A nurse is documenting assessment findings on a client. Which of the following entries should the nurse identify as subjective data? (Select All that Apply.)

A) Client's oral temperature is 38.4°C (101.2°F): This is objective data, as it is a measurable, observable finding obtained through direct assessment (in this case, using a thermometer). Objective data are facts or measurements that can be verified or observed by the healthcare provider. B) Client reports the rash on their back is itchy: This is subjective data, as it is based on the client's personal experience and report. The feeling of itchiness cannot be directly measured or observed by the nurse; it is something the client experiences and describes. Subjective data include symptoms, sensations, or feelings reported by the client. C) Client reports nausea following administration of pain medication: This is subjective data. Nausea is a symptom that the client reports experiencing, which cannot be objectively measured or directly observed by the nurse. It is based on the client's perception and report, making it subjective. D) Client has a vesicular rash on their upper back: This is objective data. The rash is something the nurse can observe and describe. Objective data include observable facts, such as physical exam findings, lab results, or diagnostic test results. E) Client reports dull, aching pain in lower right calf: This is subjective data, as pain is a sensation that the client experiences and describes. The intensity, location, and type of pain (dull, aching) are subjective experiences that only the client can report.
