Correct Answer: A

Rationale: The correct answer is A: Watson's philosophy and science of caring and humanistic nursing. This theory emphasizes the importance of the nurse-client relationship, caring, and holistic care. In this scenario, obtaining a guide dog for the client reflects the nurse's caring actions to promote the client's independence and well-being. By helping the client cope with the handicap and continue daily activities, the nurse embodies the essence of caring and humanistic nursing. Incorrect Choices: B: Mishel's uncertainty in illness - This theory focuses on how individuals respond to uncertainty in illness situations, which does not directly apply to the scenario of obtaining a guide dog for a blinded client. C: Orem's self-care deficit - This theory emphasizes the nurse's role in assisting clients with self-care activities when they are unable to do so independently. While related to the scenario, it does not capture the essence of caring and humanistic nursing demonstrated in the client's situation. D: Rogers' science of unitary human beings - This

Correct Answer: C

Rationale: The correct answer is C: case manager, according to Peplau's interpersonal relations model. In this scenario, the nurse is coordinating resources and services for the client, which aligns with the role of a case manager. Peplau's model emphasizes the therapeutic relationship between the nurse and client, focusing on understanding the client's needs and providing support. The nurse in this situation is not just providing direct care (caregiver), advocating for change (change agent), or focusing solely on cultural aspects (translator). The nurse's role as a case manager involves addressing the client's complex needs, coordinating care, and advocating for the client's well-being, making it the most appropriate choice in this context.

Correct Answer: B

Rationale: The correct answer is B: infection control. In this scenario, the nurse is focusing on preventing and controlling the spread of hospital-acquired diarrhea among pediatric patients. By investigating the incidence rates and implementing measures to reduce the risk of infection transmission, the nurse is fulfilling the role of infection control. Quality management (A) focuses on improving processes and outcomes, not specifically on infection prevention. Occupational health (C) involves ensuring workplace safety for employees, not patient infection control. Forensics (D) involves investigating and analyzing evidence related to crimes or legal matters, not infection control in a healthcare setting.

Correct Answer: D

Rationale: The correct answer is D: delegation of client care tasks. A team leader nurse can be held negligent for improper delegation as they are responsible for assigning tasks to appropriate staff ensuring safe and effective care. This is crucial for patient safety. Choices A, B, and C are incorrect because inadequate training, lack of policies, and failure to discipline unsafe workers are not directly related to the nurse's role in delegation and immediate patient care responsibilities.

Correct Answer: A

Rationale: The correct answer is A: Work with the patient and family to create an advanced plan of care. This is the best way to avoid ethical dilemmas because it involves proactive decision-making and communication among all parties involved. By creating an advanced plan of care, the patient and family can outline the patient's preferences, values, and goals for future care, ensuring that decisions align with the patient's wishes. This helps prevent potential conflicts and ensures that everyone is on the same page regarding the patient's care. Choices B, C, and D are incorrect: B: Explaining cognitive decline does not directly address how to avoid ethical dilemmas and may cause unnecessary distress. C: Discussing religious and spiritual concerns is important but may not specifically address future ethical dilemmas related to care decisions. D: Identifying family members in control of decision-making does not necessarily prevent ethical dilemmas and may overlook the patient's autonomy and preferences.
