Bowel Elimination Chapter 28 Flashcards
What are the major functions of the small intestine and large intestine?
Answer:
The intestine has the following major functions:
● Small intestine. The major function of the small intestine is the digestion and absorption of carbohydrates, fat, and protein.
● Large intestine. The major function of the large intestine is the absorption of water, vitamins, and minerals.
How do the rectum and anus control elimination of feces from the body?
Answer:
Normally, the rectum is free of waste products until just before defecation. Feces and flatus (gas) are expelled from the rectum through the anus. The anus has two ringlike muscles that function as sphincters. The internal sphincter relaxes and opens when feces is present in the rectum. This is an involuntary reaction. The external sphincter is under voluntary control. Relaxation of the external sphincter allows feces, or stool, to be expelled from the body.
What is a normal defecation pattern?
Answer:
There is a wide range of “normal.” The frequency of BMs may range from several times per day to once per week. Bowel function may be regarded as normal as long as stools are passed without excessive urgency (needing to rush to the toilet), with minimal effort and no straining, without blood loss, and without the use of laxatives.
Identify the factors that affect bowel elimination.
Answer:
The following factors affect bowel elimination:
● Age
● Stress
● Dietary intake
● Fluid intake
● Activity
● Medications
● Surgery
● Anesthesia
● Pregnancy
● Pathological conditions (e.g., food allergies and intolerances, diverticulosis, diverticulitis)
What changes in bowel elimination are associated with constipation? With diarrhea?
Answer:
The following changes in bowel elimination are associated with these conditions:
● Constipation is a decrease in frequency of BMs. As the length of time between BMs increases, more water is reabsorbed from the feces. As a result, constipation is also associated with passage of dry, hard stool that requires more effort to pass.
● Diarrhea is an increase in the frequency of BMs. As transit time through the colon decreases, less water is reabsorbed and stools are often watery.
Why are bowel diversions performed?
Answer:
A bowel diversion is a surgically created opening for elimination of digestive waste products from the bowel. This procedure is performed for clients with a variety of conditions, including cancer, ulcerations, trauma, or inadequate blood supply. Temporary diversions are performed to allow healing of the distal portion of the bowel; permanent diversions are performed in instances of severe disease or trauma when the bowel is necrotic or cannot be salvaged.
What determines the nature of the effluent from a bowel diversion?
The effluent may range from liquid to solid depending on the part of the bowel that is being diverted. The lower in the bowel the colostomy is placed (i.e., the closer to the rectum and anus), the more solid the effluent. Because the fecal matter stays in the bowel longer, more water can be absorbed from it, and it becomes more solid.
What should you discuss with your client when performing a nursing history focused on bowel elimination?
Answer:
The following items should be part of a nursing history focused on bowel elimination:
● Normal bowel pattern
● Appearance of stool
● Changes in bowel habits or stool appearance
● History of elimination problems
● Use of bowel elimination aids, including diet, exercise, medications, and remedies
Describe the physical assessment you would perform for a client with constipation.
Answer:
Physical assessment for bowel elimination includes examination of the abdomen, rectum, and anus.
● Recall that in abdominal assessment, the order of the exam is inspection, auscultation, percussion, and palpation.
● Observe the size, shape, and contour of the abdomen, and listen to bowel sounds.
● Percuss and palpate the abdomen for tenderness, presence of air or solid, and presence of masses.
● Inspect the anus for signs of hemorrhoids.
● Depending on the policies of your institution as well as your skill with assessment, you might also palpate the anus and rectum for the presence of stool or masses.
Identify at least five independent nursing actions that you could take to encourage regular elimination in a well client.
Answer:
The following nursing actions encourage regular elimination in a well client:
● Provide privacy when using the bathroom
● Allow for uninterrupted time to defecate, especially after meals
● Teach the client to do the following:
● Assume a seated or squatting position when attempting to have a BM
● Drink at least 1,500 mL (preferably 8 to 10 glasses, or 2,000 to 2,400 mL) of fluid per day
● Exercise 3 to 5 times per week
Identify the types of enemas available for use.
Answer:
Enemas may be classified as follows:
● Cleansing
● Retention
● Return-flow (Harris flush)
How do hypotonic and isotonic enemas differ from hypertonic enemas?
Answer:
The enemas have the following differences:
● Hypotonic and isotonic enemas are large-volume enemas. The volume causes intestinal distention and leads to rapid evacuation of stool.
● Hypertonic enemas are usually smaller volume (2.5–4 ounces or 70–120 mL). The hypertonic solution attracts water into the colon, causing distention and stimulating peristalsis and defecation. Patients are usually able to retain hypotonic and isotonic longer than hypertonic solutions. Hypertonic solutions are more irritating to the mucosa.
What actions can you take to make the patient more comfortable when he receives an enema?
Answer:
The following actions make the patient more comfortable when receiving an enema:
● Explain the purpose of the enema and what the patient can expect.
● Always provide privacy when administering an enema.
● Reassure the patient that you will be immediately available to help the patient to the restroom or onto the bedpan.
● Lubricate the tip of the enema and administer the solution slowly.
● Have the patient breathe slowly through the mouth.
What are the major patient care concerns associated with bowel incontinence?
Answer:
Major concerns associated with bowel incontinence include patient embarrassment, anxiety, social isolation, and lowered self-concept. In addition, clients with bowel incontinence are at risk for skin breakdown.
What are the elements of a bowel training program?
Answer:
A bowel training program includes the following elements:
● Planning the program with the patient and caregiver
● Gradually increasing fluid, fiber, and activity to promote regular bowel movements
● Initiating a designated uninterrupted time, in private, to defecate
● Developing a staged treatment plan when constipation develops
● Regularly modifying the plan based on the patient’s response
