,200 units/hr and the available dose is 25,000 units / 500 mL = 50 units/mL. Therefore,
(rate in mL/hr) = (1,200 units/hr) / (50 units/mL) = 24 mL/hr
Round the answer to the nearest tenth/whole number and use a leading zero if it applies. Do not use a trailing zero because it could be misread as a decimal point. Therefore, the nurse should set the IV pump to deliver 24 mL/hr.

Correct Answer is ["1"]
Explanation
To calculate the number of tablets, divide the total dose by the dose per tablet. In this case, the total dose is 1.5 mg / 3 = 0.5 mg and the dose per tablet is 0.5 mg. Therefore,
(number of tablets) = (0.5 mg) / (0.5 mg) = 1 tablet
Round the answer to the nearest tenth and use a leading zero if it applies. Do not use a trailing zero because it could be misread as a decimal point. Therefore, the nurse should administer 1 tablet per dose.
