Question

the nurse is preparing a dose of cefaclor 500 mg oral suspension using a clients medication bottle labeled, \125 mg/5 ml.\ how many ml should the nurse administer? (enter numeric value only. if rounding is required, round to the nearest whole number.)

Explanation:

Step1: Set up the proportion

Let \( x \) be the volume in mL to administer. The concentration is \( 125 \, \text{mg/5 mL} \), so we have the proportion \(\frac{125 \, \text{mg}}{5 \, \text{mL}}=\frac{500 \, \text{mg}}{x \, \text{mL}}\).

Step2: Cross - multiply and solve for \( x \)

Cross - multiplying gives \( 125x = 500\times5 \). Then \( 125x=2500 \). Dividing both sides by 125, we get \( x=\frac{2500}{125}=20 \).

Answer:

20
