Correct Answer: A

Rationale: Rationale: A: Correct. Anxiety is characterized by apprehension, agitation, autonomic arousal, and fearful withdrawal, which are distinct from pain. B: Incorrect. Critically ill patients can experience both anxiety and pain, as pain is not exclusive to them. C: Incorrect. While pain and anxiety can be interrelated, they can be differentiated based on their unique physiological and behavioral manifestations. D: Incorrect. Pain is a subjective experience, but it is not solely defined by the individual; objective assessments are also important.

Correct Answer: B

Rationale: The correct answer is B because effective communication ensures that the patient's wishes and values are understood and respected, leading to informed decision-making. It also promotes shared decision-making among the patient, family, and healthcare team, enhancing the quality of care. Choices A, C, and D are incorrect because while they are important aspects of end-of-life care, they do not address the core element of communication in facilitating meaningful and informed decisions.

Correct Answer: D

Rationale: The correct answer is D because the patient is exhibiting Cheyne-Stokes breathing pattern characterized by periods of apnea followed by deep and rapid breathing. The nurse should document this pattern accurately. Option A is incorrect as suctioning is not indicated. Option B may worsen the respiratory pattern. Option C is not specifically related to addressing the breathing pattern.

Correct Answer: B

Rationale: The correct answer is B: Apply pressure to the insertion site for 5 minutes. This is the priority nursing action because it helps prevent bleeding and hematoma formation after removing the arterial line. Applying pressure for 5 minutes allows for adequate hemostasis. A: Applying an air occlusion dressing to the insertion site is not the priority action. It does not address the immediate need to control bleeding. C: Elevating the affected limb on pillows for 24 hours is not necessary and does not address the immediate need for hemostasis. D: Keeping the patient's wrist in a neutral position is not the priority action when discontinuing an arterial line. It does not address the need for hemostasis and preventing bleeding.

Correct Answer: D

Rationale: The correct answer is D because monitoring the surgical incision for signs of infection is essential post-VAD implantation to prevent complications. This step is crucial in early identification and treatment of any potential infection, which can lead to serious outcomes. A) Giving immunosuppressive medications is not typically required for VAD implantation, as the primary goal is to support cardiac function rather than prevent rejection. B) Preparing the patient for a permanent VAD is premature, as the goal is often to bridge to transplantation or recovery, not permanent VAD placement. C) Teaching the patient the reason for complete bed rest is not necessary for VAD implantation, as patients are typically encouraged to gradually increase activity levels under guidance.
