An understanding of cells and cell behavior is a critically important component of disease diagnosis and treatment. But some diseases can be complex in nature, with a variety of factors and circumstances impacting their emergence and severity.
Effective disease analysis often requires an understanding that goes beyond isolated cell behavior. Genes, the environments in which cell processes operate, the impact of patient characteristics, and racial and ethnic variables all can have an important impact.
An understanding of the signals and symptoms of alterations in cellular processes is a critical step in the diagnosis and treatment of many diseases. For APRNs, this understanding can also help educate patients and guide them through their treatment plans.
In this Assignment, you examine a case study and analyze the symptoms presented. You identify cell, gene, and/or process elements that may be factors in the diagnosis, and you explain the implications to patient health.
Sample Answer
Case Study
A 50-year-old African American male presents with a 2-week history of fatigue, shortness of breath, and easy bruising. He has a history of hypertension and hyperlipidemia, but he has been otherwise healthy. On physical examination, he is found to have pallor, hepatosplenomegaly, and petechiae. His laboratory findings include a hemoglobin of 8.0 g/dL, a white blood cell count of 4,000/μL, and a platelet count of 10,000/μL.
Diagnosis
The patient’s presentation is consistent with acute myeloid leukemia (AML). AML is a cancer of the blood and bone marrow that is characterized by the overproduction of immature white blood cells. These immature white blood cells are not able to function properly, and they can crowd out normal blood cells, leading to anemia, neutropenia, and thrombocytopenia.
