The nurse is assessing internal variables that influence a client's health care beliefs and practices. As part of this assessment, the nurse should consider the client's:

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.

B. Activating a code blue or the facility's emergency response system will bring immediate assistance and resources to the client's bedside. This is crucial to initiate prompt resuscitative measures if indicated and to involve additional healthcare providers in the management of the emergency.

A. While it might be appropriate in some situations to provide privacy or support to the partner, in this urgent scenario where the client is unresponsive and not breathing, the priority should be immediate assessment and intervention for the client's condition.

C. While notifying the physician is important, especially to inform them of the client's condition and potentially discuss the DNR status, it is not the most immediate action in this urgent situation where the client is unresponsive and not breathing. Direct intervention and assessment are needed first.

D. Asking the partner to make a DNR decision immediately is not appropriate as the first action in this scenario. It is crucial to focus first on the client's immediate needs for assessment and potentially resuscitative measures if indicated. The discussion about the DNR order should occur in a timely manner but is secondary to addressing the client's current medical emergency.
