Correct Answer: C

Rationale: The correct answer is C. A sentinel event in healthcare is an unexpected patient death unrelated to the natural course of illness. These events are serious occurrences that warrant immediate investigation and response to prevent their recurrence and ensure patient safety. Choices A, B, and D do not fit the definition of a sentinel event. A patient falling without injury, a near-miss medication error, and a patient developing an infection, while concerning, do not meet the criteria of an unexpected patient death unrelated to the natural course of illness.

Correct Answer: D

Rationale: Arriving for class on time and prepared is the correct way for a student to demonstrate care for classmates. This action shows respect for their peers' time and contributes positively to the learning environment. Being punctual and ready for class helps create a conducive atmosphere for everyone's learning and demonstrates consideration for classmates. Choices A, B, and C do not directly show care for classmates. Choice A focuses on individual preparation, Choice B involves the instructor but not classmates, and Choice C reflects negative behavior that does not benefit classmates.

Correct Answer: B

Rationale: Motivation is commonly described as a fluid and dynamic process that evolves and changes over time. It is not stagnant but rather fluctuates based on various internal and external factors. Choice A is incorrect as motivation is not stagnant but dynamic. Choice C is incorrect as motivation does not necessarily require great force to change. Choice D is incorrect as motivation is not something that differs drastically every day, but rather changes gradually over time.

Correct Answer: A

Rationale: If the informal discussion between the nurse and nurse manager does not resolve the issue regarding the physician's report on the nurse's performance, the nurse can submit a written appeal within 10 days, according to the health care facility policy. This 10-day timeframe ensures a prompt resolution of disputes and maintains clear communication channels within the healthcare setting. Choices B, C, and D are incorrect as they exceed the time limit allowed for the nurse to submit an appeal, which is specified to be 10 days.

Correct Answer: C

Rationale: Dorothea Dix is the correct answer. She is recognized for her significant contributions in advocating for the improvement of care for the mentally ill. Dix played a crucial role in establishing mental health institutions and reforming the care provided to individuals with mental health conditions. While Clara Barton is known for founding the American Red Cross, Florence Nightingale is renowned as the founder of modern nursing, and Lillian D. Wald is recognized for her work in public health nursing, none of them are specifically honored for their work in improving care for the mentally ill in mental health nursing.
