Practice Questions r/t the Gastrointestinal System and Nutrition Flashcards
Your client is receiving continuous nasogastric feedings. You know to change the tube feeding container and line every ______________
24 h
the tube feeding container and line are normally changed every 24 hours to prevent transmission of bacteria. The feedings themselves should infuse for no longer than 8 hours.
the most accurate assessment for correct placement of nasogastric tube is to:
- determine the pH of aspirate
- visualize the gastric area by X-ray
- inject air into the tube and auscultate over the gastric area for the sound of air entering the stomach
- palpate the gastric area following the injection of 100 cc of air into the tube
x-ray is the most accurate assessment of the correct placement of an NG tube as visual confirmation can be made about the position.
determining the pH of aspirate or auscultation over gastric area to hear sounds of injected air as it enters the stomach are ways to confirm placement - however, they are not the most accurate
palpation is not used to determine placement as injections of enough air to palpate would cause discomfort
a client experiencing upper gastrointestinal bleeding was stabilized in the emergency department and was admitted to the hospital for further evaluation. To determine the cause and specific site of the bleeding, the nurse will anticipate a prescription for which diagnostic test first?
- gastroscopy
- gastrointestinal x-rays
- fiberoptic colonoscopy
- gastric analysis
A gastroscopy would be the most likely diagnostic procedure since upper gastrointestinal bleeding is suspected. A gastroscopy allows direct visualization of the mucosal lining of the esophagus, stomach, and duodenum
gastrointestinal x-ray would be requested only if the gastroscopy was inconclusive and it was thought that additional information would be useful
fiberoptic colonoscopy would not be requested since the bleeding is occurring in the upper gastrointestinal tract. A fiberoptic colonoscopy allows direct visualization of the colon up to the ileocecal valve. It is used to diagnose conditions such as inflammatory bowel disease, strictures, and bleeding sites. This procedure allows for removal of polyps.
a gastric analysis is usually requested to analyze the pH and volume of the gastric contents. This test could assist in determining the cause of bleeding, such as high acidity of stomach contents. However, gastric analysis cannot locate specific sites of bleeding, since direct visualization is not possible.
a client who is to be weighed daily on bed scales is receiving continuous liquid feedings via a percutaneous endoscopic gastrostomy (PEG). An important nursing intervention would be to:
- weight the day’s feeding formula and add it to the client’s weight
- inform the physician that persons receiving continuous feedings cannot be weighted on bed scales
- defer the daily weights and record this deferment on the chart
- turn off the feed at least 30 minutes prior to weighing process
The percutaneous endoscopic gastrostomy (PEG) feeding should be turned off at least 30 minutes prior to the weighing process. This will decrease the risk of aspiration.
weighing the day’s feeding formula and adding it to the client’s weight is not an appropriate or common practice
clients receiving continuous PEG feedings can be weighed on bed scales
there is no clinical reason to defer daily weights
your client had a resection of a diseased portion of the ileum. Which instructions will you give the client about performing deep breathing and coughing exercises?
- sit in an upright position; take a deep breath, and then cough
- hold your abdomen firmly, take several deep breaths, and then cough 2 or 3 times as you exhale
- tighten your stomach muscles as you inhale and then cough forcefully
- raise your shoulders to expand your chest and then give a deep cough
You will instruct the client to hold the abdomen firmly, take several deep breaths, and then cough two or three times as they exhale. Effective splinting of the surgical site will allow the client to breathe deeply and cough more effectively. The client will experience less pain since stress on the suture line is relieved. The goal of coughing and deep breathing is to fully expand and aerate the lungs, thus allowing secretions to be coughed out. Effective coughing is always preceded by deep breathing.
When possible, the nurse should teach the postoperative client to maintain a sitting position for coughing and deep-breathing exercises. This position lowers abdominal organs and allows the diaphragm to expand fully. However, a sitting position may not be therapeutic or appropriate for all surgical clients
the client should not tighten stomach muscles when doing C&DB exercises. Also, it is not necessary that coughing be forceful. It would be helpful to have the client slightly flex the knees to take tension off the abdomen
the client should be taught to breathe deeply from the diaphragm. Raising the shoulders tends to facilitate shallow breathing, not deep breathing.
ingestion of which of the following foud has been found to exacerbate gastroesophageal reflux disease?
