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 C
Explanation
Choice A rationale
Monitoring peripheral pulses every 8 hours is not a specific intervention for a client who has acute pancreatitis. While it is important to monitor peripheral pulses as part of overall patient assessment, it does not directly address the needs of a patient with acute pancreatitis.
Choice B rationale
Ambulating the client three times daily is not a specific intervention for a client who has acute pancreatitis. While physical activity is generally beneficial for overall health, it does not directly address the needs of a patient with acute pancreatitis, especially during an acute attack.
Choice C rationale
Maintaining NPO (nothing by mouth) status is a common intervention for a client who has acute pancreatitis. This allows the pancreas to rest and recover, reducing inflammation and pain.
Choice D rationale
Measuring urine output every 4 hours is not a specific intervention for a client who has acute pancreatitis. While it is important to monitor urine output as part of overall patient assessment, it does not directly address the needs of a patient with acute pancreatitis.
Correct Answer is A
Explanation
Choice A rationale
Calling for pain medication before the previous dose wears off is an effective strategy for managing postoperative pain. This approach helps maintain a consistent level of pain control, which can enhance comfort and facilitate recovery.
Choice B rationale
Waiting for the nurse to evaluate the pain before asking for more medication can result in periods of uncontrolled pain, which can hinder recovery. Pain should be managed proactively, not reactively.
Choice C rationale
Calling for pain medication as the pain becomes intolerable is not an effective pain management strategy. Pain should be controlled before it reaches this level.
Choice D rationale
Asking for less medication to avoid addiction is not a recommended approach to pain management. While it’s important to use opioids judiciously, under-treating pain can hinder recovery and lead to unnecessary suffering. PancreatitisPancreatitis Explore
