Question

a liquid medication is available in a 120 ml bottle, and the prescription is for 2 teaspoons (10 ml) every 6 hours for 5 days. how many bottles are needed for the full course of treatment?
o 1 bottle
√ 2 bottles
o 3 bottles
o 4 bottles

Explanation:

Step1: Calculate total number of doses

There are 24 hours in a day. For 5 days, the total number of hours is $24\times5 = 120$ hours. Since the dose is every 6 hours, the number of doses is $\frac{120}{6}=20$ doses.

Step2: Calculate total volume of medication needed

Each dose is 10 mL, so the total volume of medication needed is $20\times10 = 200$ mL.

Step3: Calculate number of bottles

Each bottle is 120 mL. $\frac{200}{120}=\frac{5}{3}\approx1.67$. Since we can't have a fraction of a bottle, we need 2 bottles.

Answer:

2 bottles
