The dosage of a drug is determined by the weight of the patient. The dosage is 2 mg per kg of body weight.

What is the dosage for a patient with a body weight of 55 kg?

What is the dosage for a patient with a body weight of 80 kg?

Answer :

To determine the correct dosage of the drug for each patient, we need to use the given dosage rate, which is 2mg per kilogram of body weight.

Let's break it down step-by-step for each patient:

1. For the patient weighing 55kg:
- The dosage rate is 2mg of the drug per kg of body weight.
- Multiply the patient's weight by the dosage rate:
[tex]\[
55 \, \text{kg} \times 2 \, \text{mg/kg} = 110 \, \text{mg}
\][/tex]
- Therefore, the dosage for a patient weighing 55kg is 110mg.

2. For the patient weighing 80kg:
- Again, use the dosage rate of 2mg per kg.
- Multiply the patient's weight by the dosage rate:
[tex]\[
80 \, \text{kg} \times 2 \, \text{mg/kg} = 160 \, \text{mg}
\][/tex]
- Therefore, the dosage for a patient weighing 80kg is 160mg.

In summary, the patient who weighs 55kg should receive 110mg of the drug, and the patient who weighs 80kg should receive 160mg.
