Final answer:
In example 4, the nurse is not applying critical thinking skills by simply explaining a procedure without considering potential problems or evaluating the situation critically.
Step-by-step explanation:
In the given examples, the nurse is not applying critical thinking skills in practice in example 4: The nurse explains the procedure for giving a tube feeding to a second nurse who has floated to the unit to assist with care.
This is because in this example, the nurse is simply providing information without considering any potential problems or evaluating the situation critically. The nurse is not actively analyzing the procedure or thinking about alternative solutions or potential complications.
In contrast, in the other examples, the nurse demonstrates critical thinking skills by considering personal experience and ways to improve in example 1, using a fall risk inventory scale to determine fall risk in example 2, and observing a change in behavior and considering potential problems in example 3.
