How many pills does the patient need to take to get 625 mg of ibuprofen?

To calculate the number of pills a patient needs to take to get a 625 mg dosage of ibuprofen, we need to consider that each pill is 250 mg. The patient needs to take 625 mg twice daily.

Calculation to Determine the Number of Pills:

Given that each pill is 250 mg, we first need to determine how many pills the patient needs to take to reach 625 mg. To do this, we divide the required dosage by the dosage per pill:

625 mg / 250 mg = 2.5 pills

Since we can't have half a pill, we need to calculate how many whole pills and how many half pills the patient needs to take:

2 whole pills x 250 mg = 500 mg

1 half of a pill x 250 mg = 125 mg

So, the patient needs to take 2 whole pills and half of a pill to get the required 625 mg dosage of ibuprofen.
