Correct Answer: C

Rationale: The correct answer is C: Joint abnormalities. In rheumatoid arthritis, joint abnormalities such as swelling, warmth, and tenderness are the hallmark manifestations. Assessing joint abnormalities first is crucial as they are the primary clinical signs of the disease. Muscle weakness (A) is a common symptom but typically occurs later due to joint inflammation and disuse. Painful subcutaneous nodules (B) are present in some cases but are not as common or prominent as joint abnormalities. Gait disturbances (D) may occur as a result of joint damage, but they are secondary to the primary manifestation of joint abnormalities. By prioritizing the assessment of joint abnormalities, the nurse can promptly identify and address the most prevalent disease manifestations in rheumatoid arthritis.

Correct Answer: B

Rationale: The correct answer is B: The client wears a watch and wedding band. This is because metal objects such as watches and jewelry can be hazardous during an MRI scan due to the strong magnetic field, leading to potential movement or heating of the metal objects, causing harm to the client. A: The client lies still - This is important for obtaining clear images during an MRI scan and does not pose a threat to the client. C: The client asks questions - Asking questions during an MRI scan does not pose a direct threat to the client's safety. D: The client hears thumping sounds - Thumping sounds are a normal part of the MRI scan and do not pose a threat to the client's safety.

Correct Answer: C

Rationale: The correct answer is C: “Nurses use evaluation to determine the effectiveness of nursing care.” Evaluation in nursing is essential to assess the outcomes of nursing interventions and determine the effectiveness of the care provided. It helps in identifying areas for improvement, making informed decisions, and ensuring quality patient care. Choice A is incorrect because evaluation is not solely about checking completion of tasks but rather assessing the impact of those interventions on patient outcomes. Choice B is incorrect as evaluation is not related to staffing decisions but focuses on assessing the quality of care delivery. Choice D is incorrect as evaluation is not about eliminating paperwork but rather about improving care outcomes.

Correct Answer: A

Rationale: The correct answer is A: Removal of the transplanted kidney. Hyperacute rejection is a severe and immediate immune response to the transplanted organ. In this case, the transplanted kidney must be removed promptly to prevent further complications, as it is irreversibly damaged. High-dose IV cyclosporine (B) is used for immunosuppression but is not effective in treating hyperacute rejection. Bone marrow transplant (C) is not indicated for kidney rejection. Intra-abdominal instillation of methylprednisolone sodium succinate (D) is used for acute rejection, not hyperacute rejection.

Correct Answer: A

Rationale: The correct answer is A: Norepinephrine. Norepinephrine is the primary neurotransmitter that mediates the sympathetic response. It is released by sympathetic nerve endings and acts on adrenergic receptors in various target organs to initiate the "fight or flight" response. Prostaglandin, acetylcholine, and serotonin do not directly mediate the sympathetic response and are involved in different physiological processes.
