NR 507 Week 3 Discussion; Pathophysiology of Anemia and Asthma

• Weakness and Shortness of Breath: Common reactions to the body's decreased oxygen supply. These clinical signs, combined with her history of endometriosis (condition often linked to chronic blood loss) point toward anemia. While the symptoms are clear, additional testing is required to identify the exact cause or type. 3- 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? Diagnostic testing should focus on determining whether an anemia is present and then identifying the underlying etiology. Basic assays (complete blood count, reticulocyte count, and blood smear) will be reviewed first, then iron and B12 and folate levels (Cascio & DeLoughery, 2017).

How does the underlying pathophysiology of asthma contribute to its characteristic signs and symptoms, and how do these mechanisms guide the pharmacological and non- pharmacological treatment strategies used in its management? Asthma is a chronic inflammatory disease, characterized by symptoms like wheezing, chest tightness, coughing, and shortness of breath, resulting from factors including airway inflammation, bronchoconstriction, hyperresponsiveness (Hussain & Liu, 2024). The primary symptoms of asthma stem from three core physical changes: • Bronchoconstriction (Airway Tightening): When exposed to triggers, the muscles encircling the lungs' breathing tubes contract. This rapid squeezing narrows the internal space (the lumen), causing the classic "whistling" sound of wheezing as air struggles to pass through and a heavy sensation of chest tightness. • Inflammation (Swelling): The inner lining of these tubes becomes red and swollen, further reducing the space available for airflow. • Mucus Production: Excess, thick liquid is released into the already narrowed passages, which can lead to "mucus plugs" and a persistent cough as the body tries to clear the blockage. Asthma management is essentially a targeted response to the three physical ways the body overreacts to triggers. By understanding these mechanisms, treatments or prevention can be divided into pharmacological and non-pharmacological strategies. 1. Pharmacological Strategies (Medications) Medications are designed to reverse the three core physical changes: tightening, swelling, and clogging. • Targeting Bronchoconstriction: • Mechanism: Rapid, shallow breathing during an attack can worsen the sensation of chest tightness. • Strategy: Methods like pursed-lip breathing help maintain positive pressure in the airways, keeping them open longer and reducing the "work" of breathing. • Weight & Nutrition Management: • Mechanism: Obesity can physically compress the lungs and create systemic inflammation
