How is diarrhea defined in terms of stool frequency? - ANSWER-At least 3 loose or liquid stools
a day.

electrolyte shock.
What diagnostics are used to identify the cause of diarrhea? - ANSWER-Stool specimen
analysis, CBC, CMP, ABGs.
What nursing assessments should be performed for a patient with diarrhea? - ANSWER-Health
history and physical assessment, stool assessment, food intake, medications, and assessment for
dehydration and infection.
What are the nursing interventions for managing diarrhea? - ANSWER-Oral or IV
fluids/electrolyte replacement, administering antidiarrheal medications or antibiotics with
caution.
, Why should antidiarrheal medications be administered with caution? - ANSWER-To prevent
masking underlying infections and complications.
What is C. Diff and its significance in lower GI disorders? - ANSWER-Clostridium Difficile is a
hazardous bacterial infection that causes severe diarrhea and is highly infectious.

than 14 days, while chronic diarrhea lasts more than 30 days.
What is the role of stool specimens in diagnosing lower GI disorders? - ANSWER-To check for
blood, mucus, WBCs, culture, O & P, and C. Diff.
What is the primary etiology of constipation? - ANSWER-Slowed GI motility.
What are some common causes of constipation? - ANSWER-Medications, poor oral fluid and
fiber intake, lack of physical activity, ignoring the urge to defecate, anxiety, stress, depression,
certain diseases, and chronic laxative use.
What are the clinical manifestations of constipation? - ANSWER-Hard, dry infrequent stools that
are difficult to pass, abdominal discomfort, distention, bloating, gas pains, rectal pressure, and
