Question

A nurse is converting an infant's weight from lb to kg. If the infant weighs 10 lb 4 oz, what is the infant's weight in kg?

a) 4.5 kg
b) 4.2 kg
c) 4.7 kg
d) 5.0 kg

Answer 1

To convert an infant's weight from pounds (lb) to kilograms (kg), multiply the weight in pounds by 16 and add the weight in ounces. Then, divide the total weight in ounces by 35.36 to get the weight in kilograms. In this case, the infant weighs approximately 4.65 kg.

Step-by-step explanation:

To convert an infant's weight from pounds (lb) to kilograms (kg), you need to use the conversion factor of 1 lb = 0.4536 kg.

First, convert the weight in pounds to ounces by multiplying the number of pounds by 16.

Then, convert the total weight in ounces to kilograms by multiplying it by the conversion factor.

In this case, the infant weighs 10 lb 4 oz, which is equivalent to (10 x 16) + 4 = 164 oz.

Now, divide 164 by 35.36 to get the weight in kilograms. The infant's weight is approximately 4.65 kg.
