Chapter 24
Diabetic patients: An abnormally low blood glucose level.
Hypoglycemia
Nursing Responsibilities:
Monitor diet type, percentage eaten, and whether the meal was tolerated. ●Determine when to advance the patient's diet.
There are two types of parenteral nutrition:
PPN & TPN
Enteral Feeding Methods: a type of intermittent tube feeding that is frequently used, in which a health-care provider-ordered volume of formula is administered at set intervals throughout the day. To administer a large irrigating syringe (50 mL or greater) is attached to the feeding tube.
Bolus feedings
a type of intermittent tube feeding that is frequently used, in which a health-care provider-ordered volume of formula is administered at set intervals throughout the day.
Bolus feedings
Commonly referred to as binge eating, this eating disorder is accompanied by behavior to get rid of some of the calories that were ingested while bingeing, such as self- or medication-induced vomiting (known as purging), excessive exercise, fasting, or the overuse of laxatives.
Bulimia nervosa
Used for those patients who must lose weight.
Calorie restricted diet
Nutrition that uses the GI tract as a delivery system and that involves tube feedings that usually replace all oral intake but may also be given as a supplement to oral ingestion of nutrients.
Enteral nutrition
Used during the acute phase of intestinal disorders when the presence of fiber may exacerbate intestinal pain, produce diarrhea, or cause an intestinal blockage. This diet is often used before intestinal surgery to minimize fecal volume or after surgery to allow the GI system to transition gradually to a regular diet.
Fiber restricted
People with celiac disease must be on a gluten-free diet. However, other people may have a condition known as "nonceliac gluten sensitivity" and also need to avoid gluten. Still others may have a wheat allergy that requires them to avoid gluten-containing foods. Celiac disease is an autoimmune condition, and wheat allergy causes histamine release. Nonceliac gluten sensitivity is not an autoimmune response but has similar symptoms. Often the diagnosis is made if removing gluten from the diet causes symptoms to subside. Gluten is found in wheat, rice, and maize. It is present in foods like barley, flour, couscous, tabouli, and malt vinegar. Sometimes certain meat products and even some pharmaceuticals may contain gluten.
Gluten free diet
Diabetic patients: An abnormally elevated blood glucose level.
Hyperglycemia
A diet that consists of all the liquids found in a clear liquid diet with the addition of all other opaque liquids and food items that become liquid at room temperature.
full liquid diet
Diets that may be modified by preference include:
gluten-free and vegan.
A long-term feeding tube inserted into the jejunum.
jejunostomy tube, or J-tube.
This diet includes all of the items from the full liquid diet plus the addition of foods such as scrambled eggs and cottage cheese. Many items can be included in this diet by altering their texture through extensive cooking or use of a blender or food processor.
mechanical soft diet
A long-term feeding tube inserted into the stomach through the skin and abdominal wall.
percutaneous endoscopic gastrostomy tube (PEG tube)
Complications can arise with enteral tube feeding, such as:
clogged tubes, aspiration, electrolyte imbalance, hyperglycemia, and severe diarrhea.

An eating disorder marked by relentless self-starvation in an effort to reduce the body weight below normal. This disorder is characterized by an excessive leanness or wasting of the body, known as emaciation.
Anorexia nervosa
Used to manage calorie and carbohydrate intake for patients with diabetes mellitus, primarily those who are insulin dependent.
Diabetic diet
Used for patients who are experiencing problems with fat malabsorption, such as those with disorders affecting the gallbladder, liver, lymphatic system, pancreas, or intestines. It also may be used for those patients who have elevated triglyceride, lipid, or cholesterol levels, as well as for patients who need general weight loss.
Fat restricted diet
A health-care provider may order any type of diet to be provided in several smaller feedings throughout the day rather than the traditional three meals per day. This is used with those patients who have difficulty tolerating larger meals or who simply are unable to eat more than a few bites at a time, as well as those who need to have food gradually reintroduced. Often elderly patients are only able to eat small amounts at a time. This makes it difficult for them to obtain the needed nutrients in the traditional three meals per day. By increasing the number of meal or snack times from three to five or six per day, the patient has a better chance of receiving the needed nutrients.
Five to six small, frequent feedings diet
a reaction by the patient's immune system to an allergen, which is a food protein that, once ingested, causes the immune system to develop antibodies.
Food allergy
An adverse, nonallergic reaction to a food without activation of the immune response.
Food intolerance
an adverse reaction to a food without activation of the immune response.
Food intolerance
When educating a diabetic patient about simple carbohydrates, the nurse teaches that simple carbohydrates are quickly converted to glucose and can be used to quickly raise the blood glucose. The nurse identifies an example of a simple carbohydrate as
Fruit juices
the process of reducing the pressure within the stomach by emptying it of its contents. An NG tube is inserted into the stomach and connected to low intermittent suction to accomplish this.
