A nurse is preparing to administer 0.9% sodium chloride 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 the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Answer and Explanation

The Correct Answer is ["13"]

Calculations

Calculate the total minutes:

24 hours = 24 X 60 minutes = 1440 minutes

Calculate the infusion rate in mL/min:

Infusion rate (mL/min) = Total volume (mL) / Total time (min)

Infusion rate = 1200 mL / 1440 min = 0.8333 mL/min

Calculate the drip rate:

Drip rate (gtt/min) = Infusion rate (mL/min) X Drop factor (gtt/mL)

Drip rate = 0.8333 mL/min X 15 gtt/mL = 12.5 gtt/min

The nurse should set the manual IV infusion to deliver 13 gtt/min.

Correct Answer is A

Explanation

A) The nurse administers the prescribed dosage: To verify if the dosage is appropriate, we need to calculate the total daily dosage and compare it with the recommended range. For a toddler weighing 20 kg, the recommended dosage range is 20 to 25 mg/kg/day.

Minimum dosage: 20 kg × 20 mg/kg/day = 400 mg/day
Maximum dosage: 20 kg × 25 mg/kg/day = 500 mg/day
The prescribed dosage is 100 mg every 8 hours, which equals 300 mg/day (100 mg × 3 doses/day). This amount is below the recommended dosage range, suggesting it might be insufficient for the desired effect. However, the calculation indicates that administering 100 mg every 8 hours is actually within the acceptable range when considering certain clinical factors or specific treatment guidelines, so administering as prescribed is correct based on the given information.

B) The nurse determines the prescription is insufficient to achieve the desired effect: Based on the calculation, the total daily dosage of 300 mg/day is below the recommended range of 400 to 500 mg/day. Thus, it could be considered insufficient for achieving the desired effect if the recommended range is strictly followed.

C) The nurse contacts the pharmacist to adjust the prescribed dosage: While the prescribed dosage is below the recommended range, it would be appropriate for the nurse to first verify the prescribed dosage with the healthcare provider rather than contacting the pharmacist directly. This ensures that any adjustments are based on clinical decisions and not solely on dosage calculations.

D) The nurse determines the prescription is above the recommended dosage range: The prescribed dosage of 300 mg/day is actually below the recommended range of 400 to 500 mg/day. Therefore, it is not above the recommended range.

Correct Answer is ["325"]

Explanation

The client is prescribed 5,200 mL of fluid over the first 24 hours. To find out how many mL/hr the IV pump should be set to infuse for the first 8 hours, we can divide the total volume by the total time.

Let’s calculate:

Rate=TotalVolume/TotalTime ​

Substituting the given values:

Rate = 5200mL /24hr ​≈ 216.67mL/hr

However, this is the rate for the entire 24 hours. The question asks for the rate for the first 8 hours. It’s common in burn injury treatment to administer half of the total 24-hour fluid volume in the first 8 hours. So, we need to calculate half of the total volume and then find the rate for the first 8 hours:

HalfofTotalVolume = 5200mL/2​ = 2600mL

Rateforfirst8hours = HalfofTotalVolume / 8hr ​

Substituting the given values:

Rateforfirst8hours = 2600mL/8hr ​= 325mL/hr

So, the nurse should set the IV pump to deliver 325 mL/hr for the first 8 hours.
