3. ordered: 30 mg furosemide available: 40 mg/2ml. how many milliliters will be given?

ordered: acetaminophen 250 mg available: 500 mg tablets. how many tablets will be given?

ordered: 300 mg rocephin available: 500 mg/ 10 ml. how many ml will be give?

1.5ml of furosemide solution, half of acetanimophen tablet and 6ml of Rocephin will be given.

Explanation:

The furosemide injection contains a concentration of 40mg/2ml of the injectable. The patient, according to his body weight needs an amount of 30mg of furosemide. So he will need 2*30/40 ml of the injectable = 1.5ml of the injectable.

The acetanimophen tablet has an active composition of 500mg. But the patient needs the amount of 250mg of acetanimophen. So the patient will take 250/500 tablets =0.5 tablet.

The Rocephin injectible contains a concentration of 500mg/10ml of the injectable. But the patient needs 300mg of Rocephin. So he will take 10*300/500= 6ml of the injectable.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
