AEMT IV Therapy and Fluid Administration

Question 1

Which IV fluid is classified as an isotonic crystalloid and is most commonly used for volume resuscitation in the prehospital setting?

Accepted Answer

0.9% Normal Saline (NS)

Answer

0.9% Normal Saline is an isotonic crystalloid that remains in the intravascular space and is the most widely used prehospital resuscitation fluid.

Question 2

The preferred IV site for most adult emergency patients is:

Accepted Answer

Antecubital fossa vein

Answer

The antecubital fossa provides large, easily accessible veins and allows rapid fluid delivery, making it the preferred site in emergencies.

Question 3

A 20-gauge IV catheter is inserted and the patient is to receive a fluid bolus. What does increasing the IV bag height accomplish?

Accepted Answer

It increases flow rate by increasing hydrostatic pressure

Answer

Raising the IV bag increases hydrostatic pressure in the tubing, which increases the flow rate of the infusing fluid.

Question 4

You attempt IV access twice without success. Per most AEMT protocols, you should next:

Accepted Answer

Consider IO access or notify medical direction

Answer

Most protocols limit peripheral IV attempts to two before escalating to IO access or contacting medical direction for guidance.

Question 5

Which of the following is a sign of IV infiltration?

Accepted Answer

Swelling, coolness, and pain at the insertion site

Answer

Infiltration occurs when fluid leaks into surrounding tissue, causing local swelling, coolness, and pain at the insertion site.
