A nurse admits a patient to the emergency department who reports nausea and vomiting that worsens when he lies down.
Antacids do not help.
The provider suspects acute pancreatitis.
Which of the following laboratory test results should the nurse expect to see?
Decreased serum lipase.
Increased serum calcium.
Increased serum amylase.
Decreased WBC.
The Correct Answer is C
Choice C rationale
In the context of suspected acute pancreatitis, an increase in serum amylase is one of the key laboratory findings. Pancreatitis is associated with inflammation of the pancreas, which can result in the release of digestive enzymes such as amylase and lipase into the bloodstream.
Therefore, elevated levels of these enzymes are often used as markers for acute pancreatitis.
Choice A rationale
Decreased serum lipase is not typically associated with acute pancreatitis. In fact, an increase in serum lipase is more commonly seen in acute pancreatitis. Lipase is a digestive enzyme produced by the pancreas, and its levels in the blood can rise when the pancreas is inflamed.
Choice B rationale
Increased serum calcium is not typically associated with acute pancreatitis. While hypercalcemia, or high calcium levels, can be a cause of pancreatitis, it is not a typical finding in the blood tests of patients with acute pancreatitis.
Choice D rationale
Decreased white blood cell (WBC) count is not typically associated with acute pancreatitis. In fact, an increase in WBC count can sometimes be seen in acute pancreatitis due to the body’s inflammatory response to the condition. Hypothyroidism Explore

Correct Answer is B
Explanation
Choice A rationale
Consuming a large amount of alcohol at one time can lead to liver damage and other health problems, but it does not directly cause hepatitis C infection. Hepatitis C is a viral infection that primarily spreads through contact with infected blood.
Choice B rationale
Coming into contact with infected blood, such as from a dirty needle, can indeed cause you to become infected with hepatitis C. This is one of the most common ways the virus is transmitted, particularly through sharing needles or other equipment to inject drugs.
Choice C rationale
Hepatitis C does not typically spread through contact with an infected person’s bodily fluids such as saliva. The virus is primarily bloodborne, meaning it spreads through direct contact with infected blood.
Choice D rationale
Eating contaminated food or water from an infected source does not cause hepatitis C. The virus does not spread through food or water, or by casual contact.
