Intraosseous (IO) access delivers medications and fluids to which anatomical structure?
Answer: The medullary cavity of the bone, which connects to the venous circulation
IO needles enter the medullary cavity, which contains a non-collapsible venous network that rapidly delivers fluids and drugs into central circulation.
The proximal tibia is a common IO site. It is located approximately:
Answer: 2 cm distal to the tibial tuberosity on the anteromedial flat surface
The proximal tibial IO site is approximately 2 cm distal to the tibial tuberosity on the flat anteromedial surface of the tibia.
Before infusing fluid through an IO needle, you should:
Answer: Inject lidocaine slowly if the patient is conscious to reduce pain
In conscious patients, IO infusion is painful; 2% preservative-free lidocaine injected slowly before fluids significantly reduces discomfort.
Which of the following is an absolute contraindication to IO placement at a specific site?
Answer: A fracture in the bone at the intended site
A fracture at the intended IO site is an absolute contraindication because fluid would extravasate into surrounding tissue through the fracture.
You are administering a 20 mL/kg fluid bolus to a 70 kg adult in hemorrhagic shock. How many mL should you infuse?
Answer: 1,400 mL
20 mL/kg × 70 kg = 1,400 mL; this is the standard initial fluid bolus for hypovolemic/hemorrhagic shock resuscitation.
A patient in anaphylaxis has an IV established. Which of the following is the FIRST-LINE medication to administer IV?
Answer: Epinephrine 1:1,000 IM (or diluted IV per protocol)
Epinephrine is the first-line treatment for anaphylaxis; while IM is standard, diluted IV epinephrine (1:10,000) may be used per protocol in severe cases.
