Correct Answer is D

Explanation

Choice A rationale: Carbon dioxide level is not a direct indicator of the blood's ability to transport oxygen.

Choice B rationale: Surfactant level is not a direct indicator of the blood's ability to transport oxygen; surfactant is related to lung function.

Choice C rationale: Bicarbonate ion level is more related to acid-base balance and not a direct indicator of the blood's ability to transport oxygen.

Choice D rationale: Hemoglobin level provides the most information about the blood's ability to transport oxygen, as hemoglobin carries oxygen to tissues.

A. is supplied in an ampule. B. is to be mixed with another medication. C. has to be reconstituted. D. is clear.

Correct Answer is A

Explanation

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.
