Deck 19: Reconstitution of Solutions

Question 1

Order: Ancef 0.375 g IM q6h
Available:
a.How many milliliters of diluent will you add? _____ mL
b.What is the dosage strength of the reconstituted solution? _______________
c.How many milliliters will you administer? _____ mL

Answer 1

a.2
b.225 mg per mL
c.1.7

Question 2

1/4 strength Ensure 8 oz p.o.q4h for 24 hours

Answer 2

[Note: 8 oz q4h = 6 feedings; 8 oz $\times$ 6 = 48 oz]
1 oz = 30 mL,therefore 48 oz = 1,440 mL
1/4 $\times$ 1,440 = 360 mL of the formula (solute)
Amount of solution (1,440 mL)- Amount of solute (360 mL)= Amount needed to dissolve (1,080 mL)
Therefore,you will add 1,080 mL of water to 360 mL of Ensure to make 1440 mL of 1/4 strength Ensure.
