Final answer:
The statement requiring follow-up is the one dismissing the importance of critical thinking in routine patient care, as critical thinking is crucial in all nursing tasks.
Step-by-step explanation:
The statement made by a nursing student that requires follow-up by the nursing instructor is "Critical thinking is not really necessary for routine patient care." This statement is incorrect as critical thinking is essential in all aspects of patient care, even routine tasks, to ensure safe and effective delivery of care. Critical thinking involves the application of knowledge, evidence-based practice, and clinical judgment to provide high-quality care. It requires nurses to constantly assess and reassess the needs of the client and make decisions based on the best available evidence and their professional expertise.
