Case Study 1: Pulmonary Function

Posted: April 4th, 2019

Pulmonary Function:
D.R. is a 27-year-old man, who presents to the nurse practitioner at the Family Care Clinic complaining of increasing SOB, wheezing, fatigue, cough, stuffy nose, watery eyes, and postnasal drainage—all of which began four days ago. Three days ago, he began monitoring his peak flow rates several times a day. His peak flow rates have ranged from 65-70% of his regular baseline with nighttime symptoms for 3 nights on the last week and often have been at the lower limit of that range in the morning. Three days ago, he also began to self-treat with frequent albuterol nebulizer therapy. He reports that usually his albuterol inhaler provides him with relief from his asthma symptoms, but this is no longer enough treatment for this asthmatic episode.

Case Study 1: Pulmonary Function

According to the case study information, the severity of D.R.’s asthma attack can be classified as moderate persistent asthma. The symptoms he presents with, including increasing shortness of breath (SOB), wheezing, fatigue, cough, stuffy nose, watery eyes, and postnasal drainage, indicate an exacerbation of his asthma. The fact that his peak flow rates have ranged from 65-70% of his regular baseline suggests moderate airflow limitation. The nighttime symptoms and the need for frequent albuterol nebulizer therapy further indicate the worsening of his asthma.

The most common triggers for asthma in any given patient include:

Allergens: Such as pollen, dust mites, pet dander, and mold spores.
Irritants: Including cigarette smoke, air pollution, strong odors, and chemicals.
Respiratory infections: Viral infections, such as common cold or flu, can trigger asthma symptoms.
Exercise: Physical exertion or exercise-induced asthma can be a trigger.
Weather changes: Cold air, humidity, or changes in temperature can provoke asthma.
Stress and emotions: Emotional stress can trigger asthma symptoms.
In the case of D.R., it is likely that allergens, such as pollen or dust mites, could be contributing to his symptoms as he presents with stuffy nose, watery eyes, and postnasal drainage. It is also possible that a respiratory infection could have triggered his current asthma exacerbation.

The etiology of D.R. being an asthmatic patient can be attributed to various factors, including:
Genetic predisposition: Asthma tends to run in families, suggesting a genetic component.
Environmental factors: Exposure to allergens, pollutants, and respiratory infections can contribute to the development of asthma.
Immunological factors: Abnormal immune responses, including inflammation and hypersensitivity reactions, play a role in asthma.
Airway hyperresponsiveness: Asthma involves increased sensitivity of the airways to various triggers, leading to bronchoconstriction and inflammation.
Allergic reactions: Many individuals with asthma have allergies, and allergic reactions can trigger asthma symptoms.
It is important to note that asthma is a complex disease with multiple potential causes, and individual cases may have varying etiologies. Further evaluation and assessment of D.R.’s medical history, family history, and environmental exposures would provide a more comprehensive understanding of his specific asthma triggers and etiological factors.

Case Study 2: Fluid, Electrolyte, and Acid-Base Homeostasis

Based on Ms. Brown’s admission laboratory values, she has hyperglycemia (high blood glucose) indicating uncontrolled diabetes mellitus. Additionally, her serum sodium (Na+) level is elevated (hypernatremia), her serum potassium (K+) level is elevated (hyperkalemia), and her serum chloride (Cl–) level is elevated (hyperchloremia). These electrolyte imbalances suggest a state of dehydration and fluid loss.

Signs and symptoms of water and electrolyte imbalances:

Hypernatremia: Thirst, dry mouth, decreased urine output, restlessness, confusion, seizures, and coma.
Hyperkalemia: Weakness, fatigue, palpitations, arrhythmias, muscle cramps, and potentially life-threatening cardiac dysrhythmias.
Hyperchloremia: Deep, rapid breathing (Kussmaul respirations), weakness, lethargy, hypertension, and metabolic acidosis.
With Ms. Brown’s elevated potassium level (hyperkalemia), she may exhibit muscle weakness, fatigue, palpitations, and potentially cardiac arrhythmias. These symptoms can be attributed to the effect of elevated potassium
