Final answer:
The best nurse response to the patient's expression of a lack of interest in work, no energy, inability to eat or sleep would be 'a. It sounds like you have lost hope,' because it addresses the overall feeling of despair encompassing all symptoms.
Step-by-step explanation:
The question is asking which response by the nurse would be best when a patient with a terminal illness expresses a lack of interest in work, no energy, and difficulty with eating and sleeping. The best response is to address the patient's overall feeling of hopelessness, which encompasses all the symptoms mentioned. Although each option provided seems to highlight a symptom, the nurse's best response would acknowledge the underlying loss of hope which is a naturally common reaction to terminal illness and captures the essence of the patient's feelings.
Therefore, the correct answer is:
a. It sounds like you have lost hope.
