The nurse in the community health center teaches patient that hepatitis B is transmitted by:

A. A nosocomial infection is one that is acquired in a healthcare setting, such as a hospital. Given that Mary Jones had a Foley catheter inserted on the day of admission and developed symptoms of infection shortly thereafter, this indicates that the infection is likely related to her hospital stay.

B. Community-acquired infections occur outside of healthcare settings, so this does not apply since the infection arose after her hospital admission.

C. While the patient has an acute infection, the classification is more specifically defined by its origin (nosocomial in this case).

D. Since the patient is showing signs of infection (fever and high WBC), it is incorrect to say there is no infection.

A. Cancer is not a common cause of acute pancreatitis; it may cause chronic pancreatitis or complications in later stages.

B. While cystic fibrosis can lead to pancreatic damage, it is not the most prevalent cause of acute pancreatitis.

C. Autoimmunity can contribute to pancreatic conditions but is not the leading cause of acute pancreatitis.

D. Excess alcohol intake is a well-established and the most common cause of acute pancreatitis due to its toxic effects on pancreatic cells.
