The nurse receives the following order: "Ferrous sulfate 325 mg four times a day PO. Give on empty stomach." Even before researching, the nurse guesses that this is because the medication:

is better absorbed when there is no food in the stomach.

is destroyed by acid in the stomach

can cause constipation

is irritating to the gastric mucosa and may cause bleeding

Answer and Explanation

The Correct Answer is B

Choice A rationale: Iron absorption is influenced by several factors, including the presence of food in the stomach. Food can interfere with iron absorption by forming

insoluble complexes with iron, reducing its bioavailability. Therefore, ferrous sulfate should be taken on an empty stomach, preferably one hour before or two hours after meals, to enhance its absorption and effectiveness.

Choice B rationale: Ferrous sulfate is not destroyed by acid in the stomach but instead acid enhances iron absorption by keeping it in a soluble form.

Choice C rationale: Constipation is a common side effect of iron supplementation, but this is not the primary reason for taking it on an empty stomach.

Choice D rationale: Ferrous sulfate can cause gastrointestinal bleeding in some cases, but this is not the primary reason for taking it on an empty stomach.
