Answer : C

Given the symptoms of unilateral facial droop and slurred speech, a stroke is highly suspected. A head and neck CT scan is the most appropriate initial imaging to quickly evaluate for the presence of an ischemic or hemorrhagic stroke, which is critical for determining the appropriate treatment plan. An MRI may provide more detailed information later but is not the initial test of choice in the acute setting. Reference: = CCRN Exam Handbook, AACN Adult CCRN Certification Review Course

Answer : D

A serum potassium level of 7.2 mEq/L is critically high and can lead to life-threatening cardiac arrhythmias. The most immediate intervention is the administration of 50% dextrose followed by insulin, which helps drive potassium back into the cells, thereby rapidly lowering the serum potassium level. Hemodialysis and Kayexalate are also effective but may not act as quickly as the dextrose-insulin combination. Reference: = CCRN Exam Handbook, AACN Adult CCRN Certification Review Course

Answer : D

While it is important to support family involvement, previous disruptive behavior necessitates setting clear behavioral limits to ensure a safe and therapeutic environment for the patient. Allowing the visit with established guidelines helps balance the need for patient support with maintaining unit order. This approach also respects the patient's rest and recovery needs.

Answer : C

The patient's tachycardia and hypotension following bowel resection surgery indicate potential severe complications such as hemorrhage or septic shock, which require immediate intervention. If the on-call surgical resident does not provide new orders, the nurse must act promptly to prevent further deterioration by initiating the rapid response team (RRT). The RRT can provide critical interventions and facilitate timely transfer to a higher level of care if needed. Reference: = CCRN Exam Handbook, AACN Adult CCRN Certification Review Course

Answer : D

In hypertensive crisis, neurologic changes are often caused by increased intracranial pressure (ICP) as a result of loss of cerebral autoregulation. Autoregulation normally maintains consistent cerebral blood flow despite changes in systemic blood pressure. In hypertensive crisis, the extremely high blood pressure overwhelms these mechanisms, leading to increased cerebral blood flow, disruption of the blood-brain barrier, and cerebral edema, which subsequently increases ICP and causes neurologic changes.
