Question

scenario
mrs. turner’s daily medications include potassium chloride 10 meq tablet by mouth once daily. the hospital pharmacy will dispense potassium chloride liquid 10% (1.5 gram or 20 meq per 15 ml). the kcl liquid will be further diluted in a 6 oz glass of water or juice for administration.
question
what volume of the kcl 10% liquid should be used for mrs. turner’s usual daily dose?

Explanation:

Step1: Identify the dosage relationship

We know that the liquid has 20 mEq per 15 mL, and we need to find the volume for 10 mEq. Let the volume be \( V \).
The ratio of mEq to volume should be constant, so \(\frac{20\ \text{mEq}}{15\ \text{mL}}=\frac{10\ \text{mEq}}{V}\)

Step2: Solve for \( V \)

Cross - multiply: \( 20\times V = 10\times15 \)
\( 20V=150 \)
Divide both sides by 20: \( V=\frac{150}{20}=7.5\ \text{mL} \)

Answer:

The volume of the KCl 10% liquid should be 7.5 mL.
