Answer to Question #250094 in Physics for Midnight

Question

Hydroxychloroquine is commonly used for treatment of malaria. It is prescribed that it should only be taken every four times per week and the safe dosage per week is only 2000 mg for children of 6 years to 11 years old. If a parent has given her child a dosage of 0.25 grams of the medicine every Monday, Wednesday, Friday , Sunday ( every other day thereafter ) for two weeks, can we say that the dosage given is tolerable and is still safe? Why or Why not?

Answer 1

Let us find the total mass the child received during 2 weeks remembering that 0.25 g are 250 mg:

$$250·7=1750\text{ mg}.$$

We multiplied by 7 cause every other day during 2 weeks is Mon, We, Fri, Sun, Tue, Thu, Sat.

Therefore, this is a safe and tolerable dose because it's smaller than 200 mg.