- poultry
- pasta
- herbs and spices
- caffeine and chocolate
Ingestion of caffeine and chocolate may exacerbate gastroesophageal reflux. The reflux of the stomach contents into the esophagus is due in part to a lowering of esophageal sphincter pressure. Certain foods have been found to lower the sphincter pressure. These foods include caffeine, chocolate, peppermint, and fatty foods
A client is experiencing vomiting and gastrointestinal bleeding. You are to prepare an intravenous infusion that contains potassium chloride. The purpose of administering potassium chloride is t:
- replace the potassium lost in the urine
- restore lost potassium reserves
- provide potassium to promote excretion of sodium
- replace the potassium that is being lost through vomiting
Administering potassium chloride will replace the potassium that is being lost through vomiting. Potassium is one of the electrolytes contained in gastric secretions. When excessive vomiting or suctioning of gastric contents occurs, clients lose potassium. If potassium is not replaced, hypokalemia may occur.
potassium is usually lost in urine output during diuretic therapy
potassium cannot be stored in the body. A minimum of 40 mEq a day must be consumed. A normal potassium level is 3.5 to 5.5 mEq/l
potassium does not promote excretion of sodium. When potassium is lost from the cells, sodium shifts into the cells to replace lost K+
your client had a subtotal gastrectomy and my experience the dumping syndrome as a direct result of:
- the removal of a large portion of the stomach
- hyperosmolar chyme
- consuming large quantities of food
- not resting after each meal
The dumping syndrome is a direct result of removing a large portion of the stomach. The dumping syndrome is a set of unpleasant vasomotor and gastrointestinal symptoms that occur in 10-50% of clients who have had gastric surgery. Food passes too rapidly from stomach remnant into the duodenum and jejunum. Symptoms include weakness, faintness, cramping, and diarrhea.
hyperosmolar chyme occurs as a result of food entering the duodenum and jejunum without proper mixing
consuming smaller meals, not drinking liquids with meals, and staying upright after meals can benefit those experiencing dumping syndrome - however th e opposites do not cause the condition
how many ounces of commercially prepared formula will contain 500 kcal of energy?
________________________
commercial formula and breast milk contain ~20kcal/oz so 25oz will be needed
a 10-lb baby requires how many kcal per day for energy?
- 100 kcal
- 500 kcal
- 1000 kcal
- 1500 kcal
babies require 105 to 110 kcal/kg/day
1 kg = 2.2 lbs
110x10/2.2=500kcal/day
A client is admitted to the hospital with Crohn’s disease. What does the nurse anticipate the assessment will reveal? (select all that apply)
a. diarrhea
b. jaundice
c. steatorrhea
d. ascites
e. dependent edema
f. shortness of breath
g. tachycardia
a - manifestations of Crohn’s disease include diarrhea, fatigue, abdominal pain, and weight loss. Crohn’s diseaseis a chronic, nonspecific inflammatory disorder of unknown origin that can affect any part of the GI tract. It is characterized by inflammation of segments of the GI tract. It is also called regional ileitis and regional enteritis
jaundice and steatorrhea (fatty stool) are symptoms of gallbladder disease
shortness of breath and tachycardia would be symptoms manifested in a COPD client
dependent edema and ascites are seen in right-sided congestive heart failure
Which of the following may result from prolonged gastroesophageal reflux disease and can quickly become life threatening?
- pharyngitis
- colitis
- esophageal ulceration
- angina
3 - prolonged gastroesophageal reflux disease can quickly become life-threatening, causing esophageal ulceration. A repeated assault on the esophageal mucosa by acid reflux can cause erosion of the esophagus and hemorrhage this is an uncommon occurrence but can be morbid if not treated promptly. Symptoms may become very severe and constant with little relief from previously effective treatments. This is a medical emergency
the chest pains associated with angina may easily be confused with the heartburn associated with GERD, and vice versa. Although one does not cause the other, pain that may be cardiac in origin must always be considered when a client complains of chest pain
Which of the following diets would be most appropriate for a client who has hypercholesterolemia?
- hamburger patty, macaroni and cheese, iced tea
- baked chicken breast, apple, skim milk
- fish sticks, French fries, cola
- pizza, tossed salad, beer
2 - clients with hypercholesterolemia have elevated serum cholesterol levels, which have been found to contribute to the develompent of coronary artery disease. The consumption of low-fat food, such as white meats, fruits, vegetables, grins, and skimmed dairly products wil help lower serum lipid levels.
