A client is receiving 100 mL of intravenous fluid for 18 hours. How many liters of fluid did the client receive?

- 1.2
- 1.5
- 1.8
- 2.2

Correct Answer: 3

Rationale 1: L = 1 L/1000 mL x 100 mL/1 hr x 18 hr/1. Multiply all the numerators (1 x 100 x 18 = 1800). Multiply all the denomenators (1000 x 1 x 1 = 1000). 1800/1000 = 1.8. The mL and the hrs cancel each other out, which leaves the label of the answer as L. The client received 1.8 L of intravenous fluid.

Rationale 2: L = 1 L/1000 mL x 100 mL/1 hr x 18 hr/1. Multiply all the numerators (1 x 100 x 18 = 1800). Multiply all the denomenators (1000 x 1 x 1 = 1000). 1800/1000 = 1.8. The mL and the hrs cancel each other out, which leaves the label of the answer as L. The client received 1.8 L of intravenous fluid.

Rationale 3: L = 1 L/1000 mL x 100 mL/1 hr x 18 hr/1. Multiply all the numerators (1 x 100 x 18 = 1800). Multiply all the denomenators (1000 x 1 x 1 = 1000). 1800/1000 = 1.8. The mL and the hrs cancel each other out, which leaves the label of the answer as L. The client received 1.8 L of intravenous fluid.

Rationale 4: L = 1 L/1000 mL x 100 mL/1 hr x 18 hr/1. Multiply all the numerators (1 x 100 x 18 = 1800). Multiply all the denomenators (1000 x 1 x 1 = 1000). 1800/1000 = 1.8. The mL and the hrs cancel each other out, which leaves the label of the answer as L. The client received 1.8 L of intravenous fluid.

Global Rationale: L = 1 L/1000 mL x 100 mL/1 hr x 18 hr/1. Multiply all the numerators (1 x 100 x 18 = 1800). Multiply all the denomenators (1000 x 1 x 1 = 1000). 1800/1000 = 1.8.
