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 B
Explanation
A. 2.0 mg: This notation indicates two milligrams, which is not equivalent to two tenths of a milligram.
B. 0.2 mg: This is the proper way to write two tenths of a milligram.
C. .2 mg: While it may be understood, it is not the preferred notation because it lacks a leading zero, which can lead to misinterpretation.
D. 0.20 mg: This is technically correct but not necessary. It suggests more precision than needed for two tenths and can be misinterpreted as a larger dose.
Correct Answer is B
Explanation
A. Withhold the digoxin dose for elevated BP: Elevated BP is not a contraindication for digoxin administration; rather, the heart rate is the critical factor.
B. Withhold the digoxin dose for decreased heart rate. A heart rate below 60 beats per minute is a contraindication for administering digoxin, as it can increase the risk of toxicity and bradycardia.
C. Administer digoxin 0.25 mg. Given the heart rate of 54/min, the nurse should not administer the full dose.
D. Administer digoxin 0.125 mg. While 0.125 mg may be appropriate in some cases, the heart rate should first be assessed to determine if the medication should be administered at all.
