Final answer:
The husband should discuss a comfort-measures-only order with the physician, which focuses on palliative care without pursuing aggressive treatments, honoring the patient's end-of-life wishes.
Step-by-step explanation:
The husband of a terminally ill patient should speak to the physician about a comfort-measures-only order. This type of order aligns with the patient's wishes to not receive aggressive treatment that would merely prolong the process of dying. Instead, comfort-measures-only focuses on providing care that ensures the patient's comfort and peace in the last stages of life, which is in line with the principles of hospice care. A comfort-measures-only approach often includes pain relief and other measures to reduce discomfort without pursuing curative treatments.
