NURA 1110 Exam 4 Nutrition

To determine the distance the NGT:

must be inserted to reach the stomach, measure from the *tip of the nose* to the *ear lobe* and from the *tip of the ear* to the *xiphoid* process.

NGT placed for *Gavage*

(getting) getting something via a NGT. EX: A patient who is malnourished may receive a NGT for feeding.

NGT placed for *Lavage*:

(leaving) removing content from the stomach. EX: Patient consumes toxic substances placement is use for removing it.

A nurse is preparing a presentation about basic nutrients for a group of high school athletes. She should explain that which of the following nutrients provide the body with the most energy?

Carbohydrates Carbohydrates are the body's greatest energy source; providing energy for cells is their primary function. They provide glucose, which burns completely and efficiently without end products to excrete. They are also a ready source energy, and they spare proteins from depletion.

2. A nurse is planning a high-energy diet for a patient. What nutrient provides energy to the body and should be increased in the diet? a. Carbohydrates b. Vitamins c. Minerals d. Water

a Carbohydrates

Nasogastric Tube (NGT) Placement and Care: What is it?

Short-Term Nutritional Support used for (less than 4 weeks) - Its a tube inserted through the nose and into the stomach. *Contraindications*: Pt's with: - Dysfunctional gag reflex - High risk of aspiration - Gastric stasis - Gastroesophageal reflux - Nasal injuries - Pt's that are unable to have the head of the bed elevated during feedings.

Pre-administration assessments for diuretics:

- depend upon the reason for administering the diuretic but should include at a minimum: VS and K+ level, urinary output, lung sounds, & edema. - Increases the potential for hypotension when given with anti-hypertensives.

Common diuretics

- furosemide (Lasix) - hydrochlorothiazide (HCTZ) - spironoloactone (Aldactone) - potassium sparing - bumetanide (Bumex) - mannitol

List 6 items utilized for gastric tube placement:

1. *Check tube placement* before administering any fluids, medications, or feeding, using multiple techniques: - x-ray, pH testing, aspirate characteristics, external length marking, and carbon dioxide monitoring 2. *Check gastric residual* before each feeding or every 4 to 6 hours during a continuous feeding. - High gastric residual volumes (200 to 250 mL or greater) can be associated with high risk for aspiration and aspiration-related pneumonia 3. *Assess the abdomen for abnormalities*. Assess for bowel sounds at least once per shift to check for the presence of peristalsis and a functional intestinal tract. 4. Make sure the *patient is as upright position* as possible during feeding. If the patient is in bed during feedings, elevate the head of the bed at least 30 degrees during feeding and for 1 hour afterward to prevent reflux and aspiration. 5. • *Prevent contamination* during enteral feedings by maintaining the integrity of the feeding system and using proper technique. *Closed systems*, consisting of a sterile, prefilled, ready-to-hang container, reduce the opportunity for bacterial contamination of the feeding formula. An *open system* exists when formula from a can or bottle is added to a feeding setup. Always check the expiration date of formula. 6. *Medications may be administered* through a feeding tube, but *never* give them while a feeding is being infused. Administer liquid forms of medications whenever possible. *Never add medications directly to the formula*; some drugs become ineffective when mixed with feeding formulas; medications mixed in feeding formulas may cause clogging of the feeding tube. It is very important to flush the tube with water before, between, and after the administration of medications.

Furosemide

1. Most commonly used diuretic 2. Loop diuretic 3. Administer IVP, IM, or PO IVP- dosages vary, dilute, and push slowly to prevent ototoxicity 4. Side Effects are Rare

