Worked Solution & Example Answer:A journalist studied the data in Table 2 - AQA - A-Level Biology - Question 4 - 2020 - Paper 3
Step 1
Evaluate maximum sodium intake from Aspirin
Answer
The maximum dose of Aspirin allowed is 0.6 g every 4 hours. In a 24-hour period, the maximum number of tablets an adult can take is:
[ \frac{24 \text{ hours}}{4 \text{ hours/tablet}} = 6 \text{ tablets} ]
Total sodium intake from Aspirin:
[ 6 \text{ tablets} \times 0.15 ext{ g} = 0.9 ext{ g} ]
Since 0.9 g is less than the RDA of 2.4 g, the journalist is incorrect regarding Aspirin.
Step 2
Evaluate maximum sodium intake from Paracetamol
Answer
The maximum dose of Paracetamol allowed is 1.0 g every 6 hours. The maximum number of tablets an adult can take in a 24-hour period is:
[ \frac{24 \text{ hours}}{6 \text{ hours/tablet}} = 4 \text{ tablets} ]
Total sodium intake from Paracetamol:
[ 4 \text{ tablets} \times 0.43 ext{ g} = 1.72 ext{ g} ]
Since 1.72 g is also less than the RDA of 2.4 g, the journalist is incorrect regarding Paracetamol.
