Written Lifeguarding Practice Test

The term "rescue tube" specifically refers to a flotation device that lifeguards utilize to assist distressed swimmers or during rescues. This device is designed for ease of use in emergency situations, offering both support to the individual in distress and a means for the lifeguard to safely reach and retrieve them from the water.

The rescue tube typically has a long, tubular shape filled with air, allowing it to provide buoyancy and stability in the water. It also usually features a strap or rope, which the lifeguard can use to secure the tube to both themselves and the person being rescued, ensuring that assistance is both effective and safe.

Other options, such as life jackets which are primarily worn by swimmers for personal flotation and safety, do not fall under the definition of a rescue tube since they are meant for individual use, not for rescue purposes. Similarly, devices that decrease buoyancy do not relate to the role of supporting a distressed swimmer, as the focus of a rescue tube is to provide maximum buoyancy. Lastly, tools used for measuring water temperature do not pertain to rescues, as they serve a completely different function unrelated to flotation or assistance.
