The nursing diagnosis of pleural effusion focuses on explaining some of the symptoms of pleural effusion. For example, patients with pleural effusion often experience shortness of breath after activity, chest tightness, shortness of breath, and in severe cases, dyspnea. Symptoms like tuberculous pleurisy may also present with fever, malaise, cough, and chest pain. Nursing diagnosis is to explain symptoms like shortness of breath, which is caused by increased amount of pleural fluid and pressure on the heart and lungs, which causes shortness of breath after activity. Symptoms like fever, malaise, cough, and chest pain are due to symptoms of tuberculosis toxicity after tuberculosis infection. Chest pain and cough are mainly caused by pleural reaction. The above is the nursing diagnosis.
