Final answer:
To calculate the mg/dose of ferrous sulfate, divide the total daily dose by 2. The mg/dose is approximately 16.1mg.
Step-by-step explanation:
To calculate the mg/dose of ferrous sulfate, we need to follow the given physician's orders. The dosage is 3mg/kg/day divided in doses q 12hrs. The patient weighs 23lbs 10oz, which is equivalent to 23.625lbs. To convert lbs to kg, we divide the weight in lbs by 2.2046. So, the patient's weight in kg is approximately 10.71kg. Next, we calculate the total daily dose by multiplying the weight in kg by the prescribed dosage. So, the total daily dose is 32.13mg (3mg/kg/day x 10.71kg). Since the dosage is divided into doses q 12hrs, we divide the total daily dose by 2 to get the mg/dose. So, the mg/dose is approximately 16.07mg (32.13mg/2). Rounding to the tenth, the answer is 16.1mg/dose.
