A nurse is teaching a client with Barrett's esophagus who is scheduled to undergo an
esophagogastroduodenoscopy (EGD). Which of the following statements should the nurse include in the
teaching?
A.
"This procedure is performed to measure the presence of acid in your esophagus."
B.
"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.
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?
A.
Aldolase
B.
Lipase
,C.
Amylase
D.
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.
A nurse is assessing a client who has a bleeding duodenal ulcer. Which of the following findings should
the nurse expect?
A.
Emesis with a coffee-ground appearance
B.
Increased blood pressure
C.
Decreased heart rate
D.
Bright green stools - Correct Answer: A.
Emesis with a coffee-ground appearance
The nurse should expect a client who has a bleeding duodenal ulcer to have emesis that resembles
coffee-grounds or is bright red in color. Hematemesis indicates upper gastrointestinal bleeding, occurring
at or above the duodenojejunal junction.
,Incorrect Answers:B. A client who has a bleeding duodenal ulcer will have a decreased blood pressure
due to bleeding and fluid loss.
C. A client who has a bleeding duodenal ulcer will have a decreased heart rate due to bleeding and fluid
loss.
D. A client who has a bleeding duodenal ulcer will have melena stools, which are tarry or dark in color
and sticky.
A nurse is providing teaching to the guardian of a child who has celiac disease. Which of the following
foods should the nurse instruct the guardian to omit from the child's diet?
A.
Cornflakes
B.
Reduced-fat milk
C.
Canned fruits
D.
Wheat bread - Correct Answer: D.
Wheat bread
Clients who have celiac disease should eliminate as much gluten as possible from their diets. Wheat, rye,
and barley contain gluten and should be eliminated from the diet of a child who has celiac disease.
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.
A nurse is planning an in-service training session regarding nutrition. Which of the following minerals
should the nurse identify as involved in oxygen transportation?
A.
Zinc
B.
, Iron
C.
Phosphorus
D.
Magnesium - Correct Answer: B.
Iron
Iron transports oxygen by means of hemoglobin and myoglobin. It is also a component of enzyme
systems.
Incorrect Answers:A. Zinc plays a role in tissue growth and wound healing and supports immune
function, but it does not affect oxygen transport.
C. Phosphorus plays a role in bone and teeth formation and energy metabolism, but it does not affect
oxygen transport.
D. Magnesium affects enzyme and neurochemical activities and the excitability of cardiac and skeletal
muscles, but it does not affect oxygen transport.
A nurse is presenting an in-service training session about nutrition. How many of the amino acids must
be obtained from dietary intake?
A. 6
B. 9
C. 11
D. 15 - Correct Answer: B.
9
Proteins are made up of chains of amino acids, which are composed of carbon, hydrogen, oxygen, and
nitrogen. Nine amino acids are considered essential for the human body and must be obtained from
diet. These include histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine,
tryptophan, and valine.
Incorrect Answers:A. C. D. Of the 20 amino acids identified, the body is able to manufacture 11. These
are defined as nonessential amino acids.
