FINAL EXAM REVIEW: AORN PERI-OP
101, 2025/2026 WITH
CORRECT/ACCURATE ANSWERS
What are examples of volatile liquids in the OR?
1. Skin antiseptic agents
2. Anesthetic Gases
3. Specimen Fixatives
4. Lubricants.
What is a bier block?
IV Regional Anesthesia. Used for procedures on the hand, wrist or
forearm.
How is a bier block performed?
1. IV placement in the extremity which will have the surgery.
2. Placement of double tourniquet
3. Limb exsanguination
4. Inflation of the proximal cuff
5. Local anesthetic is injected
6. If cuff discomfort occurs, the distal cuff is inflated then the
proximal cuff is deflated
7. Anesthetic lasts until both cuffs are deflated.
Role of the peri-operative RN for Bier Blocks
1. Maintain the tourniquet times.
2. Ensure tourniquet is deflated slowly to prevent a bolus of local
anesthetic from entering the circulation.

, 1. Sudden, unexplained tachycardia and
2. Rise in end-tidal CO2 production
3. Hypercarbia
4. Dangerously high body temperature
5. Hyperkalemia
6. Severe muscle spasms with localized muscle rigidity.
7. Ventricular dysrhythmias
Risk factors for hypothermia
1. Hypothyroidism
2. Hypoglycemia
3. Burns
4. Trauma
5. Congestive Heart Failure (CHF)
6. Cardiac Vessel Disease
7. Hypotension
8. Previous Cardiac Surgery
9. Previous Organ Transplant
10. Elderly
11. Infants and Children
12. Females
13. Patients with lower than normal body weight
What are 5 complications that can occur related to anesthesia
administration?
1. Difficult Airway
2. Laryngospasm
3. Cardiac Problems
a. Hypertension
b. Hypotension
c. Bradycardia
d. Tachycardia
