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 ["2"]
Explanation
Step 1 is: The doctor has ordered 650 mg of aspirin and each tablet contains 325 mg. So, to find out how many tablets to administer, we divide the ordered dose by the dose per tablet.
Step 2 is: 650 mg ÷ 325 mg/tablet = 2 tablets.
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.