1. Patient position: High Fowler position 90 degrees, or elevate the head of the bed 45 degrees if the patient is unable to maintain an upright position. 2.Measure the length of tubing needed: Measure the distance to insert the tube by placing the tip of the tube at the patient's nostril and extending the tube to the tip of the earlobe and then to the tip of the xiphoid process. Mark the tube with an indelible marker. 3. What PPE? Sterile gloves 4. Comfort measures and head positioning: ask the patient to slightly flex the head back against the pillow. While inserting the tube. Provide tissues for tearing or watering of eyes. Offer comfort and reassurance to the patient. 5. Once you are ready to advance the tube after you have reached the pharynx: Instruct the patient to touch the chin to the chest. Encourage the patient to sip water through a straw or swallow even if no fluids are permitted. Advance the tube in a downward and backward direction when the patient swallows 6. if: - Gagging/coughing: stop advancing the tube and check placement of the tube with tongue blade and flashlight. If the tube is curled, straighten the tube and attempt to advance again. Keep advancing the tube until pen marking is reached. - Resistance: Rotate tube if it meets resistance. - Distress/cyanosis: Discontinue the procedure and remove the tube - Secure the tube: a. Cut a 4-inch piece of tape and split the bottom 2 inches or use packaged nose tape for NG tubes. b. Place the unsplit end over the bridge of the patient's nose . c. Wrap split ends under and around the NG tube. Be careful not to pull the tube too tightly against the nose. - Care while NGT in place: - Assist with or provide oral hygiene at 2- to 4-hour intervals. - Lubricate the lips generously and clean nares and lubricate as needed. - Offer analgesic throat lozenges or anesthetic spray for throat irritation if needed.

Assess for signs of aspiration while eating:

1. Sudden appearance of severe coughing 2. Choking 3. Cyanosis 4. Voice changes 5. Hoarseness/gurgling after swallowing 6. Frequent throat clearing after meals 7. Regurgitation through the nose or mouth.

4. The nurse is performing a nutritional assessment of an obese patient who visits a weight control clinic. What information should the nurse take into consideration when planning a weight reduction plan for this patient? a. To lose 1 pound/week, the daily intake should be decreased by 200 calories. b. One pound of body fat equals approximately 5,000 calories. c. Psychological reasons for overeating should be explored, such as eating as a release for boredom. d. Obesity is very treatable, and 50% of obese people who lose weight maintain the weight loss for 7 years.

c Psychological reasons for overeating should be explored, such as eating as a release for boredom.

Total parenteral nutrition:

a highly concentrated, hypertonic nutrient solution, accessed through a central venous line. - provides calories; restores nitrogen balance; and replaces essential fluids, vitamins, electrolytes, minerals, and trace elements. - can promote tissue and wound healing and normal metabolic function. - provides the bowel a chance to heal and reduces activity in the gallbladder, pancreas, and small intestine. - used to improve a pt's response to surgery

8. The nurse researches factors that may alter nutrition. Which statements accurately describe factors that influence nutritional status? (Select all that apply.) a. During adulthood, there is an increase in the basal metabolic rate with each decade. b. Because of the changes related to aging, the caloric needs of the older adult increase. c. During pregnancy and lactation, nutrient requirements increase. d. Nutritional needs per unit of body weight are greater in infancy than at any other time in life. e. Men and women differ in their nutrient requirements. f. Trauma, surgery, and burns decrease nutrient requirements.

c, d, e c. During pregnancy and lactation, nutrient requirements increase. d. Nutritional needs per unit of body weight are greater in infancy than at any other time in life. e. Men and women differ in their nutrient requirements.

6. A nurse is evaluating patients to determine their need for total parenteral nutrition (TPN). Which patients would be the best candidates for this type of nutritional support? Select all that apply. a. A patient with irritable bowel syndrome who has intractable diarrhea b. A patient with celiac disease not absorbing nutrients from the GI tract c. A patient who is underweight and needs short-term nutritional support d. A patient who is comatose and needs long-term nutritional support e. A patient who has anorexia and refuses to take foods via the oral route f. A patient with burns who has not been able to eat adequately for 5 days

a, b, f. Assessment criteria used to determine the need for TPN include an inability to achieve or maintain enteral access; motility disorders; intractable diarrhea; impaired absorption of nutrients from the GI tract (patient with celiac disease) and when oral intake has been or is expected to be inadequate over a 7- to 14-day period (Worthington & Gilbert, 2012; A.S.P.E.N., 2002). TPN promotes tissue healing and is a good choice for a patient with burns who has an inadequate diet. Oral intake is the best method of feeding; the second best method is via the enteral route. For short-term use (less than 4 weeks), a nasogastric or nasointestinal route is usually selected. A gastrostomy (enteral feeding) is the preferred route to deliver enteral nutrition in the patient who is comatose because the gastroesophageal sphincter remains intact, making regurgitation and aspiration less likely than with NG tube feedings. Patients who refuse to take food should not be force fed nutrients against their will.

