Correct Answer: A

Rationale: The correct answer is A because decorticate posturing is characterized by flexion of both upper and lower extremities. This occurs due to damage to the cerebral hemispheres, resulting in abnormal muscle contractions. Choice B describes decerebrate posturing, which is associated with extension of elbows and knees. Choice C is incorrect as it describes abnormal posturing seen in other conditions. Choice D is also incorrect as it describes a different type of abnormal posturing.

Correct Answer: C

Rationale: Step 1: The nurse should explain that bladder irrigation is necessary to prevent blood clots from occluding the catheter after a TURP procedure. Step 2: Without irrigation, blood clots could block the catheter, leading to urinary retention and potential complications. Step 3: This explanation addresses the patient's concern about increased pain and highlights the importance of the irrigation in maintaining proper urine flow. Step 4: Choice A is incorrect because the primary purpose of irrigation is not to stop bleeding but to prevent clot formation. Choice B is incorrect because the irrigation is not for administering antibiotics. Choice D is incorrect as it does not address the issue of clot formation.

Correct Answer: A

Rationale: The correct answer is A: Maintain strict records of intake and output. This is the best way to assess fluid balance in a burn patient because it provides quantitative data on fluid intake and output, helping to monitor for fluid imbalance. Monitoring skin turgor (B) is unreliable in burn patients due to skin damage. Weighing the client daily (C) may not accurately reflect fluid balance changes. Checking for edema (D) is not specific to assessing fluid balance in burn patients. Maintaining intake and output records allows for precise monitoring and early detection of fluid shifts, making it the most appropriate choice.

Correct Answer: D

Rationale: The correct answer is D: Autoimmune reaction. Guillain-Barre Syndrome is an autoimmune disorder where the immune system mistakenly attacks the peripheral nerves, leading to muscle weakness and paralysis. This is supported by the patient's presentation of weakness in the legs. Bacterial infection (A) can trigger Guillain-Barre Syndrome, but it is not the root cause. High-fat diet (B) and heredity (C) are not associated with the development of this syndrome. In summary, autoimmune reaction is the primary mechanism underlying Guillain-Barre Syndrome, resulting in the patient's muscle weakness and inability to walk.
