A patient who is scheduled for a barium swallow asks a nurse why a laxative is necessary after the procedure. Which of the following responses should the nurse make?
It helps eliminate the barium.
The medication has been prescribed by your provider.
The medication will turn your stool white.
It is the protocol at this facility.
The Correct Answer is A
Choice A rationale
A laxative is necessary after a barium swallow procedure because barium can cause constipation or impacted stool if it isn’t completely cleared from the body. The laxative helps to ensure that all of the barium leaves the body.
Choice B rationale
While it’s true that the medication has been prescribed by the provider, this doesn’t explain why it’s necessary after a barium swallow procedure.
Choice C rationale
The medication will not turn the stool white. However, the barium used in the procedure can cause the stool to be lighter in color until it’s completely passed from the body.
Choice D rationale
The use of a laxative after a barium swallow is not just a protocol at the facility, but a medical necessity to prevent constipation or impacted stool caused by the barium

Correct Answer is A
Explanation
Choice A rationale
Acute pancreatitis is a condition characterized by inflammation of the pancreas. The most common cause of acute pancreatitis is gallstones, which can become lodged in a bile or pancreatic duct and cause inflammation. Gallstones are hardened deposits of digestive fluid that can form in your gallbladder, and when they block the ducts leading from the gallbladder to the intestines, they can cause sharp pain in the upper abdomen that quickly worsens. This pain can radiate to the back, another common symptom of acute pancreatitis. Therefore, a history of gallstones is a significant factor to anticipate in a client with acute pancreatitis.
Choice B rationale
GERD, or gastroesophageal reflux disease, is a chronic condition where stomach acid flows back up into the esophagus causing heartburn and other symptoms. While GERD can lead to discomfort and complications like esophagitis, it does not typically cause acute pancreatitis.
Choice C rationale
Diabetes mellitus is a chronic condition that affects the body’s ability to use blood sugar for energy. While diabetes can lead to a host of health complications, it is not typically a direct cause of acute pancreatitis.
Choice D rationale
Shock is a life-threatening condition that requires immediate medical attention. It occurs when the body is not getting enough blood flow, leading to insufficient oxygen and nutrients for your cells and organs. Shock can be a result of severe acute pancreatitis, but it is not a cause.
Correct Answer is ["22.5"]
Explanation
The order is for potassium chloride 30 mEq. The available medication is potassium chloride 20 mEq/15mL. To calculate the amount to administer: Step 1 is: Set up a proportion to solve for the unknown quantity (X), which is the volume in mL to administer. The proportion is (20 mEq
/ 15 mL) = (30 mEq / X mL).
Step 2 is: Cross-multiply to solve for X. X = (30 mEq * 15 mL) ÷ 20 mEq.
Step 3 is: Calculate X. X = 22.5 mL. So, the nurse should administer 22.5 mL of potassium chloride.