During a physical assessment your client tells you: “I belch a lot and when I lie down, undigested food comes up into my mouth. I have noticed a gurgling sound after eating, and I have a sour taste in my mouth”. You suspect:
- a diffuse esophageal spasm
- gastroesophageal reflux
- a hiatal hernia
- a pharyngoesophageal diverticulum
you will suspect a pharyngoesophageal diverticulum. A diverticulum is an outpouching of the mucosa that protrudes through a weak place in the esophageal musculature. Symptoms include dysphagia, belching, regurgitation of undigested food, gurgling sounds after eating (caused by fluid and food filling the diverticulum), coughing caused by trachea irritation, halitosis (bad breath), and a sour taste in the mouth caused by decomposing food lodged in the diverticulum
a diffuse esophageal spasm is caused by motor excitement of the esophagus that produces alternate periods of contractions and relaxation. Symptoms include dysphagia and chest pain
gastroesophageal reflux is characterized by backward flow of acidic contents of the stomach into the distal portion of the esophagus. Symptoms include pyrosis (heartburn), regurgitation, dysphagia, and a painful feeling of a lump in the throat
hiatal hernia type 1 is a sliding hernia where the upper stomach and the gastroesophageal junction are pushed upward in and out of the thorax. Type 2 is a herniation of a portion of the stomach through an opening (hiatus) into the esophagus. This condition is also known as esophageal or diaphragmatic hernia. Symptoms of types 1 and 2 include pyrosis and dysphagia
your client has a history of scarring as a result of repeated ulcerations and healings of ulcers distal to the pyloric sphincter. Recent complaints include epigastric fullness, pain, distention, nausea, vomiting, and anorexia. The client sates that the pain is worse at night. You suspect:
- peptic ulcer disease
- acute gastritis
- pyloric obstruction
- paralytic ileus
3 - a pyloric obstruction is suspected. Scarring at the pylorus is likely to cause pyloric obstruction. As a result of the obstruction, the contents of the stomach are unable to empty properly, which causes gastric fullness, distention, pain, nausea, and vomiting. When clients lie down at night, pain intensifies since the stomach is even less likely to be emptied by peristalsis
symptoms of peptic ulcer perforation include sudden onset of severe upper abdominal pain that spreads rapidly throughout the abdomen as the spillage of gastrointestinal contents invade the peritoneal cavity. Clients experience rigid, board-like abdomen. Respirations become shallow and rapid. Bacterial septicemia develops, causing fever and hypovolemic shock.
some of the symptoms of acute gastritis are similar to those of pyloric obstruction. However, the client’s history of scarring at the distal end of the pyloric sphincter is highly suggestive of pyloric obstruction.
a paralytic ileus is a postoperative complication. Peristalsis stops in a portion of the bowel, which causes diminished or absent bowel sounds. Abdominal distention occurs and the client complains of pain and feelings of fullness. A nasogastric tube is usually required to relieve distention and vomiting until normal bowel peristalsis resumes
Your client is experiencing the acute phase of ulcerative colitis. The client states, “ there is blood in my stools. I am afraid.” You will:
- check the client’s stools for the presence of occult blood
- recommend that the client keep a record of the number and description of stools
- notify the client’s physician immediately
- explain to the client that blood in the stools is expected in this condition
4 - the nurse should explain to the client that 90 to 100% of clients experiencing ulcerative colitis have blood, pus, and mucus in their stools. Understanding the nature and symptoms of the disease may help to alleviate the client’s anxiety.
it is not necessary to check for occult blood as blood in stool is a typical finding
clients should participate in maintaining a record of the number and description of stool, however, maintaining a record will not give the client information needed to allay anxiety about blood in the stool
nursing staff will record the number and description of stools - it is not necessary to notify a physician as this symptom is expected
A client with cirrhosis of the liver has a serum bilirubin level of 50 mg/dl. In order to evaluate these laboratory results, you need to know that the normal serum bilirubin level is:
- 0.2 to 1.0 mg/dl
- 3 to 10 mg/dl
- 10 to 20 mg/dl
- 20 to 30 mg/dl
normal serum bilirubin is 02. to 1.0 mg/dl.
a serum bilirubin of 50 mg/dl is associated with late-stage liver disease
Your client will have a permanent colostomy following a colon resection. You will teach the client that the colostomy should begin to function postoperatively within:
- 12 to 24 hours
- 2 to 4 days
- 4 to 5 days
- 5 to 6 days
The colostomy should begin to function within 2 to 4 days. It generally takes this long for peristalsis to be restored following abdominal surgery.
