The healthcare provider prescribes one liter of 1/4 strength saline in 5% dextrose solution (D5 1/4 NS) to infuse at a keep-open rate over 24 hours. The IV administration set delivers 15 gtt/mL. The nurse should regulate the infusion pump to deliver how many mL/hr? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["42"]
Calculation:
Convert liters to milliliters:
1 liter (L) = 1000 milliliters (mL)
Calculate the infusion rate in mL/hr:
Infusion rate (mL/hr) = Total volume (mL) / Total time (hours)
= 1000 mL / 24 hours
= 41.67 mL/hr
Round to the nearest whole number:
= 42 mL/hr

Correct Answer is ["0.5"]
Explanation
Calculation:
Identify the desired dose:
Desired dose = 1 mg
Available concentration = 2 mg/mL
Calculate the volume to administer:
Volume to administer (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 1 mg / 2 mg/mL
= 0.5 mL
Correct Answer is ["8"]
Explanation
Calculation:
Dose per administration = 20 mg
Available dose per tablet = 10 mg/tablet
Calculate the number of tablets to administer per dose:
Tablets per dose = Dose per administration / Available dose per tablet
= 20 mg / 10 mg/tablet
= 2 tablets
Calculate the total number of tablets to administer in a 24-hour period:
Total tablets per day = Tablets per dose x Number of doses per day
= 2 tablets/dose x 4 doses/day
= 8 tablets
