A nurse is caring for a client with a pulmonary embolism who requires a continuous IV infusion of heparin. The client's weight is $176\text{ lbs}$ . The healthcare provider prescribes heparin at a rate of $18\text{ units/kg/hr}$ . The available medication is heparin sodium $25,000\text{ units}$ in $250\text{ mL}$ of $0.9\%$ sodium chloride. What rate should the nurse program into the infusion pump in $\text{mL/hr}$ ? Record your answer using one decimal place.

Cevap: 14.4 mL/hr

Cevap

14.4

The correct infusion rate of

14.4\text{ mL/hr}

is achieved by first converting the client's weight to

80\text{ kg}

. Next, the weight is multiplied by the prescribed

18\text{ units/kg/hr}

to find an hourly dose of

1,440\text{ units/hr}

. Finally, since the IV bag concentration is

100\text{ units/mL}

(derived from

25,000\text{ units} / 250\text{ mL}

), dividing the hourly dose by the concentration yields the correct pump setting.

Adım Adım Çözüm

Convert the client's weight from pounds to kilograms.

176\text{ lbs} \div 2.2\text{ lbs/kg} = 80\text{ kg}

The medication is prescribed in units per kilogram, requiring a weight conversion to metric units.

Calculate the hourly dose of heparin in units.

80\text{ kg} \times 18\text{ units/kg/hr} = 1,440\text{ units/hr}

This determines the exact amount of active medication the client needs every hour based on their body weight.

Calculate the infusion pump rate in mL/hr.

1,440\text{ units/hr} \div 100\text{ units/mL} = 14.4\text{ mL/hr}

The concentration is

25,000\text{ units} \div 250\text{ mL} = 100\text{ units/mL}

. Dividing the hourly dose by the concentration provides the volume to be infused per hour.
