The nurse is caring for a patient in the operating suite. Which outcome will be most appropriate for this patient at the end of the intraoperative phase?

Correct Answer: A

Rationale: The correct answer is A because being free of burns at the grounding pad is crucial for patient safety during surgery. If burns occur, it can lead to serious complications. Choices B, C, and D are important outcomes as well, but they are not as critical as preventing burns during the intraoperative phase. Nausea, vomiting, infection, and pain can be managed postoperatively, but preventing burns is a priority during the surgery itself.

Correct Answer: D

Rationale: The correct answer is D because the patient with diabetic ketoacidosis typically presents with dehydration, which is indicated by dry skin and mucous membranes. The increased thirst and frequent urination reported by family members are classic symptoms of uncontrolled diabetes leading to DKA. Hypotension and shallow rapid respirations are also common in DKA due to the metabolic acidosis. Choices A, B, and C are incorrect because they do not align with the typical presentation of diabetic ketoacidosis. Choice A describes a patient with hypoglycemia. Choice B describes a patient with septic shock. Choice C describes a patient with hypothermia. Therefore, based on the symptoms described and the patient's diabetic history, choice D is the most likely indication of diabetic ketoacidosis.

Correct Answer: A

Rationale: The correct answer is A: ST segment. The ST segment represents the early part of ventricular repolarization as it signifies the period between ventricular depolarization (end of QRS complex) and complete repolarization (T wave). This segment is important in assessing myocardial ischemia or injury. The other choices are incorrect because: B: PR interval signifies atrial depolarization. C: QT interval represents the entire ventricular depolarization and repolarization. D: QRS complex represents ventricular depolarization.

Correct Answer: B

Rationale: The correct answer is B because in a severely hypothermic patient in cardiac arrest, the body's metabolism is slowed, affecting drug absorption and metabolism. Administering IV medications at longer intervals helps prevent toxicity as the body cannot process them efficiently. Choice A is incorrect because warm fluid and active rewarming are not sufficient to address medication metabolism issues. Choice C is incorrect as toxicity is a concern due to impaired drug clearance. Choice D is incorrect as higher doses can lead to toxicity in a hypothermic patient.

Correct Answer: C

Rationale: Rationale: The correct answer is C: Subdural hematoma. Subdural hematoma is a collection of blood between the dura mater and arachnoid mater of the brain, often caused by head trauma. Symptoms include headache, confusion, and visual disturbances, which align with the patient's presentation. Subdural hematomas can develop gradually after a head injury, leading to delayed symptoms. Other choices: A: Coup-contra-coup injury - This injury involves the brain hitting the skull on both sides due to acceleration-deceleration forces, but it typically presents with focal neurological deficits rather than the diffuse symptoms described. B: Diffuse axonal injury - This injury involves widespread damage to nerve fibers in the brain, leading to coma or altered consciousness rather than confusion and visual disturbances. D: Epidural hematoma - This injury is a collection of blood between the skull and dura mater, typically causing rapid deterioration in mental status and focal neurological deficits, not confusion
