December l Nursing2021 l 21Case presentation: CS is a 22-year-old White female with a history of asthma who presented to the ED with severe stabbing right lateral chest pain and shortness of breath. CS also reported extreme fatigue for several months after a viral upper respiratory infection and pneumonia. CS denied recent weight loss. She was adopted from Russia and is not aware of her family history.She reported waking up early in the morning due to a "constant stabbing pain" that increased with deep inspiration and expiration. She rated the pain as a 9/0-10 on the numerical pain rating scale, and said that it aggravated with exertion and would not go away.Upon arrival in the ED, CS was tachycardic (HR: 120/minute) and tachypneic (RR: 22/minute). SpO2 was 91% on room air. Temperature and BP were within the normal range. CS received a combination of the beta2adrenergic bronchodilator, and the anticholinergic bronchodilator, ipratropium bromide, via nebulizer.Lab data revealed a positive D-dimer, and consequently, CS was initially thought to have a pulmonary embolism. 1 Her serum C-reactive protein concentration was elevated at 7.0 mg/dL (normal, <1 mg/dL). 1 Other lab values, including HIV testing, liver panel, cyclic citrullinated peptide antibody, and rheumatoid factor, were all negative.Electrocardiography showed sinus tachycardia with nonspecific T-wave abnormalities. A chest radiograph demonstrated abnormalities that necessitated high-resolution computed tomography (HRCT) of the chest with contrast. The HRCT report showed pulmonary masses that may be malignant, so CS was admitted to the hospital for further diagnostic testing. CS was subsequently diagnosed with sarcoidosis.Sarcoidosis is a multisystem inflammatory disease that leads to the formation of abnormal masses or nodules called granulomas in various organs. 2,3 This article discusses a case study on sarcoidosis to help nurses have a better understanding of the overall disorder, recognize diagnosis and treatment options, and provide holistic care to patients with this diagnosis.
