2. child takes 12ml of drug 4x/day bottle has 16oz. how long will bottle last?

3. weight of baby is 10lbs and length is 21.5 inches- how many kg and cm is baby?

Answer 1

1)

1 pound = 0.454 kilogram

Given, child weighs 55lbs

Convert lbs to kilogram by multiplying it by 0.454

We get weight= 55 x 0.454 = 24.97 kg

Given, Dosage is 0.05 mg per kg

So child should get a dose of 0.05 x 24.97 = 1.2485 mg

When this is rounded to 2 decimal points, answer will be 1.25 mg

2)

Given, the bottle has 16 oz

1 oz = 29.574 mL

So the bottle contains 16 x 29.574 = 473.176 mL

Child takes 12 mL 4 times a day. So a total of 48 mL per day.

Number of days drug lasts can be calculated by 473.176/48 = 9.85 days

That is the child should by a new bottle on the 10th day

3)

1 pound = 0.454 kilogram

Given, the weight of the baby is 10lbs

Weight in kg = 10 x 0.454 = 4.54 kg

1 inch = 2.54 cm

Height is 21.5 inches

Height in cm = 21.5 x 2.54 = 54.61 cm up