Gastric decompression
Used to increase calorie and protein intake in those patients with increased need related to wound healing, growth promotion, and increasing or maintaining weight. High-fat foods also may be added to increase calories available for energy use
High calorie, high protein
Dietary effects that reduce medication absorption typically occur through the influence of increased gastric motility, conditions within the GI tract that are either too acidic or too alkaline, or direct interaction of food with a medication.
Important information
Excretion refers to the process of eliminating a medication or its metabolites or nutritional components from the body, a function usually performed by the kidneys. The length of time it takes to excrete a medication influences the extent of the medication's therapeutic effects. Slowed or inadequate excretion can raise the blood level of a medication and cause toxicity as successive scheduled doses are administered. Rapid or increased excretion can limit or greatly reduce the medication's therapeutic effect.
Important information
Metabolism of food and medications occurs through the use of enzyme systems in the small intestine and liver. Some medications can inhibit or induce the activities of these enzyme systems, impairing the metabolism of nutrients. For example, the anticonvulsant phenytoin induces the liver system that metabolizes folate, vitamin D, and vitamin K. Patients taking this anticonvulsant will need additional supplements of these vitamins.
Important information
NG and NI tubes inserted for instillation of nutritional feedings are generally softer and smaller than those used for gastric decompression or lavage.; however, they tend to go down easier because they are smaller and softer.
Important information
The side effects of medication, such as nausea, vomiting, altered taste sensation, anorexia, decreased salivation, and sores or lesions in the mouth or the upper GI tract, can inhibit appetite or make food intake painful. Some medications can be very sedating or cause the patient to feel confused; this in turn will interfere with nutritional intake.
Important information
Certain medications can alter the absorption, metabolism, or excretion of nutrients. Alternatively, some nutrients can alter the absorption, metabolism, or excretion of medications.
Information
Check placement of a feeding tube: If the placement of a tube is not confirmed prior to administering a feeding or medication, there is a risk of instilling the formula or medication directly into the lungs via an NG tube or into the sterile peritoneal cavity via a PEG tube or J-tube.
Information
Checking Residual Gastric Volume: Before you can safely administer a tube feeding, not only must you check tube placement but you also must assess the residual gastric volume, or the amount of formula that still remains in the stomach from the previous feeding. Safety: It is vital that you check the residual volume as well as tube placement before instilling each tube feeding.
Information
Continuous Infusion Feedings: Continuous feedings are best administered via an infusion pump at a constant rate over an 8- to 24-hour period. The continuous infusion method promotes better tolerance of feedings and nutrient absorption. Use of the pump provides greater control of the rate and amount of feeding delivered. This method is used with critically ill patients because of the decrease in hypermetabolic response to stress, the risk for aspiration, and the incidence of diarrhea. Continuous feedings should be interrupted every 4 hours to check placement and residual volume, to administer water for hydration if ordered, and to flush the tube to prevent clogging. Safety: These patients must have the head of the bed raised at least 30 degrees continually to reduce the risk of aspiration.
Information
Food intolerance can stem from the body's lack of digestive enzymes or an inability to utilize these enzymes. The resultant symptoms of intolerance are usually of a GI nature, such as bloating, flatulence, diarrhea, or nausea. Treatment of food intolerances requires identification of the offending agent; this can be accomplished by eliminating various foods from the diet over a period of time.
Information
It is important to carefully measure and record all fluids taken in as intake, whether they are taken in by mouth, are given via IV, or are administered as enteral or parenteral fluids. It is also important to measure and record all bodily fluids that are lost as output, including urine, emesis, liquid stool, blood, gastric contents, and drainage. These measures give valuable information about the patient's fluid balance.
Information
Methods for assisting with meals for patients in the hospital include preparing the environment and preparing the patient, as well as assisting the patient with eating, if needed.
Information
NG tubes are shorter than NI tubes because they go only to the stomach. NI tubes are usually smaller in diameter and more flexible than NG tubes. The double lumen tube, also called a Salem sump, is used strictly for gastric decompression.
Information
Nurses are responsible for monitoring the type of diet, percentage eaten, and whether or not the patient tolerated the meal. They are also responsible for advancing the patient's diet when "Advance as tolerated" is ordered. Diabetic patients have many special needs, and the nurse is responsible for teaching as well as assessing the patient for complications such as hypoglycemia and hyperglycemia.
Information
Other food-drug interactions can create medication toxicity.
Information
PPN solutions contain a lower concentration of dextrose than TPN. When administering any type of parenteral nutrition, the nurse must adhere strictly to sterile technique; contamination can lead to serious infection and septicemia.
