Question 15

This can be used if the pt is allergic to LA.

Answer 15

General anesthesia

Question 16

Contraindication to office sedation.

Answer 16

Obstructive sleep apnea.

Basically any type of compromised airway.

Question 17

This facilitates complete control of the airway, breathing, and circulation.

Answer 17

GA

Question 18

Can be administered without moving the patient from a supine position.

Answer 18

GA

Question 19

Dangerous reaction to GA

Answer 19

Malignant hyperthermia

Question 20

Changes in cognition and psychomotor performance are altered for how many after GA?

Answer 20

24-36 hours.

Question 21

During GA, this INCREASES bc there’s a decreased tidal volume.

Answer 21

Respiratory Rate

Question 22

Respiratory effects of GA.

Answer 22

• Increased arterial CO2
• Depressed response to increases in arterial CO2.
• Depressed response to decreases in arterial O2.
• Decreased tidal volume.
• Increased respiratory rate.

Question 23

A decrease in this type of resistance occurs with GA.

Answer 23

airway

Question 24

You produce apnea with greater depths of anesthesia.

Answer 24

True

Question 25

You reduce function of this with GA.

Answer 25

tracheal ciliary function

Question 26

This cardiovascular thing increases in GA.

Answer 26

Heart rate, but net decreased arterial BP.

Question 27

CV effects of GA.

Answer 27

- Increased HR - Decreased arterial BP - Decreased sympathetic tone (decreased peripheral resistance). - Decreased CO. - Preservation of coronary blood flow.

Question 28

Types of Catecholamines.

Answer 28

Epi NE Dopamine

Question 29

Volatile General Anesthetic that sensitizes the myocardium to catecholamines.

Answer 29

Halothane

Question 30

This occurs in up to 60% of patients on general anesthesia.

Answer 30

Cardiac dysrrhythmias

Question 31

GA increases blood flow to these organs.

Answer 31

Brain Muscle Skin

Question 32

Decreased levels of this when using GA.

Answer 32

Insulin | Testosterone

Question 33

This anesthetic has little to no effect on Insulin levels.

Answer 33

Sevoflurane

Question 34

Potential toxicities with GA.

Answer 34

Renal toxicitiy

Question 35

Anesthetic that has the greatest risk of hepatic necrosis.

Answer 35

Halothane

Question 36

Most common hepatotoxic drug in the US.

Answer 36

Alcohol

Question 37

An inherited disorder of muscle metabolism where Calcium remains bound to myosin, causing muscle rigidity. Energy is generated as heat and these patients' temperatures skyrocket.

Answer 37

Malignant Hyperthermia

Question 38

This is released when inhalational drugs are metabolized, causing damage to the kidneys.

Answer 38

Fluorine

Question 39

All halogenated hydrocarbons used for anesthesia have these attached.

Answer 39

Fluorine or Bromine

Question 40

Determines if a patient is breathing properly.

Answer 40

Capnography.

Question 41

Rapid induction bc it has low blood and tissue solubility.

Answer 41

Desflurane

Question 42

Agent that has less depression of diaphragmatic function than other agents.

Answer 42

Sevoflurane

Question 43

What is emergence.

Answer 43

Waking the patient up from general anesthesia.

Question 44

Muscle relaxants prevent these from shutting.

Answer 44

Vocal cords

Question 45

Induction of GA combines these two drugs.

Answer 45

Sedative + Muscle relaxant.

Question 46

IV induction involves this.

Answer 46

Pre-oxygenation Done before intubation

Question 47

You should not be sedating your patient if you can't do this.

Answer 47

Intubate them.

Question 48

These should be at the same level when intubating.

Answer 48

Ear and Sternal notch

Question 49
