ATI Gastrointestinal System Quizlet
1. Which of the following definitions best describes diverticulosis?
- A. An inflamed outpouching of the intestine
- B. A noninflamed outpouching of the intestine
- C. The partial impairment of the forward flow of intestinal contents
- D. An abnormal protrusion of an organ through the structure that usually holds it
Correct answer: B
Rationale: The correct answer is B: 'A noninflamed outpouching of the intestine.' Diverticulosis refers to the presence of small, bulging pouches (diverticula) that can form in the lining of the digestive system, especially the colon. These pouches are typically noninflamed. Choice A is incorrect because it describes diverticulitis, which is the inflammation of these pouches. Choice C is incorrect as it defines bowel obstruction, not diverticulosis. Choice D is incorrect as it refers to a hernia, not diverticulosis.
2. A client with liver dysfunction is having difficulty with protein metabolism. The nurse anticipates that the results of which of the following serum laboratory studies will be elevated?
- A. Lactic acid
- B. Ammonia
- C. Albumin
- D. Lactase
Correct answer: B
Rationale: During deamination of proteins, the liver splits the amino group from the carbon-containing compound, which results in the formation of ammonia and a carbon residue. The liver then converts the toxic ammonia substance into urea, which can be excreted by the kidneys. Clients with liver dysfunction may have high serum ammonia levels as a result.
3. The physician orders a Salem sump tube for gastrointestinal intubation. The nurse prepares for the insertion and obtains which of the following items from the supply room?
- A. A tube with a single lumen that connects to suction
- B. A tube with a large lumen and an air vent
- C. A Sengstaken-Blakemore tube
- D. A Dobbhoff weighted tube
Correct answer: B
Rationale: A tube with a large lumen and an air vent is a Salem sump tube. A tube with a single lumen is called a Levin’s tube. A Sengstaken-Blakemore tube is used to control bleeding in the esophagus. A Dobbhoff weighted tube is used for feedings.
4. The nurse assesses the client's understanding of the relationship between body position and gastroesophageal reflux. Which response would indicate that the client understands measures to avoid problems with reflux while sleeping?
- A. I can elevate the foot of the bed 4 to 6 inches.
- B. I can sleep on my stomach with my head turned to the left.
- C. I can sleep on my back without a pillow under my head.
- D. I can elevate the head of the bed 4 to 6 inches.
Correct answer: D
Rationale: Sleeping with the head of the bed elevated encourages movement of food through the esophagus by gravity. By fostering esophageal acid clearance, gravity helps keep the acidic pepsin and alkaline biliary secretions from contacting the esophagus. Elevating the foot of the bed does not affect clearance of esophageal acid. Sleeping on the stomach with the head turned to the left will not decrease reflux incidence. Sleeping flat without a pillow under the head does not enhance clearance.
5. The nurse is caring for a client with a diagnosis of cirrhosis and is monitoring the client for signs of portal hypertension. Which initial sign, if noted in the client, indicates the presence of portal hypertension?
- A. Flat neck veins
- B. Hypotension
- C. Weak pulse
- D. Crackles on auscultation of the lungs
Correct answer: D
Rationale: Clinical signs and symptoms or portal hypertension are identical to those of heart failure and include jugular vein distention, lung crackles, and decreased perfusion to all organs. Initially, the client may have hypertension, flushed skin, and a bounding pulse.
