DNH 235 Nitrous Oxide Questions and Answers 100% Correct
Advantages of nitrous oxide/oxygen sedation anesthesia correct answer Mild analgesic and sedative
Increase relaxation and cooperative during treatment
Reduces gag reflex
Very safe - minimal side effects
Medically compromised patients
Prevents emergencies from anxiety and stress
Readily absorbed and excreted from the body, rapid onset and recovery
Appointments less stressful
Anesthetic and analgesic properties correct answer - produces analgesia
- 30 to 40% N2O optimum for most patients
- Reduces intensity of pain, but does not block it
- Combined with local anesthetic when patient significant discomfort
ASA classifications correct answer ASA I—Normal/healthy.
ASA II—Mild to moderate systemic disease.
ASA III—Severe systemic disease that limits activity but is not incapacitating.
ASA IV—Severe systemic disease that threatens life.
ASA V—Patient will die within 24 hours.
**Patients with chronic obstructive pulmonary disease (COPD) ASA IV should not be given N2O/O2
sedation.
