Fundamentals of Nursing - Flashcards
This article covers constipation, diarrhea, and different types of ostomies. You can follow along with our Fundamentals of Nursing flashcards, which are intended to help RN and PN nursing students study for nursing school exams, including the ATI, HESI, and NCLEX.
Constipation
Constipation occurs when bowel movements are difficult or infrequent and ongoing, lasting several weeks or longer.
It is important to treat patients who are constipated, as unresolved constipation can result in fecal impaction, which is when stool becomes stuck in the colon and can’t leave the body. This requires medical treatment.
What are the risk factors for constipation?
The risk factors for constipation include insufficient fluid and fiber intake, physical inactivity, and some medications. People of an older age are also at risk for constipation.
What are the signs and symptoms of constipation?
Signs and symptoms of constipation include decreased stool output or stool that is hard, dry, and possibly lumpy.
Difficulty passing stool is another indication that a patient may be constipated.
Patient teaching for constipation
Patients should increase their fluid intake, which will enter the bowel and soften the stool.
Patients should also increase the fiber in their diet. This promotes peristalsis.
They should also increase their physical activity — increased physical activity promotes peristalsis.
Diarrhea
What are the risk factors for diarrhea?
The risk factors for diarrhea include infections, some medications, food allergies or contamination, and GI dysfunction (e.g., celiac disease). Occasionally, diarrhea is a sign of another disorder, such as inflammatory bowel disease or irritable bowel syndrome.
What are the signs and symptoms of diarrhea?
Signs and symptoms of diarrhea include loose, watery, and possibly more-frequent bowel movements. Also: abdominal cramping and an urgency to defecate.
Diarrhea places the patient at an increased risk for dehydration, or fluid-volume deficit, as the patient is losing too much fluid in the stool. The signs and symptoms of dehydration include an increase in heart and respiratory rates, as well as dry mouth and fatigue. Diarrhea may also result in perineal skin breakdown or excoriation of the skin (lesions), which are caused by too much moisture in the perineal area (the genitals and rectum).
Patient teaching for diarrhea
Patient teaching for diarrhea focuses on resting the bowel. Patients should be advised not to eat anything they do not usually eat, and to avoid food this spicy or otherwise intense.
Patients should increase their fluid and fiber intake, and they should follow the BRAT diet: bananas, rice, applesauce, and toast.
Ostomies
An ostomy is a surgical procedure that reroutes part of the intestine through the abdominal wall, forming a stoma, that is, an opening in the body. Like a tracheostomy — an opening in the neck — an ostomy that relates to bowel elimination is a surgical opening that diverts the normal passage of the bowel.
Types of ostomy
There are two types of ostomy related to bowel elimination, ileostomy and colostomy.
Ileostomy
An ileostomy is created in the ileum of the small intestine.
The output from an ileostomy is loose and watery. This is because elimination occurs before fluid reaches the colon, where it condenses into stool. Output that does not flow all the way down to the colon, then, is watery.
Colostomy
A colostomy is created in the colon or the large intestine. This kind of ostomy may be situated in the ascending, transverse, or descending/sigmoid colon (the lower part of the colon), and the output will vary depending on which ostomy the patient has. The closer the ostomy is to the rectum, the more solid the stool.
- An ascending (right) colostomy results in liquid or watery stool
- A transverse colostomy results in semi-solid stool
- A descending/sigmoid (left) colostomy results in more solid, formed stool
Ostomy nursing care and patient teaching
Patients with ostomies need to take care of their stoma and know the timing and procedures for bag/appliance changes.
Assess the stoma regularly
The stoma (the opening in the skin) should be checked regularly. A normal looking stoma is pink or red and moist. This indicates a good blood supply.
Report a stoma that appears pale or blue immediately to the provider as this could indicate an ischemia (a condition in which the blood flow, and thus oxygen, is restricted or reduced in a part of the body). The patient requires emergency surgery.
When to empty an ostomy bag
Output from the bowel (or intestine or colon) is collected in an ostomy bag. Empty the ostomy bag when it is one-third full.
If the appliance is leaking, change it immediately.
How to “cut the wafer”
The wafer is the part of the device that sticks to the patient’s skin. Patients should learn to measure their stoma. Usually, there is a template card for this purpose. The patient places the template card over the stoma to see which template fits it best. Then, they cut the opening less than or equal to an eighth of an inch wider in diameter. This is to prevent skin damage from contact with any ostomy output, as moisture could lead to skin damage.
Also, it is important to cut the correct size so the device is not too tight, which can lead to ischemia.
How often should the patient change an ostomy appliance
The ostomy appliance should be changed approximately every two weeks for a patient with a colostomy and more frequently for a patient with an ileostomy.
Chew foods thoroughly
Chewing foods thoroughly will make the output easier.
Patients should consume a low-fiber diet for the first 6 – 8 weeks and avoid foods that cause gas or odor.
An important note about nursing care for patients with ostomies
A patient with an ostomy must learn how to take care of themselves from scratch. In addition, a patient dealing with an ostomy bag may find it disorienting or confusing, and this change in their life could have a psychosocial impact as well.
As a wound care or ostomy care nurse, patient care is paramount. Help comfort the patient prior to surgery. Help them identify the best location for their ostomy. Post-surgery, help them connect with resources in their community so they can learn how to care for themselves and how to care for their stoma.
Being a trusted, sympathetic resource for this patient can make a huge difference as they navigate this new situation they find themselves in.
