Bicillin 300,000 units im q 12 hrs. on hand: bicillin 600,000 units/1.2ml vial give : ml im q 12 hrs.

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

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
