How many ml of KCL 2 mEq/ml are needed if the dose is 30 mEq?

To determine how many milliliters of potassium chloride (KCL) at a concentration of 2 mEq/ml are needed for a dose of 30 mEq, you can use the formula:

[

\text{Volume (ml)} = \frac{\text{Dose (mEq)}}{\text{Concentration (mEq/ml)}}

]

In this case, the dose required is 30 mEq, and the concentration is 2 mEq/ml. Plugging the values into the formula provides:

[

\text{Volume (ml)} = \frac{30 \text{ mEq}}{2 \text{ mEq/ml}} = 15 \text{ ml}

]

This calculation shows that you need 15 ml of KCL to achieve the desired dose of 30 mEq. Understanding how to use this calculation is crucial for ensuring the correct dosage in clinical settings, reinforcing the importance of unit conversions and dimensional analysis in pharmacy practice.
