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.)
Answer and Explanation

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 ["83"]

Explanation

Here's how to calculate the infusion pump rate (mL/hour) for the penicillin G administration:

We know:

Total penicillin G dose: 20 million units (given)

Total volume of saline solution: 2 liters (given) = 2000 mL (convert liters to mL)

Penicillin G concentration in saline delivered by pharmacy: 10 million units/liter (given)

We need to find:

Infusion rate (mL/hour)

Steps:

Calculate the concentration of penicillin G in the final infusion solution:

We cannot directly add the penicillin G units to the saline volume because they represent different quantities. Penicillin G is measured in units, while saline volume is measured in liters (or mL).

We need to find the total volume of saline containing the prescribed dose of penicillin G:

We know the total penicillin G dose (20 million units) and the concentration of penicillin G in the saline delivered by pharmacy (10 million units/liter).

Volume of saline containing the dose (liters) = Total penicillin G dose (units) / Concentration of penicillin G in saline (units/liter)

Volume of saline containing the dose (liters) = 20 million units / 10 million units/liter

Volume of saline containing the dose (liters) = 2 liters (This confirms we received the correct concentration from the pharmacy to deliver the prescribed dose)

Correct Answer is ["0.6"]

Explanation

Here's the corrected calculation for the volume to be administered:

Dosage: 60 mg

Concentration: 100 mg/mL

Volume to administer:

Volume (mL) = Dosage (mg) / Concentration (mg/mL)

Volume (mL) = 60 mg / 100 mg/mL

Volume (mL) = 0.6 mL

Therefore, the nurse should administer 0.6 mL of enoxaparin sodium injection.
