Family Nurse Practitioner Exam

What initial test is not required for suspected acute pancreatitis?

1. Electrolyte panel

2. Barium swallow

3. Serum amylase level

4. Serum lipase level

The correct answer is: Barium swallow

In the context of diagnosing suspected acute pancreatitis, the barium swallow is not required as an initial test. Acute pancreatitis is primarily diagnosed through clinical symptoms and specific laboratory tests, which help assess the function and structure of the pancreas. Testing serum amylase and lipase levels is essential, as both enzymes can indicate pancreatic inflammation; typically, serum lipase is more sensitive and specific for pancreatitis. An electrolyte panel can help to evaluate the patient's overall state and identify any imbalances that may arise from vomiting or other complications related to pancreatitis. In contrast, a barium swallow test is primarily used to examine the upper gastrointestinal tract, including the esophagus and stomach, and is not relevant for acute pancreatitis, as it does not provide information directly related to pancreatic function or inflammation. Thus, its omission from the initial assessment for suspected acute pancreatitis is appropriate.
