Final answer:
The statement is an example of clarifying in the context of patient data collection, as it seeks to eliminate confusion and confirm the healthcare professional's understanding of when the pain occurs.
Step-by-step explanation:
The method of patient data collection represented by the statement "So let me see if I understand; The pain only occurs at night." is clarifying. This approach is taken to ensure that there is a clear understanding of the patient's symptoms without any ambiguity. The healthcare professional is specifically asking for more details about the timing of the symptoms to make an accurate assessment and tailoring further questions based on the patient's response. By restating what has been said and seeking confirmation, the professional is also ensuring that both the patient and healthcare provider are on the same page before proceeding.
