Final answer:
The most appropriate next action is to prioritize the patient's emotional well-being and provide psychological support.
Step-by-step explanation:
The most appropriate next action in this situation is to prioritize the patient's emotional well-being and provide psychological support.
Option A is not the most appropriate next action because performing a full trauma assessment is not necessary for a patient who does not appear to be seriously injured.
Option B is not the most appropriate next action because obtaining vital signs and asking about transport should come secondary to addressing the patient's emotional needs.
Option C is not the most appropriate next action because fully immobilizing the patient's spine and transporting her to a trauma center is excessive for a patient with only a small abrasion to the forehead.
Option D is not the most appropriate next action because performing a focused exam on the patient's forehead is not a priority compared to addressing the emotional impact of her husband's death.
