Your patient has recently suffered from a stroke and has been prescribed heparin in accordance with your unit’s heparin dosing protocol. This protocol uses the nomogram below. The goal of this therapy is to maintain aPTT value between 55 and 69.9 sec.

aPTT (sec)	Rate Change (mL/hr)
< 35	↑ by 3 mL/hr
35 – 44.9	↑ by 2 mL/hr
45 – 54.9	↑ by 1 mL/hr
55 – 69.9	no change
70 – 84.9	↓ by 1 mL/hr
85 – 100	stop infusion for 30 min; ↓ by 2 mL/hr
> 100	stop infusion for 60 min; ↓ by 4 mL/hr

You are currently delivering the heparin solution at 13 mL/hr. You have just received a lab report indicating an aPTT value of 73.8 sec. What is the new flow rate for this patient? Indicate the quantity and unit of measure where specified.
