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

Subjective data comprises client perceptions, feelings, and self-reported symptoms that cannot be independently observed or verified by a clinician. These manifestations reflect the patient's internal physiological and psychological state, captured through active communication. In contrast, objective data represents measurable, reproducible clinical signs obtained through physical examination or laboratory testing. A. Client reports nausea following administration of pain medication.: Nausea is an internal, visceral sensation of gastrointestinal distress that cannot be visually measured or verified by an examiner. It relies entirely on the patient's verbal description of their comfort level. This self-reported symptom represents classic subjective data. B. Client's oral temperature is 38.4° C (101.2° F).: Body temperature measured via a calibrated thermometer provides an empirical, reproducible quantification of core heat levels. It represents a clinical sign that can be independently verified by any healthcare practitioner. This constitutes objective biometric data. C. Client reports the rash on their back is itchy: Pruritus is a subjective neurocutaneous sensory perception that only the affected individual can feel and describe. While the rash itself is visible, the accompanying sensation of itchiness cannot be objectively measured. It remains a subjective symptom. D. Client reports dull, aching pain in lower right calf.: Pain is a highly individualized, multi-dimensional sensory and emotional experience lacking direct empirical measurement tools. The location, quality, and severity of the discomfort rely completely on the patient's personal report. It is categorized as subjective data. E. Client has a raised, red rash on their upper back.: A localized cutaneous eruption characterized by erythema and structural elevation is directly visible and quantifiable during a physical examination. The nurse can document its specific anatomical dimensions, layout, and color. This physical finding represents objective data.
