Answer :
Based on the dosage available, the amount in mL of the drug required is 22.5 mL.
What is drug dosage?
Drug dosage refers to the amount of drug that should be taken by a patient in order to produce effective pharmacodynamic results.
The dosage of the drug to be given is 45 mEq.
The dosage available is 30 mEq in 15 mL.
In order to give this required dosage the amount in mL required is calculated as follows:
30 mEq is in 15 mL
45 mEq will be in x mL
x = 45 * 15/30
x = 22.5 mL
In conclusion, drug dosage refers to the amount of drug required to produce good results in the patient.

Final answer:
To give the ordered 45 mEq dose when the available dose is 30 mEq in 15 mL, you administer 22.5 mL of the medication.
Explanation:
You have been asked to calculate the volume of medication to administer based on an ordered dosage and the concentration of the drug available. The order is to administer 45 mEq of a medication, and the available dosage form contains 30 mEq in 15 mL. To find the required volume to administer the prescribed dosage, you can set up a proportion using the given concentrations:
Ordered mEq: 45 mEq = Unknown mL (X)
Available mEq: 30 mEq = 15 mL
Now, solve for X (the unknown mL) by cross-multiplication:
(30 mEq) × (X mL) = (45 mEq) × (15 mL)
X = (45 × 15) / 30
X = 22.5 mL
Therefore, you would administer 22.5 mL of the available drug to provide the prescribed 45 mEq dose.
