1) 100ml
2) 150 ml
3) 200 ml
4) 300 ml

Answer 1

To dispense the correct amount of Ceclor suspension (125mg/6ml) for the prescription of 175 mg taken three times daily for 10 days, one must calculate the volume for a single dose and the total volume required for all doses. The total volume needed is 252 ml, therefore the appropriate quantity to dispense is 300 ml.

Step-by-step explanation:

The question is asking to calculate the appropriate quantity of Ceclor suspension to dispense, based on the prescription which specifies a dosage of 175 mg taken three times a day (tid) for 10 days. Since the available suspension is 125 mg per 6 ml, we first determine how many milliliters are needed for a single dose and then multiply that by the number of doses to cover the 10 days.

To find out how many milliliters are needed for one dose of 175 mg, we set up a proportion:
(125 mg / 6 ml) = (175 mg / x ml), which solves to x = (175 mg * 6 ml) / 125 mg = 8.4 ml per dose.

Next, we calculate the total volume needed for 10 days at three doses per day, which is 8.4 ml per dose * 3 doses per day * 10 days = 252 ml. Since the options provided do not include 252 ml, the correct choice is the one that can cover 252 ml, which is 300 ml (option 4).