Administer cola to remove the clog. d. Replace the tube with a new one.

a. In order to remove a clog in a feeding tube, the nurse should try using warm water and gentle pressure to unclog it. A stylet should never be used to unclog a tube, and cola and meat tenderizers have not been shown effective in removing clogs. The nurse should first attempt to remove the clog, and if unsuccessful, the tube should be replaced.

7. A nurse is feeding a patient who states that she is feeling nauseated and can't eat what is being offered. What would be the most appropriate initial action of the nurse in this situation? a. Remove the tray from the room. b. Administer an antiemetic and encourage the patient to take small amounts. c. Explore with the patient why she does not want to eat her food. d.

Stroke the underside of the patient's chin to promote swallowing. b. Serve meals in different places and at different times. c. Offer a whole tray of various foods to choose from. d. Avoid between-meal snacks to ensure hunger at mealtime.

a. To feed a patient with dementia, the nurse should stroke the underside of the patient's chin to promote swallowing, serve meals in the same place and at the same time, provide one food item at a time since a whole tray may be overwhelming, and provide between-meal snacks that are easy to consume using the hands.

9. A nurse is caring for a newly placed gastrostomy tube of a postoperative patient. Which nursing action is performed correctly? a. The nurse dips a cotton-tipped applicator into sterile saline solution and gently cleans around the insertion site. b. The nurse wets a washcloth and washes the area around the tube with soap and water. c. The nurse adjusts the external disk every 3 hours to avoid crusting around the tube. d. The nurse tapes a gauze dressing over the site after cleansing it.

a. When caring for a new gastrostomy tube, the nurse would use a cotton-tipped applicator dipped in sterile saline to gently cleanse the area, removing any crust or drainage.

1. A nurse who is planning a diet for a patient who has anorexia chooses nutrients that supply energy to the body including: (Select all that apply.) a. Vitamins b. Minerals c. Carbohydrates d. Protein e. Water f. Lipids

c, d, f c. Carbohydrates d. Protein f. Lipids

15. A nurse performs presurgical assessments of patients in an ambulatory care center. Which patient would the nurse report to the surgeon as possibly needing surgery to be postponed? a. A 19-year-old patient who is a vegan b. An elderly patient who takes daily nutritional drinks c. A 43-year-old patient who takes ginko bilboa and an aspirin daily d. An infant who is breast-feeding

c. A patient taking gingko biloba (an herbal), aspirin, and vitamin E (dietary supplement) may have to have surgery postponed due to an increased risk for excessive bleeding, because each of these substances have anticoagulant properties. Being a vegan should not affect surgery unless the patient has serious nutritional deficiencies. Drinking nutritional drinks and breast-feeding do not adversely affect the outcomes of surgery.

1. A nurse is estimating caloric requirements for a female patient whose healthy weight is 120 pounds and whose activity level is moderate. This patient's recommended total daily calories is: a. 1,200 b. 1,440 c. 1,560 d. 1,680

d 1,680

2. A nurse is helping an overweight female patient to devise a meal plan to lose 2 pounds per week. How many calories would the patient need to delete per day in order to accomplish this goal? a. 250 calories b. 500 calories c. 750 calories d. 1000 calories

d. 1 lb (0.45 kg) of body fat equals about 3,500 cal. Therefore, to gain or lose 1 lb (0.45 kg) in a week, daily calorie intake should be increased or decreased, respectively, by 500 cal (3,500 cal divided by 7 days = 500 cal/day). Similarly, a weight gain or loss of 2 lb (0.9 kg) per week would require an adjustment of 1,000 cal/day.

12. Which of the following nursing diagnoses would be most appropriate for a patient with a body mass index (BMI) of 18? a. Risk for Imbalanced Nutrition: More Than Body Requirements b. Imbalanced Nutrition: More Than Body Requirements c. Readiness for Enhanced Nutrition d. Imbalanced Nutrition: Less Than Body Requirements

d. A patient with a body mass index (BMI) of 18 is considered underweight, therefore a diagnosis of Imbalanced Nutrition: Less than Body Requirements is appropriate. The patient is not at risk for imbalanced nutrition because it is already a problem and certainly is not experiencing nutrition that is more than body requirements. Readiness for Enhanced Nutrition is appropriate when there is a healthy pattern of nutrient intake that is sufficient for meeting metabolic needs and can be strengthened and enhanced.

