For a client receiving metronidazole, if the client weighs 146.6 pounds, what rate should the nurse program the IV pump?

• A. 150 mL/hr
• B. 200 mL/hr
• C. 250 mL/hr
• D. 300 mL/hr

Answer: (B)

To determine the correct IV pump rate for a client receiving metronidazole, it's important to consider the recommended dosing regimen for the medication, which can be influenced by the client's weight and clinical indications for therapy. Metronidazole is often administered intravenously when oral administration is not possible or for specific indications such as severe infections.

In general practice, the standard dosing for metronidazole IV is guided by patient weight. The dosing is typically calculated based on a milligram per kilogram (mg/kg) basis. A common regimen is 500 mg administered every 8 hours, which would be appropriate for most adult patients requiring treatment for various infections.

Given that a dose has been determined and taking into account the weight of the client, the calculation would involve determining how many mL/hour is needed to deliver the correct amount based on the concentration of the metronidazole solution used.

Assuming the client weighs approximately 66.5 kg (which is 146.6 pounds), if we follow a common dosing strategy, the appropriate rate of administration, factoring in both the fluid requirement and the medication concentration, would be at the 200 mL/hr rate.

This value effectively reflects a balance between achieving therapeutic levels of the medication in the bloodstream while
