An antibiotic is reconstituted with 128ml of water to yield 250mg/5ml.

A) If the child weighs 66 pounds what will the dose be at 5mg/kg/dose?
B) If the medication is given qid x 10 days, will the 150ml bottle be enough?

You need to convert pounds to kg to solve A. Then multiply it by the 5 mg to get total mg/dose.

250mg/5ml = total mg/?ml for A.

150/(total[?] ml*4*10) will answer B.

I hope this helps. Thanks for asking.

To determine the answers to these questions, we'll need to perform some calculations using the given information. Let's break it down step by step:

A) To calculate the dose for a child weighing 66 pounds at 5mg/kg/dose:
1. First, we need to convert the weight from pounds to kilograms. Since 1 kilogram is approximately equal to 2.2 pounds, the child weighs approximately 66/2.2 = 30 kilograms.
2. Next, we need to calculate the dose. The dose is given as 5mg per kilogram, so the dose for a 30-kilogram child would be 5mg/kg * 30kg = 150mg.

Therefore, the dose for the child weighing 66 pounds at 5mg/kg/dose would be 150mg.

B) To determine if the 150ml bottle would be enough for qid (four times a day) administration for 10 days:
1. First, we need to calculate the total dose required for 10 days. Since the dose is 150mg per dose and administered four times a day, the total daily dose is 150mg per dose * 4 doses = 600mg.
2. Multiply the total daily dose by the number of days to get the total dose required for 10 days. The total dose required would be 600mg * 10 days = 6000mg.
3. Since the reconstituted antibiotic concentration is 250mg/5ml, we can find the required volume of the medication by dividing the total dose required by the concentration: 6000mg / 250mg/5ml = 120ml.

Therefore, the 150ml bottle would be enough to administer the medication qid for 10 days, as the required volume is only 120ml.
