As you prepare to administer the phenytoin, you see that A.A. has D5W infusing at 75 mL/hr
Why does this concern you and what are your options?
What will be an ideal response?
Phenytoin (Dilantin) should be given only with normal saline IV fluids because it will precipitate in
the presence of D5W. You have two options:
• Keep the current IV infusion of D5W. Start a second line and infuse the phenytoin (Dilantin)
through that site.
• Change the current IV solution to 0.9% normal saline and then administer the phenytoin (Dilantin).
Flush the line and resume the D5W after the phenytoin is complete.
