A 54-year-old male accidentally shot himself in the leg while cleaning his gun. Your assessment reveals a small entrance wound to the medial aspect of his right leg.

You should: A. control the bleeding and cover the wound with a sterile dressing. B. manually stabilize the leg above and below the site of injury. C. gently manipulate the injured leg until the numbness dissipates. D. assess distal pulses as well as sensory and motor functions.

A. control the bleeding and cover the wound with a sterile dressing. Chapter 31, page 1103, Emergency Medical Care

B. make one attempt to return the patella to its normal position. C. flex her knee slightly more and assess for distal circulation. D. gently straighten her knee and apply a padded board splint.

A. keep her knee flexed and secure it with padded board splints. Chapter 31, page 1129, Specific Musculoskeletal Injuries

A 22-year-old female was ejected from her car after striking a tree head-on. As you approach her, you note obvious closed deformities to both of her femurs. She is not moving and does not appear to be conscious. You should: A. administer oxygen and perform a rapid assessment. B. stabilize her head and perform a primary assessment. C. assess for a carotid pulse and assist her ventilations. D. apply manual stabilization to both of her femurs.

During your secondary assessment of a 30-year-old male who fell 25 feet, you note crepitus when palpating his pelvis. Your partner advises you that the patient's blood pressure is 80/50 mm Hg and his heart rate is 120 beats/min and weak. After completing your assessment, you should: A. log roll the patient onto a long backboard and transport at once. B. stabilize the pelvis with a pelvic binder and protect the spine.
