The doctor orders Lactulose $25 \mathrm{~g}$. The drug label reads $10 \mathrm{~g} / 15 \mathrm{~mL}$. The proper dose in tablespoons is

Step 1 ：The doctor orders Lactulose 25 g. The drug label reads 10 g / 15 mL. We need to find the proper dose in tablespoons.

Step 2 ：First, we need to convert the doctor's order from grams to milliliters using the drug label. We know that 10 g is equivalent to 15 mL, so 25 g would be \(\frac{25}{10} \times 15 = 37.5\) mL.

Step 3 ：Next, we need to convert milliliters to tablespoons. We know that 1 tablespoon is approximately 14.79 milliliters. So, \(\frac{37.5}{14.79} = 2.54\) tablespoons.

Step 4 ：However, in medical practice, it's usually rounded to the nearest whole or half tablespoon for practicality. So, we round 2.54 to 2.5.

Step 5 ：Final Answer: The proper dose in tablespoons is approximately \(\boxed{2.5}\).
