Tani Becker is a 23-year-old college student majoring in equine studies. Tani has been riding horses since she was 5 years old. This evening, the equine team is practicing for the upcoming competition with events in barrel racing, pole bending, keyhole, showmanship, and trail classes. Tani does not have her helmet with her. She tells her friend she inadvertently left her helmet in the car and her sister has taken the car to work. Tani knows the team policy states that the members must wear protective headgear while riding; she has always worn a helmet. Her riding coach is teaching a class and is not at the practice. With the pressure of the upcoming competition, Tani decides to practice just this one time without a helmet. As she was rounding her first barrel, the horse swerves quickly, throwing her off. Tanis vital signs remain stable. She is drowsy, but easily aroused. She continues to complain of a headache. Which assessment findings would you need to report to the health care provider immediately?
