Question 1

Blood can be routinely collected from a midline peripheral catheter.

Accepted Answer

Midline peripheral catheters are designed for therapies lasting less than 4 weeks and are not typically used for routine blood collection due to the risk of damaging the catheter or causing patient discomfort. Blood draws are generally performed through venipuncture or central venous catheters designed for such purposes.

Question 2

Implanted ports are used only for administration of chemotherapy and cannot be used for blood collection.

Accepted Answer

Implanted ports can also be used for blood collection, as they provide direct access to the bloodstream. This can reduce the need for repeated needle sticks and minimize discomfort for patients who require frequent blood tests. However, it is important to ensure that the port is used for blood collection only when it is specifically designed and approved for this purpose, as some types of ports may be more suitable for chemotherapy administration than for blood draws.

Question 3

Blood for laboratory testing is only drawn from peripheral access devices at the time of insertion.

Accepted Answer

The answer of Blood for laboratory testing is only drawn...

Question 4

Heparin is the preferred solution for flushing catheters.

Accepted Answer

Normal saline is typically the preferred solution for flushing catheters, as it is effective and reduces the risk of complications associated with heparin, such as heparin-induced thrombocytopenia.

Question 5

Blood cannot be drawn from a peripheral inserted central catheters (PICC) line that is infusing total parental nutrition (TPN).

Accepted Answer

When TPN is being infused through a PICC line, it is important not to draw blood from the same line as it can alter the accuracy of TPN infusion and cause complications.

Question 6

Flushing peripheral IVs and central venous catheters (CVCs) is performed to maintain patency of the catheter.

Accepted Answer

Flushing peripheral IVs and CVCs helps prevent blockages and maintain catheter patency.

Question 7

A noncoring needle is used to access an implanted port.

Accepted Answer

A noncoring needle is specifically designed to puncture the septum of an implanted port without coring or removing a piece of the rubber or silicone material from the septum. This helps minimize damage to the port and prevent particles from dislodging and entering the bloodstream.
