Ch. 47 Bowel Flashcards
The nurse is teaching a health class about the gastrointestinal tract. The nurse will explain that which portion of the digestive tract absorbs most of the nutrients?
a. Ileum
b. Cecum
c. Stomach
d. Duodenum
ANS: D
The duodenum and jejunum absorb most nutrients and electrolytes in the small intestine. The ileum absorbs certain vitamins, iron, and bile salts. Food is broken down in the stomach. The cecum is the beginning of the large intestine.
The nurse is caring for patients with ostomies. In which ostomy location will the nurse expect very liquid stool to be present?
a. Sigmoid
b. Transverse
c. Ascending
d. Descending
ANS: C
The path of digestion goes from the ascending, across the transverse, to the descending and finally passing into the sigmoid; therefore, the least formed stool (very liquid) would be in the ascending.
A nurse is teaching a patient about the large intestine in elimination. In which order will the nurse list the structures, starting with the first portion?
a. Cecum, ascending, transverse, descending, sigmoid, and rectum
b. Ascending, transverse, descending, sigmoid, rectum, and cecum
c. Cecum, sigmoid, ascending, transverse, descending, and rectum
d. Ascending, transverse, descending, rectum, sigmoid, and cecum
ANS: A
The large intestine is divided into the cecum, ascending colon, transverse colon, descending colon, sigmoid colon, and rectum. The large intestine is the primary organ of bowel elimination.
The nurse is planning care for a group of patients. Which task will the nurse assign to the nursing assistive personnel (NAP)?
a. Performing the first postoperative pouch change
b. Maintaining a nasogastric tube
c. Administering an enema
d. Digitally removing stool
ANS: C
The skill of administering an enema can be delegated to an NAP. The skill of inserting and maintaining a nasogastric (NG) tube cannot be delegated to an NAP. The nurse should do the first postoperative pouch change. Digitally removing stool cannot be delegated to nursing assistive personnel.
A nurse is assisting a patient in making dietary choices that promote healthy bowel elimination. Which menu option should the nurse recommend?
a. Broccoli and cheese soup with potato bread
b. Turkey and mashed potatoes with brown gravy
c. Grape and walnut chicken salad sandwich on whole wheat bread
d. Dinner salad topped with hard-boiled eggs, cheese, and fat-free dressing
ANS: C
Grapes and whole wheat bread are high fiber and should be chosen. Cheese, eggs, potato bread, and mashed potatoes do not contain as much fiber as whole wheat bread. A healthy diet for the bowel should include foods high in bulk-forming fiber. Whole grains, fresh fruit, and fresh vegetables are excellent sources. Foods without much fiber and with high levels of fat can slow down peristalsis, causing constipation.
A patient is using laxatives three times daily to lose weight. After stopping laxative use, the patient has difficulty with constipation and wonders if laxatives should be taken again. Which information will the nurse share with the patient?
a. Long-term laxative use causes the bowel to become less responsive to stimuli, and constipation may occur.
b. Laxatives can cause trauma to the intestinal lining and scarring may result, leading to decreased peristalsis.
c. Long-term use of emollient laxatives is effective for treatment of chronic constipation and may be useful in certain situations.
d. Laxatives cause the body to become malnourished, so when the patient begins eating again, the body absorbs all of the food, and no waste products are produced.
ANS: A
Teach patients about the potential harmful effects of overuse of laxatives, such as impaired bowel motility and decreased response to sensory stimulus. Make sure the patient understands that laxatives are not to be used long term for maintenance of bowel function. Increasing fluid and fiber intake can help with this problem. Laxatives do not cause scarring. Even if malnourished, the body will produce waste if any substance is consumed.
A patient with a hip fracture is having difficulty defecating into a bedpan while lying in bed. Which action by the nurse will assist the patient in having a successful bowel movement?
a. Preparing to administer a barium enema
b. Withholding narcotic pain medication
c. Administering laxatives to the patient
d. Raising the head of the bed
ANS: D
Lying in bed is an unnatural position; raising the head of the bed assists the patient into a more normal position that allows proper contraction of muscles for elimination. Laxatives would not give the patient control over bowel movements. A barium enema is a diagnostic test, not an intervention to promote defecation. Pain relief measures should be given; however, preventative action should be taken to prevent constipation.
Which patient is most at risk for increased peristalsis?
a. A 5-year-old child who ignores the urge to defecate owing to embarrassment
b. A 21-year-old female with three final examinations on the same day
c. A 40-year-old female with major depressive disorder
d. An 80-year-old male in an assisted-living environment
ANS: B
Stress can stimulate digestion and increase peristalsis, resulting in diarrhea; three finals on the same day is stressful. Ignoring the urge to defecate, depression, and age-related changes of the older adult (80-year-old man) are causes of constipation, which is from slowed peristalsis.
