The nurse is caring for a patient who has a venous leg ulcer. The patient asks why these ulcers occur. What will the nurse explain as the cause for the development of venous ulcers?

A. Injection of drugs:
Hepatitis E is not primarily spread through the injection of drugs. While injection drug use can increase the risk of hepatitis B and C transmission, hepatitis E is typically spread through the fecal-oral route, often via contaminated water or food.

B. Semen:
Hepatitis E is primarily transmitted via the fecal-oral route and is not commonly spread through semen. Sexual transmission of hepatitis E is rare compared to other types of viral hepatitis, and the primary mode of transmission is ingestion of contaminated food or water.

C. Fecal-oral:
The fecal-oral route is the primary mode of transmission for hepatitis E. This means that the virus is spread through ingestion of food or water contaminated with fecal matter containing the virus. Poor sanitation and hygiene practices are common risk factors for hepatitis E transmission.

D. Blood:
Unlike hepatitis B and C, hepatitis E is not primarily transmitted through blood exposure. While transmission through blood transfusions or organ transplants has been reported in some cases, the main mode of transmission for hepatitis E is ingestion of contaminated food or water.

A. "Your veins are not functioning properly. Lack of venous blood volume causes these ulcers": While venous insufficiency contributes to the development of venous ulcers, the primary issue is not necessarily a lack of venous blood volume but rather impaired venous return due to valve dysfunction.

B. "Your veins are weaker and blood is not moving up as it should. The congestion in your veins causes the ulcers to form.": This explanation accurately describes the pathophysiology of venous ulcers. Venous insufficiency leads to venous congestion, which causes increased pressure in the veins of the lower extremities. This pressure can result in the breakdown of skin and the formation of ulcers, typically around the ankles.

C. "Because the veins are not working properly, there is not enough oxygen going to the skin of your legs.": While venous insufficiency can affect tissue oxygenation to some extent, the primary mechanism leading to venous ulcers is venous congestion and increased pressure in the lower extremities, rather than insufficient oxygen delivery.

D. "Your veins clogged so the body causes the arteries to swell and the excess oxygen in the blood causes the ulcers.": This explanation does not accurately describe the pathophysiology of venous ulcers. Venous ulcers result from impaired venous return and venous congestion, not arterial swelling or excess oxygen in the blood.
