A nurse is providing dietary instructions to a client with peptic ulcer disease. Which of the following dietary modifications should the nurse recommend to promote ulcer healing?

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.

Choice A reason:

Nausea and vomiting after meals are common symptoms in acute cholecystitis, but they do not indicate a severe complication. They are typical manifestations of gallbladder inflammation.

Choice B reason:

Mild right upper quadrant pain may be present in acute cholecystitis, but it does not suggest a severe complication.

Choice C reason:

Referred pain to the left shoulder (Kehr's sign) is a classic symptom of splenic rupture or other conditions involving the spleen, not directly related to cholecystitis.

Choice D reason:

This statement is correct. High fever and chills may indicate the presence of infection and sepsis, which can be severe complications of acute cholecystitis.
