To determine the total dose in milligrams, you need to multiply the dosage per kilogram by the patient's weight in kilograms.

In this case, the physician has ordered a dosage of 2 mg/kg for a patient who weighs 70 kg. To find the total dose, the calculation would be:

Total Dose = Dosage per kg × Weight in kg

Total Dose = 2 mg/kg × 70 kg

Carrying out the multiplication:

Total Dose = 140 mg

Thus, the total dose for this patient is 140 mg, making it the correct answer.
