Step-by-step explanation:
The best question for the nurse to use to assess the adaptation to pregnancy by the father-to-be is 'How are you feeling about becoming a father?'
As the father-to-be is an important part of the pregnancy experience, it is important for the nurse to understand his emotions, concerns, and expectations about becoming a father. This question allows the nurse to gather information about the father-to-be's feelings, which can help identify any potential support or education needed.
