A soldier on his second tour of dutywas notified of the date that he will be redeployed. As this date approaches, he is showing signs of excess anxiety and irritability and inability to sleep at night because of nightmares of IED (improvised explosive devices) tragedies, all leading to poor work performance. His commanding officer refers him to the base hospital for an evaluation. The admitting nurse should take the following actions in order of priority from first to last?
