 A patient has been taking an antiepileptic drug for several years for treatment of partial seizures. His wife calls because he has run out of his medications. She asks if he can go without it for a week until she has a change to get to the drugstore. What is the nurse's best response? (0.5 pts)

a.      "If he is taking another antiepileptic drug, he can go without the medication for a week."

b.     "Stopping this medication abruptly may cause withdrawal seizure. A refill is needed right away."

c.      "Since he has been treated for several years the medication he should be fine without this medication for a few days."

d.     "He can take an extra pill of his other antiepileptic medication until this one is filled at the pharmacy."

 

11.  Explain why the answer you chose in question 9 is the best response to this patient's wife? (1.5 pt)

 

12.  You are on the medical-surgical floor today. Your patient is a 30-year-old male who has known seizure disorder. You have an order to give this patient Oral (PO) Phenytoin 125mg three times a day (Dilantin, an antiseizure medication). You check the labs and note that his liver enzymes are going up dramatically. You suspect that the Phenytoin is causing the elevation in liver enzymes. Please explain why would this drug be contributing to an increase in this patients liver enzymes? This goes back to pharmacokinetics. (1 pt)

 

13.  There are 4 mechanism of action for anti-elliptic (antiseizure) drugs (found in your book and lecture notes). Please list the 4 mechanisms of action here. (You only need to list them). (1 point; .025 each)

 

14.  Explain the mechanism of action of Phenytoin (found in powepoint and your book). In other words, how does phenytoin reduce or prevent seizure activity?
