Chapter 14 : Antiepileptic Drugs Questions
Question 1 of 5
The nurse is monitoring a patient who has been taking carbamazepine for 2 months. Which effects would indicate that autoinduction has started to occur?
Correct Answer: B
Rationale: With carbamazepine, autoinduction occurs and leads to lower than expected drug concentrations.
Therefore, the dosage may have to be adjusted with time. The other options are incorrect.
Question 2 of 5
The nurse is giving an intravenous dose of phenytoin. Which action is correct when administering this drug?
Correct Answer: B
Rationale: Intravenous phenytoin is given only with normal saline solution to prevent precipitation formation caused by incompatibilities. The IV push dose must be given slowly (not exceeding 50 mg/min in adults), and the patient must be monitored for bradycardia and decreased blood pressure.
Question 3 of 5
The U.S. Food and Drug Administration has issued a warning for users of antiepileptic drugs. Based on this report, the nurse will monitor for which potential problems with this class of drugs?
Correct Answer: A
Rationale: The U.S. Food and Drug Administration (FD
A) has required black box warnings on all antiepileptic drugs regarding the risk of suicidal thoughts and behaviors. Patients being treated with antiepileptic drugs for any indication need to be monitored for the emergence or worsening of depression, suicidal thoughts or behavior, or any unusual changes in mood or behavior. The other options are incorrect.
Question 4 of 5
A patient is experiencing status epilepticus. The nurse prepares to give which drug of choice for the treatment of this condition?
Correct Answer: A
Rationale: Diazepam and lorazepam are considered by many to be the drugs of choice for status epilepticus. Other drugs that are used are listed in Table 14-3 and do not include the drugs listed in the other options.
Question 5 of 5
Phenytoin has a narrow therapeutic index. The nurse recognizes that this characteristic indicates which of these?
Correct Answer: A
Rationale: Having a narrow therapeutic index means that there is a small difference between safe and toxic drug levels. These drugs require monitoring of therapeutic plasma levels. The other options are incorrect.
