Correct Answer: C

Rationale: The correct answer is C: Hypoglycemia. At 4:30 p.m., after taking the morning insulin, the client's blood sugar may have dropped too low, leading to symptoms like headache, sweating, tremor, pallor, and nervousness. Regular insulin and NPH insulin peak at different times, causing a potential mismatch in insulin action, leading to hypoglycemia. Hyperglycemia (A) would present with different symptoms like increased thirst and urination. Hyperuricemia (B) is an excess of uric acid in the blood and does not typically present with these symptoms. Hypochondria (D) is a psychological condition and not related to the client's physical symptoms.

Correct Answer: A

Rationale: The correct answer is A because it encourages the novice nurse to independently observe the situation with a peer, validate the data, and discuss afterward. This approach promotes reflection, peer learning, and validation of collected data, which are essential for learning and growth. It allows the nurse to self-assess and correct errors through discussion and feedback. Choice B is incorrect as it does not address the need for validation and peer feedback. Choice C is incorrect as repeating the same mistake without guidance does not promote learning. Choice D is incorrect as meeting with the nurse manager may not provide the same level of peer learning and validation as observing with a peer.

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: D

Rationale: The correct answer is D, assess vital signs, as it is crucial to monitor the client's hemodynamic stability and response to treatment during the critical initial 24 hours of Addisonian crisis. Vital signs such as blood pressure, heart rate, and respiratory rate provide valuable information about the client's condition and response to therapy. Weighing the client (choice A) and testing urine for ketones (choice C) may be important but not as immediately critical as monitoring vital signs. Administering oral hydrocortisone (choice B) is essential for treatment but does not require frequent administration within the first 24 hours.

Correct Answer: A

Rationale: The correct answer is A: 2 and 5. Diminished breath sounds indicate possible atelectasis or pneumonia post-operatively, making coughing and deep breathing (2) and ambulation (5) crucial to prevent complications. Decreasing fluid intake (iv) can lead to dehydration, worsening the situation. Administering antibiotics (i) without further assessment may not be necessary at this point. Acetaminophen (iii) can help with fever but does not address the underlying respiratory issue.
