Mr. Parks is 62 -year-old retired teacher who has recently been diagnosed with hepatic encephalopathy. His physician has prescribed lactulose $45 \mathrm{~mL}$ three or four times daily and has told Mr. Parks to adjust the amount of the medication so that he has three to four soft stools a day. A month later, Mr. Parks returns to the clinic and states that he has been taking only half of the medication once a day because he dislikes having more than one stool a day.
- What additional education regarding the lactulose and his liver disease does the nurse give to Mr. Parks?
