Correct Answer: A

Rationale: The correct answer is A: Allowing nurses to work flexible shift durations. This strategy is important in addressing issues associated with the aging workforce because it acknowledges the changing needs and preferences of older nurses. By offering flexible shift durations, older nurses can better manage their work-life balance, reduce physical strain, and continue contributing to the workforce effectively. Choices B, C, and D are incorrect because they do not directly address the specific needs of the aging workforce. Encouraging older nurses to transfer to a less stressful outpatient setting may not align with their career goals. Hiring nurse technicians to assist with patient care may not address the unique experience and expertise of older nurses. Developing a staffing model, while important, does not specifically cater to the needs of aging nurses in terms of flexibility and support.

Correct Answer: A

Rationale: The correct answer is A: Bilateral infiltrates on chest x-ray study. ARDS diagnosis requires bilateral infiltrates on chest x-ray, indicative of non-cardiogenic pulmonary edema. Choice B, decreased cardiac output, is not a diagnostic criterion for ARDS. Choice C, PaO2/FiO2 ratio of less than 200, is a key diagnostic criteria for ARDS, indicating severe hypoxemia. Choice D, PAOP of more than 18 mm Hg, is used to differentiate between cardiogenic and non-cardiogenic causes of pulmonary edema, but it is not a direct diagnostic criterion for ARDS.

Correct Answer: C

Rationale: The correct answer is C: Responding to diversity. By considering the patient's gender, ethnicity, spirituality, and lifestyle, the nurse is focusing on responding to diversity in patient care. This approach acknowledges and respects the unique characteristics and backgrounds of individual patients, leading to more culturally competent and effective care. Choice A: Becoming a moral advocate does not directly relate to considering diversity in patient care. It involves standing up for ethical principles and values in healthcare. Choice B: Facilitating all forms of learning is not specific to addressing diversity in patient care. It pertains to promoting education and understanding in various learning styles. Choice D: Using effective clinical judgment is important in nursing practice but does not specifically address the focus on diversity in patient care. It pertains to making sound decisions based on clinical knowledge and expertise.

Correct Answer: B

Rationale: The correct answer is B: Art therapy. Art therapy can help critically ill patients express emotions, reduce anxiety, and cope with pain in a nonverbal way. It provides a creative outlet for self-expression and can improve overall well-being. Anaerobic exercise (A) may not be suitable for critically ill patients due to physical limitations. Guided imagery (C) may not be effective for all patients and requires a certain level of cognitive ability. Music therapy (D) can be beneficial, but art therapy is specifically known for its effectiveness in addressing emotional and psychological needs in critically ill patients.

Correct Answer: D

Rationale: The correct answer is D: Identify the problem. This is the first action the nurse should take in the nursing process as it helps in understanding the client's issue. By identifying the problem, the nurse can gather more information through further assessment to determine the underlying cause of the client's difficulty in walking. This step is crucial for developing an effective care plan and interventions. A: Predict the likelihood of the outcome - This choice is not appropriate as predicting the outcome should come after identifying the problem and implementing interventions. B: Consider alternatives - While considering alternatives is important in the decision-making process, it is not the immediate action needed in this scenario. C: Choose the most successful approach - This choice is premature as the nurse needs to first identify the problem before determining the most successful approach.
