The physician orders a patient with a duodenal ulcer to take a UREA breath test. Which lab value will the test measure to determine if
H. Pylori is present?
Ammonia
Hydrochloric Acid
Potassium
Carbon Dioxide
The Correct Answer is D
Choice A rationale
The UREA breath test does not measure ammonia levels. While H. pylori can convert urea to ammonia and carbon dioxide, the test specifically measures the level of carbon dioxide in the breath.
Choice B rationale
The UREA breath test does not measure hydrochloric acid. Hydrochloric acid is produced by the stomach to aid in digestion, but it is not measured in the UREA breath test.
Choice C rationale
The UREA breath test does not measure potassium. Potassium is an important electrolyte in the body, but it is not related to the presence of H. pylori or the UREA breath test.
Choice D rationale
The UREA breath test measures carbon dioxide in the breath.
H. pylori bacteria break down urea into ammonia and carbon dioxide. Excess carbon dioxide in the breath is a sign of an H. pylori infection.

Correct Answer is B
Explanation
Choice A rationale
Development of gastric ulcers is not a common complication of an esophagogastroduodenoscopy (EGD) procedure. Gastric ulcers are typically caused by factors such as Helicobacter pylori infection or long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs), not by the EGD procedure itself.
Choice B rationale
Perforation of the esophagus, stomach, or duodenum is a potential complication of an EGD procedure. During an EGD, a flexible tube with a camera is inserted through the mouth and down into the gastrointestinal tract. If the tube accidentally punctures or tears the lining of the esophagus, stomach, or duodenum, it can cause a perforation. This is a serious complication that requires immediate medical attention.
Choice C rationale
While allergic reactions to the sedation medication used during an EGD procedure can occur, they are not a direct complication of the EGD procedure itself. Allergic reactions would be related to the specific medication used for sedation and not the procedure.
Choice D rationale
Infection at the site of the procedure is not a common complication of an EGD. The procedure is performed using aseptic technique to minimize the risk of infection.
Correct Answer is B
Explanation
Choice A rationale
Elevating the patient’s legs on two pillows is not typically a necessary action after a liver biopsy. This position does not directly aid in the recovery or prevention of complications related to a liver biopsy.
Choice B rationale
Positioning the patient on the right side after a liver biopsy is a common nursing intervention. This position applies pressure to the liver biopsy site, which can help minimize bleeding and facilitate clot formation at the biopsy site.
Choice C rationale
Keeping the patient in a high Fowler’s position is not typically recommended after a liver biopsy. This position does not provide direct benefits in terms of recovery or prevention of complications from a liver biopsy.
Choice D rationale
Ambulating the patient twice each shift is not typically recommended immediately after a liver biopsy. Rest is usually advised to allow the liver tissue to heal and to minimize the risk of bleeding.
