Your patient has fallen in her kitchen and has a possible sprained ankle. As you proceed through your history and physical exam, you notice that she has an altered mental status and is not answering your questions appropriately. She is alone in the house and you are unable to determine the circumstances of her fall. Her blood pressure is 140/78, pulse 110, respiration rate 22, and she is cool, pale, and diaphoretic. You have determined that she has a patent airway and no immediate life threats. What should you do next?
a. Immobilize her spine with a long spine board.
b. Have her stabilize her ankle while you splint it.
c. Perform further assessments to determine why she fell.
d. Check her ankle for other injuries.
