Answer:
Option C, increase intake of fluids
Explanation:
Many laxatives recruit water in order to soften stool and improve mobility of feces through the large intestines, as is the case with a laxative medication like docusate sodium (brand name Colace). Because of this, the nurse and the healthcare staff will want to ensure the patient is adequately replenishing these fluid losses in order to avoid dehydration, hypernatremia due to change in sodium concentration, and any other resulting electrolyte imbalances.
Laxatives are not expected to produce any abdominal pain or nausea and vomiting, though they do list diarrhea, abdominal cramping, and bloating as potential side effects. Potential changes to vital signs may occur with insufficient fluid replacement, which is why increased fluids is the initial priority.
Therefore, it is the nurse's responsibility to increase the patient's intake of fluids, option C.
