1
Q
Resting potential of the skeletal muscle cell?
A
−90 mV
2
Q
The most accurate explanation behind the “faster onset” of rocuronium?
A
Rocuronium is LESS POTENT with ED95 of 0.3mg/kg
[The rate of onset of nondepolarizing NMBs generally depends on their potency]
3
Q
The fast onset of CHLOROPROCAINE is due to what property?
A
Concentration
4
Q
A TOF ratio of <0.4 means which of the following?
A
A. patients cannot lift their arms
B. vital capacity is reduced but most cannot lift their heads for 3 seconds
C. most vital capacity is normal but many may have diplopia
D. Full recovery is expected
A
5
Q

A
Ketamine S+ form is most potent
* has half life of 2-3 hours
* highly lipid soluble
* metabolite is Norketamine and is 1/3 as potent
