Question

A client weighing $198\text{ lb}$ is receiving a continuous intravenous (IV) heparin infusion for the treatment of a deep vein thrombosis. The client's morning activated partial thromboplastin time (aPTT) is reported as $42\text{ seconds}$. According to the facility's weight-based heparin protocol, for this aPTT result, the nurse must administer an IV push bolus of $40\text{ units/kg}$ and increase the continuous infusion rate by $2\text{ units/kg/hr}$. The continuous IV infusion is currently running at $14\text{ units/kg/hr}$. The pharmacy provides a premixed heparin bag containing $25,000\text{ units}$ in $250\text{ mL}$ of $0.9\%$ sodium chloride, and a separate heparin vial containing $1,000\text{ units/mL}$ for the bolus dose.

After administering the required bolus, at what rate in $\text{mL/hr}$ should the nurse set the IV pump for the new continuous infusion? (Record your answer to the nearest tenth.)
