Final answer:
Given the patient's prescription of 2 tsps of cough suppressant every 6 hours for 8 days and the fact that each medication bottle contains 8 fl oz, the patient will need to purchase 2 bottles of medication to complete the 8 days.
Explanation:
The first thing we need to do is determine how many doses of the cough suppressant the patient will take over the 8 day period. Given that the patient is instructed to take 2 teaspoons of medication every 6 hours, this means the patient will be taking 4 doses each day. Over 8 days, this totals to 4 doses/day * 8 days = 32 doses.
Next, we need to convert the total number of doses into fluid ounces since the medication bottle is measured in this unit. There are 6 teaspoons in 1 fluid ounce, so each dose of 2 teaspoons equals 1/3 of a fluid ounce. This sums up to 32 doses * 1/3 fl oz/dose = 10.67 fluid ounces in total.
Finally, since each bottle of medication contains 8 fluid ounces, the patient will need more than one bottle to complete the order. To determine the exact number, divide the total fluid ounce needs by the fluid ounces per bottle. Therefore, 10.67 fl oz / 8 fl oz/bottle = 1.33 bottles are needed. However, as we cannot purchase a fraction of a bottle, the patient will need to buy 2 full bottles to complete the 8 days of medication.
