Chapter 18 Flashcards
A serous membrane that lines the abdominal cavity and forms a protective cover for many abdominal structures is the A. Peritoneum B. Mediastinum C. Linea alba D. Mesentery E. Pleura
A. Peritonuem
The peritoneum is a serous membrane that lines the abdominal cavity and serves as a protective cover.
What part of the small intestine forms a C-shaped curve around the head of the pancreas? A. Duodenum B. Ileum C. Jejunum D. Falciform ligament E. Pylorus
A. Duodenum
The C-shaped curve around the head of the pancreas is the duodenum, the first 12 inches of the small intestine.
Peristalsis of intestinal contents is under the control of A. Cognitive processes B. Gravity C. Autonomic nervous system D. Fluid content of the stomach E. Cerebellum
C. ANS
The movement of food and digestive products is regulated by the autonomic nervous system
The esophagus travels a route from
A. Anterior to the trachea through the mediastinal cavity
B. Lateral to the trachea through the diaphragm
C. Left of the trachea through the peritoneum
D. The anterior trachea through the cardiac orifice
E. Behind the trachea through the mediastinal cavity
E. Behind the trachea through the mediastinal cavity
The esophagus lies posteriorly to the trachea, descends through the mediastinal cavity and through the diaphragm, and enters into the stomach. The esophagus connects the pharynx to the stomach.
Which organ is part of the alimentary tract? A. Pancreas B. Stomach C. Gallbladder D. Liver E. Spleen
B. Stomach
The term alimentary tract refers to the continuous tract from the mouth, esophagus, stomach, small intestine, large intestine, and anus
The superior most part of the stomach is the A. Body B. Fundus C. Pylorus D. Cardiac orifice E. Pyloric orifice
B. Fundus
The most superior aspect of the stomach is the fundus, followed by the body, and then the most distal part, the pylorus.
Which of the following is true regarding the stomach?
A. It lies in the lower abdominal cavity
B. It secretes gastric lipase that serves to digest protein
C. Very little absorption takes place in the stomach
D. The stomach produces most of the body’s bile
E. Pancreatic enzymes directly enter the stomach
C. Very little absorption takes place in the stomach
The stomach lies across the upper abdomen, secretes pepsin that digests protein and gastric lipase that emulsifies fats, and has a very small role in the absorption of nutrients. Secretions from the liver and pancreas enter the duodenum
The appendix is an extension of the A. ileum B. Cecum C. Ascending colon D. Transverse colon E. Descending colon
B. Cecum
The appendix is a blind-ended tube connected to the cecum, the site of the beginning of the large intestine, located in the right lower quadrant of the abdomen. It develops embryologically from the cecum.
When palpating the abdomen, you should note whether the liver is enlarged in the A. LUQ B. Midepigastric region C. Periumbilical area D. RUQ E. RLQ
D. RUQ
The liver is located in the right upper quadrant of the abdomen
One major function of the liver is to A. Secrete pepsin B. Emulsify fats C. Store glycogen D. Absorb bile E. Produce insulin
C. Store glycogen
The liver plays a metabolic role; it converts glucose to glycogen, stores it, and then converts glycogen back to glucose as needed by the body.
The majority of nutrient absorption takes place in the A. Stomach B. Small intestine C. Cecum D. Transverse colon E. Descending colon
B. Small intestine
Very little absorption takes place in the stomach; most absorption takes place in the small intestine. The cecum and transverse colon are part of the large intestine, and its major function is water reabsorption.
The major function of the large intestine is A. Water absorption B. Food digestion C. Carbohydrate absorption D. Mucous absorption E. Glycogen breakdown
A. Water absorption
The major function of the large intestine is the absorption of water and excretion of solid waste material in the form of stool. Mucous glands secrete large quantities of alkaline mucus.
