Final answer:
The patient will take 2 tablespoonfuls of KCl, since 1 tablespoon is equivalent to 15 mL, and they are prescribed 30 mL of KCl per day.
Step-by-step explanation:
The question involves converting milliliters to tablespoonfuls, which is a simple mathematical conversion problem.
A patient is given 30 mL of KCL (potassium chloride) once a day. If 1 tablespoon is equivalent to 15 mL, then the number of tablespoonfuls the patient will take can be found by dividing the total milliliters by the number of milliliters in one tablespoonful:
30 mL ÷ 15 mL/tablespoon = 2 tablespoonfuls
Therefore, the patient will take 2 tablespoonfuls of KCl.