Information
Patients requiring long-term feedings have surgical endoscopic placement of a percutaneous feeding tube. Percutaneous means that an incision is made through the skin and abdominal wall, allowing the tube to extend from either the stomach or the jejunum to the external surface of the abdomen.
Information
Patients with difficulties tolerating oral intake may receive enteral feedings. Tube feedings can be NG or NI or via the lower GI tract via a PEG tube or J-tube.
Information
Small-bore feeding tubes now require the use of ENFit tubes, bags with tubing, and syringes. These will only connect to one another and will not connect to IV tubing to prevent misconnection errors.
Information
Some drugs can affect appetite or digestion due to side effects. Some drugs can alter the absorption, metabolism, and excretion of nutrients by affecting GI and liver function. Some drugs affect the kidneys and interfere with the excretion of nutrients.
Information
Some medications can affect nutrient intake by inhibiting appetite, causing GI discomfort, or by causing some other reaction that inhibits food intake by making it unpleasant or painful. Other medications can stimulate appetite, increasing the quantity of food ingested.
Information
Tube feedings can be continuous or intermittent bolus. Continuous feedings should be administered with a feeding pump.
Information
Verification of NG/NI tube placement by radiography is the most accurate method. Aspiration of gastric contents and assessment of the pH are used to verify continued presence of the tube in the proper location of the GI tract.
Information
The physician writes an order to discontinue a nasogastric (NG) tube. When discontinuing the NG tube, the nurse should
Instill 10 to 20 mL of air into the NG tube's main lumen.
The physician writes an order for the nurse to insert a nasogastric (NG) tube for gastric decompression. When inserting the NG tube, the nurse should
Instruct the patient to hyperextend his or her head slightly and then gently insert the tube into the intended naris
The nurse is caring for a patient who is receiving formula through intermittent tube feedings. When caring for this patient, the nurse should
Maintain the formula at room temperature
____status means nothing by mouth and is usually ordered for a limited time as preparation for procedures or tests.
NPO
ENTERAL TUBES: Shorter •Inserted through nose and into stomach •Single lumen versus double lumen
Nasogastric tube
ENTERAL TUBES: •Longer •Inserted through nose, through stomach, into duodenum •Smaller in bore size •More flexible
Nasointestinal tube
Diets that are modified by consistency include:
clear liquid, full liquid, mechanical soft, and pureed.
The following are the most common food allergies:
Peanuts Wheat Dairy products Eggs
Used to manage protein intake for those patients with liver or kidney disease.
Protein restricted diet
_____diets are ordered for patients without special nutritional needs.
Regular
Used to manage or limit fluids and electrolytes for patients with renal insufficiency or disease. The renal diet is complex, and the patient's nutritional needs change over the course of the disease. A dietitian specializing in renal disorders may guide the nutritional therapy.
Renal diet
Used for those patients with hypertension, congestive heart failure, or kidney or liver failure, as well as those who require help to prevent or correct fluid retention. The degree of restriction is commensurate with disease severity, severity of symptoms, and the medication regimen prescribed. Typically sodium restrictions range from 2,000 to 3,000 mg per day. While many patients think that simply not adding salt to foods provides adequate sodium restriction, this is not actually the case. Most of the sodium that people ingest comes from processed foods, making it necessary to read labels for sodium content if the patient is sent home on this diet.
Sodium restricted diet
People may choose to be vegan for a number of reasons. Some feel it is better for the environment, some feel that animals should not be food sources for people, and others may decide it is a healthier choice for them personally. Some studies have shown that eating a vegan diet has improved or reversed some diseases, particularly cardiovascular diseases. Those on a vegan diet eat plant-based only. They avoid all meat, including fish and poultry, and any other animal products or by-products. They do not consume eggs, dairy products, or honey. This diet is rich in fruits and vegetables, leafy greens, whole grains, nuts, seeds, legumes, and tofu (soy).
Vegan diet
Common eating disorders include:
anorexia nervosa, bulimia nervosa, and binge eating disorder.
A third type of eating disorder is characterized by episodes of eating large quantities of food at one time, with a loss of control while eating. The person with disorder may eat very quickly and be to a point of discomfort but continue to eat. This disorder is the most common eating disorder in the United States.
binge eating
A type of diet ordered to provide hydration and calories in the form of simple carbohydrates that help meet some of the body's energy needs; most often used postoperatively or during recovery from gastrointestinal disease such as vomiting and diarrhea, when the gut must be introduced slowly to food. Examples of clear liquids include water, broth, and tea without milk.
clear liquid diet
Some common diets modified for disease are:
diabetic, sodium-restricted, fat-restricted, and renal diets.
