The initial dosage of a drug is 5 mg/kg of body weight. If a patient weighs 84 kg, what is the initial dosage in mg?

Rationale

The initial dosage in mg for a patient weighing 84 kg is 420 mg.

To find the initial dosage, multiply the dosage per kilogram (5 mg/kg) by the patient's weight (84 kg). This calculation results in 420 mg, which is the correct dosage for the patient.

A (81.4) YOUR ANSWER

This option is incorrect because it does not result from the calculation of the initial dosage. A possible error could be from dividing rather than multiplying the dosage per kg by the body weight, leading to an incorrect figure.

B (185) YOUR ANSWER

This choice also fails to reflect the correct calculation. It could be a miscalculation, perhaps resulting from using a different weight or dosage figure, but it does not correspond to the required 5 mg/kg multiplied by 84 kg.

C (420) CORRECT

This is the correct answer. By using the formula: dosage (5 mg/kg) × body weight (84 kg), the calculation yields 420 mg, which matches the required initial dosage.

D (925) YOUR ANSWER

This option is incorrect, likely arising from a miscalculation, such as mistakenly using a higher multiplier or weight. The calculation does not logically support this figure based on the provided dosage per kg and the weight of the patient.

Conclusion

The correct initial dosage for a patient weighing 84 kg is 420 mg, calculated by multiplying the weight by the dosage per kg. The other choices stem from miscalculations or misunderstandings of the formula required to determine the appropriate dosage, emphasizing the importance of precise calculations in medical dosing.
