Correct Answer: B

Rationale: The correct answer is B: Redness of the upper part of the feet. During lymphangiography, a contrast dye is injected into the lymphatic vessels. This may cause temporary redness in the upper part of the feet due to the dye spreading throughout the lymphatic system. Purplish stools (A), bluish urine (C), and coldness of the soles (D) are not expected side effects of lymphangiography and do not have a direct correlation with the procedure.

Correct Answer: A

Rationale: The correct answer is A: Type I (immediate, anaphylactic) hypersensitivity reaction. In this scenario, the client experiences symptoms shortly after the transfusion starts, such as chest pain, nausea, itching, urticaria, tachycardia, and hypotension, which are indicative of an immediate hypersensitivity reaction. Type I reactions involve the release of histamine and other inflammatory mediators from mast cells and basophils, leading to the symptoms described. The nurse's prompt action of stopping the transfusion and notifying the physician aligns with managing this type of reaction. Incorrect choices: B: Type II (cytolytic, cytotoxic) hypersensitivity reaction - This type of reaction involves antibodies targeting specific cells, leading to their destruction. The symptoms described in the scenario are not consistent with this type of reaction. C: Type III (immune complex) hypersensitivity reaction - This type of reaction involves the formation of immune complexes that deposit in tissues, causing

Correct Answer: C

Rationale: The correct answer is C because pronation-supination of the hand and forearm is a characteristic movement in Parkinson's disease called "pill-rolling tremor." This movement interferes with normal hand activities due to involuntary shaking. A is incorrect because exaggerated muscle flaccidity does not lead to frequent falls in Parkinson's disease. B is incorrect as hyperextension of the back and neck is not a characteristic movement of Parkinson's disease. D is incorrect as it combines all options, which is not accurate.

Correct Answer: C

Rationale: The correct answer is C: Call the physician. In this scenario, the sudden severe headache and nasal congestion along with flushed skin and goosebumps suggest autonomic dysreflexia, a medical emergency in spinal cord injury at or above T6. The nurse should immediately call the physician to address this potentially life-threatening situation. Raising the client's head (A) may worsen the condition, placing the client on a firm mattress (B) is not a priority, and administering an analgesic (D) without addressing the underlying cause could lead to further complications. The priority is to identify and address the cause of autonomic dysreflexia promptly.

Correct Answer: C

Rationale: The correct answer is C because data validation involves comparing data with other sources to ensure accuracy. This process checks for errors, inconsistencies, and completeness in the data. By comparing data with other sources, nurses can verify the reliability and correctness of the information. Choice A is incorrect because data validation typically occurs after data collection and before data interpretation. Choice B is incorrect because validation is about ensuring data accuracy, not about professional standards. Choice D is incorrect because data interpretation focuses on analyzing and making sense of the data, not on professional standards or validation processes.
