Hospital Corpsman Basic (HCB) Test 5 Practice 2025 – Comprehensive All-in-One Guide to Exam Success

The correct answer is Penrose drain tubing. This type of tubing is specifically designed for medical use and is commonly utilized in surgeries and wound care to allow for fluid drainage. Its flexibility and appropriate width make it suitable for use as a tourniquet. When applied properly, Penrose drain tubing can effectively restrict blood flow by applying pressure to the limb it encircles.

In contrast, the other options are less suitable for this purpose. Silicone tubing, while flexible and durable, does not provide the necessary rigidity and pressure required for a tourniquet. Plastic straws lack the width and strength to effectively restrict blood flow, making them unsuitable for this medical function. Lastly, latex snacks may refer to latex gloves or items that are not designed for use as a tourniquet; thus, they would not be capable of applying the required pressure to restrict blood flow.
