Final answer:
The patient will receive 162 mg of Aspirin per dose BID, resulting in a total of 324 mg per day after converting from grams to milligrams and accounting for the twice-a-day prescription.
Step-by-step explanation:
To find out how many milligrams (mg) a patient will receive per day of Aspirin when the prescription is for 0.162g (grams) PO (by mouth) BID (twice a day), we must convert grams to milligrams and then calculate the total daily intake. There are 1000 mg in 1g, so 0.162g is equivalent to 0.162 × 1000 mg, which equals 162 mg. As the patient is directed to take this dosage twice a day, we multiply by 2 to get the total daily dosage.
Therefore, the patient will receive 162 mg BID, which is 162 mg taken twice a day, resulting in a total of 324 mg per day.
