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.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
