Gastrointestinal System


 

 





LEARNING OUTCOMES






 


Upon completion of this chapter, the nurse will:



1.  Outline the areas to include when assessing the gastrointestinal system


2.  Identify appropriate questions to assess the gastrointestinal system


3.  Analyze approaches to gather more information about the gastrointestinal system


THE GASTROINTESTINAL SYSTEM


The primary function of the gastrointestinal system is digestion. The organs and structures within the system are extensive and include:



  Mouth


  Esophagus


  Stomach


  Small intestine


      Duodenum


      Jejunum


      Ileum


  Large intestine


      Cecum


      Ascending colon


      Transverse colon


      Descending colon


      Sigmoid colon


      Rectum


      Anus


The organs of digestion need assistance for food to be absorbed and utilized by the body. These accessory organs include:



  Liver


  Gallbladder


  Pancreas


As a review, after swallowing food that is chewed in the mouth, it travels through the esophagus to the stomach where it begins to be broken down and converted into a substance called chyme. Once chyme enters the small intestine, it is further broken down by enzymes secreted by the liver, gallbladder, and pancreas in preparation for being absorbed. Once all potential substances are absorbed, the residue from the food is advanced to the beginning of the large intestine where any additional water from the food residue is absorbed. At the completion of this entire process, the remnants of ingested food are eliminated in the stool.


Although this process sounds easy, many things impact a well-functioning gastrointestinal system. First of all, a person needs to have an appetite in order to seek food. Then, adequate dentition and sufficient saliva are needed to wet the food and begin the breaking down process. The esophagus needs to be intact with a functioning cardiac sphincter to prevent food from backing up from the stomach. The stomach needs to have sufficient hydrochloric acid to prepare chyme and an intact pyloric sphincter to prevent reflux of chyme once it advances into the small intestine. The liver, gallbladder, and pancreas need to be functioning at a high level in order to break down proteins, carbohydrates, and fats for body absorption. And the large intestine needs to be clear and free of inflammation in order to adequately remove food residue from the body.


ASSESSMENT OVERVIEW


Because the gastrointestinal system involves many parts and body organs, it is best to approach the assessment methodically. As with other body organs, the traditional methods to assess this system telephonically are different. You will need to focus on thoughtful questioning and careful listening when completing the assessment of this body system.


Keep in mind that you will not be able to:



  Inspect the condition of the oral cavity including dentition


  Auscultate bowel sounds


  Palpate the abdomen


  Percuss the abdomen


  Observe the color of emesis or stool


  Test stool for occult blood


  Further assess stool for steatorrhea


  Observe skin color for jaundice


Because the organs within this system are grouped as primary and accessory, assessment can occur following the same approach. Remember that most people do not like to spend time discussing their digestion and bowel function. For some, this can be uncomfortable, and a patient/client may provide short answers without divulging what they consider intimate information. A “matter of fact” conversational approach is recommended to gather the most quality information.


QUESTIONS TO ASSESS THE GASTROINTESTINAL SYSTEM


As with other system assessments, begin by asking if the patient has had any problems with eating or digesting food. If the answer is “no,” you can conduct a general assessment of all major gastrointestinal organs. You can begin the assessment of this system by introducing the questioning with a general statement such as:



  “I’m glad to hear that you don’t have any issues with eating or digestion. Let’s just take a few minutes anyway and go over some specific areas.”


Some seasoned telephonic nurses like to begin the assessment of the gastrointestinal system by asking the patient for his or her height and current weight. From this information, the nurse then proceeds into the general questions. This approach is appropriate for some patients but not for others. Use your best judgment. There is no “right or wrong” time to gather height/weight information.

SPECIAL SITUATION


The frequency of patients having bariatric surgery for obesity has been consistent. At times, a patient will be referred to telephonic care before/after the surgery to provide ongoing education and support. Should you have a patient who is recovering from bariatric surgery, the following assessment questions might be beneficial.


 

















































Before surgery


Would you happen to know your body mass index (BMI)? Or what is your current weight?


 


When are you scheduled for the surgery?


 


What type of surgery are you going to have?


 


What have you been told about the surgery?

Have you been back to see the doctor after the surgery?


 


How successful has it been so far? Such as:


  How much of a weight loss have you experienced?


 


Are you having any problems from the surgery?


 


How much food would you say you are currently able to eat?


 


Are there any foods that you are unable to eat?


 


When are you scheduled to see your doctor/health care provider again?


ALGORITHM FOR ASSESSING THE GASTROINTESTINAL SYSTEM


Similar to other body system assessments, this one is quite lengthy too. If you prefer, you can change the approach and just focus on problem areas. Questions to support this are as follows:


 






























































































































































































Finding


Action

  Black like coffee grounds


  Blood


 


Assess for abdominal pain with the nausea and vomiting.


 


Suspect gastrointestinal flu or food poisoning if associated with eating and encourage seeking medical attention.


 


Suspect gastrointestinal bleeding if emesis is red or black and coffee ground in appearance. (Emesis green in color is bile and not associated with any particular health problem.)

Suspect gastrointestinal infection for unexplained onset of diarrhea and encourage to seek medical attention.


Constipation


Assess for last bowel movement.


 


Assess for routine bowel movement pattern.


 


Assess appearance of stool.


 


Assess for any leaking of stool or liquid stool. (Leaking of liquid stool could indicate an impaction.)


 


Assess for changes in diet, fluid intake, or activity to contribute to the development of constipation.


 


Assess if prescribed opioid analgesics. If so,


  The name of the medication


  Length of time taking the medication



Assess what has been done to self-treat the constipation and if it has been effective.

Assess how long the color has been present.


 


Assess if the skin is itchy or any other symptoms.


 


Assess for a change in the color of bowel movements.


 


Assess if associated with:

TIPS FOR ASSESSING THE GASTROINTESTINAL SYSTEM


  Remember that this is a body system that many people do not like to discuss. Emphasize that all information will be kept confidential.


  Do not assume that older clients’ problems with this system are all age related. Normal age-related changes of the gastrointestinal system include change in smell and taste, slower gastric emptying, and slower propulsion of food through the small bowel and colon.


  Ask if the client has made any dietary changes that could have caused the current issue.


  Find out how much water/fluid is ingested every day. Oftentimes an older client may adjust oral fluid intake to prevent nighttime voiding. This could be a reason for a new onset of constipation.


  Diligently assess if the client reports red or coffee-ground emesis or black stools. This could indicate an active or ongoing bleed somewhere throughout the gastrointestinal tract that needs to be thoroughly investigated.


  Be sure to include asking if the client has any pain that might not seem to be related to the stomach or bowels such as shoulder pain caused by gallbladder disease.


  When asking about weight, find out if the patient has had any changes (gains or losses) that would not be associated with oral intake. If a weight loss is reported, find out if it has been intentional. The patient/client may be following a restricted eating plan with the desired effect of weight loss.
