Disease process

examine an assigned disease process and determine which disease process explored in the discussion Janessa, the client, is experiencing. Follow the instructions below and your faculty member will reveal which disease process Janessa is experiencing at the end of the discussion week.

Step 1: Review the following client scenario:

Janessa, a 41-year-old female client, presents to the NP complaining of shortness of breath, weakness, and dizziness for “about a month.” She denies having a cough or recent illness. She has a history of endometriosis, and her physical assessment reveals her lungs are clear to auscultation bilaterally, and her mucous membranes are pale.

Step 2: Review your assigned disease process from the chart below. Your assigned disease process is based on the first letter of your last name.

Last Name Disease Process

A – H Condition: Anemia

I – P Condition: Heart Failure

Q – Z Condition: Asthma

Step 3: Review your assigned disease process and answer the discussion prompts below with explanation and detail, providing complete references for all citations.

Step 4: Reply to a peer with a different assigned condition.

Include the following sections:

Application of Course Knowledge: Answer all questions/criteria with explanations and detail.

Discuss the underlying pathophysiological mechanisms of your assigned disease process. Which clinical manifestations observed in Janessa’s case could be explained by the pathophysiological mechanisms?
Analyze Janessa’s clinical manifestations in the context of your assigned disease process. Do these findings support a diagnosis of your assigned disease process? Why or why not?
Identify and justify the diagnostic tests (including labs, imaging, or other diagnostic tests) that would be most appropriate for investigating a diagnosis of your assigned disease process in Janessa. What could the results of these tests look like in your assigned disease process?
Compare and contrast your response with a peer who was assigned a different condition. Does their condition fit Janessa’s case? Why or why not?

• Describe the role of the EEOC in the practice of I/O psychology and three different laws that are enforced by the EEOC.
• Describe two different types of discrimination prohibited by the laws enforced by EEOC and at least three best practices you would suggest for ensuring equity in the workplace.
• Suppose you find yourself in an elevator with the CEO of a Fortune 500 company that you admire greatly. You strike up a casual conversation that suddenly turns to the topic of discrimination in the workplace, and you quickly realize that the CEO has no understanding of I/O psychology or I/O psychologists’ roles in addressing these concerns. One day you hope to begin your I/O career at this company or one similar to it. Therefore, you decide to give a quick elevator speech on I/O psychology and its role in best practices to address discrimination and inequity in the workplace. What would you say?

Application of Course Knowledge:

1. Discuss the underlying pathophysiological mechanisms of Anemia. Which clinical manifestations observed in Janessa’s case could be explained by the pathophysiological mechanisms?

Anemia is a condition characterized by a reduction in the number of red blood cells (RBCs) or the amount of hemoglobin within these cells, leading to a decreased oxygen-carrying capacity of the blood. The core pathophysiological mechanism is a mismatch between the body’s oxygen demand and the blood’s ability to supply it. This can stem from three primary causes: decreased RBC production (e.g., nutritional deficiencies like iron, B12, folate; bone marrow suppression; chronic kidney disease), increased RBC destruction (hemolysis), or blood loss (acute or chronic). Regardless of the cause, the reduced oxygen delivery to tissues triggers compensatory mechanisms. The body attempts to increase oxygen supply by increasing cardiac output (heart rate and stroke volume), redistributing blood flow to vital organs, and increasing respiratory rate and depth. These compensatory efforts are what lead to many of the observable clinical manifestations.

In Janessa’s case, several clinical manifestations can be directly explained by the underlying pathophysiology of anemia. Her primary complaint of shortness of breath is a classic symptom. With fewer RBCs or less hemoglobin, less oxygen reaches the tissues, including the respiratory muscles and brain, leading to dyspnea as the body tries to compensate by breathing faster and deeper. The weakness she experiences is also directly linked to insufficient oxygen supply to muscles, impairing their ability to generate energy (ATP) efficiently. Similarly, dizziness is a common symptom of anemia. This occurs because the brain is highly sensitive to oxygen

deprivation; reduced cerebral oxygen perfusion can cause lightheadedness or dizziness. Her pale mucous membranes are a direct visual sign of reduced hemoglobin concentration in the blood circulating through the capillaries, making the tissues appear less red. Her history of endometriosis is also relevant, as it can cause chronic blood loss through heavy menstrual bleeding, which is a common cause of iron-deficiency anemia, a form of anemia due to decreased RBC production.

2. Analyze Janessa’s clinical manifestations in the context of Anemia. Do these findings support a diagnosis of Anemia? Why or why not?

Janessa’s clinical manifestations strongly support a potential diagnosis of anemia. Her primary complaints of shortness of breath, weakness, and dizziness for “about a month” are classic symptoms directly attributable to the reduced oxygen-carrying capacity characteristic of anemia. The fact that her lungs are clear to auscultation bilaterally is significant because it suggests her shortness of breath is unlikely due to primary pulmonary disease (like asthma or pneumonia), further pointing towards a systemic issue like anemia affecting oxygen transport. Her pale mucous membranes are a very specific and observable physical sign of anemia, indicating low hemoglobin levels. Furthermore, her history of endometriosis provides a plausible etiological link. Endometriosis often leads to menorrhagia (heavy menstrual bleeding) or other forms of chronic blood loss, which is the most common cause of iron deficiency anemia in menstruating women. The gradual onset of symptoms (“about a month”) is also consistent with chronic blood loss anemia, where the body’s compensatory mechanisms are slowly overwhelmed over time. While these findings are highly suggestive, a definitive diagnosis requires laboratory confirmation, but the clinical picture aligns very well with anemia.

3. Identify and justify the diagnostic tests (including labs, imaging, or other diagnostic tests) that would be most appropriate for investigating a diagnosis of Anemia in Janessa. What could the results of these tests look like in Anemia?

To investigate a diagnosis of anemia in Janessa, a systematic approach using specific diagnostic tests is essential to confirm the diagnosis, determine the type of anemia, and identify its underlying cause.

Complete Blood Count (CBC) with Differential: This is the foundational test for anemia.
- Justification: It directly measures hemoglobin (Hb), hematocrit (Hct), red blood cell (RBC) count, and provides RBC indices, which are crucial for diagnosing and classifying anemia.
