-
Phenytoin
-
Cyclophosphamide
-

-
Magnesium
Pregunta 3
Pregunta

Respuesta
-
Potency
-
Lipophilicity
-
Ionization
-
Plasma clearance
-
E. Receptor affinity

Respuesta
-
Significant histamine release after a bolus injection
-
Vagolysis producing tachycardia
-
Hofmann elimination
-
Deacetylation in the liver
-
Production of laudanosine as the primary metabolite
Pregunta 5
Pregunta
Clinical data support that when the TOFR exceeds [blank_start]__[blank_end],
anesthesia providers have trouble assessing the presence
of fade
Respuesta
-
0.4
-
0.2
-
0.7
-
0.9
Pregunta 6
Pregunta
TOF count of 3 would equate to a twitch suppression of [blank_start]__[blank_end]%
Image:
Tofc (binary/octet-stream)
Respuesta
-
55
-
75
-
85
-
90
Pregunta 7
Pregunta
Once the TOF ratio exceeds [blank_start]0.60[blank_end], fade to DBS generally cannot be detected subjectively
Image:
Dbs (binary/octet-stream)
Respuesta
-
0.60
-
0.40
-
0.70
-
0.85
Pregunta 8
Respuesta
-
During partial depolarizing block, fade is not observed in response to tetanic stimulation
-
Tetanic stimulation is not painful
-
Muscular fatigue usually develop at a stimulation frequency of 50 Hz
-
Fade is thought to be an effect of a depolarizing agent on the presynaptic nerve membrane
Pregunta 9
Respuesta
-
The number of posttetanic count twitches is inversely related to time until the first regular TOF twitch returns
-
Posttetanic count used when TOF or DBS is absent to estimate recovery time
-
Posttetanic count uses tetany followed by TOF at frequency of 1 Hz
-
The main use of posttetanic count is when profound neuromuscular block is not required
Pregunta 10
Pregunta
Correct statements about objective monitoring techniques include:
Respuesta
-
Mechanomyography (MMG) measures isotonic contraction of peripheral muscles in response to nerve stimulation
-
Acceleromyography (AMG) calculates the force of contraction of a muscle using a miniature piezoelectric transducer
-
Electromyography (EMG) measures the electrical activity (compound muscle action potential) of a stimulated muscle
-
Kinemyography (KMG) detects the acceleration of the thumb contraction in response to electrical stimulation of a nerve
Pregunta 11
Pregunta
All of the following are examples of Benzylisoquinolinium compounds consist of two quaternary ammonium groups joined by methyl groups EXCEPT:
Respuesta
-
D-tubocurarine
-
Atracurium
-
Mivacurium
-
Pancuronium
-
Cisatracurium
Pregunta 12
Pregunta
Train-of-four (TOF) has all of the following characteristics, EXCEPT:
Image:
Tof (binary/octet-stream)
Respuesta
-
TOF consists of four ST stimuli at a frequency of 4 Hz
-
TOF does not require a “baseline” or “control” muscle response
-
TOF “fade” is defined as a weaker fourth twitch than the first twitch
-
TOF is delivered every 15-20 sec to prevent potentiation of subsequent responses
-
TOF ratios >0.40 cannot be reliably detected subjectively (visually or tactilely)
Pregunta 13
Pregunta
Double burst stimulation (DBS) characteristics include all of the following, EXCEPT:
Image:
Dbs (binary/octet-stream)
Respuesta
-
The two mini-tetanic bursts are separated by 0.5 sec
-
DBS is delivered no more frequently than every 20 sec to prevent subsequent response potentiation
-
In DBS, similar to TOF pattern, no control (“baseline”) muscle response is needed
-
DBS ratios >0.60 cannot be reliably detected by subjective (tactile, visual) means
-
In awakening patients, DBS is more painful than TOF, but less so than tetanic stimulation
Pregunta 14
Pregunta
Potential side-effects associated with the use of succinylcholine include all of the below, EXCEPT:
Respuesta
-
Myalgia
-
Tachycardia
-
Anaphylaxis
-
Hyperkalemia
Pregunta 15
Pregunta
Since sugammadex has no direct cholinergic properties, anesthesiologist do not require the ready availability of an anticholinergic like glycopyrrolate at the time of reversal.
Respuesta
- True
- False
Pregunta 16
Pregunta
When administering sugammadex through a peripheral IV, it is important to note that the drug has a physical incompatibility with all of the following drugs except:
Respuesta
-
Verapamil
-
Dexamethasone
-
Ranitidine
-
Odansetron
