Pathophysiology & Clinical Findings of the Disease
1. Identify the correct hypersensitivity reaction:
Based on the symptoms displayed by the patient, it is highly probable that they are
experiencing allergic rhinitis triggered by allergens in their home environment. The study
conducted by Seidman et al. (2015) reveals that the prevalence of Allergic Rhinitis (AR) in the
US is estimated to be around one in six people, which means that it is prevalent, ranking as the
fifth most common ailment in the country.
2. Explain the pathophysiology associated with the chosen hypersensitivity reaction:
Allergic rhinitis, commonly referred to as hay fever, involves inflammation of the nasal
passages triggered by an immune response to allergens like pollen, dust, and pet dander.
Manifestations include nasal congestion, sneezing, itching, and a runny nose. Prolonged
exposure to allergens can intensify symptoms due to sustained inflammation. This immune
response is mediated by immunoglobulin E (IgE) and affects the nasal mucous membranes
upon exposure to inhaled allergens. Predominant symptoms encompass nasal congestion,
irritation, rhinorrhea (anterior or postnasal drip), and sneezing. Allergic rhinitis may manifest as
either sporadic or chronic symptoms (Seidman et al., 2015).
3. Identify at least three subjective findings from the case:
Gathering subjective data from patients and their families is crucial to healthcare. This
information can provide valuable cues about a patient's needs and help identify areas where
assistance is required. The data is obtained directly from the patient, so it is considered a
symptom and cannot be ignored (Libretexts, 2022). According to the patient's description, her
subjective findings are as follows: She was in good health until 12 months ago, when she
