At 1400, there is 240.mL TBA.

b) Is the IV on time, ahead or behind, and by how much (mL)? / 4

c) What is the new flow rate (mL/hr)? / 4

d) What is the new drip rate (gtt/min)? / 3

2. You arrive for your 1600 – midnight shift, and Mr. Yazdanian is undergoing IV therapy using RL w/ 20.mEq.KCl/L @.70.mL/hr. When you arrive at 1600, there is 625.mL remaining in the IV bag. The IV drop factor is 30.gtt/mL.
