Which IV fluid is classified as an isotonic crystalloid and is most commonly used for volume resuscitation in the prehospital setting?
Answer: 0.9% Normal Saline (NS)
0.9% Normal Saline is an isotonic crystalloid that remains in the intravascular space and is the most widely used prehospital resuscitation fluid.
The preferred IV site for most adult emergency patients is:
Answer: Antecubital fossa vein
The antecubital fossa provides large, easily accessible veins and allows rapid fluid delivery, making it the preferred site in emergencies.
A 20-gauge IV catheter is inserted and the patient is to receive a fluid bolus. What does increasing the IV bag height accomplish?
Answer: It increases flow rate by increasing hydrostatic pressure
Raising the IV bag increases hydrostatic pressure in the tubing, which increases the flow rate of the infusing fluid.
You attempt IV access twice without success. Per most AEMT protocols, you should next:
Answer: Consider IO access or notify medical direction
Most protocols limit peripheral IV attempts to two before escalating to IO access or contacting medical direction for guidance.
Which of the following is a sign of IV infiltration?
Answer: Swelling, coolness, and pain at the insertion site
Infiltration occurs when fluid leaks into surrounding tissue, causing local swelling, coolness, and pain at the insertion site.
Lactated Ringer's (LR) solution differs from 0.9% NS in that LR:
Answer: Contains potassium, calcium, and lactate, more closely mimicking plasma electrolytes
Lactated Ringer's contains electrolytes (Na⁺, K⁺, Ca²⁺, Cl⁻, lactate) that more closely approximate plasma composition compared to normal saline.
