Alterations in Cellular Processes Discussion

At its core, pathology is the study of disease. Diseases occur for many reasons. But some, such as cystic fibrosis and Parkinson’s Disease, occur because of alterations that prevent cells from functioning normally.

Understanding of signals and symptoms of alterations in cellular processes is a critical step in diagnosis and treatment of many diseases. For the Advanced Practice Registered Nurse (APRN), this understanding can also help educate patients and guide them through their treatment plans.

For this Discussion, you examine a case study and explain the disease that is suggested. You examine the symptoms reported and explain the cells that are involved and potential alterations and impacts. 

To prepare:

  • By Day 1 of this week, you will be assigned to a specific scenario for this Discussion. Please see the “Course Announcements” section of the classroom for your assignment from your Instructor.
  •  

Post an explanation of the disease highlighted in the scenario you were provided. Include the following in your explanation:

  • The role genetics plays in the disease.
  • Why the patient is presenting with the specific symptoms described.
  • The physiologic response to the stimulus presented in the scenario and why you think this response occurred.
  • The cells that are involved in this process.
  • How another characteristic (e.g., gender, genetics) would change your response.

Week 1 Scenario:  A mother brings her 6-month-old daughter to the HCP for evaluation of possible colic. The mother says the baby has had many episodes of crying after eating and, despite having a good appetite, is not gaining weight. The mother says the baby’s belly “gets all swollen sometimes.” The mother says the baby tastes “salty” when the mother kisses the baby. Further work up reveals a diagnosis of cystic fibrosis. The mother relates that her 23-month-old son has had multiple episodes of “chest congestion” and was hospitalized once for pneumonia. The mother wants to know what cystic fibrosis is and she also wants to know if she should have any more children.
