Which term refers to a physical restraint that compresses the neck to cause a brief loss of consciousness?

• A. Umbilical Cord
• B. Vascular Neck Restraint
• C. ABC
• D. Water Based

Answer: (B)

The term describes a restraint technique that works by applying pressure to the neck to restrict blood flow to the brain, causing a brief loss of consciousness. This is specifically a vascular neck restraint, where the goal is vascular occlusion rather than blocking the airway. That mechanism—compressing the neck to reduce cerebral perfusion for a short period—is what defines this option.

The other choices don’t fit because they refer to unrelated ideas: one is an anatomical structure of a fetus, another is an acronym that isn’t about restraints, and the last is something not associated with restraint at all. So the term that matches the description of compressing the neck to induce a brief loss of consciousness is vascular neck restraint.
