A nurse provides teaching for a patient who is newly diagnosed with Parkinson's disease. Which statement by the patient indicates understanding of the drug therapy for this disease?

Choice A reason: Hepatitis B is a viral infection that is commonly transmitted through sexual contact, as well as through exposure to infected blood or body fluids. It is highly infectious and can be spread through unprotected sex, sharing needles, or from an infected mother to her baby during childbirth. Hepatitis B can cause both acute and chronic liver disease, and vaccination is the most effective way to prevent infection.

Choice B reason: Hepatitis C is primarily transmitted through direct blood-to-blood contact. While it is less commonly spread through sexual contact compared to Hepatitis B, it is possible, particularly among individuals with multiple sexual partners or those who engage in high-risk sexual behaviors. Hepatitis C often becomes chronic, leading to serious liver damage over time. There is no vaccine for Hepatitis C, but antiviral medications can effectively cure the infection in most cases.

Choice C reason: Hepatitis E is primarily transmitted through the fecal-oral route, usually by consuming contaminated water or food. It is not commonly transmitted sexually. Hepatitis E is more prevalent in regions with poor sanitation, and it typically causes acute liver disease, which generally resolves on its own in most healthy individuals. Prevention includes good sanitation practices and proper hand hygiene.

Choice D reason: Hepatitis A is also transmitted through the fecal-oral route, primarily by ingesting contaminated food or water. It is not typically associated with sexual transmission. Hepatitis A causes acute liver disease, which usually resolves without long-term liver damage. Vaccination is available and effective in preventing Hepatitis A infection.

Choice A reason: Abdominal pain and rectal bleeding are not the primary signs of a bowel obstruction. Rectal bleeding could be indicative of other gastrointestinal issues such as hemorrhoids, diverticulosis, or colorectal cancer. While abdominal pain is a symptom of bowel obstruction, rectal bleeding is not typically associated with it.

Choice B reason: The primary symptoms of bowel obstruction include abdominal distention, pain, inability to have a bowel movement, and nausea/vomiting. When a bowel obstruction occurs, the normal movement of intestinal contents is blocked, leading to a buildup of contents and gas. This results in abdominal distention and pain. The blockage also prevents the passage of stool and gas, causing constipation or inability to have a bowel movement. Nausea and vomiting are common as the digestive system tries to expel the contents that cannot pass through the obstruction.

Choice C reason: Dehydration, back pain, and fever are not the hallmark symptoms of bowel obstruction. While dehydration can occur due to vomiting and reduced intake, back pain is not commonly associated with bowel obstruction. Fever may indicate an infection or other complications but is not a primary symptom of bowel obstruction.

Choice D reason: Diarrhea and excessive thirst are not typical signs of bowel obstruction. In fact, bowel obstruction usually leads to constipation or the inability to pass stool rather than diarrhea. Excessive thirst could be a sign of dehydration but is not specific to bowel obstruction.
