-Physical Status

General Anesthesia - CORRECT ANSWER a reversible state of unconsciousness, consisting of amnesia, analgesia, and muscle relaxation
Regional Anesthesia - CORRECT ANSWER a reversible loss of sensation, which is achieved by injecting a local anesthetic to block the nerve fibers from transmitting impulses.
Local Anesthesia - CORRECT ANSWER functions like regional anesthesia but usually applies to a smaller area or a single body part such as a finger or a toe.
Monitored Anesthesia Care (MAC) - CORRECT ANSWER consists of intravenous medications and concurrent local infiltration of tissue at the surgical site
What are the Four STAGES of Anesthesia? - CORRECT ANSWER • Stage I: Initial Administration - The first stage is the actual administering of the anesthetic drugs. There are only a few seconds in between the initial administering of the drug and unconsciousness.
• Stage II: Excitement - In Stage II the patient is now unconscious. Also known as "excitement", is the time from loss of consciousness to the loss of eyelid reflex. Involuntary movements may occur at this time.
• Stage III: Intrasurgery - This is the time of surgical anesthesia. The patient has rapid eye movement and breathing may be labored until the muscles completely relax. It is time to start the surgery.
• Stage IV: Possibility of respiratory failure - During this last stage of anesthesia, the patient might need help. If too much anesthesia has been given, this stage is characterized by respiratory failure, leading to circulatory failure. Without breathing apparatus and heart support, the patient can die.
What are the three PHASES of anesthesia? - CORRECT ANSWER • Induction - This phase begins with the administration of anesthesia and lasts until the surgical incision is made.
• Maintenance - This phase begins with the surgical incision and lasts until near completion of the procedure (Stage 3).
• Emergence - This phase starts as the patient begins to awaken and ends upon exiting the operating room
IV regional anesthesia (Beir Block) is most often used for: - CORRECT ANSWER Upper extremity nerve blockade
A common side effect to monitor after spinal anesthesia is: - CORRECT ANSWER hypotension due to vasodilation
What is the most consistent physiological indication of Malignant Hyperthermia? - CORRECT ANSWER Increased end tidal CO2
What drug is given for Malignant Hyperthermia? - CORRECT ANSWER Dantrolene
*Also, stop triggering agents, give 100% oxygen, cool pt
During Monitored Anesthesia Care (MAC), the Pt is monitored for what 3 risks? - CORRECT ANSWER • Extravasation of intravenous medication
• A reduction of arterial oxygen saturation
• Breathing difficulty
During a peripheral nerve block, why must there be continuous nerve stimulation in the area to be anesthetized? - CORRECT ANSWER To ensure proper needle placement
Special considerations for Pt undergoing endoscopic or minimally invasive surgery include: (4 answers) - CORRECT ANSWER -Previous incisions (may alter the trocar insertion technique)
-History of DVT
-Consent to include possibility of open procedure
-Voiding prior to surgery (empty bladder helps to avoid puncture during trocar placement & decrease need for catheterization)
Fluid management in Minimally Invasive Surgery involves risk of: (2 answers) - CORRECT ANSWER -Hypothermia
-Fluid overload [Show Less]
