The nurse is providing care for an elderly client who has cognitive changes. The nurse recognizes that which statement regarding dementia and delirium is true?
Both are accompanied by changes in level of consciousness.
Memory is affected equally in both diseases.
Only delirium is reversible.
The progression of both diseases is slow.
The Correct Answer is C
C. Delirium is often reversible once the underlying cause is identified and treated (e.g., correcting electrolyte imbalances, managing infections, discontinuing medications contributing to delirium). With appropriate intervention, the mental status can improve, and the individual can return to their baseline cognitive function.
A. Dementia, on the other hand, is a chronic, progressive syndrome that primarily affects memory, thinking, behavior, and the ability to perform everyday activities. It does not typically cause acute changes in consciousness.
B. Memory impairment is a hallmark feature of dementia, especially in the early stages. In contrast, delirium primarily affects attention, awareness, and cognition acutely, with memory impairment being variable and not a defining feature.
D. Delirium develops rapidly, often over hours to days, in response to an acute medical condition, medication change, or other factors. It is characterized by a fluctuating course and can resolve once the underlying cause is managed.

Correct Answer is ["A","B","D"]
Explanation
A. This is the part of the IV administration set that pierces the IV bag or bottle to allow fluid to flow into the tubing. The plastic insertion spike must remain sterile because it comes into direct contact with the fluid within the IV container. Contamination of the spike could introduce microorganisms into the IV solution.
B. The catheter adapter or hub is the part of the IV administration set where the IV catheter or cannula connects. It is crucial for this part to remain sterile to prevent introducing pathogens into the bloodstream during catheter insertion or manipulation.
D. The Y-site injection port is a branching point in the IV tubing where additional medications or fluids can be infused into the IV line. It must remain sterile to prevent contamination when administering medications or secondary infusions.
C. The drip chamber is located in the IV tubing, just below the IV bag or bottle. It is designed to visualize and regulate the flow of IV fluid into the patient. It does not directly contact the bloodstream or the IV fluid inside the tubing.
E. Roller clamp to regulate flow (Option E) does not necessarily need to be sterile because it does not come into direct contact with IV fluid or the patient's bloodstream. However, it should be handled with clean hands to maintain general cleanliness and to prevent contamination of other sterile parts of the IV set.
Correct Answer is B
Explanation
B. This response acknowledges the urgency of the situation and seeks clarification on the appropriate administration technique. It demonstrates readiness to follow through with the medical resident's directive while ensuring safe and effective administration.
A. This response reflects hesitation and a concern about administering a medication that the nurse did not prepare or is unfamiliar with. In a critical situation like a "code blue," timely administration of medications as directed by the medical team is crucial for patient outcomes.
C. Checking IV patency is important to ensure the medication can be administered properly. However, in a "code blue" situation where time is critical, this step might unnecessarily delay administration of the medication.
D. This response indicates willingness to follow the directive given by the medical resident. It also emphasizes the importance of documenting and obtaining proper orders after the immediate crisis has been addressed.
