Answer
For Aspirin, the maximum dose is 0.6 g every 4 hours. There are 24 hours in a day, so:
Number of doses per day = ( \frac{24}{4} = 6 )
Total sodium intake from Aspirin = Maximum dose allowable x Number of doses per day
= 0.15 g x 6 = 0.9 g.
This is less than the RDA of 2.4 g.

Answer
For Paracetamol, the maximum dose is 1.0 g every 6 hours. Therefore:
Number of doses per day = ( \frac{24}{6} = 4 )
Total sodium intake from Paracetamol = Maximum dose allowable x Number of doses per day
= 0.43 g x 4 = 1.72 g.
This is still less than the RDA of 2.4 g.

Answer
Since both Aspirin (0.9 g) and Paracetamol (1.72 g) result in sodium intakes that are below the RDA of 2.4 g, the journalist’s statement is false for both medicines.
