Give antidiarrheal drugs as ordered.
- Rationale: Most antidiarrheal drugs suppress gastrointestinal motility,
thus allowing for more fluid absorption. Supplements of beneficial
bacteria (“probiotics”) or yogurt may reduce symptoms by reestablishing
normal flora in the intestine.
Avoid the use of rectal Foley catheters.
- Rationale: Rectal Foley catheters can cause rectal necrosis, sphincter
damage, or rupture, and the nursing staff may not have the time to
properly follow the necessary and very time-consuming steps of their care.
Record number and consistency of stools per day; if desired, use a fecal
incontinence collector for accurate measurement of output.
- Rationale: Documentation of output provides a baseline and helps direct
replacement fluid therapy.
Evaluate dehydration by observing skin turgor over sternum and
inspecting for longitudinal furrows of the tongue. Watch for excessive
thirst, fever, dizziness, lightheadedness, palpitations, excessive cramping,
bloody stools, hypotension, and symptoms of shock.
- Rationale: Severe diarrhea can cause deficient fluid volume with extreme
weakness and cause death in the very young, the chronically ill, and the
elderly.
Monitor and record intake and output; note oliguria and dark,
concentrated urine. Measure specific gravity of urine if possible.
- Rationale: Dark, concentrated urine, along with a high specific gravity of
urine, is an indication of deficient fluid volume.
Provide perianal care after each bowel movement.
Cleanse with a mild cleansing agent (perineal skin cleanser).
Apply protective ointment prn.
If skin is still excoriated and desquamated, apply a wound hydrogel.
- Rationale: Mild cleansing of the perianal skin after each bowel movement
will prevent excoriation. Barrier creams can be used to protect the skin.

Instruct the patient to have Bulk fiber (e.g., cereal, grains, Metamucil)
- Rationale: Bulking agents and dietary fibers absorb fluid from the stool
and help thicken the stool.
Avoidance of stimulants (e.g., caffeine, carbonated beverages)
- Rationale: Stimulants may increase gastrointestinal motility and worsen
diarrhea.
