In a knee replacement patient, which of the following is an example of subjective data?

• A. The client's pain is a 7 on a scale of 1-10
• B. The client's heart rate is 78 bpm
• C. The incision is 12 cm long
• D. The wound edges are clean and dry

Answer: (A)

Understanding subjective vs objective data is the key idea here. Subjective data are reports or sensations that come from the patient and can’t be measured directly by you. In this scenario, the patient saying their pain is a seven out of ten is a personal experience the patient is describing, so it’s subjective data. The other items are objective data: heart rate is a measurable vital sign, incision length is a physical measurement, and the wound edges being clean and dry are observable findings. Recognizing this distinction helps you prioritize how to respond—subjective data guide questions and pain management, while objective data provide concrete measurements to monitor changes.
