A nurse is caring for a client is 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 D5W. 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"]
- First, determine the concentration of the heparin solution. In this case, it's 25,000 units in 500 mL, which means there are 50 units per mL.
- Next, calculate the required rate to deliver 1,200 units per hour. Since the concentration is 50 units per mL, divide 1,200 units by 50 units/mL to find the required mL per hour.
- The calculation will be 1,200 units/hr ÷ 50 units/mL = 24 mL/hr.
- Since the question asks to round to the nearest tenth or whole number, and the result is a whole number, the IV pump should be set to deliver 24.0 mL/hr.

Correct Answer is B
Explanation
A. Obtain a cardiology consult is not an immediate action for an irregular heart rate during suctioning; it is a more long-term consideration.
B. Perform pre-oxygenation prior to suctioning is the correct action to prevent hypoxia, which can cause increased heart rate and irregular rhythms during suctioning.
C. Administer an antidysrhythmic medication is not appropriate for the immediate concern of heart rate changes during suctioning.
D. Suction the client less frequently does not address the acute problem of the irregular heart rate; pre-oxygenation before suctioning is more relevant.
