Client perceptions about their health problems are:

Correct Answer: D

Rationale: Subjective data are clients' perceptions e.g., 'I feel dizzy' reported directly, capturing experiences unmeasurable by others. This contrasts with objective data (e.g., pulse), observable by nurses. Observational recordings are objective, like noting pallor, not perceptions. Ancillary reports (e.g., lab results) are objective, external data, not client-voiced. Subjective data's focus on personal input e.g., pain severity enriches assessment, guiding nurses to explore symptoms' impact (e.g., anxiety's role), making it vital for holistic care and the correct classification here.
