A 49-year-old man was fishing in a stream of cold water when he became submerged after getting tangled in some hidden roots. The patient was pulled from the stream by friends after approximately 5 minutes of submersion. Your assessment reveals him to be responsive to painful stimuli and breathing 5 times per minute. His pulse is weak and rapid. Which of the following instructions should you give to the team of rescuers?
A) Do not wipe the water off him. It will keep his body cool and protect vital organs like his brain and heart.

C) I need someone to perform abdominal thrusts to see if he took water into his stomach.
D) Let's move him into the warm ambulance as quickly as possible, and then cut off his clothes and cover him.