A patient expresses concerns over having black stool. The fecal occult test is negative. Which response by the nurse is most appropriate?
a. “This is probably a false negative; we should rerun the test.”
b. “You should schedule a colonoscopy as soon as possible.”
c. “Are you under a lot of stress?”
d. “Do you take iron supplements?”
ANS: D
Certain medications and supplements, such as iron, can alter the color of stool (black or tarry). Since the fecal occult test is negative, bleeding is not occurring. The fecal occult test takes three separate samples over a period of time and is a fairly reliable test. A colonoscopy is health prevention screening that should be done every 5 to 10 years; it is not the nurse’s initial priority. Stress alters GI motility and stool consistency, not color.
Which patient will the nurse assess most closely for an ileus?
a. A patient with a fecal impaction
b. A patient with chronic cathartic abuse
c. A patient with surgery for bowel disease and anesthesia
d. A patient with suppression of hydrochloric acid from medication
ANS: C
Any surgery that involves direct manipulation of the bowel temporarily stops peristalsis. Anesthesia can also cause cessation of peristalsis. This condition, called an ileus, usually lasts about 24 to 48 hours. Fecal impaction, cathartic abuse, and medication to suppress hydrochloric acid will have bowel sounds, but they may be hypoactive or hyperactive.
A patient has a fecal impaction. Which portion of the colon will the nurse assess?
a. Descending
b. Transverse
c. Ascending
d. Rectum
ANS: D
A fecal impaction is a collection of hardened feces wedged in the rectum that cannot be expelled. It results from unrelieved constipation. Feces at this point in the colon contain the least amount of moisture. Feces found in the ascending, transverse, and descending colon still consist mostly of liquid and do not form a hardened mass.
The nurse is managing bowel training for a patient. To which patient is the nurse most likely providing care?
a. A 25-year-old patient with diarrhea
b. A 30-year-old patient with Clostridium difficile
c. A 40-year-old patient with an ileostomy
d. A 70-year-old patient with stool incontinence
ANS: D
The patient with chronic constipation or fecal incontinence secondary to cognitive impairment may benefit from bowel training, also called habit training. An ileostomy, diarrhea, and C. difficile all relate to uncontrollable bowel movements, for which no method can be used to set up a schedule of elimination.
Which nursing intervention is most effective in promoting normal defecation for a patient who has muscle weakness in the legs?
a. Administer a soapsuds enema every 2 hours.
b. Use a mobility device to place the patient on a bedside commode.
c. Give the patient a pillow to brace against the abdomen while bearing down.
d. Elevate the head of the bed 20 degrees 60 minutes after breakfast while on bedpan.
ANS: B
The best way to promote normal defecation is to assist the patient into a posture that is as normal as possible for defecation. Using a mobility device promotes nurse and patient safety. Elevating the head of the bed is appropriate but is not the most effective; closer to 30 to 45 degrees is the proper position for the patient on a bedpan, and the patient is not on bed rest so a bedside commode is the best choice. Giving the patient a pillow may reduce discomfort, but this is not the best way to promote defecation. A soapsuds enema is indicated for a patient who needs assistance to stimulate peristalsis. It promotes non-natural defecation.
The nurse is devising a plan of care for a patient with the nursing diagnosis of Constipation related to opioid use. Which outcome will the nurse evaluate as successful for the patient to establish normal defecation?
a. The patient reports eliminating a soft, formed stool.
b. The patient has quit taking opioid pain medication.
c. The patient’s lower left quadrant is tender to the touch.
d. The nurse hears bowel sounds in all four quadrants.
ANS: A
The nurse’s goal is for the patient to take opioid medication and to have normal bowel elimination. Normal stools are soft and formed. Ceasing pain medication is not a desired outcome for the patient. Tenderness in the left lower quadrant indicates constipation and does not indicate success. Bowel sounds indicate that the bowels are moving; however, they are not an indication of defecation.
. The nurse is emptying an ileostomy pouch for a patient. Which assessment finding will the nurse report immediately?
a. Liquid consistency of stool
b. Presence of blood in the stool
c. Malodorous stool
d. Continuous output from the stoma
ANS: B
Blood in the stool indicates a problem, and the health care provider should be notified. All other options are expected findings for an ileostomy. The stool should be liquid, there should be an odor, and the output should be continuous.
The nurse will anticipate which diagnostic examination for a patient with black tarry stools?
a. Ultrasound
b. Barium enema
c. Endoscopy
d. Anorectal manometry
ANS: C
Black tarry stools are an indication of bleeding in the GI tract; endoscopy would allow visualization of the bleeding. No other option (ultrasound, barium enema, and anorectal manometry) would allow GI visualization.
