What volume, in tsp, of a 20 mEq/15 mL solution would deliver a dose of...

To calculate:

20 mEq per 15 mL

We need 40 mEq, so:

(40 mEq)÷(20 mEq)=2×15 mL=30 mL(40 \, \text{mEq}) \div (20 \, \text{mEq}) = 2 \times 15\, \text{mL} = 30\, \text{mL}(40mEq)÷(20mEq)=2×15mL=30mL

Now, convert to teaspoons:

1 tsp = 5 mL

30 mL ÷ 5 = 6 tsp

This type of dosage conversion is covered in Pharmacy Technician Certification Exam Review, under Pharmaceutical Calculations.
