Final answer:
The most appropriate response by the nurse is option C) "I understand your concerns; it's important to discuss your symptoms further. Have you experienced other signs of distress or avoidance?"
Step-by-step explanation:
The most appropriate response by the nurse to a patient who complains of nightmares and expresses concerns about having PTSD after a car accident more than 4 weeks ago is option C) "I understand your concerns; it's important to discuss your symptoms further. Have you experienced other signs of distress or avoidance?"
Choosing this response shows empathy and acknowledges the patient's concerns while also indicating the need for further assessment and exploration of possible symptoms of PTSD. It allows the nurse to gather more comprehensive information and provide appropriate support and guidance to the patient. Options A, B, and D either downplay the patient's concerns or offer simplistic solutions without considering the possibility of PTSD.
