NEURO FINAL EXAM URDEN NEURO FINAL EXAM URDEN NEURO FINAL EXAM URDEN 1. Which of the following arterial blood gas values would indicate a need for oxygen therapy? a. PaO2 of 80 mm Hg c. HCO3- of 24 mEq b. PaCO2 of 35 mm Hg d. SaO2 of 87% ANS: D The amount of oxygen administered depends on the pathophysiologic mechanisms affecting the patient's oxygenation status. In most cases, the amount required should provide an arterial partial pressure of oxygen (PaO2) of greater than 60 mm...

A patient is admitted to the emergency department with severe recurrent convulsive seizures. What drug would the nurse expect to be ordered for use in emergency control of status epilepticus? A) Phenytoin (Dilantin) B) Diazepam (Valium) C) Phenobarbital (Luminal) D) Ethosuximide (Zarontin) Ans: C Feedback: Phenobarbital is used for emergency control of status epilepticus. This barbiturate inhibits impulse conduction in the ascending reticular activating system (RAS), depresses the cereb...
