Correct Answer: A

Rationale: When a client has vision loss, arranging food in a consistent pattern on the plate can help them locate and identify different food items more easily. This intervention promotes independence and allows the client to feed themselves with greater ease. Thicking liquids on the tray, providing small-handled utensils, or assigning a staff member to feed the client may not directly address the client's need for assistance with feeding due to vision loss. Thicking liquids is more related to swallowing difficulties, providing small-handled utensils can be helpful for clients with limited dexterity, and assigning a staff member to feed the client may not promote independence.

Correct Answer: A

Rationale: In this scenario, the nurse should include an interpreter in the discussion to facilitate clear and accurate communication between the nurse and the client who speaks a different language. The interpreter plays a crucial role in ensuring that the client fully understands the preoperative teaching and can express any concerns or questions effectively. Choice B, a social worker, is not the most appropriate option in this context as the primary need is language interpretation rather than social support. Choice C, an occupational therapist, is also not the best option as their role does not directly address the language barrier issue. Choice D, a spiritual advisor, is not relevant to the situation at hand and would not assist in overcoming the language barrier.

Correct Answer: C

Rationale: The correct answer is national healthcare legislation. This type of policy operates at a broad level, influencing healthcare delivery and financing across an entire nation. It sets overarching frameworks and regulations that impact various aspects of the healthcare system on a large scale, affecting a wide population rather than specific localities or institutions. Choices A, B, and D are not examples of macro-level health policy. Local health ordinances pertain to specific areas or communities, state licensing regulations focus on a state level, and institutional policies are internal regulations of a particular healthcare facility.

Correct Answer: C

Rationale: The correct answer is C: 'the length of the client's stay.' The length of the client's stay is a critical factor in determining the cost-effectiveness of care after hip arthroplasty. Shorter stays typically result in lower costs as they reduce resource utilization and associated expenses. Choices A, B, and D are not directly related to evaluating cost-effectiveness in this scenario. The age of the client, availability of community support groups, and the type of insurance carried may impact other aspects of care but do not directly assess the cost-effectiveness of the care provided.

Correct Answer: B

Rationale: The Medical Reserve Corps (MRC) is the correct answer. This group consists of local volunteers who have completed emergency response training and are able to assist in the triage of injured citizens. Additionally, they participate in local health fairs to educate residents on tornado response procedures. The other choices are incorrect: MMRS (Metropolitan Medical Response System) focuses on coordinating resources for mass casualty incidents, NDMS (National Disaster Medical System) is a federally coordinated system for medical response during disasters, and CCRF (Commissioned Corps Readiness Force) is part of a specific governmental service branch.
