Final answer:
To determine how long a 36-ounce bottle of antacid will last, we calculate the daily usage and divide the total ounces by the daily consumption. Taking 1/4 ounce every other hour from 0600 to 2200 results in 2 ounces used per day, making the bottle last for 18 days.
Step-by-step explanation:
The question asks to calculate how many days a 36-ounce bottle of antacid will last if a patient takes 1/4 ounce every other hour from 0600 to 2200. To answer this, we have to determine how many doses the patient takes per day and how many doses are in the entire bottle.
From 0600 to 2200 (a span of 16 hours), there are 8 doses (since the patient takes the medicine every other hour, which means 8 hours of dosing). Each dose is 1/4 ounce, so the total daily use is 8 doses × 1/4 ounce per dose = 2 ounces per day.
To find out how many days the bottle will last, we divide the total ounces in the bottle by the daily usage : 36 ounces ÷ 2 ounces per day = 18 days.
Therefore, the 36-ounce bottle of antacid will last for 18 days.
