1. This appeal stems from the Hinds County Circuit Courts grant of summary judgment in favor of Mississippi Baptist Medical Center (Baptist), based on the circuit courts finding that the plaintiff, Paula Vaughn, failed to establish a prime facie case of medical negligence. The trial court found that Vaughn had failed to establish the necessary element of proximate cause based on its finding that Vaughns designated expert, a nurse, was not qualified to testify as to whether the negligent acts of Baptist proximately caused Vaughns injuries. Moreover, the trial court declined to grant Vaughns Motion to Amend Rulings of the Court to allow Vaughn more time to designate another expert. Aggrieved, Vaughn appeals to us. Finding no error, we affirm.
