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 ["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.

A. Allowing grieving B. Preventing aspiration C. Managing pain relief D. Maintaining nutritional intake

Correct Answer is B

Explanation

Choice A rationale
While allowing grieving is an important aspect of holistic care for a client with esophageal cancer, it is not the priority nursing intervention. Emotional support and counseling are crucial, but they do not take precedence over interventions aimed at maintaining the client’s physical health.
Choice B rationale
Preventing aspiration is the priority nursing intervention for a client with esophageal cancer. Aspiration, or the inhalation of food, stomach acid, or saliva into the lungs, can lead to pneumonia and other serious complications. Therefore, measures to prevent aspiration, such as educating the client on safe swallowing techniques, elevating the head of the bed during meals, and monitoring for signs of aspiration, are crucial.
Choice C rationale
Managing pain relief is an important aspect of care for a client with esophageal cancer, but it is not the priority nursing intervention. Pain management strategies, such as administering prescribed analgesics and providing comfort measures, are part of a comprehensive care plan

but do not take precedence over interventions aimed at preventing immediate life-threatening complications like aspiration.
Choice D rationale
Maintaining nutritional intake is an important aspect of care for a client with esophageal cancer, but it is not the priority nursing intervention. Nutritional support, such as providing a balanced diet, encouraging small frequent meals, and possibly arranging for a consultation with a dietitian, are important but do not take precedence over interventions aimed at preventing immediate life-threatening complications like aspiration.
