Step 1: Convert the patient's weight from pounds to kilograms.
175 \text{ pounds} \times \frac{0.45 \text{ kg}}{1 \text{ pound}} = 78.75 \text{ kg}
We know that 1 pound is approximately equal to 0.45 kilograms. So, a patient weighing 175 pounds would weigh:
Step 2: Calculate the total daily dosage in milligrams.
10 \mathrm{mg} / \mathrm{kg} \times 78.75 \text{ kg} = 787.5 \mathrm{mg}
For a patient weighing 78.75 kg, the total daily dosage would be:
Final Answer
