For intravenous therapy to be considered "central line therapy", the tip of the catheter must be placed in the superior vena cava.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Intravenous therapy is considered "central line therapy" when the tip of the catheter is placed in the superior vena cava. The superior vena cava is a large vein that carries deoxygenated blood from the upper body to the heart. Placing the catheter in this location allows for efficient and effective delivery of medications and fluids directly into the bloodstream. It also reduces the risk of complications associated with peripheral intravenous therapy. Therefore, the statement is true.

List the following veins in order from fastest flow to slowest flow: Subclavian, cephalic/basilic, superior vena cava

Correct Answer
superior vena cava, subclavian, cephalic/basilic

Explanation
The superior vena cava is a large vein that carries deoxygenated blood from the upper body back to the heart. It has the fastest flow because it receives blood from multiple veins, including the subclavian veins. The subclavian veins are located under the collarbone and carry blood from the upper limbs. They have a slightly slower flow compared to the superior vena cava. The cephalic and basilic veins are located in the arm and forearm and have the slowest flow among the listed veins. Therefore, the correct order from fastest flow to slowest flow is superior vena cava, subclavian, cephalic/basilic.

List 3 reasons why a patient would require a central line versus a peripheral line.

Correct Answer
osmolarity of solution, length of therapy, poor venous access, frequent lab draws, irritating solution

Explanation
A patient may require a central line instead of a peripheral line for several reasons. First, the osmolarity of the solution being administered may be too high to be safely infused through a peripheral line. Second, if the patient needs a long-term therapy, a central line provides a more stable and reliable access point. Third, if the patient has poor venous access, a central line can be inserted into a larger vein to ensure successful administration of medications or fluids. Additionally, if frequent lab draws are necessary, a central line allows for easier blood sampling. Lastly, if the solution being infused is irritating to the peripheral veins, a central line can be used to minimize discomfort and potential damage.

A new theory regarding ctherter related infections involves the development of biofilm during insertion.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The statement suggests that a new theory has emerged linking catheter-related infections to the formation of biofilm during insertion. Biofilm is a slimy layer that bacteria can form on surfaces, including catheters. This biofilm can provide a protective environment for bacteria, making it difficult for antibiotics to penetrate and eliminate them. Therefore, it is reasonable to conclude that the statement is true, as the development of biofilm during catheter insertion can contribute to infections.

The preferred dressing for PICC lines is:
- A.
  
  Gauze
- B.
  
  Kerlix
- C.
  
  Transparent
- D.
  
  Hydrocolloid
Correct Answer
C. Transparent

Explanation
Transparent dressings are the preferred choice for PICC lines because they allow for easy visualization of the insertion site, making it easier to monitor for any signs of infection or complications. They also provide a barrier against external contaminants while still allowing for breathability and moisture control. Additionally, transparent dressings are flexible and conformable, providing a comfortable and secure fit around the PICC line.

What is the name of the correct flushing method used on central lines?

Correct Answer
push/pause or start/stop

Explanation
The correct flushing method used on central lines is either push/pause or start/stop. This method involves pushing a small amount of fluid into the line, pausing for a few seconds, and then repeating the process. This helps to ensure that the line is properly flushed and prevents any blockages or clot formation. It is important to follow this flushing method to maintain the patency and function of central lines.

List 2 indications when it is necessary to flush a PICC.

Correct Answer
before use, after use, weekly or per policy,

Explanation
The PICC (Peripherally Inserted Central Catheter) is a long-term intravenous access device that is inserted into a vein in the arm and threaded through to a larger vein near the heart. Flushing the PICC is necessary to ensure that it remains patent and free from any blockages. Flushing before use ensures that the catheter is clear and ready for medication administration. Flushing after use helps to prevent blood clot formation and maintain catheter patency. Flushing weekly or per policy is important to prevent the build-up of residue or bacteria inside the catheter, reducing the risk of infection.

Wipe the injection port of the PICC for a minimum of how many seconds before accessing?
- A.
  
  45
- B.
  
  25
- C.
  
  15
- D.
  
  60
Correct Answer
C. 15

Explanation
Before accessing the injection port of the PICC, it is recommended to wipe it for a minimum of 15 seconds. This is important to ensure proper disinfection and minimize the risk of contamination. Wiping the injection port for a sufficient amount of time allows the disinfectant to effectively kill any potential microorganisms on the surface, reducing the risk of infection during the procedure.

You are preparing to flush the PICC access port with both saline and dilutional heparin. You only need prep the access port with saline once.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
The statement is false because when preparing to flush the PICC access port with both saline and dilutional heparin, you need to prep the access port with saline multiple times. Flushing the access port with saline helps to clear any blockages or debris before administering the heparin solution. Therefore, the access port needs to be prepped with saline more than once to ensure proper cleaning and preparation.
