True or False: One tablespoon is equivalent to 30 milliliters. ✔✔False




(Rationale: One tablespoon is equivalent to 15 milliliters.)




Six fluid ounces are equivalent to how many milliliters?

a. 120 mL

b. 180 mL

c. 240 mL


d. 60 mL ✔✔b. 180 mL




(Rationale: One fluid ounce is equivalent to 30 mL. Using this conversion, the nurse would set

up the following ratio and proportion: 1 f oz/30 mL = 6 f oz/X mL. Cross multiplying and

solving for X: X = 180 mL.)




A patient is to receive 150 mL of intravenous solution over the next hour using a microdrip

delivery system. How much fluid would the patient receive in 1 minute?

, a. 2.5 mL

b. 1.5 mL

c. 4.5 mL


d. 3.0 mL ✔✔a. 2.5 mL




(Rationale: The nurse would divide 150 mL by 60 minutes, which would result in 2.5 mL per

minute.)




A child is to receive 500 mg of an antibiotic suspension. The label on the bottle reads 250 mg/5

mL. The nurse would administer how much of the suspension in one dose?

a. 2.5 mL

b. 7.5 mL

c. 5 mL


d. 10 mL ✔✔d. 10 mL




(Rationale: To determine the amount to give, the nurse would set up the following ratio and

proportion: 250 mg/5 mL = 500 mg/X mL. Cross multiplying and solving for X: 250X = 5 x 500;

X = 10 mL.)
