ANS: C
Patients' feelings about a situation or comments about how they are feeling are examples of subjective data. Data shared by a source verbally are considered subjective. Subjective data may be difficult to validate because they cannot be independently and objectively measured. Data collected from medical records, laboratory, and diagnostic test results, or physical assessments are objective. Objective data (i.e., signs) consist of observable information that the nurse gathers on the basis of what can be seen, measured, or tested. Subjective data (i.e., symptoms) are spoken. Primary data consist of information obtained directly from a patient. Secondary data are collected from family members, friends, other health care professionals, or written sources such as medical records and test results.
