A 5-year old Labrador has developed hemorrhagic gastroenteritis. The clinician has instructed you to
start him on Metronidazole at a dose of 10 mg/kg intravenously twice daily. Metronidazole is available
in a 5 mg/ml solution. How many milliliters are necessary per dose? The dog's body weight is 80 lbs. -
correct answers73 ml
First, convert the dog's body weight to kilograms.
80 lbs / (2.2 lbs/kg) = 36.4 kg
Now determine how many milligrams are necessary per dose.
36.4 kg x (10 mg/kg) = 364 mg (notice the kilograms cancel out)
Finally, determine how many milliliters are in 364 mg.
364 mg / (5 mg/ml) = 73 ml (notice the milligrams cancel out)
A 20-kg patient is currently receiving 52 ml/hr of Lactated Ringer's Solution. The clinician has requested
that 2 mg/kg/day of metoclopramide be added to the bag. Metoclopramide is available as a 5 mg/ml
solution. How many milliliters do you need to add to a 1 liter bag? - correct answersThis is definitely a
more complicated calculation question, but when broken down it is not insurmountable.
A 20-kg patient will need 40 mg/day of metoclopramide (20 kg x 2 mg/kg/day)
Since the fluid is being administered at an hourly rate, we need to figure out how much metoclopramide
we are administering per hour.
, 40 mg/day / (24 hr) = 1.7 mg/hr
To determine how much volume of metoclopramide is needed, the following math is performed:
1.7 mg/hr / (52 ml/hr) x (1000 ml)= 32.6 mg (Notice how the units cancel out.)
32.6 mg / (5 mg/ml) = 6.5 ml
What quantity of drug is found in 200 mLs of a 10% solution? - correct answers20 grams
A 10% solution is equal to 100 mg/mL. The easiest way to remember this conversion is to add a zero to
the percentage. (10%= 100 mg/mL, 15% = 150 mg/mL, etc.)
If 1 mL is equal to 100 mg, then to find out the quantity of drug in 200 mLs, multiply 100 mg X 200 =
20,000 mg. There are 20,000 mg in 200 mLs of a 10% solution.
But none of the choices are 20,000 mg. We need to go one step further and determine how many grams
this is.
1 gram is equal to 1,000 mg. We need to divide the milligrams by 1,000.
So, 20,000mg / 1,000 = 20 grams.
You want to give a pre-surgical dose of antibiotics to your patient. You have a 1 gram vial of cefoxitin
that is reconstituted with 5 mls of sterile water. You want to give a 20 mg/kg dose to a 25 kg dog. How
many mls do you give? - correct answers2.5mL
Explanation
The resulting concentration of the cefoxitin solution is 1gm/5ml or 200mg/ml.
The desired dose is 20mg/kg x 25 kg = 500 mg
