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

Answer and Explanation

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 A

Explanation

Choice A rationale
Painful swallowing, also known as dysphagia, is a common symptom of Gastroesophageal Reflux Disease (GERD)345. GERD is a chronic condition where stomach acid frequently flows back into the tube connecting your mouth and stomach.
Choice B rationale
Absence of saliva is not typically associated with GERD. In fact, increased salivation may occur as the body’s response to neutralize stomach acid.
Choice C rationale
A sweet taste in the mouth is not a common symptom of GERD. The regurgitation of stomach acid into the throat or mouth can leave a sour or bitter taste.
Choice D rationale
A metallic taste in the mouth is not a typical symptom of GERD. As mentioned, the regurgitation of stomach acid can cause a sour or bitter taste.

Correct Answer is ["2"]

Explanation

Step 1: Identify the dose of aspirin the nurse needs to administer, which is 650 mg. Step 2: Identify the available dose, which is 325 mg per tablet.
Step 3: Calculate the number of tablets needed by dividing the required dose by the dose available per tablet. So, 650 mg ÷ 325 mg/tablet.
Step 4: The calculation gives us 2. Therefore, the nurse should administer 2 tablets.
