Simulated
A nurse is preparing to infuse 1400 units/hr of heparin sodium for a client with pulmonary embolism (PE). The amount available is 25,000 units in a 250 mL bag of 0.9 sodium chloride. How will the nurse set up the flow rate (mL/hr)? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct answer
14
Rationale
Rationale for Correct Answer (14 mL/hr): To calculate the flow rate for heparin infusion, use the formula: (Total units to infuse ├À units in bag) x mL in bag x (60 ├À infusion time in minutes). In this case, it would be: (1400 ├À 25000) x 250 x (60 ├À 60) = 14 mL/hr. This ensures the correct dose is delivered over the specified time frame.
Summary of Incorrect Choices:
- Other choices would result from miscalculating the flow rate formula, leading to incorrect infusion rates.
- Incorrect choices may stem from errors in unit conversions or not considering the total units and volume available in the bag.
- Choosing any other options would result in an inaccurate flow rate, potentially compromising the effectiveness of the heparin infusion for the client with PE.
