Final answer:
A nurse who consistently follows instructions without question might be perceived as lacking in critical thinking, as nursing requires making independent decisions, often involving questioning and verification to ensure patient safety.
Step-by-step explanation:
An action that would lead a nurse to believe a coworker is not a good critical thinker could be if they consistently follow the charge nurse's directions without question. Critical thinking in nursing involves assessing situations and making independent decisions, which sometimes means questioning instructions when they do not seem to be in the best interest of the patient. This is different from a nurse who asks many questions when dealing with new situations, one who admits to not knowing everything, or another who verifies the meaning of communication to ensure understanding; these behaviors are typically associated with good critical thinking because they demonstrate an eagerness to learn, understand thoroughly, and avoid making unnecessary mistakes.
