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?

Ask the client to provide a detailed description about the quality of the pain.

Review the medication record and note when the client last received an analgesic.

Compare the client's current vital signs with vital signs taken earlier in the day.

Consult with the charge nurse about the manifestations that the client is exhibiting.
