Signs and symptoms that might be found in a patient who has experienced a concussion include:

• A. Tachycardia and diaphoresis
• B. Nausea and ringing in the ears
• C. Hypotension and nosebleed
• D. Anxiety and restlessness

Answer: (B)

A patient who has experienced a concussion may present with a variety of signs and symptoms that reflect the impact of the injury on the brain. Nausea and ringing in the ears, also known as tinnitus, are common symptoms associated with concussion due to the disruption of normal brain function. When the brain suffers trauma, it can lead to both physical and neurological changes, which may manifest as gastrointestinal distress like nausea and auditory disturbances such as ringing in the ears. Understanding the physiology behind these symptoms is crucial. The brain's response to injury can trigger a cascade of physiological processes, including alterations in neurotransmitter levels, which can impact sensory perception and lead to feelings of nausea. Similarly, the vestibular system, which helps with balance and spatial orientation, can be affected by concussion, resulting in auditory disturbances. The other options listed present symptoms that are not typically associated with concussive injuries. While anxiety and restlessness can sometimes be seen after a concussion due to the emotional stress of the injury, they are not direct symptoms like nausea and tinnitus, which are more specific to the brain's response to the trauma.