Conversion of fat-soluble wastes to water-soluble material for renal excretion is a function of the A. Spleen B. Kidney C. Liver D. Pancreas E. Gallbladder
C. Liver
The liver is responsible for converting fat-soluble waste to water-soluble materials so the kidneys can excrete them as well as convert ammonia to urea.
Contraction of the gallbladder propels bile into the A. Stomach B. Duodenum C. Jejunum D. Ileum E. Cecum
B. Duodenum
With contraction of the gallbladder, bile is excreted into the duodenum.
Which abdominal organs also produce hormones and function as endocrine glands? A. Kidney and liver B. Liver and gallbladder C. Stomach and spleen D. Gallbladder and pancreas E. Pancreas and kidney
E. Pancreas and kidney
The pancreas produces pancreatic juices as well as insulin and glucagon; the kidneys produce urine as well as the hormones rennin and erythropoietin.
Which organ(s) are located in the retroperitoneal space? A. Kidneys B. Lungs C. Spleen D. Gallbladder E. Liver
A. Kidneys
The kidneys are located in the retroperitoneal space, lying behind the abdominal cavity and beside the abdominal aorta.
Mrs. G is 7 months pregnant and states that she has developed a problem with constipation. She eats a well-balanced diet and is usually regular. You should explain that constipation is common during pregnancy because of changes in the colorectal areas, such as
A. Decreased movement through the colon and increased water absorption from stool
B. Increased movement through the colon and increased salt taken from foods
C. Looser anal sphincter and less nutrients taken from foods
D. Tighter anal sphincter and less iron eliminated in the stool
E. Increased absorption of nutrients and water in the colon
A. Decreased movement through the colon and increased water absorption from stool
Constipation and flatus are more common during pregnancy because the colon is displaced, peristalsis is decreased, and water absorption is increased. The colon does not absorb nutrients, and a tighter sphincter tone is not related to pregnancy.
The most pronounced function change of the GI tract in older adults is
A. Decreased hydrochloric acid production
B. Increased motility
C. Decreased bile absorption
D. Decreased motility
E. Increased saliva secretion
D. Decreased motility
A decrease in motility of the gastrointestinal (GI) tract is the most pronounced GI change in older adults.
The family history of a patient with diarrhea and abdominal pain should include inquiry about cystic fibrosis because it
A. Only affects the GI tract
B. Is one cause of malabsorption syndrome
C. Is a curable condition with medical intervention
D. Is the mosts frequent cause of diarrhea in general practice
E. Is a common genetic disorder
B. Is one cause of malabsorption syndrome
Cystic fibrosis is an uncommon, chronic genetic disorder affecting multiple systems. In the gastrointestinal tract, it causes malabsorption syndrome because of pancreatic lipase deficiency. Steatorrhea and abdominal pain from increased gas production are frequent concerns.
Infants born weighing less than 1500g are at higher risk for A. Hepatitis A B. Necrotizing enterocolitis C. Urinary urgency D. Cystic fibrosis E. Pancreatitis
B. Necrotizing enterocolitis
Necrotizing enterocolitis is a gastrointestinal disease that mostly affects premature infants; it involves infection and inflammation that causes destruction of the bowel, and it becomes more apparent after feedings. Low birth weight does not relate to the development of hepatitis A, urinary urgency, cystic fibrosis, or pancreatitis.
Inspection of the abdomen should begin with the patient supine and the examiner A. Seated on the patient's right side B. Standing at the foot of the table C. Standing at the patient's left D. Walking around the table E. Seated on the patient's left side
A. Seated on the patient’s right side
This preferred initial position allows tangential viewing of the abdomen for improved assessment of abdominal contour.
Before performing an abdominal examination, the examiner should
A. Ascertain the patient’s HIV status
B. Have the patient empty his or her bladder
C. Don double gloves
D. Completely disrobe the patient
E. Uncover only the painful areas of the abdomen
B. Have the patient empty his or her bladder
The patient should empty the bladder to ensure an accurate examination of organs as well as to provide comfort for the patient.
