A pet needs 5mg/kg of Albon po sid on day 1, then 2.5mg/kg po sid for 5 more days. The medication is available in 125mg tablets and the pet weighs 25#. How many tablets will be dispensed for the owner?
25# / 2.2#/kg = 11.36kg 11.36kg x 5mg/kg = 56.8mg on day 1 56.8mg / 125mg = 0.045 tabs or 1/2 tablet for day 1 11.36kg x 2.5mg/kg = 28.4mg on days 2-6 28.4mg / 125mg = 0.22 tables or 1/4 tablets for days 2-6 Answer = 2 tablets
A pet needs 25mg of a 2% solution. How many mL will be administered? 2% solution = 20mg/mL
25mg / 20mg/mL = 1.25mL Answer = 1.25mL
A cockatiel needs 80mg/kg piperacillin via IM injection. If the bird weighs 30g, and the concentration of drug is 100mg.mL, how many mL should be administered?
30g / 1000g/kg = 0.03kg 0.03kg x 100mg/kg = 3mg 3mg / 100mg/mL = 0.03mL Answer = 0.03mL
A dose of 30 mEq KCl has bee added to 1L of normal saline. What drip rate would provide a patient with 1 mEq KCl/hr?
30mEq = 0.03mEq/mL 2mEq / 0.03mEq/mL = 67mL/hr Answer = 67mL/hr
A pet needs 35mg of a solution, and the medication is available as a 100mg/mL solution. How many mL will be needed?
35mg / 100mg/mL = 0.35mL Answer = 0.35mL
A patient requires 3 units of insulin every 12 hours. If the concentration of insulin is 100units/mL, how many mL should be given at each administration?
3units / 100units/mL = 0.03mL Answer = 0.03mL/administration
A dose of 40mEq KCl has been added to 1L of normal saline solution. What drip rate would provide a patient with 1mEq KCl/hr?
40mEq/L = 0.04mEq.mL 1mEq / 0.04mEq/mL = 25mL/hr Answer = 25mL/hr
A dog consumes 5 bowls of water in a 24 hour period. Each bolt contained exactly 100mL. If you collect 475mL of urine over the same 24 hour period, approximately how many mL constitute insensible loss?
5 bowls x 100mL = 500mL 500ml - 475mL = 25mL Answer = 25mL
A dog weighs 55#. what is its weight in kg?
55# / 2.2#/kg = 25kg Answer = 25kg
A commercial cat food is 160kcal/cup. A cat weighing 6# fed at a rate of 40callories/#/day should be fed how many cups at each meal if you feed him twice a day?
6# x 40kcal/#/day = 240kcal/day 240kcal / 160kcal/cup = 1.5 cups 1.5cups/ 2 feedings/day = 0.75 cups/feeding or 3/4 cup Answer = 3/4 cup/feeding
A commercial dog food is 420kcal/cup. A dog weighing 60# fed at a rate of 70kcal/#/day should be fed how many cups at each meal if he is fed twice daily?
60# x 70kcal/#/day = 4200kcal/day 4200kcal / 420kcal/cup = 10 cups 10 cups / 2 feedings/day = 5 cups/feeding Answer = 5 cups/feeding
A doctors order calls for prednisone at a dosage of 2mg/kg to be delivered orally ro a 7.5kg cat. how many tablets or prednisone would you administer to the cat?
7.5kg x 2mg/kg = 15mg 15mg / 5mg = 3 tabs Answer = 3 tablets **Fun Fact** PredniSONE is the active form of this particular drug. It also comes in PrednisoLONE which cats cannot biotransform into its active form of PredniSONE therefor PrednisoLONE cannot be given to cats but PredniSONE can be given to cats! ^We have both at the clinic I work at so be very careful that you are getting the correct drugs for the correct animals!!
