A male patient has told a nurse that he occasionally fights constipation. Teaching the patient how to prevent constipation and promote normal elimination, the nurse instructs him to
A. Take a stool softener or laxative every day until a normal elimination pattern has been reestablished.
B. Eat small amounts at meals so less waste will need to be expelled.
C. Eat a minimum of 50 g fiber every day and quickly increase the amount until normal defecation becomes routine.
D. Drink at least 2000 ml fluid every day, but limit the amount of caffeine to 300 mg
