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

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.

Question the unlicensed assistive personnel about the client's expression of pain.

Ask the client to rate the pain being experienced using a ten-point numeric scale.
