Q. A 37-year-old woman is brought to the ER because of confusion and impaired consciousness. She was running, tripped on "black ice" and hit her head on the pavement. She lost consciousness for a few minutes, based on what her running watch shows (although she isn't certain). His temperature is 37.6 °C , HR is 70 beats/ minutes, BP is 125/90, and RR is 12 breaths/minutes. On exam, she is alert and oriented but delayed in her responses. During the evaluation you notice some clear liquid draining from her nose. On otoscope exam there is a blue-black discoloration to the tympanic membrane. Which of the following is true regarding management of this condition?
