10 / 10 pts
Define secondary prevention and give an example:
Your Answer:
It is one of three categories in disease prevention. It aims to detect and treat disease early, while the disease is asymptomatic and curable. An example is an annual Pap smear.
Secondary prevention aims to detect and treat disease early, usually while the disease is asymptomatic and curable. Some examples include annual Pap smears to detect early cervical cancer, encouraging smoking cessation, checking blood pressure and cholesterol, and colonoscopy screening.
Question 15
10 / 10 pts
Compare and contrast the two types of gangrenous necrosis. Your Answer:
2 types are dry and moist. In dry gangrenous, the affected tissue is dehydrated, shrinks back and becomes dark brown or black in color. THe spread of dry is slow. In wet, the affected area is cold, swollen, with no pulse. The skin is moist, black, and distended. Small blisters form and as liquefaction occurs, foul ordor emerges. The spread of wet gangrenous is rapid.
In dry gangrene the affected tissue becomes dry and shrinks, the skin wrinkles, and its color changes to dark brown or black. The spread of dry gangrene is slow. It results from a cut off in arterial blood supply and is a form of coagulation necrosis. In wet gangrene, the affected area is cold, swollen, and pulseless. The skin is moist, black, and under tension. Blebs form on the surface, liquefaction occurs, and a foul odor is caused by bacterial action. The spread of tissue damage is rapid.
Question 16
10 / 10 pts
Explain what necrosis is and give an example and description of one type of necrosis. Your Answer:
Necrosis is cell death in tissue or organ that is still part of a living person. An example of a type of necrosis is coagulative necrosis. This results from a sudden cutoff of the blood supply to an organ, such as the heart.
Necrosis refers to cell death in an organ or tissues that is still part of a living person. It often interferes with cell replacement and tissue regeneration. Coagulative necrosis results most often from a sudden cutoff of blood supply to an organ (ischemia), particularly the heart and kidney. Liquefactive necrosis occurs when some of the cells die but their catalytic enzymes are not destroyed. It is commonly seen with brain infarcts or abscesses. Caseous necrosis occurs as part of granulomatous inflammation and is most often associated with tuberculosis.
Gangrenous necrosis most often affects the lower extremities or bowel and is secondary to vascular occlusion. The term gangrene is applied when a considerable mass of tissue undergoes necrosis. In dry gangrene the affected tissue becomes dry and shrinks, the skin wrinkles, and its color changes to dark brown or black. The spread of dry gangrene is slow. It results from a cut off in arterial blood supply and is a form of coagulation necrosis. In wet gangrene, the affected area is cold, swollen, and pulseless. The skin is moist, black, and under tension. Blebs form on the surface,
liquefaction occurs, and a foul odor is caused by bacterial action. The spread of tissue damage is rapid.
