Tests Replaced – Please Read

May 8, 2026 – Airway Module A, B, C, D Post-Tests and Pre-Tests B and C

1. Tests A, B, C, and D were updated to reflect, when blood gases are displayed, the use of the word: Base excess followed by a positive or negative number. This display matches how blood gases are reported. There is also an Asterix before the word “Base” with this information at the bottom of the page whenever there is a blood gas question:  Base is reported as base excess (BE); negative values = base deficit. The footer of the page has the change date so you know you are using the most current test. No answers were affected so the key was not replaced.

2. Pretests B and C were also updated because there were blood gases on those tests.
