1. A nurse is teaching a client with Barrett's esophagus who is scheduled
to undergo an esophagogastroduodenoscopy (EGD). Which of the following

"This procedure can determine how well the lower part of your esophagus
works."
C.
"This procedure is performed while you are under general anesthesia."
D.
"This procedure can determine if you have colon cancer.": Correct Answer: B.
"This procedure can determine how well the lower part of your esophagus works."
An EGD is useful in determining the function of the esophageal lining and the extent
of inflammation, potential scarring, and strictures.
Incorrect Answers:A. A pH probe study, which involves the insertion of a specially
designed probe into the distal esophagus, is performed to monitor for the presence
of acid in the normally alkaline esophagus.
C. An EGD is performed while the client receives moderate sedation.
D. A colonoscopy is performed to detect colon cancer.
2. A nurse is caring for a client who has acute pancreatitis. Which of the
,following serum laboratory values should return to the expected reference
range within 72 hr of treatment beginning?

Lactic dehydrogenase: Correct Answer: C.
Amylase
Pancreatitis is the most common diagnosis for marked elevations in serum amylase.
Serum amylase begins to increase about 3 to 6 hours following the onset of acute
pancreatitis. The amylase level peaks in 20 to 30 hours and returns to the expected
reference range within 2 to 3 days.
Incorrect Answers:A. Elevated aldolase levels are caused by inflammation of the
muscles, also known as myositis. Aldolase levels are not affected by pancreatic
disorders.
B. Lipase levels in clients who have pancreatitis increase after a rise in serum
amylase and stay elevated for up to 14 days longer than amylase levels.
D. Lactic dehydrogenase (LDH) increases are typically seen in clients who have
anemia, leukemia, or liver damage.
3. A nurse is assessing a client who has a bleeding duodenal ulcer. Which of

Incorrect Answers:A. Cornflakes do not contain gluten and do not have to be omitted
from the diet of a child who has celiac disease.
B. Milk is gluten-free and does not have to be eliminated from the diet of a child who
has celiac disease.
C. Canned fruits without additives are gluten-free and do not have to be eliminated
from the diet of a child who has celiac disease.
5. A nurse is planning an in-service training session regarding nutrition. Which