As peristalsis should return in 48-72 hours, any longer may suggest that complications such as a paralytic ileus should be suspected
a child 4 years of age is acutely ill. Which of the following nursing measures will be most helpful in meeting the child’s nutritional needs during the acutely ill period?
- serving foods that are lukewarm
- giving liquids through a straw
- offering small, frequent feedings of favourite foods
- allowing the client to select foods from the regularly scheduled meal trays
3 - frequent, small potions of favourite foods will allow periods of rest that prevent exhaustion and help the acutely ill child to meet their nutritional needs.
temperature of the food is not the issue. Although a straw may conserve energy, if the child does not enjoy the liquid it won’t matter if there is a straw or not
A client had an abdominoperineal resection with creation of an end colostomy. A sump drain was left in the client’s perineal wound. The purpose of this sump drain is to:
- allow for easy assessment of the character and volume of drainage
- allow for easy passage of flatus until peristalsis returns
- prevent contamination of the operative site secondary to frequent dressing changes
- allow wound healing from its lowest depth without forming an abscess
4 - the sump drain will allow wound healing to take place from its lowest depth without forming an abscess
the character and volume of drainage can be assessed by using a sump drain. However, this is not the primary purpose for the drain
flatus will be expelled from the colostomy, not the perineal wound
a sump drain can be contaminated as easily as a dressing
Your client has a gastric ulcer and is to receive aluminum hydroxide. The client asks, “why am I receiving aluminum hydroxide?” You will explain that the expected action of this drug is to:
1. aid in inhibiting the secretion of hydrochloric acid
aluminum hydroxide (Amphojel) is an antacid that neutralizes gastric secretions by buffering hydrochloric acid
antiulcer (histamine H2 antagonists) such as Tagamet inhibit secretion of hydrochloride while antacids like Amphojel simply buffer
aluminum hydroxide does not impact the breakdown of protein, or absorb air that has been swallowed
a 73-year-old client was admitted to the hospital with vomiting and gastrointestinal bleeding. The nurse prepares to administer an intravenous infusion that contains potassium chloride. The nurse will explain to the client that the purpose of the infusion is to:
- replenish the potassium that is being lost in the urine
- replace the potassium that is lost through vomiting
- restore the potassium level that elderly clients cannot maintain through normal dietary intake.
- Provide potassium in an amount sufficient to promote excretion of sodium chloride
2 - to replace potassium loss through vomiting. Potassium is one of the electrolytes contained in gastric secretions.
there is no indication potassium is being lost through urinary output. Clients who are treated with diuretics such as furosemide (Lasix) may lose potassium
as potassium is not stored in the body, people of all ages need potassium on a daily basis
You are encouraging an elderly client to increase intake of protein. To provide the greatest amount of protein, you will plan to add which of the following to 100 cc of milk?
- 50 cc of light cream and 2 tablespoons of corn syrup
- 30 grams of powdered skim milk and 1 egg
- 1 small scoop (90 grams) of vanilla ice cream and 1 tablespoon of chocolate syrup
- 2 egg yolks and 1 tablespoon of sugar
the skim milk powder and whole egg will provide the highest amount of protein
You are preparing a client for an upper gasterointestinal series. Which of the following explanations by the nurse would be both accurate and appropriate to share with the client
- in the x-ray department you will be asked to drink a thick liquid, and then several x-rays of the upper part of your digestive system will be taken at intervals
- you will be asked to swallow a tube so the physician can look at the lining of your stomach. X-rays will be taken at the same time
- you will be asked to swallow a substance that is radioactive, and then a series of x-rays will be taken. this will help to determine what is wrong with your stomach
- this test is carried out in the x-ray department. You will find it a little uncomfortable, but it’s not really painful
1 - in the x-ray department you will be asked to drink a thick liquid, and then several x-rays of the upper part of your digestive system will be taken at intervals. This is simple, factual and understandable to client
does not require client to swallow tube
the substance swallowed is radiopaque - not radioactive
a GI series is not uncomfortable
