The nurse should prepare to administer
a. Digibind.
b. oxygen.
c. naloxone (Narcan).
d. vitamin K (Phytonadione).
ANS: A
All signs and symptoms (low heart rate, seeing halos around lights, dysrhythmias) point to digoxin toxicity. The ability of digoxin to cause dysrhythmias in patients with heart disease is greatly increased. The nurse should suspect digoxin toxicity and administer Digibind.
Oxygen may be indicated, but it will not correct the dysrhythmias or reverse the toxicity.
Naloxone is indicated for opiate overdose, not digoxin toxicity.
Vitamin K is indicated for excessive bleeding, specifically for warfarin toxicity.
