The Hero’s Blood Quiz

Hello Great Hero!

Here is the blood quiz so you can take it before class. We will be celebrating our Blood Drive success on Monday by watching a video on Pt. Assessment in the battlefield and then relaxing with our colleagues afterwards.

If 85% of the class completes this and turn it in before class, we will get to enjoy the movie – so call your friends.

Please take a moment to think about our success last Friday. We collected over 50 donations of blood. Each donation saves the lives of three people. Over 150 families will not be mourning the loss of a loved one because of your efforts. I find it strange that you can save 150 lives and it doesn’t make the news. Well, we do what we do as ambassadors of health because we are empowered to do so, and it is the right thing to do. Just imagine how many lives Frank has saved in his 32 years as a paramedic.  Think of the relief ER doctors, nurses and other health care professionals bring everyday – every year.

Friday, you joined the ranks of health heroes.  May your successes be many. Congratulations.
