A client who is experiencing frequent seizure activity has a single peripheral intravenous (IV) catheter infusing 5% dextrose in water (D5W) continuously. The healthcare provider prescribes a stat dose of IV phenytoin. Which of the following actions should the nurse perform to safely administer this medication? (Select all that apply)

  1. Pause the primary D5W infusion and flush the IV line with 0.9% sodium chloride before the injection.Cevap
  2. B
    Administer the phenytoin via a secondary Y-site port while the continuous D5W infusion is running.
  3. C
    Inject the medication rapidly over 30 to 45 seconds to quickly achieve therapeutic serum levels.
  4. Flush the IV catheter with 0.9% sodium chloride immediately after completing the medication injection.Cevap
  5. Monitor the client's cardiac rhythm and blood pressure continuously during the medication administration.Cevap
  6. F
    Dilute the phenytoin dose in a syringe with sterile water for injection to minimize vein irritation.

Cevap

The correct actions include pausing the D5W infusion to flush with normal saline before the injection, flushing with normal saline after the injection, and continuously monitoring the client's cardiac rhythm and blood pressure.
Phenytoin is physically incompatible with any dextrose-containing solution and requires a dedicated line or thorough flushing with 0.9% sodium chloride before and after administration to prevent precipitation. Due to its potential to cause severe hypotension, bradycardia, and arrhythmias, continuous cardiovascular monitoring is mandatory during administration.

Adım Adım Çözüm

1
Analyze the client's current intravenous setup and the prescribed medication.
The client is receiving 5% dextrose in water (D5W) continuously, and the new prescription is for IV phenytoin.
Identifying the primary IV fluid is essential because phenytoin is highly incompatible with dextrose solutions and will precipitate.
2
Determine the necessary actions to prevent medication precipitation in the IV line.
The nurse must stop the D5W infusion and flush the line with 0.9% sodium chloride before and after giving the phenytoin.
Normal saline is the only compatible fluid for flushing and diluting IV phenytoin.
3
Evaluate the safe administration rate and required monitoring for IV phenytoin.
The medication must be administered slowly, and the client requires continuous cardiac and blood pressure monitoring.
Rapid infusion of phenytoin can lead to severe hypotension and life-threatening cardiac arrhythmias.
