two more math questions

[Reese2012]

Digoxin 2 gm has been ordered. Digoxin is available in 250mg per 5mL. How many tbsp should be given?

I have tried taking 2gm/1000 or taking 250*1000 then taking that number and multiplying by 5mL but nothing seems to come out right to factor in the tbsp.

Am I missing something here?

5ml of digoxin has been ordered. This is equivalent to how many grams?

I dont even know where to begin with this one!

Start with how many milligrams are in a gram. You have 2 GRAMS ordered and on hand is 250 MILLIgrams. Your units need to match.

[JustBeachyNurse, LPN]

How many teaspoons in a tablespoon? 1 teaspoon = 5mL.

[TalarossaRN]

2000mg/250mg = 8*5 ml = 40 ml = 8 tsp or 2.67 tbsp

ok I see now

What about the second question? I dont know how to set the problem up.

[TalarossaRN]

1 ml= 1 gram so 5ml= 5 grams

[AmyRN303, BSN, RN]

ok I see now

What about the second question? I dont know how to set the problem up.

Your original says dig is available in 250 mg/5 mL. So, if 5 mL is ordered, how many grams is 250 mg?

For the second question if it's using the info from the first then:

250mg / (1g/1000mg) = 0.25g

So 5ml=250mg=0.25g

5ml of digoxin has been ordered. This is equivalent to how many grams?

for the second question on this practice test I am taking this is all it states. Did the prof not put enough info in this problem or can I still somehow figure out the answer?

[Reese2012]

so would the answer to second question be 5?

[Reese2012]

thank you

[Cris_tal1303]

If the second question does not state something other than what's 5ml in grams than there is info missing. Not all meds have the same ml per g dose. That's why I uses the info from the 1st question I assumes it was a two part question using the same info.
