A nurse is assessing a client following a wound debridement. Which of the following subjective data indicates a need for the administration of PRN pain medication?

Subjective data is information reported or described by the client — what they say or demonstrate about their experience. Grimacing upon movement is a nonverbal behavioral indicator of pain from the client (subjective). Diaphoresis, tachycardia, and elevated blood pressure are objective findings (measurable data collected by the nurse). While all of these can indicate pain, only grimacing — a client behavior — is subjective data.
