Hi everyone,

Thank you for participating to the trivia game. Unfortunately, the majority chose the incorrect answer. The correct answer was not even the second most vote. So, only the milestone reward chapter will be released for your reading pleasure.

Now, let's go over the trivia question.

In an emergency situation at the hospital, an intraosseous access needed to be install to a patient with a weight of 150kg, in hypovolemic shock. Where should it be installed?

There are many ways to find the correct answer, but I'll just tell you about the easiest one. And yes, you don't need to study health science to get that one right.

A short explanation of what an intraosseous access is. Usually, intraveinous catheter is the most widely used access during emergency situation or during stay in hospital for IV medication because you want those medication to go in your bloodstream quickly, bypassing the long process of gastrointestinal absorption.

At times, during emergency, it's extremely difficult to open an intraveinous access due to various reasons like obesity, chronic sickness, IV drug users, etc. But it doesn't change the fact that you need to shoot medication in bloodstream asap or patient might died. Thus, the whole meaning of opening an intraosseous access. It takes less than a minute to install one because you just need to drill an opening to reach the medullary cavity of the bone where blood vessels are. Yes, bones have blood vessels in it, but not all types of bones have that. Long bones have the largest blood vessels system amongst all types of bone (that's why you can massively bleed from a tibia fracture).

Now, how to find the answer.

  • Google my friend
    • There are many hints in the question.
    • I want to know where the intraosseous catheter should be install, so you just need to google "intraosseous placement site" or any similar terms.
    • You will find that the ribs is not a place where you install intraosseous access. Since ribs is rule out, so was option "All of these answers."
    • Which leave you with two options to choose from: humerus and sternum.
    • Sternum is too thin of a bone and is only used in special case since it required special equipment. So, sternum also rule out. Besides in the question, the patient is in hypovolemic shock which means there's a possibility that if things went south, we might need to do CPR and doing heart compression on a sternum with an intraosseus catheter is a big no-no.
 

That's it for the explanations. On with the chapters.
