Answer : 0.6 mL
Explanation : Bicillin is given by deep IM injection into upper outer quadrant of buttock region; rotatation of injection sites should be done. Upper
respiratory Group A strep : 1.2 million units once should be prescribed.
In Syphilis (primary, secondary, latent treatment) : 2.4 million units once is given; (In tertiary and neurosyphilis) : 2.4 million units every 7 days for 3 doses is given.
For Rheumatic heart disease and acute glomerulonephritis : 1.2 million units once per month is given, or 600,000 units every 2 weeks.
So bicillin 600,000 units/ 1.2 mL vial should be 0.6 mL Im q 12 hrs.
300,000/600,000 = 2; therefore 1.2/2 = 0.6 mL
