The role genetics plays in diseases
Scenario:
An 83-year-old resident of a skilled nursing facility presents to the emergency department with generalized edema of extremities and abdomen. History obtained from staff reveals the patient has a history of malabsorption syndrome and difficulty eating due to a lack of dentures. The patient has been diagnosed with protein malnutrition.
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.
What might be a characteristic influencing your response?
The scenario reflects this to be an unidentified race, so if this patient was African American would this create characteristics influenced by race? It may or may not just support your point with a citation.
In this elderly female, there are several contributing factors for her presenting with these symptoms.
Sample Answer
Here are the answers to your questions:
- Role of genetics in the disease: Genetics can play a role in protein malnutrition in a number of ways. For example, some people may have genetic mutations that make it difficult for them to absorb protein from food. Additionally, some people may have genetic conditions that increase their risk of developing malabsorption syndrome.
- Why the patient is presenting with the specific symptoms described: The patient is presenting with the specific symptoms described because of the protein malnutrition. Protein malnutrition can cause a number of problems, including edema, weakness, fatigue, and difficulty healing.
