A client is admitted to the hospital with a diagnosis of R/O appendicitis. Which abbreviation would describe the location of a client's appendix?

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.

Choice A rationale: Poor tissue perfusion from circulatory insufficiency can affect oxygenation, but fluid in the lungs primarily impacts gas exchange at the alveolar level.

Choice B rationale: Decreased diffusion of oxygen from the alveoli to the blood is a major factor affecting oxygenation when fluid is present in the lungs.

Choice C rationale: Lowered oxygen carrying capacity can affect oxygenation but is not the primary concern in the presence of fluid in the lungs.

Choice D rationale: Decreased concentration of oxygen in the air is not the primary factor affecting oxygenation in a client with fluid in the lungs.
