The health care provider prescribes 10 milliliters of medication to be administered to the child every 8 hours. The mother calls the clinic later in the day and asks how to measure 5 milliliters
The nurse would instruct the mother to administer how many teaspoons of the medication?
____ teaspoons
Record the answer rounding to the nearest whole number.
Correct Answer: 2
1 teaspoon = 5 milliliters; 10 milliliters divided by 5 = 2 teaspoons. This problem can be set up with what you have on one side and what you need on the other side of the equation. What you have is 1 tsp:5 milliliters, what you want to know is x teaspoons:10 mL. The equation would be 1:5 = x:10. Multiply the two numbers on either end of the equation (1 X 10) and then make that equal to the multiplication of the 2 inside figures (5 X x), resulting in the equation 10 = 5x. Divide both sides by 5 to leave only the x on one side of the equation (10 ÷ 5 = 5x ÷ 5), resulting in 2 = x.
