Drugs for Peripheral Nervous System Questions
Question 1 of 5
Which of the following drugs most likely caused the patient's syndrome?
Correct Answer: A
Rationale: The correct answer is A: Amyl nitrite. Amyl nitrite is known to cause methemoglobinemia, which can present as the syndrome described in the patient. Nitrous oxide, propane, and helium do not typically cause methemoglobinemia. Amyl nitrite acts as a vasodilator and can lead to the formation of methemoglobin, reducing the oxygen-carrying capacity of blood. Methemoglobinemia can manifest as cyanosis, headache, dizziness, fatigue, and shortness of breath. Nitrous oxide is an anesthetic gas that does not cause methemoglobinemia. Propane and helium are gases used for various purposes but are not associated with methemoglobinemia. Therefore, based on the patient's symptoms and the mechanism of action of the drugs listed, amyl nitrite is the most likely cause of the syndrome.
