Final answer:
Nurses are responsible for analyzing and interpreting data to make a nursing diagnosis, an essential step in creating a personalized care plan.
Step-by-step explanation:
The person responsible for analyzing and interpreting data to arrive at a nursing diagnosis is the nurse. The nursing diagnosis is a critical component of the nursing process, which is a systematic approach nurses use to provide patient care. Nurses gather data through assessment, which they then analyze and interpret to determine the patient's health status and identify any potential or actual health issues. Based on this analysis, nurses formulate a nursing diagnosis that guides the development of a care plan tailored to the patient's specific needs.
