A client with heart failure has a new prescription for furosemide $60\text{ mg}$ by mouth once daily. The pharmacy supplies furosemide oral solution with a concentration of $10\text{ mg}/1\text{ mL}$ . How many milliliters ( $\text{mL}$ ) should the practical nurse administer for each dose? Record your answer as a whole number. Do not include units in your answer.

Answer: 6 mL

Answer

To calculate the correct volume of furosemide oral solution, use the formula:

(\text{Desired} / \text{Have}) \times \text{Quantity}

. The desired dose is

60\text{ mg}

, the dose on hand is

10\text{ mg}

, and the quantity is

1\text{ mL}

. The calculation is

(60\text{ mg} / 10\text{ mg}) \times 1\text{ mL}

, which equals

6\text{ mL}

Step-by-Step Solution

Identify the prescribed dose (Desired).

60\text{ mg}

This is the amount of medication the provider ordered for the client.

Identify the available medication concentration (Have and Quantity).

10\text{ mg}

1\text{ mL}

This is the strength of the medication provided by the pharmacy.

Apply the dosage calculation formula:

(\text{Desired} / \text{Have}) \times \text{Quantity}

(60\text{ mg} / 10\text{ mg}) \times 1\text{ mL} = X

This formula accurately determines the correct volume to administer based on the required dose and available concentration.

Perform the calculation.

6\text{ mL}

Dividing

60

10

yields

6

, and multiplying by

1

maintains the value.
