Oral potassium chloride 10% solution contains 20 mEq of potassium per 15 mL of solution. A patient is prescribed 22 mEq of potassium daily. How many milliliters of potassium chloride 10% will the patient receive each day?

(Answer must be numeric; no units or commas.)

Answer :

Final answer:

The patient will receive 16.5 milliliters of potassium chloride 10% solution each day.

Explanation:

To calculate the number of milliliters of potassium chloride 10% solution the patient will receive each day, we can set up a proportion using the given information.


10% solution contains 20 mEq of potassium per 15 mL of solution. Therefore, the ratio of mEq to mL is 20/15 or 4/3.
The patient is prescribed 22 mEq of potassium daily, so we can set up the proportion:


(4 mEq / 3 mL) = (22 mEq / x mL)

By cross-multiplying and solving for x, we find that x = 16.5 mL. Therefore, the patient will receive 16.5 milliliters of potassium chloride 10% solution each day.
