A nurse is preparing to administer lactated Ringer's 1000 ml to infuse over 12 hr. The drop factor on the manual tubing is 10 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.)

Full Explanation
To calculate the infusion rate in drops per minute (gtt/min), we can use the following formula: Infusion rate (gtt/min) = (Volume to be infused (ml) * Drop factor) / Time (min) Given:
Volume to be infused: 1000 ml
Drop factor: 10 gtt/ml
Time: 12 hr
First, we need to convert the time from hours to minutes:
12 hr * 60 min/hr = 720 min
Now, we can calculate the infusion rate:
Infusion rate (gtt/min) = (1000 ml * 10 gtt/ml) / 720 min
Simplifying the equation:
Infusion rate (gtt/min) = 10000 gtt / 720 min
Dividing both sides:
Infusion rate (gtt/min) ≈ 13.89 gtt/min
Rounding the answer to the nearest whole number, the nurse should set the manual IV infusion to deliver approximately 14 gtt/min.

A nurse is preparing to administer dextrose 5% in water (DSW) 1,200 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 to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Full Explanation
To calculate the infusion rate in drops per minute (gtt/min), we can use the following formula: Infusion rate (gtt/min) = (Volume to be infused (ml) * Drop factor) / Time (min) Given:
Volume to be infused: 1,200 ml
Drop factor: 15 gtt/ml
Time: 24 hr
First, we need to convert the time from hours to minutes:
24 hr * 60 min/hr = 1,440 min
Now, we can calculate the infusion rate:
Infusion rate (gtt/min) = (1,200 ml * 15 gtt/ml) / 1,440 min
Simplifying the equation:
Infusion rate (gtt/min) = 18,000 gtt / 1,440 min
Dividing both sides:
Infusion rate (gtt/min) ≈ 12.5 gtt/min
Rounding the answer to the nearest whole number, the nurse should set the manual IV infusion to deliver approximately 13 gtt/min.
A nurse is preparing to administer 0.9% sodium chloride (NS) 100 mL IV to infuse over 4 hr. The drip factor of the manual IV tubing is 60 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min?

Full Explanation
To calculate the infusion rate in drops per minute (gtt/min), we can use the following formula: Infusion rate (gtt/min) = (Volume to be infused (ml) * Drop factor) / Time (min) Given:
Volume to be infused: 100 ml
Drop factor: 60 gtt/ml
Time: 4 hr
First, we need to convert the time from hours to minutes:
4 hr * 60 min/hr = 240 min
Now, we can calculate the infusion rate:
Infusion rate (gtt/min) = (100 ml * 60 gtt/ml) / 240 min
Simplifying the equation:
Infusion rate (gtt/min) = 6000 gtt / 240 min
Dividing both sides:
Infusion rate (gtt/min) ≈ 25 gtt/min
A nurse is preparing to administer dextrose 5% in water IV to infuse at 100 mL/60 min. The drop factor on the manual IV tubing is 60 gtt/ml. The nurse should set the IV flow rate to deliver how many gtt/min? (Round to the nearest whole number.)
Full Explanation
To calculate the IV flow rate in drops per minute (gtt/min), you can use the following formula: Flow rate (gtt/min) = (Volume to be infused in mL) x (Drop factor) / (Time in minutes) In this case, the volume to be infused is 100 mL, the drop factor is 60 gtt/mL, and the time is 60 minutes.
Flow rate (gtt/min) = (100 mL) x (60 gtt/mL) / (60 min)
Canceling out the mL and min units, the formula becomes:
Flow rate (gtt/min) = 100 x 60 / 60
Flow rate (gtt/min) = 100
Therefore, the nurse should set the IV flow rate to deliver 100 gtt/min.
