It is most critical for the nurse to use a filtered needle when preparing a parenteral medication that:

is supplied in an ampule.

is to be mixed with another medication.

has to be reconstituted.

is clear.

Answer and Explanation

The Correct Answer is A

Choice A rationale: An ampule is a glass container that contains a single dose of medication. The medication is sealed under vacuum and must be broken open before use hence a filtered needle is a needle that has a filter in the hub that prevents glass particles from entering the syringe when drawing up the medication from the ampule. Glass particles can cause tissue damage, inflammation, infection, or embolism if injected into the patient. Therefore, it is most critical for the nurse to use a filtered needle when preparing a medication from an ampule.

Choice B rationale: Using a filtered needle is not specifically related to medications that need to be mixed with another medication.

Choice C rationale: Using a filtered needle is not necessary when preparing a parenteral medication that has to be reconstituted to remove particulate matter or contaminants.

Choice D rationale: Using a filtered needle is not specifically related to clear medications; it is more focused on the need to filter solutions.

Correct Answer is B

Explanation

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.

A. Acetaminophen 500 mg PO q4h PRN headache B. Dulcolax suppository one per rectum PRN C. Aspirin 10 mg PO crush and put in apple sauce D. Fentanyl 25 mcg/h via transdermal patch daily E. Morphine 0:4 mg IV q4h PRN severe pain

Correct Answer is ["B","D","E"]

Explanation

Choice A rationale: Acetaminophen 500 mg PO is subject to the first pass effect as it is absorbed through the gastrointestinal system.

Choice B rationale: Dulcolax suppository is not subject to the first pass effect as it is administered rectally.

Choice C rationale: Aspirin 10 mg PO is subject to the first pass effect as it is absorbed through the gastrointestinal system.

Choice D rationale: Fentanyl 25 mcg/h via transdermal patch avoids the first pass effect as it is absorbed through the skin.

Choice E rationale: Morphine 0.4 mg IV avoids the first pass effect as it is administered intravenously.
