A nurse identifies ways he/she can improve performance. He/she reflects on his nursing experiences. This is an example of the core critical thinking skill:

Correct Answer: A

Rationale: Self-regulation in critical thinking involves monitoring and improving one's performance through reflection on experiences, identifying strengths and weaknesses. A nurse reflecting on past care to enhance future practice exemplifies this e.g., adjusting communication after a patient misunderstanding. Analysis breaks down data (e.g., lab results), not necessarily reflecting on personal performance. Inference draws conclusions from evidence (e.g., diagnosing from symptoms), not self-improvement. Explanation justifies actions (e.g., why a drug was given), not introspective growth. Self-regulation's focus on self-assessment and correction aligns with the nurse's reflective process, fostering continuous professional development, a vital skill in nursing for adapting to challenges and ensuring high-quality, patient-centered care over time.
