Correct Answer: B

Rationale: The correct response is to provide oxygen through a tube in the client's nose. Oxygen therapy can offer comfort and support breathing without being considered resuscitative. Therefore, this intervention aligns with the client's wish to decline resuscitation. Option A is not directly related to addressing the client's immediate breathing difficulty. Option C does not acknowledge the client's living will decision. Option D involves a more invasive procedure that may go against the client's wishes to decline resuscitation.

Correct Answer: C

Rationale: When a client requires parenteral nutrition (PN) with a high dextrose concentration, such as 20%, it typically has a high osmolarity. High osmolarity solutions should be infused through a central venous line to prevent peripheral vein irritation and potential complications. Therefore, preparing the client for a central venous line is essential for the safe administration of PN with high dextrose. Monitoring blood glucose levels daily is important but not directly related to the need for a central venous line. Changing the PN infusion bag every 24 hours helps prevent bacterial contamination, but it is not the most critical action in this scenario. Administering the PN and fat emulsion together or separately is a matter of compatibility and administration guidelines, but it is not the key concern in this situation.

Correct Answer: D

Rationale: The correct answer is D: Beneficence. Beneficence involves actions intended to benefit the client, such as providing pain relief. In this scenario, the nurse is demonstrating beneficence by offering pain medication to alleviate the client's discomfort and promote their well-being. Fidelity (A) relates to being faithful to agreements and commitments, autonomy (B) refers to respecting a client's right to make decisions about their care, and justice (C) involves fairness and equal treatment. While these ethical principles are important in healthcare, the situation described primarily exemplifies the principle of beneficence.

Correct Answer: D

Rationale: The correct answer is D, Speech-language pathologist. Speech-language pathologists specialize in assessing and treating dysphagia, which is a common issue following a cerebrovascular accident. They are trained to evaluate swallowing function and provide appropriate interventions to help clients improve their ability to swallow safely. Choice A, Social worker, is incorrect as their role does not typically involve addressing dysphagia specifically. Choice B, Certified nursing assistant, is not the appropriate professional to address dysphagia concerns as they do not have the training or scope of practice for this specialized area. Choice C, Occupational therapist, focuses more on activities of daily living and functional abilities rather than the specialized treatment of dysphagia.

Correct Answer: B

Rationale: The correct answer is B. Washing and rinsing the lens storage case daily is essential to prevent contamination and infections. Choice A is incorrect as tap water should not be used to clean soft lenses due to the risk of introducing harmful microorganisms. Choice C is incorrect as the storage solution should not be reused for longer than recommended to maintain its effectiveness and prevent eye infections. Choice D is incorrect because lenses should be stored in a clean, disinfected case, not just in a cool, dry place, to avoid contamination.
