Correct Answer: B

Rationale: The correct answer is B: Being a change agent. The manager is demonstrating the quality of being a change agent by implementing an initiative aimed at improving the unit's operations. A change agent initiates and drives changes to enhance effectiveness and efficiency within the unit. Choice A is incorrect because the manager's actions are not described as unrealistic but rather proactive. Choice C, being democratic, is incorrect as it does not relate to the manager's initiative to improve unit operations. Choice D, being authoritarian, is also incorrect as the manager is not described as enforcing changes through strict control and power.

Correct Answer: B

Rationale: The patient with a blood glucose level of 40 mg/dL (hypoglycemia) needs immediate attention as it is an emergency situation that requires prompt intervention to prevent adverse effects. Severe hypoglycemia can lead to serious complications, such as seizures or loss of consciousness. Therefore, the nurse should prioritize assessing and managing this patient first to prevent further deterioration. Choices A, C, and D do not present immediate life-threatening situations requiring urgent intervention like severe hypoglycemia does. A high hemoglobin A1C level, an abnormal oral glucose tolerance test result, and acute abdominal pain, while important, do not pose an immediate threat to the patient's life compared to severe hypoglycemia.

Correct Answer: B

Rationale: The principle of confidentiality requires nurses to hold healthcare information and anything patients tell them in the strictest confidence.

Correct Answer: A

Rationale: The correct answer is option A: 'Confirming that a client's pain has decreased after receiving an analgesic.' This task involves assessing the effectiveness of the medication, which can be delegated to the assistive personnel. Options B, C, and D involve skills that should be performed by licensed healthcare professionals due to their complexity and potential risks if not done correctly. Ambulating a postoperative client requires monitoring for signs of distress or complications, inserting a urinary catheter involves an invasive procedure with infection risks, and demonstrating the use of medical devices like an incentive spirometer requires specialized knowledge to ensure correct usage.

Correct Answer: C

Rationale: Valuing respect for the individual as defining high-quality patient care describes the nurse's paradigm, which is the overall way of thinking and approaching patient care that guides their actions and decisions. It reflects their fundamental beliefs and values regarding patient interactions and care delivery. Critical thinking involves analyzing information objectively and evaluating situations to make informed decisions. Caritas refers to acts of loving kindness and compassionate care in nursing practice. The hierarchy of needs is a theory that describes the hierarchical nature of human needs, such as physiological needs, safety needs, and social needs.
