What does the lab test for H pylori involve?
Correct Answer
A. Tests to determine whether the bacterium H pylori is present in your body
Explanation
The lab test for H pylori involves conducting tests to determine whether the bacterium H pylori is present in your body. This could include tests on stool, urine, or blood samples to detect the presence of the bacterium.
2.
What is examined in the lab to detect if the H pylori is present?
Correct Answer
A. Blood, stool, breath test
Explanation
Blood, stool, and breath tests are examined in the lab to detect the presence of H pylori. H pylori is a bacterium that infects the stomach and can cause various gastrointestinal issues. Blood tests can detect the presence of antibodies produced by the body in response to the infection. Stool tests can identify the presence of H pylori antigens or genetic material in the feces. Breath tests involve the patient drinking a solution containing a specific substance, which is metabolized by H pylori if present, leading to the release of certain gases that can be detected in the breath. These tests are commonly used to diagnose H pylori infections.
3.
What is the most accurate test for H pylori?
Correct Answer
A. The breath test
Explanation
The most accurate test for H pylori is the breath test. This test involves the patient consuming a special liquid or meal that contains a substance that is metabolized by the H pylori bacteria. If the bacteria are present in the stomach, they will produce certain gases that can be detected in the patient's breath. This test is highly accurate and non-invasive, making it a preferred method for diagnosing H pylori infections. Stool tests, blood tests, and urine tests are also used to diagnose H pylori, but the breath test is considered the most accurate.
4.
What is the least accurate test for H pylori?
Correct Answer
A. Blood test
Explanation
The blood test is the least accurate test for H pylori because it detects antibodies that may still be present even after the infection has been treated or resolved. This can lead to false positive results, indicating the presence of H pylori when it is actually absent. Other tests, such as the breath test or the stool test, are more reliable as they directly detect the presence of the bacteria.
5.
How do you know that you have H pylori through a breath test?
Correct Answer
D. If your breath sample contains the radioactive carbon in the form of carbon dioxide
Explanation
The presence of radioactive carbon in the form of carbon dioxide in the breath sample indicates the presence of H pylori. This is because during the breath test, the patient is given a drink containing a small amount of radioactive carbon. If H pylori is present in the stomach, it breaks down the urea in the drink, releasing carbon dioxide that contains the radioactive carbon. This can be detected in the breath sample, confirming the presence of H pylori.
6.
What's an endoscopy?
Correct Answer
A. It's when your doctor uses a scope to examine your upper digestive system
Explanation
An endoscopy is a medical procedure in which a doctor uses a scope, a long flexible tube with a light and camera at the end, to examine the upper digestive system. This allows the doctor to visually inspect the esophagus, stomach, and the beginning of the small intestine. The scope is inserted through the mouth and guided down the throat, providing real-time images of the digestive tract on a monitor. This procedure is commonly used to diagnose and treat conditions such as ulcers, inflammation, tumors, and bleeding in the upper gastrointestinal tract.
7.
When does the doctor recommend an endoscopy?
Correct Answer
A. For old patients or for patients who have signs of bleeding
Explanation
The doctor recommends an endoscopy for old patients or for patients who have signs of bleeding because these individuals are at a higher risk for certain medical conditions that can be detected through an endoscopy. Older patients may have a higher likelihood of developing conditions such as gastrointestinal cancers or ulcers, which can be identified through this procedure. Additionally, patients who are experiencing signs of bleeding may have internal bleeding or other gastrointestinal issues that need to be investigated further. Therefore, an endoscopy is recommended in these cases to diagnose and treat any potential underlying conditions.
8.
What's the other term for Upper gastrointestinal series?
Correct Answer
A. Barium swallow
Explanation
The correct answer is "Barium swallow". This is another term for an upper gastrointestinal series, which is a diagnostic test that involves swallowing a liquid called barium. The barium coats the inside of the esophagus, stomach, and small intestine, allowing them to be visible on X-ray. This test is used to evaluate the structure and function of the upper gastrointestinal tract and can help diagnose conditions such as ulcers, tumors, and blockages.
9.
What is an Upper gastrointestinal series?
Correct Answer
C. It's series of X-rays of your upper digestive system
Explanation
An upper gastrointestinal series is a series of X-rays that are taken to examine the upper digestive system. This includes the esophagus, stomach, and small intestine. The X-rays are taken after the patient drinks a contrast material, which helps to highlight the digestive organs and make them more visible on the X-ray images. This procedure can help to diagnose conditions such as ulcers, tumors, and blockages in the upper digestive system. It is a non-invasive and relatively safe way to evaluate the structure and function of the upper gastrointestinal tract.
10.
What is examined during an upper gastrointestinal series?
Correct Answer
A. The esopHagus, the stomach, and the small intestines
Explanation
During an upper gastrointestinal series, the esophagus, stomach, and small intestines are examined. This procedure involves the use of contrast material, such as barium, which is ingested by the patient. X-ray images are then taken to visualize the anatomy and function of the upper digestive tract. This allows healthcare professionals to identify any abnormalities or conditions affecting the esophagus, stomach, or small intestines, such as ulcers, tumors, or blockages. By examining these specific organs, doctors can diagnose and monitor various gastrointestinal disorders.
