Question 1 of 5
A nurse is preparing to administer phenytoin 50 mg IV bolus to a client who has a seizure disorder. The medication is supplied as a 50 mg/mL vial. Which of the following actions should the nurse take?
Correct Answer: D
Rationale: The correct answer is D: Administer the medication over 1 min. Administering phenytoin rapidly can lead to adverse effects such as hypotension or cardiac arrhythmias. By administering it over 1 min, the nurse ensures a controlled rate of infusion, reducing the risk of these complications.
A: Diluting with sterile water is not recommended for IV phenytoin as it can lead to precipitation and reduce the drug's efficacy.
B: Following with sterile water is unnecessary and not indicated.
C: Slowing the injection if crystallization occurs can still lead to adverse effects; it's best to prevent crystallization by proper administration.
In summary, administering phenytoin IV over 1 min is the safest and most effective method to prevent adverse reactions.
