In the situation where a lifeguard witnesses a drowning but is alone, the most effective course of action is to call for help and attempt to provide assistance until backup arrives. The correct answer emphasizes the importance of immediately alerting emergency services and ensuring that professional help is on the way.

The rationale behind this approach lies in the need for safety and effectiveness during a rescue. Jumping in straight away without a backup can create additional risks, as the lifeguard may also find themselves in danger, which can complicate rescue efforts further. Using a rescue pole is a viable option but may not always be feasible depending on the circumstances and the distance from the victim. While performing CPR is critical for a drowning victim once they are out of the water and not breathing, it is essential to first ensure that the victim is safely retrieved and that emergency services are notified, as CPR cannot be performed effectively without first addressing the airway and breathing issues in a safe environment.

Therefore, the correct procedure for a lifeguard who is alone and witnesses a drowning involves a systematic approach of calling for help and preparing to assist until trained professionals can take over the rescue, ensuring the safety of both the rescuer and the victim.
