Correct Answer: A

Rationale: The correct answer is A: Caring for an aging population. This is a uniquely twenty-first-century issue as advancements in healthcare have increased life expectancy, leading to a larger elderly population with complex healthcare needs. Nurses must adapt their skills and knowledge to provide specialized care for this demographic. B: Increased patient acuity is a common challenge but not unique to the twenty-first century. Nurses have always dealt with varying levels of patient acuity. C: Access to health care services is an ongoing issue that has been prevalent for many years, not specifically unique to the twenty-first century. D: Expanding technology is also a significant challenge for nurses in the modern era, but it is not uniquely a twenty-first-century issue as technology has been advancing for decades.

Correct Answer: D

Rationale: The correct answer is D: Biofeedback. Biofeedback is a type of CAM that involves using electronic devices to help individuals gain awareness and control over physiological processes, such as heart rate and muscle tension. In this case, the older adult is using imagery as a form of biofeedback to alter the dysrhythmia. Ayurveda (A) and Dosha (B) are traditional Indian systems of medicine based on balancing bodily energies, not directly related to using imagery for heart rhythm control. Homeopathy (C) is a system of alternative medicine based on the concept that "like cures like" and uses highly diluted substances, not imagery or biofeedback techniques.

Correct Answer: D

Rationale: The correct answer is D because it demonstrates the use of telehealth in monitoring and providing remote care to a patient. In this scenario, a nurse is able to supervise and ensure the correct execution of peritoneal dialysis by observing the patient from a different location. This exemplifies the practical application of telehealth in enhancing patient care and safety. Choice A is incorrect because it describes a robot performing housekeeping chores, which is not directly related to telehealth or patient care. Choice B is incorrect as it focuses on computer software alerting about drug interactions, but it does not involve remote patient care or monitoring. Choice C is incorrect as it describes a physician dictating an admission history, which is not a direct example of telehealth involving remote patient monitoring or care.

Correct Answer: C

Rationale: The correct answer is C: Connection. The nurse's power comes from her ability to network and build relationships with influential individuals like the Chief of Medical Staff and the President of the hospital. This grants her access to information, resources, and opportunities not available to others. This power is based on who she knows rather than her expertise (A), position (B), or ability to offer rewards (D). The nurse's statement implies that her influence stems from her connections, making choice C the most appropriate answer.

Correct Answer: B

Rationale: The correct answer is B: stop the LPN/LVN immediately and discuss the possible consequences of his actions in a nonjudgmental manner. This is the priority intervention because it addresses the immediate issue of potentially incorrect documentation and allows for clarity and understanding between the RN and LPN/LVN. It promotes open communication and a chance to correct any errors that may have occurred. Choice A is incorrect because checking the drug packages after the fact does not address the issue of potentially incorrect documentation and missed medications. Choice C is incorrect as it is an extreme response that does not promote a collaborative and educational approach to resolving the situation. Choice D is incorrect as calling the pharmacy for replacement medications is not necessary at this stage and does not address the immediate concern of potentially incorrect documentation.
