A nurse is providing instructions to a patient who is scheduled for a barium swallow to assess dysphagia.
Which of the following patient statements would indicate to the nurse that the instructions have been understood?
I will maintain a clear liquid diet 24 hours before the test.
I will drink plenty of fluids after the test.
I will expect my stool to be black after this procedure.
I will expect a warm feeling when the dye is injected.
The Correct Answer is B
Choice A rationale
While it’s important to prepare for a barium swallow test, maintaining a clear liquid diet 24 hours before the test is not typically required.
Choice B rationale
Drinking plenty of fluids after the test is indeed a correct instruction. The barium used in the test can cause constipation or impacted stool if it does not pass out of the body. Drinking ample fluids helps flush the contrast from the gastrointestinal system.
Choice C rationale
While it’s true that the stool may be discolored after a barium swallow test, it’s more likely to be lighter or white, not black.
Choice D rationale
The barium swallow test does not involve the injection of any dye that would cause a warm feeling. This sensation is more commonly associated with the injection of contrast dye in other types of imaging tests, not a barium swallow.

Correct Answer is B
Explanation
Choice A rationale
Consuming large meals can exacerbate GERD symptoms. Smaller, more frequent meals are recommended to reduce the volume of food in the stomach at any one time, thereby reducing the pressure on the lower esophageal sphincter.
Choice B rationale
Identifying and avoiding foods that cause discomfort is a key strategy in managing GERD. Foods that commonly trigger GERD symptoms include fatty foods, spicy foods, acidic foods, and caffeine.
Choice C rationale
Using pillows to elevate the head and upper body during sleep can help prevent nighttime GERD symptoms. Gravity helps keep stomach acid in the stomach, reducing the chance of it flowing back into the esophagus.
Choice D rationale
Lying down after a meal can exacerbate GERD symptoms. It is recommended to wait at least three hours after eating before lying down.
Correct Answer is C
Explanation
Choice A rationale
Aspartate aminotransferase (AST) is an enzyme that is found in various tissues, including the liver. Elevated levels of AST can indicate liver damage or disease.
Choice B rationale
Albumin is a protein that is made by the liver. It helps keep fluid in the bloodstream so it doesn’t leak into other tissues. Low levels of albumin can indicate liver disease.
Choice C rationale
Lipase is an enzyme that is produced by the pancreas and used in the digestion of fats. It is not a marker of liver function.
Choice D rationale
Alanine transaminase (ALT) is an enzyme found mostly in the cells of the liver and kidney. Much like AST, high levels of ALT can indicate liver damage or disease.
