brief analysis of the options (again

)

a) true. but so does 0.5 and 1% bupivacaine. widely used minimal concentration is 0.125%
b) false. bupivacaine may be used for IVRA but not recommended over lidocaine. bupivacaine has greater cardiotoxicity and does not offer any advantage over lidocaine. the analgesia duration in IVRA is linked to the isolated limb circulation rather than the duration of action of the LA
c) false. methaemoglobinaemia is caused by prilocaine
