Final answer:
The nurse should advise the mother to keep the twins home from the wake and let them attend the funeral.
Step-by-step explanation:
The therapeutic response that the nurse should provide is option D: 'It's a difficult decision, but given their young age, maybe it would be best to keep them home from the wake and just let them attend the funeral.'
This response acknowledges the mother's concern and acknowledges the differing opinions. It also considers the age and emotional capacity of the twins and suggests a compromise that allows them to attend the funeral while protecting them from the potentially overwhelming experience of the wake.
