Correct Answer: C

Rationale: Recent polls have identified nursing as one of the most trusted professions due to nurses possessing the necessary skills to provide care for diverse populations. This includes understanding and addressing the unique needs of individuals from various backgrounds and cultures. Choice A is incorrect because while nurses do engage in lifelong learning, this is not the primary reason for their trustworthiness. Choice B is also incorrect as abiding by a dress code does not directly contribute to the trust placed in nurses. Choice D is incorrect because passing the NCLEX exam is a regulatory requirement for obtaining a license and does not solely determine the trustworthiness of nurses in the eyes of the public.

Correct Answer: B

Rationale: The correct answer is B. Amitriptyline is a tricyclic antidepressant that works by inhibiting the reuptake of serotonin and norepinephrine, which helps in reducing the transmission of pain impulses to the brain. Choice A is incorrect because amitriptyline primarily works on pain transmission rather than directly on depression. Choice C is inaccurate as amitriptyline's mechanism of action is not related to correcting blood vessel changes. Choice D is partially true as amitriptyline can improve sleep, but the primary mechanism related to pain relief is by preventing pain impulses from reaching the brain.

Correct Answer: B

Rationale: The correct answer is B. In palliative care, a nurse's primary role is to coordinate patient care and provide pain management. While emotional support (Choice A) is a crucial aspect of palliative care, it is not the primary role of a nurse in this setting. Administering medications and treatments (Choice C) is part of the nurse's responsibilities but not the primary role. Conducting research (Choice D) is important for advancing palliative care but is not the primary role of a nurse providing direct patient care in this context.

Correct Answer: C

Rationale: The essential element of a quality improvement (QI) program is continual monitoring. Continual monitoring allows for the ongoing assessment of processes, identification of areas for improvement, and tracking of progress. Option A, 'Blame and punishment,' is incorrect as QI programs focus on systemic issues rather than individual blame. Option B, 'Employee satisfaction,' while important for organizational culture, is not an essential element of QI programs. Option D, 'Strict adherence to policies,' is valuable but not the core essential element, which is continual monitoring to drive improvement.

Correct Answer: A

Rationale: Before a person becomes violent, observable behaviors may include tense shoulders, clenched fists, a blank stare, and being positioned with one foot in back and an arm pulled back. Wandering is not typically associated with threatening behaviors signaling imminent violence. DelBel (2003) suggests that strategies such as relaxed body language, maintaining physical distance, and silence can help de-escalate an agitated individual's response.
