Pathophisiology Assignment. Instructions

· This week’s case study will introduce concepts related to the pulmonary system and shock states. Read the scenario and thoroughly complete the questions. Some of the answers will be short answers and may not require a lot of details. For example: what is the most common organism to cause a hospital acquired infection? The answer is pseudomonas aeruginosa. Answers to questions that relate to the pathogenesis of a disease must include specific details on the process. For example: How does hypoxia lead to cellular injury? Simply writing that a lack of blood flow, causes a lack of oxygen available to the cell and the cell cannot function without oxygen is not sufficient. This type of response is NOT reflective of an advanced understanding of the concept or graduate level work. This answer should discuss the cascade of events leading to the lack of oxygen and how it specifically impairs cellular function. All answers to these type of questions should address the effects at the cellular level, then the effects on the organ and then the body as a whole. Additionally describing the normal anatomical and/or physiologic processes underlying the pathogenesis will be necessary to thoroughly answer the question.

It is very likely that you will need to reference multiple sources to answer the questions thoroughly. Your text book will not necessarily have all the answers. Only professional sources may be used to complete the assignment. These include text books, primary and secondary journal articles from peer reviewed journals, government and university websites, and publications from professional societies who establish disease management guidelines and recommendations. Sources such as Wikipedia or other generic websites are not considered professional references and should not be used to complete the case studies.

History of Present Illness: Mrs. X is 73-year-old Caucasian female who was admitted to the general surgery service 3 days ago for a leaking j-tube which was surgically replaced 2 days ago.

· an “Original sequence” of mRNA that has been translated properly into its corresponding amino acid sequence

· a “Mutated sequence” that is blank

· a “Mutation Rules” block of information

4. Your task is to read the information in the “Mutation Rules” area and then apply the information to completing the “Mutated sequence” of mRNA and protein. To do this, you must:

· read the “Mutation Rule”

· look at the “Original sequence” of mRNA given

· determine the “Mutated sequence” of mRNA bases after applying the information presented in the “Mutation Rule”

· determine the “Mutated sequence” of protein (amino acids) translated from the mRNA sequence you just created using the “Genetic Code Chart”

5. Please complete this information in the area below BEFORE actually completing the virtual activity; you can then refer to it to help make the correct selections at each step. Remember to use the “Genetic Code Chart” to determine the protein sequence:

“Mutation Rule” states: ___________________________________________

Original Sequence:

mRNA

                                               
               

Protein

Mutated Sequence:

mRNA

                                                 
               

Protein

6. Once you have filled in the information above, drag the correct nucleotides

to their position in the “Mutated sequence” of mRNA. Then drag the corresponding amino acids into place in the “Mutated sequence” of protein. When you are finished, click “Check”. A message will appear in the open box at the bottom of the page indicating whether your answer needs to be corrected. You may repeat this entire activity by clicking “Mutate”.

7. Please finish this exercise by opening the “Journal” link at the bottom of the page and answering the questions.
