15 multiple choice 5 points
the physician has ordered a cholangiogram. the medical assistant explains to the patient that this is a(n):
x - ray of the colon.
x - ray of the pancreas.
x - ray of the kidney.
x - ray image of the bile vessels.

Explanation:

• Question 13: The liver's main secretion is bile, which aids in fat digestion. Pepsin is from the stomach, amino acids are breakdown products, and amylase is from the pancreas/salivary glands.
• Question 14: The combining form "proct/o" refers to the anus. "Peritoneum" has no such combining form, "pylorus" is related to the stomach - intestine junction (pylor/o), and "pancreas" is pancreat/o.
• Question 15: A cholangiogram is an X - ray of the bile vessels. "Colon" would be a colonogram (e.g., barium enema), pancreas - related imaging has other names (e.g., CT pancreas), and kidney X - ray is a nephrogram (e.g., IVP for kidneys, ureters, bladder in part).

Answer:

1. D. bile
2. A. Anus
3. D. x - ray image of the bile vessels
