A nurse is caring for a client suspected to have cholecystitis. Which of the following diagnostic tests should the nurse anticipate as the first-line imaging study to confirm the diagnosis?
Abdominal computed tomography (CT) scan
Magnetic resonance imaging (MRI) of the gallbladder
Abdominal ultrasound
Endoscopic retrograde cholangiopancreatography (ERCP)
The Correct Answer is C
Choice A reason:
Abdominal CT scan can provide detailed images, but it is not typically the first-line imaging study for diagnosing cholecystitis. It may be used if complications are suspected.
Choice B reason:
MRI of the gallbladder can provide high-resolution images, but it is not the first-line imaging study for diagnosing cholecystitis.
Choice C reason:
This statement is correct. Abdominal ultrasound is the first-line imaging study for diagnosing cholecystitis. It can visualize the gallbladder, detect gallstones, and assess for signs of inflammation, such as gallbladder wall thickening and pericholecystic fluid.
Choice D reason:
ERCP is an invasive procedure used to visualize the biliary and pancreatic ducts, but it is not typically used as a first-line diagnostic test for cholecystitis.

Correct Answer is C
Explanation
Choice A reason:
Fasting for 12 hours before an abdominal ultrasound is not necessary. Abdominal ultrasound does not require an empty stomach.
Choice B reason:
Drinking water is not typically restricted before an abdominal ultrasound. In fact, drinking water can improve image quality in some cases.
Choice C reason:
This statement is correct. There are no special preparations required for an abdominal ultrasound. The procedure is non-invasive and does not involve any special preparation or fasting.
Choice D reason:
Avoiding pain medications is not necessary before an abdominal ultrasound. The client can continue taking prescribed medications as usual.
Correct Answer is B
Explanation
Choice A reason:
Antibiotics do not directly heal the ulcer or reduce stomach acid production. They are prescribed specifically to treat Helicobacter pylori (H. pylori) infection, a common cause of peptic ulcers.
Choice B reason:
This statement is correct. Antibiotics are prescribed to treat H. pylori infection, which is a major cause of peptic ulcers. By eliminating the bacterial infection, the ulcer has a better chance of healing and preventing recurrence.
Choice C reason:
Antibiotics do not promote blood clotting or reduce the risk of bleeding from the ulcer. Other medications may be prescribed to manage bleeding if it occurs.
Choice D reason:
Antibiotics do not relax stomach muscles or alleviate abdominal pain. Pain relief is typically achieved through acid-reducing medications and other pain management strategies.