11. A patient who is moved to a hospital bed following throat surgery is ordered to receive continuous tube feedings through a small-bore nasogastric tube. Following placement of the tube, which nursing action would the nurse initiate to ensure correct placement of the tube? a. Auscultate the bowel sounds. b. Measure the gastric aspirate pH. c. Measure the amount of residual in the tube. d. Order radiographic examination of the tube.

d. Although a radiographic examination exposes the patient to radiation and is costly, it is still the most accurate method to check correct tube placement. Other methods that can be used are aspiration of gastric contents and measurement of the pH of the aspirate. The recommended method for checking placement, other than a radiograph, is measuring the pH of the aspirate. Visual assessment of aspirated gastric contents is also suggested as a tool to check placement. In addition, the length of the exposed tube is measured after insertion and documented. Tube length should be checked and compared with this initial measurement, in conjunction with the previous two methods for checking tube placement. The auscultatory method is considered inaccurate and unreliable. Measurement of residual amount does not confirm placement.

10. A nurse is assessing a patient who has been NPO (nothing by mouth) prior to abdominal surgery. The patient is ordered a clear liquid diet for breakfast, to advance to a house diet as tolerated. Which assessments would indicate to the nurse that the patient's diet should not be advanced? a. The patient consumed 75% of the liquids on her breakfast tray. b. The patient tells you she is hungry. c. The patient's abdomen is soft, nondistended, with bowel sounds. d. The patient reports fullness and diarrhea after breakfast.

d. Tolerance of diet can be assessed by the following: absence of nausea, vomiting, and diarrhea; absence of feelings of fullness; absence of abdominal pain and distention; feelings of hunger; and the ability to consume at least 50% to 75% of the food on the meal tray.

5. A nurse is feeding a patient who is experiencing dysphagia. Which nursing intervention would the nurse initiate for this patient? a. Feed the patient solids first and then liquids last. b. Place the head of the bed at a 30-degree angle during feeding. c. Puree all foods to a liquid consistency. d. Provide a thirty-minute rest period prior to mealtime.

d. When feeding a patient who has dysphagia, the nurse should provide a 30-minute rest period prior to mealtime to promote swallowing; alternate solids and liquids when feeding the patient; sit the patient upright or, if on bedrest, elevate the head of the bed at a 90-degree angle; and initiate a nutrition consult for diet modification and food size and/or consistency.

Nasogastric Tube (NGT) Placement and Care: Confirmation of placements by:

o *Radiographic exam*: The standard procedure to verify initial placement of a feeding tube (most reliable) - X-ray only confirms the position of the tube at the time it was taken.(it can move) Placement must be checked frequently while the tube is in place. o *Assess aspirate*: The recommended method for checking placement, other than radiograph, is measuring the pH of the aspirate.(when continuous feedings are in use, pH becomes less helpful, because the nutritional formula buffers the pH of gastrointestinal secretions) - Visual assessment of aspirated gastric contents is also suggested as a tool to check placement o *Auscultate injected air*: An old technique of auscultation of air injected into a feeding tube has proved unreliable and may result in tragic consequences if used as an indicator of tube placement - Therefore, do not use it to confirm feeding tube placement.

Diuretics

referred to as water pills/fluid pills- causes the body to inc. urinary output) Therapeutic effect is diuresis

Peripheral parenteral nutrition:

the administration of nutritional support via the intravenous route, accessed in a peripheral vein. - Pt's who can't meet their nutritional needs by the oral or enteral routes may require intravenous nutritional supplementation. - prescribed for patients who have nonfunctional: - gastrointestinal (GI) - comatose - Pt's that need high caloric and nutritional needs due to illness or injury - pt's undergoing aggressive cancer therapy and those recovering from extensive burns, surgery, sepsis, or multiple fractures.

Providing Parenteral Nutrition: What is it?

the administration of nutritional support via the intravenous route. - Pt's who can't meet their nutritional needs by the oral or enteral routes may require intravenous nutritional supplementation.

When placing a nasogastric or nasoenteric tube:

the patient is placed in a high-Fowler's position to facilitate *passage of the tube* and to prevent *aspiration*.

Assist Patients with Eating and Feeding Patients with Dysphagia:

•Allow at least a *30 minute* rest period before mealtime and avoid administration of *sedatives and hypnotics* •Positioning: *90* degrees (high Fowler) •To enhance sense of taste: apply *mouth care* •Involve the patient as much as possible •Create a relaxed comfortable environment by sitting at pt's eye level and make eye contact.
