73. List the steps of determining the nutrition prescription.​

ANSWER:   ​To determine the nutrition prescription, the clinician must first calculate the patient’s dosing weight, as well as protein, energy, and fluid requirements. The clinician then identifies the most appropriate type of formula based on the patient’s diagnosis. Total energy needs are calculated and then divided by the caloric density of the formula. To determine the goal rate of administration, the clinician divides the total formula volume by the number of hours administered. The starting rate may be lower and then the rate advanced as tolerated to reach the goal rate.

Box 5.3 summarizes the protocol for the insertion of tubes in adults. (See the “Equipment” section later in the chapter for more information about the tubes and other supplies involved.)

77. ​Describe indications, advantages, and disadvantages of the following types of enteral feeding tubes: nasogastric tubes, orogastric tubes, gastrostomy tubes, PEG tubes.

ANSWER:   ​Nasogastric tubes are indicated in cases of normal GI function; they stimulate digestive function, are easy to insert and maintain, and they allow for medication administration. Disadvantages of nasogastric tubes include patient discomfort, increased risk of aspiration, irritation of the nasal passages, and the potential for tube displacement. Orogastric tubes are used with normal GI function but when a nasogastric tube is not feasible. Advantages include normal stimulation of gut function, they are easy to insert and maintain, and medications can be placed in the tube. Disadvantages include tube displacement, increased risk of aspiration, and discomfort for the patient. Gastrostomy and PEG tubes bypass the upper GI tract and are used for long-term feedings. Gastrostomy tubes allow for boluses, they are used long term, and there is less risk of aspiration or tube displacement, but they require surgery for placement and the patient can develop skin irritation at the insertion site. PEG tubes can be inserted on an outpatient basis, they allow for bolus feedings, and there is little risk of tube displacement but there is a greater risk of skin irritation at the insertion site.

78. ​List and describe four examples of complications associated with enteral feedings.

ANSWER:   ​Enteral feeding is not a simple procedure. Patients who receive enteral feedings may experience a variety of complications, and some of these—such as aspiration or tube misplacement—are serious. Complications of enteral feedings may develop at any point during a course of therapy. High-risk patients who have concurrent illnesses require an experienced dietitian to successfully manage enteral feedings.

79. ​Explain indications for using parenteral nutrition and list several conditions that would require parenteral nutrition instead of enteral nutrition.

ANSWER:   ​Parenteral nutrition is indicated in those clinical situations where the patient is unable to meet nutritional needs either by an oral diet or through the use of enteral nutrition. The clinical conditions that may require parenteral nutrition include an inability to digest and absorb nutrients, such as in massive bowel resection or short bowel syndrome; intractable vomiting, as in hyperemesis gravidarum; GI tract obstruction;impaired GI motility; and abdominal trauma, injury, or infection. Nutrition diagnoses associated with candidates for PN are the same as those for EN.

80. ​Describe the use of a pharmacy compounder with the nutrition prescription and list advantages as well as disadvantages.

ANSWER:   ​Automated compounders can be used to manufacture nutrient solutions that combine dextrose and amino acids (two-in-one formulas) or dextrose, amino acids, and lipids (three-in-one formulas). PN can be provided in either a two-in-one or three-in-one system, and each system has both advantages and disadvantages. In the two-in-one, lipids are added separately based on the available container sizes (100 mL, 250 mL, or 500 mL). This system provides a greater degree of flexibility in the amounts of dextrose and amino acids that can be given. A disadvantage of the two-in-one system is the need for an additional administration set (intravenous tubing and other devices required for the delivery of parenteral nutrition) for the lipids. The three-in-one system requires a single administration set, which saves nursing time and reduces costs. On the other hand, the addition of lipids with the three-in-one system results in an opaque solution, which obscures precipitate and increases the risk of particulate being infused into the patient. Addition of lipid into the three-in-one solution limits the electrolytes and final concentration of amino acids in solution.
