Solved in 4 steps
- Hi , Could you pls help this math ....pls include your calculate step/ fomulation before your answer. If your answer different from us, we know why you got that answer. Thanks 1. 100ml of IV is ordered over 6 hours. The drop factor is 20. The IV has been running for 4 hours and 400 mls remain in the bag. How many drops/per minutes are required thus the IV infusion completes at the needed time? 2. One IV back containing 400 mg of medication in 100 mls is to be infused to Jack over 120mins. What rate should you set the IV pump at? 3. One IV back have 130 mg of drug in 250 mls is to be infused over half hour. What rate should you set the IV pump at? 4. 1000 ml IV is ordered over 240 mins. The drop factor is 30. The IV has been running for 120mins and still 600mls remain in the flask. How many drops/per minute are required so that the IV finishes at the needed time?Project Controlling Red Blood Cell Loss During Surgery A typical volume of blood in the human body is about 5 L. A certain percentage of that volume (called the hematocrit) consists of red blood cells (RBCs); typically the hematocrit is about 45% in males. Suppose that a surgery takes four hours and a male patient bleeds 2 L of blood. During surgery the patient's blood volume is maintained at 5 L by injection of saline solution, which mixes quickly with the blood but dilutes it so that the hematocrit decreases as time passes. 1. Assuming that the rate of RBC loss is proportional to the concentration of RBCs, determine the patient's concentration of RBCs by the end of the operation. 2. A procedure called acute normovolemic hemodilution (ANH) has been developed to minimize RBC loss during surgery. In this procedure blood is extracted from the patient before the operation and replaced with saline solution. This dilutes the patient's blood, resulting in fewer RBCs being lost during the…
