A nurse is preparing to administer 0.9% sodium chloride 200 mL IV to infuse over 24 hr. The drop factor of the manual IV tubing is 15 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 ["13"]

Calculations

Calculate the total minutes:

24 hours = 24 X 60 minutes = 1440 minutes

Calculate the infusion rate in mL/min:

Infusion rate (mL/min) = Total volume (mL) / Total time (min)

Infusion rate = 1200 mL / 1440 min = 0.8333 mL/min

Calculate the drip rate:

Drip rate (gtt/min) = Infusion rate (mL/min) X Drop factor (gtt/mL)

Drip rate = 0.8333 mL/min X 15 gtt/mL = 12.5 gtt/min

The nurse should set the manual IV infusion to deliver 13 gtt/min.

Correct Answer is B

Explanation

A) 1600: If the nurse were to administer the next bag at 1600, it would imply that the current solution would need to last only 2 more hours. However, with 500 mL remaining and a total infusion time of 8 hours, this timing would not align with the need to complete the full infusion period appropriately.

B) 1800: Since the IV solution is meant to be infused over 8 hours and 500 mL (half of the total 1,000 mL) has been infused by 1400, the remaining 500 mL should also be infused over the next 4 hours. Infusing the next bag at 1800 would ensure that the entire 8-hour infusion time is met correctly.

C) 1700: Administering the next bag at 1700 would mean that there would be only 3 hours left to infuse the remaining solution. This timing would not allow for a complete 8-hour infusion period as required.

D) 1500: If the nurse were to administer the next bag at 1500, it would be too early, as only 2 hours would have passed since starting the current bag. This would not be appropriate given the need to infuse the solution over the full 8-hour period.

A. 32 units B. 28 units C. 14 units D. 42 units

Correct Answer is D

Explanation

A) 32 units: This calculation only includes the 14 units of regular insulin and a portion of the NPH insulin. The total units of insulin required are not 32 but rather the sum of both regular and NPH insulins.

B) 28 units: This amount represents only the units of NPH insulin and does not include the regular insulin, which is also prescribed.

C) 14 units: This amount represents only the units of regular insulin and does not include the NPH insulin, which is also prescribed.

D) 42 units: The total number of insulin units required is the sum of the regular insulin (14 units) and the NPH insulin (28 units), which equals 42 units. This total should be prepared in the insulin syringe to ensure the correct dosage is administered.
