A nurse is preparing to administer 400 mL of 0.9% sodium chloride IV over 8 hours.
The drop factor of the manual IV tubing is 60 gtt/mL.
The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number.
Use a leading zero if it applies. Do not use a trailing zero.).
The Correct Answer is ["50"]
To calculate the flow rate in gtt/min, you need to divide the total volume of the IV fluid (400 mL) by the total infusion time in minutes (8 hours x 60 minutes/hour = 480 minutes) and then multiply by the drop factor of the manual IV tubing (60 gtt/mL).
This gives you a flow rate of (400 mL / 480 minutes) x 60 gtt/mL = 50 gtt/min.
The other choices are not answers because they are not provided in the question.

Correct Answer is D
Explanation
Heparin is an anticoagulant that is used to decrease the clotting ability of the blood and help prevent harmful clots from forming in blood vessels 1.
However, heparin will not dissolve blood clots that have already formed, but it may prevent the clots from becoming larger and causing more serious problems 12.
Choices A, B, and C are incorrect because heparin does not dissolve existing clots. Instead, it works to prevent new clots from forming 12.
Correct Answer is B
Explanation
Step 1: Calculate the total infusion time in minutes.
24 hours × (60 minutes/hour) = 1440 minutes.
Step 2: Calculate the infusion rate in mL/min.
1200 mL ÷ 1440 minutes = 0.833 mL/min.
Step 3: Calculate the drop rate in gtt/min.
0.833 mL/min × 15 gtt/mL = 12.495 gtt/min.
Step 4: Round to the nearest whole number.
12.495 ≈ 13 gtt/min.
Answer: 13 gtt/min.
