Where should Joe perform a focused check based on Nick's answers and his observations?

In this scenario, performing a focused check on the right arm and elbow is appropriate based on Nick's answers and Joe's observations. A focused check is often carried out to assess specific areas that may be injured or affected based on the symptoms or issues highlighted during the primary assessment and the victim's responses.

If there are indications such as visible swelling, pain, or difficulty moving the right arm, conducting the examination in that area allows Joe to gather important information that might lead to identifying an injury or assess the severity of a situation. Paying attention to the elbow and arm could also reveal any issues related to a potential fracture or dislocation, which would be relevant to appropriate care and any necessary interventions.
