The healthcare provider prescribes 2 L of 5% dextrose in water (DW).IV to infuse in 24 hours. The IV administration set delivers 15 gtt/mL. How many gtt/min should the nurse regulate the infusion? (Enter numerical value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["21"]
Here's how to calculate the infusion rate (gtt/min) for the nurse to regulate:
1. We know:
Total volume of D5W solution: 2 L (liters)
Infusion time: 24 hours
IV administration set gtt/mL: 15 gtt/mL
2. We need to find the infusion rate in gtt/min.
Steps:
a. Convert liters to milliliters (mL) for better calculation:
1 liter = 1000 mL
Total volume (mL) = 2 L * 1000 mL/L
Total volume (mL) = 2000 mL
b. Convert infusion time from hours to minutes:
Infusion time (minutes) = Infusion time (hours) x Minutes per hour
Infusion time (minutes) = 24 hours * 60 minutes/hour
Infusion time (minutes) = 1440 minutes
c. Calculate the total volume of solution to be infused per minute:
Volume rate (mL/min) = Total volume (mL) / Infusion time (minutes)
Volume rate (mL/min) = 2000 mL / 1440 minutes
Volume rate (mL/min) = 1.389 mL/min (round to nearest hundredth)
d. Finally, calculate the infusion rate in gtt/min:
Infusion rate (gtt/min) = Volume rate (mL/min) x gtt/mL
Infusion rate (gtt/min) = 1.389 mL/min * 15 gtt/mL
Infusion rate (gtt/min) = 20.835 gtt/min (round to nearest whole number as requested)
Therefore, the nurse should regulate the infusion at approximately 21 gtt/min

Correct Answer is ["1.20"]
Explanation
First, we need to convert the client’s weight from pounds to kilograms since the dosage is prescribed in mg/kg. We know that 1 kg is approximately 2.20462 pounds. So,
Weightinkg = Weightinpounds / 2.20462 = 132/ 2.20462 ≈ 59.87kg
The prescribed dosage is 1 mg/kg every 12 hours, so the total daily dosage (for 24 hours) in mg would be:
Dailydosageinmg= 2 × (Dosageperkg × Weightinkg) = 2 × (1mg/kg × 59.87kg) ≈ 119.74mg
The medication is available in a concentration of 60 mg/0.6 mL, which simplifies to 100 mg/mL. Therefore, the volume to be administered per day in mL would be:
VolumeinmL=Dailydosageinmg/ Concentrationinmg/mL = 119.74mg / 100mg/mL ≈ 1.20mL
So, the nurse should administer approximately 1.20 mL of enoxaparin per day. Always consult with a healthcare professional for accurate information.
Correct Answer is ["20"]
Explanation
1. Convert client weight to kilograms (kg):
Client weight (lbs) = 178
We know 1 kg = 2.2 lbs
Client weight (kg) = 178 lbs / 2.2 lbs/kg = 81.36 kg (rounded to two decimal places for accuracy)
2. Calculate the total diltiazem dosage:
Dosage per kg = 0.25 mg/kg
Client weight (kg) = 81.36 kg
Total dosage (mg) = Dosage per kg * Client weight (kg)
Total dosage (mg) = 0.25 mg/kg * 81.36 kg = 20.34 mg (rounded to two decimal places for accuracy)
3. Round the dosage to the nearest whole number for administration:
Total dosage (mg) = 20.34 mg (rounded to two decimal places)
In practice, medication dosages are typically rounded to the nearest whole number for safe and accurate administration. Therefore, the nurse should administer 20 mg of diltiazem.
