Answer:
10 days
Explanation:
Begin by converting the total volume of the laxative medication lactulose and the dosage amount both to the common unit of measurement for medications, milliliters (mL).
The total volume of medication is 10 ounces (oz). 1 oz is the equivalent of 30 mL, represented as 1 oz = 30 mL
10 oz x 30 mL per oz = 300 mL of total medication available
The dosage amount is 1 tablespoon (Tbsp) twice a day -- BID is a Latin phrase standing for "bis in die" which translates to "two times daily." This means the patient is consuming 2 Tbsp per day. 1 Tbsp is the equivalent of 15 mL, represented at 1 Tbsp = 15 mL.
2 Tbsp x 15 mL per Tbsp = 30 mL per day
Next, divide the total amount of medication by the daily amount. 300 mL is the total amount. 30 mL per day is the daily amount.
300 mL ÷ 30 mL per day = 10 days
10 ounces of the laxative lactulose is a 10-day supply if prescribed at a dosage of 1 Tbsp BID.
