A client will require IV antibiotics for several weeks. Which venous access device would be most appropriate to be used for this client?

a butterfly needle

a peripherally inserted central catheter

a peripheral IV-lock

a small gauge (16g) peripheral anglocath

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is D

Explanation

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.

A. higher than the piggyback medication. B. lower than the piggyback medication. C. at the same height as the the piggyback bag. D. lower than the IV insertion site.

Correct Answer is A

Explanation

A. Positioning the primary IV solution bag higher than the piggyback medication bag creates a pressure gradient, allowing the primary solution to infuse first. Once the primary solution has finished, the secondary piggyback medication automatically starts infusing. This setup ensures that the primary solution is fully infused before the piggyback medication begins.
B. Placing the primary IV solution bag lower than the piggyback medication bag is not the standard practice. This setup would create a pressure gradient that could result in the piggyback medication infusing before the primary solution, which is not desirable. It could lead to incomplete infusion of the primary solution and compromise the effectiveness of the treatment.
C. Positioning the primary IV solution bag at the same height as the piggyback bag does not create a pressure gradient for sequential infusion. As a result, both solutions would flow at the same rate, and it would be challenging to control the order of infusion. This setup is not appropriate for administering IV antibiotics via piggyback because it does not ensure the proper sequence of infusion.
D. The height of the IV solution relative to the insertion site is essential for proper infusion and preventing complications such as infiltration or phlebitis. Ideally, the IV solution should be hung at a height that allows for a gentle flow of fluid into the vein without causing excessive pressure or backflow. Placing the IV solution lower than the insertion site helps facilitate gravity-assisted flow into the vein.
