An older adult client admitted with community-acquired pneumonia has a scheduled dose of intravenous levofloxacin. The medication arrives from the pharmacy as a $500 \text{ mg}$ dose premixed in a $100 \text{ mL}$ bag of $5\% \text{ Dextrose}$ in Water ( $\text{D}_5\text{W}$ ). According to the administration instructions, the medication must infuse steadily over $90$ minutes.

At what rate, in $\text{mL/hr}$ , should the infusion pump be programmed?

Record answer to the nearest tenth. Do not include units in answer.

Cevap: 66.7 mL/hr

Cevap

The infusion pump should be programmed to a rate of

66.7

To determine the correct IV pump setting in

\text{mL/hr}

, the total volume of the infusion (

100 \text{ mL}

) must be divided by the total time in minutes (

90

minutes) and then multiplied by

60

(the number of minutes in an hour). This yields

66.666... \text{ mL/hr}

. Rounding to the nearest tenth provides the final correct value of

66.7

Adım Adım Çözüm

Identify the total volume to be infused.

The total fluid volume is

100 \text{ mL}

The rate calculation relies on the total fluid volume of the IV bag, not the mass of the medication.

Identify the designated infusion time.

The infusion time is

90

minutes.

This determines the duration over which the volume must be delivered.

Set up the standard formula for an IV pump rate.

\frac{100 \text{ mL}}{90 \text{ minutes}} \times 60 \text{ minutes/hour}

Infusion pumps are programmed in milliliters per hour (

\text{mL/hr}

), so the time in minutes must be converted.

Calculate the continuous rate.

1.111... \times 60 = 66.666... \text{ mL/hr}

This provides the exact hourly rate required to deliver the medication over the specified timeframe.

Apply the rounding instructions.

66.7

The prompt explicitly requires rounding to the nearest tenth for safe and accurate pump programming.
