To prevent hyperK-induced arrythmias in symptomatic hyperK, what should be administered preferably? (drug and dose)
How much plasma K is reduced in the process?
Ca gluconate 1g=10ml IV peripherally over 2-10mins, may rpt in 5min if no improvement in EKG
FYI preferred over CaCl b/c dec risk of tissue necrosis, although elemental Ca level is lower
Plasma K levels will NOT be reduced, but it does antagonize efx of K in cardiac conduction cells
