MULTIPLE CHOICE

 

1. Select the statement that best reflects the functional components of the gastrointestinal (GI) tract.

a.	The GI tract is a continuous pathway from mouth to rectum.
b.	Peristaltic waveforms produce agitation, which digests large food particles.
c.	The alimentary canal extends from the mouth to the anus.
d.	The microscopic ecosystem of the GI tract is an unbalanced colony of germs.

 

 

ANS:  C

The GI tract, or alimentary canal, is a continuous tubelike structure that extends the entire length of the trunk. The tract includes the mouth; pharynx; esophagus; stomach; small intestine, consisting of the duodenum, jejunum, and ileum; and large intestine, which consists of the cecum, ascending colon, transverse colon, descending colon, sigmoid colon, rectum, and anus.

c.	duodenum.
d.	bronchial merge.

 

 

ANS:  B

The esophagus begins at C6 and passes through the neck posterior to the trachea.

3. Exposure of intra-abdominal anatomy is crucial to safe surgery and employs varied instruments, applications of highly technical energy sources, patient manipulations, light, and imaging. What is unique to the laparoscopic approach that promotes exposure?

a.	Self-retaining retractors
b.	Automatic rod-lens fiberscope
c.	Carbon dioxide pneumoperitoneum
d.	Endoscopic fan blades

 

 

ANS:  C

Abdominal insufflation with carbon dioxide expands the abdominal compartment, permitting better visualization and room to manipulate instruments.

4. Select the statement that most correctly matches a risk factor for adhesions with an appropriate preventive strategy.

a.	Multiple surgeries may be managed with the use of sequential compression devices.
b.	Glove powder adhesions can be prevented with cellulose mist.
c.	Patients with endometriosis may be best served with a laparoscopic approach.
d.	Fibrous bands within the peritoneum can be treated with sterile talcum powder.

 

 

ANS:  C

Adhesions may also develop as a result of radiation-induced endarteritis, endometriosis, pelvic inflammatory disease (PID), or Crohn’s disease. Preventive measures include the following: minimizing tissue trauma and inflammation with meticulous surgical technique and using the laparoscopic approach when indicated.

5. The general risks associated with gastrointestinal surgery parallel those risks associated with most abdominal procedures. Select a complication that is the most typical risk associated with surgery of the large bowel.

a.	Colitis
b.	Peritonitis
c.	Paralytic ileostomy
d.	Intestinal obstruction

 

 

ANS:  B

The risks for injury or failure to achieve the intended outcome are equally present in GI surgery as in any surgical or invasive procedure. The surgical and anesthesia experience challenges the immune system and poses many risks of introducing endogenous and exogenous microorganisms.
