APEA 3P Exam Prep- GI Questions with Correct Answers and Explanations The relationship between colon polyps and colon cancer is those polyps: eventually, all become malignant. have a slow progressi... on to colon cancer. have a rapid progression to colon cancer. have no relationship to colon cancer. B. Colon polyps are usually slow-growing and take a long time to progress to cancer. This is the reason that a colonoscopy does not need to be repeated annually. While not all polyps grow slowly, this is the usual progression. A 5-year-old has been diagnosed with pinworms. He lives with his mother. There are no other members of the household. How should his mother be managed? Reassure the mother that if she develops symptoms, she will need to be treated. Visually assess the mother’s rectum for redness or presence of worms. Have the mother collect a stool specimen and send it to the laboratory. Perform the “scotch tape” test and look at the collection under the microscope. D. The diagnosis of pinworms (Enterobiasis) is made by using a piece of scotch tape on a tongue depressor. It is touched against the patient’s rectum. The greatest yield of eggs will occur during the nighttime or early AM. Eggs will be found here if they are present. Worms and eggs are rarely found in stool specimens, so this is not a good plan. When the scotch tape is examined under a low power microscope, the eggs will be easily visualized since they are large and bean shaped. The finding of an adult worm would confirm the diagnosis. These are large enough to be seen with the naked eye. If the mother is symptomatic, she should be treated with or without a rectal exam. It is very likely she is infected. A patient has been diagnosed with hepatitis B. The most commonly reported risk factor is: drinking contaminated water. eating contaminated food. exposure to blood. sexual exposure. D. Hepatitis B is transmitted by blood and body fluids. While exposure to infected blood or blood products would significantly increase the risk of infection in unvaccinated people, this is much less likely than becoming infected via sexual exposure or IV drug use. Hepatitis A is transmitted via fecal-oral routes. Drinking contaminated water and eating contaminated food implicate hepatitis A as the etiologic agent. [Show More]
