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.

Correct Answer is B

Explanation

Choice A rationale: Administering the medication against the client's will is not respectful of the client's autonomy and right to make decisions about her own care.

Choice B rationale: Withholding the medication and reporting it to the prescriber is appropriate. The prescriber can reassess the situation and determine the next course of action.

Choice C rationale: Withholding the medication and filing an incident report may be premature; it is essential to involve the prescriber first.

Choice D rationale: Informing the client that the medication must be taken until the nurse gets an order to discontinue it may not be the best approach, as it does not respect the client's right to refuse treatment. The prescriber should be involved in the decision-making process.

A. magnesium of 1.8 mEq/L B. potassium 3.6 mEq/L C. calcium of 8.7 mg/dL D. phosphorus of 1.2 mg/dl.

Correct Answer is A

Explanation

Choice A rationale: A serum magnesium level of 1.8 mEq/L is lower than the normal range and can be associated with alcohol withdrawal.

Choice B rationale: Potassium level within the normal range is not specifically indicative of alcohol withdrawal.

Choice C rationale: Calcium level within the normal range is not specifically indicative of alcohol withdrawal.

Choice D rationale: Phosphorus level within the normal range is not specifically indicative of alcohol withdrawal.
