A nurse is assisting with teaching a class about medication interactions. The nurse should include that iron preparations should be administered with which of the following?
Orange juice
Cheese
Milk
Antacids containing magnesium
The Correct Answer is A
A. Orange juice. Orange juice is high in vitamin C, which enhances the absorption of iron in the gastrointestinal tract.
B. Cheese: Dairy products, including cheese, can inhibit iron absorption due to the calcium content.
C. Milk: Similar to cheese, milk contains calcium, which can interfere with the absorption of iron.
D. Antacids containing magnesium: Antacids can decrease the absorption of iron, so they should not be taken together.

Correct Answer is C
Explanation
A. Notify the provider immediately if urine turns red-brown in color. Phenytoin can cause urine discoloration, but this is not typically a cause for immediate concern.
B. Obtain an annual flu vaccine while taking phenytoin. While vaccinations are important, there is no specific requirement for flu vaccination solely based on phenytoin use.
C. Shake the suspension vigorously prior to pouring the medication. Phenytoin suspension should be shaken gently to ensure even distribution of the medication.
D. Take an antacid with the medication to avoid gastric upset. Antacids should not be taken simultaneously with phenytoin, as they can decrease its absorption.
Correct Answer is C
Explanation
A. "Stomach acid will inactivate some of the medication if I crush the medication." The purpose of the enteric coating is to protect the stomach lining from irritation, not to prevent inactivation by stomach acid.
B. "If I crush it you might experience a stomach ache or indigestion." While it’s true that crushing may cause stomach discomfort, the primary concern is that it would bypass the enteric coating.
C. "That would release all the medication at once, rather than over time." Crushing enteric-coated aspirin would cause the medication to be released all at once, potentially leading to side effects and reducing its intended effectiveness.
D. "I will crush it and mix it in some ice cream for you." Crushing enteric-coated medications is contraindicated, and it could cause harm.
