Questions: Mr. Glum has been started on furosemide (Lasix) 5 mg IV q 12 h. If available preparation of the medication is 2500 mcg / ml. How much should the nurse prepare to administer? A. 1.0 ml B. 2.5 ml C. 0.8 ml D. 2.0 ml

Solution Steps

To determine the volume of medication the nurse should prepare, we need to convert the prescribed dose from mg to mcg and then use the concentration of the available preparation to find the volume in ml.

1. Convert the prescribed dose from mg to mcg.
2. Use the concentration of the medication to calculate the required volume.

The prescribed dose is \(5 \, \text{mg}\). To convert this to micrograms (mcg), we use the conversion factor \(1 \, \text{mg} = 1000 \, \text{mcg}\).

\[ 5 \, \text{mg} \times 1000 \, \frac{\text{mcg}}{\text{mg}} = 5000 \, \text{mcg} \]

The available preparation of the medication has a concentration of \(2500 \, \text{mcg/ml}\). To find the volume in milliliters (ml) that corresponds to the prescribed dose, we use the formula:

\[ \text{Volume} = \frac{\text{Prescribed Dose}}{\text{Concentration}} \]

Substituting the values:

\[ \text{Volume} = \frac{5000 \, \text{mcg}}{2500 \, \text{mcg/ml}} = 2.0 \, \text{ml} \]
