Final answer:
A cat weighing 3 kg requires a medication dosage of 1 mg/kg b.i.d. (twice a day) for 10 days. The tablets available are 2 mg each, so 30 tablets are needed to complete the 10-day course.
Step-by-step explanation:
To calculate the number of tablets to be dispensed for the 3 kg cat needing medication at a dose rate of 1 mg/kg b.i.d for 10 days, we first determine the total dosage required. The cat's weight is 3 kg, so each dose should be 3 mg (as it's 1 mg/kg). Since the medication is to be given b.i.d. (twice a day), the cat will need 6 mg per day. Over 10 days, the cat will thus require a total of 60 mg of medication.
Given that the tablets on hand are 2 mg each, we divide the total required dosage by the dosage per tablet: 60 mg ÷ 2 mg/tablet = 30 tablets. Therefore, to administer the correct dosage over the 10-day period, 30 tablets should be dispensed.
To calculate the number of tablets that should be dispensed, we need to find the total dose of medication required for the 10-day period. The cat's weight is 3 kg and the dose rate is 1 mg/kg b.i.d. Therefore, the total daily dose is 3 kg x 1 mg/kg = 3 mg.
Since the medication needs to be given twice a day (b.i.d.), the cat will receive a total daily dose of 3 mg x 2 = 6 mg.
For a 10-day period, the cat will require a total dose of 6 mg x 10 days = 60 mg.
The tablets on hand are 2 mg each. To calculate the number of tablets needed, we can divide the total dose by the dosage strength:
Number of tablets = 60 mg / 2 mg = 30 tablets.
Therefore, the correct answer is A. 30 tablets.
