Correct Answer is C

Explanation

Choice A reason:

Indigestion and discomfort are potential issues, but the primary reason for a low-fat diet after cholecystectomy is related to gallstone prevention and liver function.

Choice B reason:

There is no direct link between fatty foods and medication absorption in the context of post-cholecystectomy care.

Choice C reason:

This statement is correct. Following a low-fat diet after cholecystectomy helps prevent the formation of new gallstones and reduces stress on the liver, as the gallbladder's role in storing and releasing bile for

fat digestion is compromised.

Choice D reason:

While fatty foods can lead to digestive problems for some individuals, the primary concern in a client post-cholecystectomy is gallstone prevention and liver support.

A. "The ultrasound will help assess the blood flow to your liver." B. "The test will provide detailed images of your gallbladder and check for gallstones." C. "The ultrasound will measure the acidity levels in your stomach." D. "The test is done to evaluate your kidney function."

Correct Answer is B

Explanation

Choice A reason:

Assessing blood flow to the liver is not the primary purpose of an abdominal ultrasound in a client with suspected cholelithiasis.

Choice B reason:

This statement is correct. An abdominal ultrasound is a non-invasive imaging test that provides detailed images of the gallbladder and surrounding structures, helping to visualize the presence of gallstones and assess the gallbladder's condition.

Choice C reason:

Measuring acidity levels in the stomach is not related to the diagnostic evaluation of cholelithiasis.

Choice D reason:

Evaluating kidney function is not the primary purpose of an abdominal ultrasound for a client with suspected cholelithiasis.
