Before you begin...

This quiz consists of case-based, multiple-choice questions of beginner difficulty. The clinical information provided will often be minimal and you will rarely have access to any special blood tests or diagnostic imaging.

Instead, you will need to make management decisions using the information provided by venous or arterial blood gases.

The quiz should take no more than 40 minutes to complete in total.

When you finish and hit 'submit,' your score will be e-mailed to you. Your e-mail address will not be used for any other purpose.

Good luck! When you are ready, hit 'Next' below.
