From the Diving Physiology Section of the PADI Diving Knowledge Workbook Version 2.02 © PADI 2009:

I will post a daily question from my exams to help newer divers and to encourage more experienced divers to interact gracefully and helpfully with the newer divers.

Reminder - this is a post in the Basic Forum and it is a green zone. Please be nice and on topic.

Thank you for your patience while we try to give people something to discuss other than Covid-19 and/or Politics. I will post the answer covered by the spoiler tag later today.

Think I got it wrong this time. I'm assuming there is no use of a chamber in the scenario.

a. symptoms tending to improve as a result of first aid / usually no change or worsening of condition

In cases of embolism, a victim will often appear to improve once they are treated for shock and begin breathing pure oxygen. In cases of DCS, the condition requires time to develop and, therefore, requires time - and aggressive treatment - to improve. Immediate first aid measures will tend to have little consequence on bubble growth. Symptoms will often not show improvement as a result of first aid.

I have to take a break for a few weeks for personal reasons. I'll resume these questions as soon as I can. Thank you so much for participating!

Yes, this has been great, even though for me personally the pandemic hasn't changed a whole lot.
And thanks for this last question--I was actually in the 10% so far who got it right! Coulda sworn I mixed it up.
