Question 14

The recommended dosage for a person who weighs 84 kilograms is 336 milligrams.

To find the recommended dosage, multiply the weight of the person by the dosage per kilogram. For a person weighing 84 kilograms, the calculation is 4 mg/kg * 84 kg, resulting in a total of 336 milligrams.

A) 21

This option is incorrect as it significantly underestimates the dosage required. If we divide 21 milligrams by 84 kilograms, it suggests a dosage of approximately 0.25 mg/kg, which is far below the recommended 4 mg/kg.

B) 88

Option B is also incorrect. A dosage of 88 milligrams translates to about 1.05 mg/kg for an 84-kilogram person, which again is much lower than the recommended dosage of 4 mg/kg.

C) 324

This choice is incorrect as well. A dosage of 324 milligrams would equate to approximately 3.857 mg/kg, which is still less than the required 4 mg/kg and therefore does not meet the recommendation.

D) 336

This is the correct answer. The dosage of 336 milligrams is derived from the calculation of 4 mg multiplied by 84 kg, achieving the precise recommended dosage for the individual’s weight.

E) 2,100

Option E is incorrect. A dosage of 2,100 milligrams would imply a dosage of 25 mg/kg for an 84-kilogram person, which is excessively high compared to the recommended 4 mg/kg.

Conclusion

The correct answer, 336 milligrams, is the only option that accurately reflects the recommended dosage calculation based on the weight of the individual. All other options either understate or overstate the appropriate dosage, thus failing to align with the guidance of 4 milligrams per kilogram of body weight.
