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.).

Answer and Explanation

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 A

Explanation

“Patient’s platelets 100,000.” A nurse should report a low platelet count to the provider because it may indicate heparin-induced thrombocytopenia (HIT), a serious complication of heparin therapy.
Choice B is not correct because a Prothrombin time (PT) of 12 seconds is within the normal range and does not need to be reported.
Choice C is not correct because Thrombin time (TT) is not typically used to monitor heparin therapy.
Choice D is not correct because a Hematocrit of 35% is within the normal range and does not need to be reported.

A. 20 gtt/min. B. 30 gtt/min. C. 120 gtt/min. D. 50 gtt/min.

Correct Answer is C

Explanation

The nurse should set the flow rate to deliver 40 gtts/min.
This can be calculated by multiplying the infusion rate (120 mL/hr) by the drop factor (60 gtt/mL) and then dividing by the number of minutes in an hour (60 min/hr): (120 mL/hr) * (60 gtt/mL) / (60 min/hr) = 120 gtt/min
Choice A is not the best answer because setting the flow rate to deliver 20 gtts/min would not provide the desired infusion rate of 120 mL/hr.
Choice B is not the best answer because setting the flow rate to deliver 30 gtts/min would not provide the desired infusion rate of 120 mL/hr.
Choice D is not the best answer because setting the flow rate to deliver 50 gtts/min would provide a higher infusion rate than desired.
