A nurse is preparing to administer ampicillin/sulbactam 15 g via intermittent IV bolus, Available is ampicillin-sulbactam 1.5 g in 0.9% sodium chloride 100 mL to infuse over 30 min. The nurse should set the IV infusion pump to deliver how many mL/h? Mound the answer to the nearest whole number. Use a leading zero if it applies in not use a trailing zero)
The correct answer and Explanation is :
To solve this problem, we first need to calculate the IV infusion rate in milliliters per hour (mL/h).
Given Information:
- Dosage available: 1.5 g of ampicillin/sulbactam in 100 mL of 0.9% sodium chloride.
- Time to infuse: 30 minutes.
We want to determine the infusion rate in mL/h.
Step-by-Step Calculation:
- Convert infusion time from minutes to hours:
[
30 \, \text{minutes} = 0.5 \, \text{hours}
] - Calculate the IV pump rate:
The IV pump delivers 100 mL over 30 minutes (or 0.5 hours). To find the rate in mL/h, divide the volume (100 mL) by the infusion time in hours (0.5 hours): [
\text{Rate} = \frac{100 \, \text{mL}}{0.5 \, \text{hours}} = 200 \, \text{mL/h}
]
Answer:
The nurse should set the IV infusion pump to 200 mL/h.
Explanation:
- IV Infusion Rate Formula: The general formula for IV infusion rate calculation is:
[
\text{Rate (mL/h)} = \frac{\text{Total Volume (mL)}}{\text{Time (hours)}}
]
This formula helps determine the speed at which the IV pump should deliver the solution. - Volume and Time Conversion: Since the nurse needs to infuse 100 mL over 30 minutes, converting the time to hours is essential for calculating the pump rate in mL/h.
- Safety Considerations: It is important for the nurse to set the IV pump correctly to ensure the medication is administered over the intended duration, preventing complications such as overdose or underdose.
Always double-check infusion rates in real-world practice to ensure accuracy and patient safety.
