A&P MODULE 2 CASE STUDY• Question 1 Module 2 Case Study AP1 1 out of 1 points Ben is a 6-month old infant who has a history of respiratory infections. His parents are concerned that his symptoms are worsening and bring him to his pediatrician, Dr. Johnson. They explain that he has a persistent cough and sometimes coughs up phlegm. He also experiences periodic wheezing and shortness of breath. Dr. Johnson notes that his weight and height have not increased as much as predicted since his last visit. He is concerned that Ben may have a genetic condition called Cystic Fibrosis. There are several ways to test for Cystic Fibrosis. In your own words, briefly describe 2 diagnostic tests that Dr. Johnson could use to determine if Ben has Cystic Fibrosis. Selected Answer: Respons e Feedbac k: Two tests that Dr. Johnson could use would be a snasal potential difference test, or a sweat test. With a nasal potential difference test the doctor will check the cells in his nose to see how well the salt is moving in and out of them. He can check the cells by using electrodes on the lining of the nose. If the results come back abnormal this could show positive for Cystic Fibrosis. The second test that can be done is a sweat test. The doctor will rub a special chemical that causes sweating and then will create a small electrical current on the area. The sweat will be wiped off on a cloth and taken for analyzing. Someone who has too much salt in their sweat can be diagnosed with Cystic Fibrosis. A positive diagnosis will require two positive results where the tests are done of different days.
