Correct Answer: D

Rationale: The correct answer is to stop the transfusion. When a nurse suspects an adverse reaction to a blood transfusion, the priority is to stop the infusion immediately to prevent further harm to the client. Maintaining IV access and obtaining vital signs can be important steps but should come after stopping the transfusion to ensure the client's safety. Contacting the provider is necessary but not the first action to take in this situation. Therefore, the nurse should prioritize stopping the transfusion to address the potential adverse reaction.

Correct Answer: C

Rationale: The correct information that the nurse should include in the teaching about a CPAP device is that it delivers a preset amount of airway pressure throughout the breathing cycle. This consistent positive airway pressure helps keep the airway open during both inspiration and expiration. Choice A is incorrect as CPAP does not deliver pressure only at the beginning of each breath. Choice B is incorrect because CPAP provides a constant level of pressure without continuous adjustments throughout the cycle. Choice D is incorrect as CPAP does not provide positive pressure at the end of each breath; instead, it maintains a continuous positive pressure.

Correct Answer: B

Rationale: A positive Kernig's sign is identified when a client is unable to extend their leg completely without pain after hip flexion. This finding indicates meningeal irritation. Choices A, C, and D do not describe Kernig's sign. Choice A describes a normal plantar reflex, choice C refers to coordination issues, and choice D describes neck pain and stiffness, which are not specific to Kernig's sign.

Correct Answer: A

Rationale: Choice A is the correct answer. This statement demonstrates effective coping as the client is showing acceptance of their disability and planning for the future with realistic goals. Choice B reflects denial of the permanent disability by stating that they will only be in a wheelchair temporarily. Choice C shows distress and a lack of acceptance by questioning why the injury happened and why they are not improving. Choice D indicates feelings of hopelessness and being a burden, which are not signs of effective coping.

Correct Answer: A

Rationale: The correct answer is A. The nurse should report these vital signs to the provider immediately as they indicate increased temperature, tachycardia, and tachypnea, which are signs of possible infection or systemic inflammatory response. This could exacerbate the client's unstable angina and needs prompt evaluation. Choices B, C, and D are not as urgent as the vital signs in option A and do not directly indicate a worsening condition in the context of unstable angina.
