A patient, without prior medication, breathes a gas mixture consisting of 50 percent nitrous oxide and 50 percent oxygen by volume. Which of the following effects would be expected_____________?
Correct answer: A. Analgesia
- A. Analgesia
- B. Excitation
- C. Surgical anesthesia
- D. Respiratory arrest
Explanation
A 50% nitrous oxide and oxygen mixture produces analgesia but is not strong enough to produce surgical anaesthesia in an unmedicated patient. Excitation or respiratory arrest would not be the expected primary effect at this concentration.
