The nurse admits a patient to the emergency department who complains of dizziness, light-headedness, and a pulsating headache. Further assessment reveals a blood pressure of 82/60 and palpitations
The patient's friends state that "he was experimenting with poppers." The nurse should plan to administer which of the following medications? a. Diazepam (Valium)
b. Naloxone (Narcan)
c. Haloperidol (Haldol)
d. Methylene blue and supplemental oxygen
D
These findings are consistent with volatile nitrate overdose, as evidenced by the venous dilation. The primary toxicity is methemoglobinemia, which can be treated with methylene blue and sup-plemental oxygen.
Diazepam would not be used for patients experiencing volatile nitrate overdose, but it may be used in patients who have overdosed on hallucinogens.
Naloxone would be used to treat an opioid overdose.
Haloperidol would be used in patients who have overdosed on amphetamines.
