A nurse at an urgent care center is reinforcing information with a new employee about the difference between sprains and strains. Which of the following examples should the nurse include as a cause of sprain injury?

A. Impact injury on a joint from a fall: Rationale: This may result in a fracture or contusion, not necessarily a sprain. A sprain involves ligament damage from stretching or twisting. B. Twisting a ligament while walking: Rationale: A sprain is an injury to a ligament, usually caused by twisting or overstretching a joint, like an ankle. C. Overusing a muscle while jogging: Rationale: This describes a strain, which is an injury to a muscle or tendon, not a ligament. D. Crush injury to a bone from blunt trauma: Rationale: This would more likely result in a fracture or soft tissue damage, not a sprain.
