To prevent the spread of hepatitis A virus (HAV) infection, the nurse is especially careful when:
Changing an IV
Disposing of food trays
Emptying bed pans
Taking an oral temperature
The Correct Answer is C
A. Changing an IV: This procedure involves standard precautions to avoid bloodborne infections, not primarily fecal-oral infections like hepatitis A. It is more relevant to viruses such as hepatitis B and C.
B. Disposing of food trays: While hygiene in food service is important, the nurse’s direct role in disposing of trays does not significantly contribute to HAV prevention. HAV is transmitted primarily through the fecal-oral route rather than leftover food on trays.
C. Emptying bed pans: Hepatitis A is spread via the fecal-oral route. Handling feces, especially without strict hand hygiene and appropriate protective equipment, poses a high risk for transmission. Therefore, careful attention is needed during this activity to prevent spread.
D. Taking an oral temperature: This involves mucosal contact but carries minimal risk of spreading hepatitis A, especially when using disposable covers and practicing standard precautions. It is not a primary concern for fecal-oral transmission.

Correct Answer is A
Explanation
A. The Somogyi effect results from an excessive insulin dose causing hypoglycemia overnight, triggering a rebound hyperglycemia via release of glucagon, cortisol, and growth hormone. In contrast, the dawn phenomenon is a natural early morning rise in blood glucose due to circadian increases in cortisol and growth hormone without preceding hypoglycemia.
B. The Somogyi effect happens only in type 2 diabetes, while the dawn phenomenon happens only in type 1 diabetes: Both effects can occur in either type 1 or type 2 diabetes depending on insulin therapy and individual physiology.
C. Both the Somogyi effect and the dawn phenomenon occur due to nighttime hyperglycemia: The Somogyi effect starts with nighttime hypoglycemia, not hyperglycemia, while the dawn phenomenon involves a gradual early morning rise in glucose levels.
D. The Somogyi effect is caused by insufficient insulin at night, while the dawn phenomenon is caused by excessive nighttime insulin: The Somogyi effect is caused by excessive insulin leading to hypoglycemia, not insufficient insulin. The dawn phenomenon is unrelated to nighttime insulin dosing and is caused by hormonal changes.
Correct Answer is ["A","B","C","D","E"]
Explanation
A. Secretions include amylase: Amylase is a digestive enzyme secreted by the pancreas that helps break down carbohydrates. Elevated serum amylase is a common diagnostic marker in acute pancreatitis.
B. Contains proteolytic enzymes that break down dietary proteins: The pancreas produces proteolytic enzymes like trypsin and chymotrypsin, which digest proteins in the small intestine under normal conditions.
C. Pancreatic enzymes auto-digest pancreatic cells and tissue: In acute pancreatitis, premature activation of these enzymes inside the pancreas leads to self-digestion and inflammation of pancreatic tissue.
D. A reversible inflammatory process: Acute pancreatitis is typically reversible with prompt treatment, unlike chronic pancreatitis which involves permanent structural damage and functional loss.
E. Cardinal manifestation is abdominal pain – could be midabdominal, could be epigastric: Severe abdominal pain is the hallmark symptom, commonly located in the epigastric or midabdominal region and may radiate to the back.
