Deck 14: Drug Calculations

Question 1

The nurse weighs the newborn infant and determines the weight to be 3.2 kilograms. How many grams does the newborn infant weigh?
________ grams
Record the answer rounding to the nearest whole number.

Answer 1

3,200
Explanation:When converting from kilograms to grams, the decimal point is moved three points to the right, or 3,200 grams. When converting from a smaller measurement (milligrams) to a larger measurement (grams), the decimal point moves to the left; when converting from larger to smaller, the decimal point moves to the right.

Question 2

The nurse is weighing a pediatric client who weighs 8.3 kilograms. The mother asks what that is in pounds and ounces. The nurse would tell the mother the child's weight in pounds is: ________ pounds.
Record the answer rounding to the nearest tenth.

Answer 2

18 pounds, 4.16 ounces, or 18.26 pounds or 18.3
Explanation:In order to calculate the child's weight in pounds, the nurse must know that there are 2.2 kg in 1 pound. 8.3 × 2.2 = 18.26 lb. 0.26 lb can be converted to ounces by multiplying 0.26 by 16 = 4.16 ounces.
