A nurse preparing to minister 0.9% sodium chloride via continuous IV infusion at 125 mL/hr. The primary tubing has a drop factor of 15gtt/mL. How many gtt/min should the nurse set the infusion pump to administer? (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 ["31"]
Determine the flow rate in mL/min:
The desired flow rate is 125 mL/hr.
There are 60 minutes in an hour.
Flow rate in mL/min: 125 mL/hr ÷ 60 min/hr = 2.0833 mL/min.
Calculate the drip rate in gtt/min:
The drip factor of the tubing is 15 gtt/mL.
This means that for every 1 mL, there are 15 drops.
To find the drip rate in gtt/min:
Drip rate (gtt/min) = Flow rate (mL/min) × Drip factor (gtt/mL)
Drip rate = 2.0833 mL/min × 15 gtt/mL
Calculating the drip rate:
Drip rate = 31.25 gtt/min
Round the answer to the nearest whole number:
Rounding 31.25 to the nearest whole number gives us 31 gtt/min.

Correct Answer is ["12"]
Explanation
Determine the total daily dosage:
The client is prescribed 300 mg of phenytoin every 12 hours.
There are 24 hours in a day: 24/12 = 2 times a day.
Total daily dosage is 300 mg/dose x 2 doses = 600 mg per day.
Calculate the dosage per dose:
The medication is to be administered in divided doses every 12 hours.
There are 24 hours in a day: 24/12 = 2 times a day.
Dosage per dose is 600 mg / 2 doses = 300 mg per dose.
Determine the volume per dose:
The phenytoin oral suspension contains 125 mg per 5 mL.
The nurse needs to administer 300 mg per dose.
To find the volume per dose, we can set up a proportion:
125 mg / 5 mL = 300 mg / x mL
Cross-multiplying gives us:
125x = 1500
Dividing both sides by 125, we get:
x = 12 mL
Correct Answer is ["2"]
Explanation
Determine the total daily dosage:
The client is prescribed 30 mg of ketorolac.
Calculate the dosage per dose:
The medication is to be administered in a single dose.
Dosage per dose is 30 mg.
Determine the volume per dose:
The ketorolac injection contains 15 mg per mL.
The nurse needs to administer 30 mg per dose.
Divide 30 mg / 15 mg per mL = 2 mL per dose.
