What this topic is really about
Direct pressure is the standard first-line intervention to control external hemorrhage by compressing the bleeding vessels. Applying a tourniquet immediately is incorrect because a tourniquet is typically reserved for catastrophic extremity bleeding when direct pressure fails to control the hemorrhage.
Suspected spinal injuries require immediate manual stabilization and immobilization to prevent movement of unstable vertebrae, which can cause permanent spinal cord damage. Allowing the patient to walk or sit up risks exacerbating the injury and must be avoided until the spine is fully cleared.

An exam-style question, fully explained
A patient with suspected spinal injury should be:
- Identify what the question tests: A patient with suspected spinal injury should be:.
- Suspected spinal injuries require immediate manual stabilization and immobilization to prevent movement of unstable vertebrae, which can cause permanent spinal cord damage.
- Allowing the patient to walk or sit up risks exacerbating the injury and must be avoided until the spine is fully cleared.
Traps the examiner sets
- Applying a tourniquet immediately is incorrect because a tourniquet is typically reserved for catastrophic extremity bleeding when direct pressure fails to control the hemorrhage.
- While a single arm adds 9% to total 45%, options like 18% are incorrect because they only account for a single leg, leaving 36% as the most accurate base calculation for the lower extremities.
