Quiz - Skills & Environment - Aquatic Life Injury

[Pedro Burrito]

From the Skills and Environment section of the PADI Dive Theory Exam:

Which of the following may indicate an injury caused by aquatic life?

a. local swelling and inflammation

b. cherry red lips and fingernail beds

c. a false sense of well being or euphoria

d. both a and c are correct

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.

b- yes, carbon monoxide.

I'm wondering if anyone will search out an organism that may also cause b or c.....

Now we can start a discussion !!!
I think c is not narcosis

Well, it could also be oxygen toxicity--I believe in "VENTID" (list of signs of oxtox), the e stands for euphoria. But I'm sure it is narcosis.

Also agree with Tom. A false sense of well being or euphoria are classic symptoms of narcosis.

The E in VENTID is for ear ringing

Right, sorry. Had to go through it in my head-- it's:
I -- Irritability, anxiety and EUPHORIA. Correct?

Small doses of tetrodotoxin (the toxin from the blue ring octopus and in pufferfish) can cause euphoric symptoms. This is why pufferfish is prepared sometimes with a small amount of the toxin left in.
