Answer :
Final answer:
To calculate the quantity to be administered, set up a proportion using the labeled concentration and the desired amount of Slo-K. Cross-multiply and solve for x to find x = 10 mL. Therefore, the quantity to be administered is 10 mL of the liquid supply.
Explanation:
The prescription order is Slo-K 20 mEq PO bid and the supply is a liquid labeled 30 mEq per 15 mL. To determine the quantity to be administered, we need to calculate the amount of liquid needed to deliver 20 mEq of Slo-K.
Since the liquid is labeled as 30 mEq per 15 mL, we can set up a proportion to find the amount of liquid needed for 20 mEq:
30 mEq / 15 mL = 20 mEq / x mL
Cross-multiplying and solving for x, we get:
x = 15 mL (20 mEq) / 30 mEq
x = 10 mL
Therefore, the quantity to be administered is 10 mL of the liquid supply.
