The nurse recognizes that the patient who might have the most difficult time coping with a stressor is the one who:

A. These are indicative of inflammation within the vein, which is characteristic of phlebitis. Warmth is a common sign of inflammation, and the palpable cord suggests that the vein may be hardened or cord- like due to inflammation and irritation.
B. While this could indicate some form of vascular injury or extravasation, it is not a typical presentation of phlebitis. Phlebitis involves inflammation of the vein, which may cause redness, warmth, and tenderness along the course of the vein, but it typically does not manifest as a raised ecchymotic (bruised) area.
C. Swelling occurs due to inflammation within the vein, and tenderness is often present as a result of the irritation and inflammation. These symptoms are commonly observed in cases of phlebitis but are not specific.
D. These are not typical signs of phlebitis. Blanching (turning white) and coolness of the skin may suggest reduced blood flow to the area, which could occur in cases of ischemia or thrombosis but are not characteristic of phlebitis.

D. fluids and medications that may be irritating to peripheral veins can be given through a central venous access device (CVAD). CVADs are beneficial because they allow for the administration of vesicants, irritant solutions, or large volumes of fluid that could damage smaller, peripheral veins. They also provide reliable venous access for patients who are critically ill, have poor venous access, or require long-term medication treatment, such as for pain, infection, cancer, or to supply nutrition.
A. While central lines do have a risk of sepsis, it is not necessarily lower than peripheral sites
B. Patency confirmation methods are not exclusive to CVADs and are also applicable to peripheral IV catheters.
C. Both placement and maintenance require strict aseptic techniques to minimize the risk of infection.
