How many mL of a concentrated vial containing 4.4 mEq/mL of Ca Gluconate is needed to add 45 mEq to an IV bag?

How many mL of a concentrated vial containing 4.4 mEq/mL of Ca Gluconate is needed to add 45 mEq to an IV bag?

• A. 10.23 mL
• B. 15 mL
• C. 20.25 mL
• D. 8.5 mL

Answer: (A)

To determine how many milliliters of the concentrated vial containing 4.4 mEq/mL of Calcium Gluconate are needed to achieve a total of 45 mEq, you can use the formula: Volume (mL) = Total mEq required / Concentration (mEq/mL) Plugging in the values: Volume (mL) = 45 mEq / 4.4 mEq/mL Calculating this gives: Volume (mL) = 10.227 mL Rounding this to two decimal places yields 10.23 mL. This calculation is crucial because it helps ensure that the correct dosage of the medication is administered, which is vital for patient safety and therapeutic efficacy. The other answer choices represent volumes that do not correspond to the correct calculation based on the concentration given in the question. Understanding how to derive the correct volume based on mEq/mL concentration is essential for pharmacy technicians to accurately prepare IV medications.
