Med Surg Exam 1
The instructor has just finished teaching a group of students about the various organs of the upper gastrointestinal tract and possible disorders. The instructor determines that the teaching was successful when the students identify which structure as possibly being affected?
Stomach The upper gastrointestinal (GI) tract begins at the mouth and ends at the jejunum. Therefore, the stomach would be a component of the upper GI tract. The lower GI tract begins at the ileum and ends at the anus. The liver is considered an accessory structure.
The presence of mucus and pus in the stools suggests which condition?
Ulcerative colitis The presence of mucus and pus in the stools suggests ulcerative colitis. Watery stools are characteristic of small-bowel disease. Loose, semisolid stools are associated more often with disorders of the colon. Voluminous, greasy stools suggest intestinal malabsorption.
Medical management of a patient with peritonitis includes fluid, electrolyte, and colloid replacement. The nurse knows to prepare the initial, most appropriate intravenous solution. Which of the following is the correct solution? D10W D5W 0.9% NS 0.45% of NS
0.9% NS The administration of several liters of an isotonic solution is immediately prescribed. Hypovolemia occurs because massive amounts of fluid and electrolytes move from the intestinal lumen into the peritoneal cavity and deplete the fluid in the vascular space.
Which diagnostic produces images of the body by detecting the radiation emitted from radioactive substances?
Positron emission tomography (PET) PET produces images of the body by detecting the radiation emitted from radioactive substances. CT provides cross-sectional images of abdominal organs and structures. MRI uses magnetic fields and radio waves to produce an image of the area being studied. Fibroscopy of the upper GI tract allows direct visualization of the esophageal, gastric, and duodenal mucosa through a lighted endoscope.
An elderly client diagnosed with diarrhea is taking digoxin. Which electrolyte imbalance should the nurse be alert to? Hypokalemia Hypernatremia Hyponatremia Hyperkalemia
Hypokalemia The older client taking digitalis must be aware of how quickly dehydration and hypokalemia can occur with diarrhea. The nurse teaches the client to recognize the symptoms of hypokalemia because low levels of potassium intensify the action of digitalis, leading to digitalis toxicity.
The nurse is caring for a patient who is scheduled for a gastroscopy. What preparation is needed for a gastroscopy? Spray or gargle the back of the throat with local anesthetic. Have the patient lie in a dorsal position. Insert a nasogastric tube. Administer a micro Fleet enema
Spray or gargle the back of the throat with local anesthetic.
A client is having a diagnostic workup for reports of frequent diarrhea, right lower abdominal pain, and weight loss. The nurse is reviewing the results of the barium study and notes the presence of "string sign." What does the nurse understand that this is significant of? Crohn's disease Ulcerative colitis Diverticulitis Irritable bowel syndrome
Crohn's disease The most conclusive diagnostic aid for Crohn's disease has classically been a barium study of the upper GI tract that shows a "string sign" on an x-ray film of the terminal ileum, indicating the constriction of a segment of intestine.
A group of students is reviewing information about the liver and associated disorders. The group demonstrates understanding of the information when they identify which of the following as a primary function of the liver?
Excrete bile The liver forms and excretes bile, synthesizes amino acids from the breakdown of proteins, converts ammonia into urea, and synthesizes the factors needed for blood coagulation.
