The nurse is assessing an older adult client at a hospice unit. The client cannot speak or communicate, but the client's daughter is there and answers all the questions as best as she can. What type of data source is the daughter?

A. Subjective: Subjective data refers to information reported by the patient directly, which is not applicable in this case since the client cannot communicate. B. Tertiary: This term is not commonly used in the context of data sources in health assessments. C. Secondary: Secondary data is information provided by someone other than the patient, such as a family member or caregiver, which is applicable here since the daughter is providing the information. D. Primary: Primary data is directly obtained from the patient, not from a secondary source like the daughter.
