Your patient is receiving Heparin via a continuous IV infusion at a rate of 1600 units per hour.
The bag is labeled N/S 500 mLs and contains Heparin 40,000 units.
What rate should the IV pump be set at to deliver this ordered amount of Heparin? mLs/hr.
The Correct Answer is ["mLs\/hr."]
Answer and explanation
Step 1 is to calculate the total units of Heparin in 1 mL of the solution. This is done by dividing the total units of Heparin in the bag (40,000 units) by the total volume of the bag (500 mL). So, 40,000 units ÷ 500 mL = 80 units/mL. Step 2 is to calculate the rate at which the IV pump should be set. This is done by dividing the ordered amount of Heparin per hour (1600 units) by the units of Heparin per mL (80 units/mL). So, 1600 units/hr ÷ 80 units/mL = 20 mL/hr.
So, the correct answer is 20 mL/hr.

Correct Answer is C
Explanation
Choice A rationale:
The back of the hand is sensitive to temperature, not pressure, making it less suitable for assessing contraction intensity.
Choice B rationale:
Finger tips are sensitive and can detect small changes, but they may not cover a large enough area to accurately assess contraction intensity.
Choice C rationale:
The palm of the hand covers a larger area and can better gauge the overall firmness of the uterus.
Choice D rationale:
Finger pads are sensitive to texture, not pressure, making them less suitable for this task.
