The practical nurse (PN) observes a male client grimacing and holding his head. The PN determines that the client is in pain. To validate this assessment with subjective data, which action should the PN implement?

A. Ask the client to provide a detailed description about the quality of the pain: Subjective data are obtained directly from the client’s verbal report. Asking the client to describe the pain’s quality, intensity, and location validates the nurse’s observation and provides essential information for accurate pain assessment and management. B. Review the medication record and note when the client last received an analgesic: This provides objective data about pain management but does not validate the client’s current pain experience, which must come from the client’s own report. C. Compare the client’s current vital signs with vital signs taken earlier in the day: Changes in vital signs, such as increased pulse or blood pressure, are objective indicators of pain, but they cannot confirm the client’s subjective experience. D. Consult with the charge nurse about the manifestations that the client is exhibiting: Discussing observations with another nurse may be appropriate later, but validation of pain requires direct communication with the client, not secondary consultation.
