A nurse is caring for a client with a pulmonary embolism who weighs . The client is receiving a continuous intravenous heparin infusion. The current infusion rate is . The heparin is supplied as in of 5% dextrose in water.
The client's morning activated partial thromboplastin time (aPTT) is . According to the hospital's weight-based heparin protocol, for an aPTT between and , the nurse must administer an intravenous bolus of and increase the continuous infusion rate by .
Calculate the client's new continuous infusion pump rate in . (Record your answer using one decimal place.)
Cevap: 13.7 mL/hr
Cevap
13.7
To safely titrate a heparin infusion based on a protocol, the nurse must first determine the new dose by adding the prescribed increase to the current rate (14 + 2 = 16 units/kg/hr). Next, calculate the total hourly dose using the client's weight (16 units/kg/hr * 85.4 kg = 1366.4 units/hr). The concentration of the IV bag is 100 units/mL (25,000 units / 250 mL). Finally, divide the total hourly units by the concentration to find the pump rate in mL/hr (1366.4 / 100 = 13.664), which rounds to 13.7 mL/hr.
