Answer :
Final answer:
To prepare a 64 mEq dose of medication from a solution with a concentration of 40 mEq / 10 mL, 4 mL of the medication is required.
Explanation:
To calculate the volume of medication needed to deliver a 64 mEq dose from a concentration of 40 mEq / 10 mL, we use the formula C1V1 = C2V2 where C1 and V1 are the initial concentration and volume and C2 and V2 are the desired concentration and volume respectively.
Substituting the given values, we have:
40 mEq/10 mL = 64 mEq/V2
Now, solving for V2 (the unknown volume for the 64 mEq dose) we get:
V2 = 64 mEq * 10 mL / 40 mEq
This simplifies to:
V2 = 160 mL / 40
V2 = 4 mL
This means that 4 mL of the medication is required to deliver a 64 mEq dose.
