The nurse is caring for a patient who was in a motor vehicle accident that resulted in cervical trauma to C4. Which assessment is the priority?

The correct answer is A: Respirations. Cervical trauma to C4 can affect the patient's ability to breathe due to potential impairment of the phrenic nerve. Assessing respirations is crucial as it could indicate compromised airway or respiratory function, requiring immediate intervention to prevent respiratory distress or failure. Pulse, temperature, and blood pressure are important assessments but are secondary to assessing respirations in this scenario. Pulse may be affected by the trauma, but not as immediately life-threatening as compromised respirations. Temperature and blood pressure may be affected by other factors but do not directly relate to the potential airway compromise in cervical trauma. Hence, prioritizing respiratory assessment is essential for prompt intervention and preventing respiratory complications.
