A client with peptic ulcer disease is scheduled for an upper gastrointestinal endoscopy. The client asks the nurse about the purpose of the procedure. Which of the following responses should the nurse provide?

"The endoscopy will examine your esophagus and stomach for any abnormalities."

"This procedure will assess the blood flow to your intestines and colon."

"The endoscopy will evaluate your kidney function and urinary system."

"This procedure will help diagnose conditions in your lower digestive tract."

Answer and Explanation

The Correct Answer is A

Choice A reason:

This statement is correct. An upper gastrointestinal endoscopy is a diagnostic procedure that uses a flexible tube with a camera (endoscope) to visualize the esophagus, stomach, and duodenum. It helps identify abnormalities, such as peptic ulcers, inflammation, or tumors.

Choice B reason:

Assessing blood flow to the intestines and colon is not the purpose of an upper gastrointestinal endoscopy. This procedure focuses on the upper digestive tract.

Choice C reason:

Evaluating kidney function and the urinary system is unrelated to an upper gastrointestinal endoscopy, which focuses on the upper digestive tract.

Choice D reason:

Diagnosing conditions in the lower digestive tract is not the purpose of an upper gastrointestinal endoscopy. Lower digestive tract evaluations are typically done using colonoscopy or sigmoidoscopy.

Correct Answer is C

Explanation

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.

A. "The CT scan uses a magnetic field, so there is no radiation exposure." B. "The amount of radiation used in a CT scan is very low and safe." C. "There is no need to worry about radiation as the scan is done quickly." D. "CT scans do not use radiation; they use sound waves for imaging."

Correct Answer is B

Explanation

Choice A reason:

CT scans use X-rays, not magnetic fields, to create detailed cross-sectional images of the body. They involve radiation exposure.

Choice B reason:

This statement is correct. While CT scans use X-rays, the amount of radiation used in modern CT machines is relatively low and considered safe. The benefits of the diagnostic information obtained from the scan usually outweigh the risks associated with the small amount of radiation exposure.

Choice C reason:

The speed of the scan does not impact the radiation exposure. The amount of radiation used in a CT scan remains the same regardless of the scan duration.

Choice D reason:

CT scans use X-rays, not sound waves. Sound waves are used in ultrasound imaging, not in CT scans.
