A nurse is assisting with the care of a client who has a prescription for 3,000 mL of intravenous fluids over the next 24 hours.
The nurse should set the volumetric pump to deliver how many milliliters per hour?
A. 125 mL/hr.
B. 130 mL/hr.
C. 135 mL/hr.
D. 140 mL/hr.
The correct answer and Explanation is :
To determine the correct flow rate for administering 3,000 mL of intravenous fluids over 24 hours, you can use the formula:
[
\text{Flow rate (mL/hr)} = \frac{\text{Total volume (mL)}}{\text{Total time (hr)}}
]
Given:
- Total volume = 3,000 mL
- Total time = 24 hours
Substituting the values into the formula:
[
\text{Flow rate} = \frac{3000 \text{ mL}}{24 \text{ hr}} \approx 125 \text{ mL/hr}
]
Thus, the correct answer is A. 125 mL/hr.
Explanation:
- Volume and Time: The total volume of fluids to be administered (3,000 mL) needs to be divided by the total time over which it should be given (24 hours). This calculation is essential for ensuring that the client receives the appropriate amount of fluid at a controlled rate, preventing complications associated with rapid fluid administration.
- Infusion Pump Use: In a clinical setting, a volumetric pump is often used to deliver intravenous fluids. The pump can be programmed to dispense a specific volume at a set rate, which helps maintain accuracy and safety in fluid administration.
- Clinical Implications: Administering fluids at the correct rate is critical in nursing practice. Over-infusion or under-infusion can lead to serious complications, including fluid overload, electrolyte imbalances, or inadequate hydration. Therefore, calculating the flow rate accurately is a key nursing responsibility.
- Monitoring: Once the pump is set to the calculated rate, the nurse should continuously monitor the infusion site, the client’s vital signs, and any signs of fluid overload or dehydration. This ensures that the therapy remains effective and safe.
In conclusion, the proper flow rate for delivering 3,000 mL of intravenous fluids over 24 hours is 125 mL/hr, making option A the correct choice.
