Correct Answer: B

Rationale: When caring for clients with dementia, addressing restlessness and agitation is a priority as it can lead to distress, safety risks, and potential harm to the client or others. Restlessness and agitation are common behavioral symptoms of dementia and can indicate unmet needs, discomfort, or confusion. Managing these symptoms promptly can help improve the client's quality of life and prevent complications such as falls, injuries, or escalation of challenging behaviors. While other issues like mild confusion, incontinence, and wandering are also important to address, managing restlessness and agitation takes precedence due to its immediate impact on the client's well-being and safety.

Correct Answer: B

Rationale: The correct answer is B: Ensure the blood type is compatible with the client. This is the most crucial step in preparing for a blood transfusion to prevent severe transfusion reactions. Checking the client for a fever (Choice A) is important but not the most critical step. Administering blood via IV push (Choice C) is incorrect as blood transfusions are usually administered as a slow drip. Warming the blood to body temperature (Choice D) is not a standard practice and can lead to hemolysis, making it an incorrect choice.

Correct Answer: C

Rationale: When signs of phlebitis are observed in a client receiving IV fluids, the appropriate action is to apply a warm compress. This helps to reduce discomfort and swelling at the site of the IV insertion. Applying a cold compress may not be as effective in this case and could potentially worsen the condition. While notifying the physician is important, providing immediate comfort to the client through a warm compress is the initial recommended intervention. Administering anti-inflammatory medication should only be done under the direction of a healthcare provider after assessment and evaluation of the client's condition.

Correct Answer: C

Rationale: The correct answer is C: Justice. Justice in healthcare ethics refers to fairness and equality in the distribution of resources and treatments. In this scenario, ensuring that all clients waiting for a kidney transplant meet the same qualifications demonstrates the ethical principle of justice by providing equal opportunities for all candidates. Choice A, fidelity, pertains to keeping promises and being faithful to agreements, which is not the primary ethical principle at play in this situation. Autonomy, choice B, relates to respecting a patient's right to make their own decisions, which is not directly applicable in the context of organ transplant qualifications. Non-maleficence, choice D, refers to the principle of doing no harm, which is important but not the primary ethical principle highlighted in this scenario.

Correct Answer: C

Rationale: The correct answer is C: 'Take up to three tablets during a single angina episode.' Nitroglycerin can be taken up to three times during an episode to relieve angina. Choice A is incorrect because the client should place the tablet under the tongue and wait for it to dissolve, not wait for 10 minutes. Choice B is incorrect because taking up to five tablets during an angina episode is excessive and not recommended. Choice D is incorrect because nitroglycerin tablets are meant to be taken sublingually, not swallowed.
