Dosage Calculations Chapter 5 (2022/2023) Already Passed 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.) A drug label reads "1 tablet equals 50 milligrams". How many grains would this be? a. 0.5 grain b. 1.5 grains c. 2 grains d. 1 grain ✔✔d. 1 grain (Rationale: Sixty milligrams is equivalent to 1 grain.) True or False: Clark's rule is commonly used today to calculate pediatric drug dosages, but Young's rule is rarely used. ✔✔False (Rationale: Clark's rule, Young's rule, and Fried's rule are not commonly used to determine pediatric doses. Body surface area or milligrams per kilogram of body weight are most commonly used.) [Show More]
