Deck 8: Solutions

Question 1

The nurse is preparing a solution that is 1 part solute in 5 parts solution.What the strength of this solution as a percentage:
Standard Text: Record your answer using a whole number.

Answer 1

20 %
Explanation:Solute/solution = solute/solution = 1/5 = 0.2 x 100 = 20%.

Question 2

The nurse is preparing a bottle feeding for a newborn.How many mL of ½ strength Similac can be made from one 8 ounce bottle of the solution?
1)120 mL
2)240 mL
3)360 mL
4)480 mL

Answer 2

4
Explanation:The nurse should use the equation 8 ounces (full strength)x 2 ounce solution/1 ounces full = 16 ounces of bottle feeding.To determine the number of mL multiply the total number of ounces x 30 or 16 x 30 = 480 mL.
