A client with mild fluid retention is prescribed furosemide $30\text{ mg}$ by mouth every morning. The client's morning vital signs include a blood pressure of $122/78\text{ mmHg}$ and a heart rate of $76\text{ beats/min}$ , with a recent serum potassium level of $4.1\text{ mEq/L}$ . The pharmacy delivers furosemide oral solution labeled $40\text{ mg}$ per $5\text{ mL}$ . How many milliliters (mL) should the practical nurse administer for the morning dose? Record your answer to the nearest tenth. Do not include units in your answer.

Cevap: 3.8 mL

Cevap

The practical nurse should administer

3.8\text{ mL}

of the furosemide oral solution.

The correct answer is derived by applying the standard dosage calculation formula

\frac{\text{Desired}}{\text{Have}} \times \text{Quantity}

. Substituting the given values (

\frac{30\text{ mg}}{40\text{ mg}} \times 5\text{ mL}

) yields

3.75\text{ mL}

. Rounding to the nearest tenth gives

3.8

. The vital signs and potassium level provided (

4.1\text{ mEq/L}

) are within normal limits, confirming it is safe for the practical nurse to proceed with the administration.

Adım Adım Çözüm

Identify the prescribed dose and available concentration from the scenario.

Desired =

30\text{ mg}

, Have =

40\text{ mg}

, Quantity =

5\text{ mL}

Accurate extraction of clinical data is required before performing any medication calculation.

Apply the standard dosage calculation formula:

\frac{\text{Desired}}{\text{Have}} \times \text{Quantity}

\frac{30\text{ mg}}{40\text{ mg}} \times 5\text{ mL} = 3.75\text{ mL}

This formula determines the exact liquid volume needed to deliver the prescribed dose safely.

Round the final answer to the nearest tenth according to the instructions.

3.75\text{ mL}

rounds to

3.8\text{ mL}

Liquid medications measured in small syringes are typically rounded to the nearest tenth for precise administration, adhering to standard rounding rules where the hundredths place is

5

or greater.
