IV IV Equipment & Infusion Technology 2

Question 1

An elastomeric infusion device (balloon pump) is used primarily for which type of IV therapy?

Accepted Answer

Ambulatory antibiotic infusions where a portable, non-electronic delivery device is preferred

Answer

Elastomeric pumps use balloon pressure to deliver medication at a preset rate, making them ideal for home or ambulatory antibiotic infusions that do not require rate adjustment.

Question 2

What is the recommended position of the drip chamber when setting up a primary IV infusion set?

Accepted Answer

Half-full to allow accurate drop counting and prevent air from entering the pump tubing

Answer

The drip chamber should be half-full to allow accurate visualization of the drop rate and to prevent air from being drawn into the tubing below the chamber.

Question 3

Which gauge peripheral IV catheter is preferred for rapid fluid resuscitation in an adult trauma patient?

Accepted Answer

16-gauge or larger catheter in the antecubital fossa

Answer

Large-bore (16-gauge or larger) peripheral catheters in large antecubital veins allow the maximum flow rates needed for rapid volume resuscitation in trauma.

Question 4

What does 'KVO' (Keep Vein Open) refer to in IV therapy, and what is a typical KVO rate?

Accepted Answer

A very slow infusion rate (typically 10–30 mL/hour) used to maintain catheter patency between medication administrations

Answer

KVO (Keep Vein Open) is a very slow infusion rate, typically 10–30 mL/hour, used to maintain catheter patency and IV access between scheduled medication administrations.

Question 5

Which of the following correctly describes the 'SASH' flush protocol for peripheral IV catheters?

Accepted Answer

Saline, Administer drug, Saline, Heparin (for heparin-lock catheters)

Answer

The SASH protocol (Saline-Administer-Saline-Heparin) is used for heparin-lock catheters to confirm patency, administer medication, clear residual drug, and maintain patency with heparin.
