A 60-year-old widower is hospitalized after complaining of difficulty sleeping, extreme apprehension, shortness of breath, and a sense of impending doom. What is the best response by the nurse?

Choice B is the best response as it shows empathy, acknowledges the patient's feelings, and opens the door for discussion about potential triggers for anxiety. This approach helps the patient explore the root cause of his anxiety and provides an opportunity for therapeutic communication. Choice A dismisses the patient's feelings and offers false reassurance, which may not address the underlying issue. Choices C and D do not encourage the patient to express his emotions or delve into the reasons behind his anxiety, hindering the therapeutic process.
