Question: 1 / 400

If a patient should receive a medication at 15mg/kg/day in 3 equally divided doses, what will the approximate dose for a 142lb patient be?

968mg

323mg

The approximate dose for a 142lb patient will be 323mg.

To calculate this, first convert the weight from pounds to kilograms by dividing it by 2.2. In this case, 142/2.2 = 64.5kg.

Then multiply this number by 15 to get the total amount of medication needed for the day, which is 967.5mg.

Finally, divide this by 3 to get the dose per administration, which is approximately 323mg.

Option A (968mg) is incorrect because it does not take into account the need for 3 equal doses per day.

Option C (2904mg) is incorrect because it incorrectly multiplies the weight in pounds by 15.

Option D (284mg) is incorrect because it incorrectly divides the total amount by the number of doses

2904mg

284mg
