Validation is the process of verifying the data to ensure that it is accurate and factual. One way to validate observations is through “double-checking,” and it allows the nurse to complete the following tasks:

1. Ensures that assessment information is double-checked, verified, and complete.
   For example, during routine assessment, the nurse obtains a reading of 210/96 mm Hg of a client with no history of hypertension. To validate the data, the nurse should retake the blood pressure and if necessary, use another equipment to confirm the measurement or ask someone else to perform the assessment.
2. Ensure that objective and related subjective data are valid and accurate.
   For example, the client’s perceptions of “feeling hot” need to be compared with the measurement of the body temperature.
3. Ensure that the nurse does not come to a conclusion without adequate data to support the conclusion.
   A nurse assumes tiny purple or bluish-black swollen areas under the tongue of an older adult client to be abnormal until reading about physical changes of aging.
4. Ensure that any ambiguous or vague statements are clarified.
   For example, a 86-year-old female client who is not a native English speaker says that “I am in pain on and off for 4 weeks,” would require verification for clarity from the nurse by asking “Can you describe what your pain is like? What do you mean by on and off?”
5. Acquire additional details that may have been overlooked.
   For example, the nurse is asking a 32-year-old client if he is allergic to any prescription or non-prescription medications. And what would happen if he takes these medications.
6. Distinguish between cues and inferences.
   Cues are subjective or objective data that can be directly observed by the nurse; that is, what the client says or what the nurse can see, hear, feel, smell, or measure. On the other hand, inferences are the nurse’s interpretation or conclusions made based on the cues. For example, the nurse observes the cues that the incision is red, hot, and swollen and makes an inference that the incision is infected.
