Which of the following is a common risk factor for the development of pancreatic cancer?
Viral hepatitis
High fiber diet
Chronic pancreatitis
Regular exercise
The Correct Answer is C
A. Viral hepatitis: Hepatitis B and C are risk factors for liver cancer, not pancreatic cancer. There is no strong link between hepatitis and pancreatic cancer.
B. High-fiber diet: A high-fiber diet is protective against colorectal cancer, not a risk factor for pancreatic cancer.
C. Chronic pancreatitis: Chronic inflammation of the pancreas increases the risk of pancreatic cancer by causing long-term cellular damage and mutations.
D. Regular exercise: Exercise reduces the risk of many cancers, including pancreatic cancer. Sedentary lifestyles and obesity increase the risk.

Explanation
A. Dysphagia: Dysphagia (difficulty swallowing) is unrelated to diverticulitis; it is more common in esophageal disorders.
B. Crohn’s disease: Crohn’s disease is a separate chronic inflammatory bowel disease (IBD), not a complication of diverticulitis.
C. Peritonitis: Peritonitis is a life-threatening complication of diverticulitis. If an inflamed diverticulum perforates, stool and bacteria spill into the peritoneal cavity, causing severe abdominal pain, rigidity, fever, and tachycardia.

Correct Answer is B
Explanation
A. Contact: Hepatitis C is transmitted primarily through blood, not through direct contact (e.g., touching contaminated surfaces). Contact precautions are not necessary unless there are open wounds or excessive body fluid exposure.
B. Standard: Hepatitis C is a bloodborne virus transmitted through exposure to infected blood (e.g., needlestick injuries, IV drug use). Standard precautions, including hand hygiene, glove use, and proper handling of sharps, are sufficient.
C. Droplet: Hepatitis C is not spread via respiratory droplets (e.g., sneezing, coughing). Droplet precautions are unnecessary.
D. Airborne: Hepatitis C is not transmitted via airborne particles (e.g., tuberculosis, measles). Airborne precautions are unnecessary.
