This nursing assignment delves into the analysis of sickle cell disease, focusing on the detrimental effects of smoking and alcohol consumption on patients. The assignment highlights how tobacco reduces oxygen flow, leading to lung infections, and increases the risk of acute chest syndrome, pneumonia, pulmonary hypertension, and strokes. It also explains how smoking constricts blood vessels, exacerbating pain crises, and how nicotine further reduces oxygen levels. The analysis extends to the dangers of marijuana use, which can increase cancer risks, and the adverse effects of alcohol, including dehydration and the triggering of pain crises due to fluid loss. The assignment references multiple studies to support its claims and underscores the importance of avoiding smoking and alcohol for individuals with sickle cell disease.
