The nurse knows that an advantage of using a central venous access device is that:
central lines have a lower risk of sepsis than peripheral sites.
patency can be confirmed with a normal saline flush unlike peripheral IV catheters.
placement can be performed with medical aseptic technique.
fluids & medications that may be irritating to peripheral veins can be given.
The Correct Answer is D
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.

Correct Answer is A
Explanation
A. Changing the client's arm position, such as raising or lowering it, could potentially improve flow by altering the gravitational pull on the IV solution. For example, raising the arm could increase flow due to increased pressure, while lowering it could decrease flow. However, this approach may not always be effective and should be done cautiously to avoid discomfort or compromising the integrity of the IV site.
B. Using an infusion pump can help regulate the flow rate of the IV solution more accurately compared to gravity alone. However, if the IV is running slowly due to factors unrelated to the infusion rate setting, such as a partial blockage or resistance in the IV line, using an infusion pump may not necessarily improve the flow rate.
C. Lowering the height of the IV pole can increase the gravitational force acting on the IV solution, potentially improving flow. This adjustment can help overcome minor obstructions in the IV line and facilitate better flow. However, it should be done cautiously to avoid excessive pressure on the IV site or causing discomfort to the client.
D. Opening the clamp fully for an extended period is not a recommended approach. It could lead to rapid infusion or an excessive flow rate, increasing the risk of complications such as fluid overload or vein irritation. Additionally, this action does not address the underlying reason for the slow flow rate and may not effectively resolve the issue.
Correct Answer is B
Explanation
B. A PICC line is a long, flexible catheter inserted into a peripheral vein, typically in the upper arm, and advanced until the tip lies in the superior vena cava or the cavoatrial junction. PICC lines are suitable for long-term venous access and are often used for administering medications, including antibiotics, over several weeks or months. They offer stable and reliable access, reducing the need for frequent venipunctures.
A. Butterfly needles are typically used for short-term venous access, such as for blood draws or administering medications that do not require long-term therapy. They are not suitable for prolonged use or for administering medications over several weeks, as they are not designed for secure and stable access over an extended period.
C. A peripheral IV-lock, also known as a saline lock or heplock, is a short catheter inserted into a peripheral vein and then capped off for intermittent use. While peripheral IV-locks are suitable for short-term venous access, they are not ideal for prolonged therapy lasting several weeks. Additionally, they may not provide the necessary stability and reliability for administering IV antibiotics over an extended period.
D. A small gauge peripheral angiocath refers to a short catheter inserted into a peripheral vein for intravenous access. While a larger gauge catheter, such as a 16-gauge, may allow for faster infusion rates and is suitable for certain situations requiring rapid fluid administration, it may not be the most appropriate choice for long-term IV antibiotic therapy. The choice of gauge depends on factors such as the client's vein size, the viscosity of the medication, and the duration of therapy.
