Hypersensitivity: Type 3 - Examples {Ans: Rheumatoid arthritis: Antigen/antibodies are deposited in the joints Systemic Lupus Erythematosus (SLE)- very closely related to autoimmunity- antigen/antibodies deposit in organs that cause tissue damage}Folate Deficiency {Ans: Can cause megaloblastic anemia, Alcoholics can easily get folate deficiency Ferritin level normal Hgb low Hct low}NYHA Functional Classifications- It's all about the impact on the patient's activity caused by the HF symptoms: {Ans: -Stage I: Mild- no limitation of physical activity; Ordinary physical activity does not cause symptoms -Stage II: Mild- slight limitation of physical activity; comfortable at rest; Ordinary physical activity results in fatigue, palpitation, dyspnea or anginal pain. -Stage III: Moderate- marked decrease in physical activity; marked limitation of physical activity; comfortable at rest. Less than ordinary activity causes fatigue, palpitation, dyspnea or anginal pain. -Stage IV: Severe- inability to carry on any physical activity without discomfort. Symptoms of HF or the anginal syndrome may be present even at rest. If any physical activity undertaken, discomfort is increased.}Total Lung Capacity (TLC) {Ans: RV + FVC = TLC Normal range is 80-120% of predicted Obstructive: >120% (represents hyperinflation) Restrictive: <80%}Forced Vital Capacity (FVC) {Ans: Normal 80-120% The FVC measures the
