A client with heart failure is prescribed a fluid restriction of 500 mL per 8 hour shift. When the client is discharged home, how many cups of fluid will the nurse teach the client that can be ingested every day?
1. 2
2. 4
3. 6
4. 8
3
Rationale 1: Cups per day = 2 cups/500 mL x 500 mL/ 8 hours x 24 hours/1 day. Multiply the numerators (2 x 500 x 24 = 24,000). Multiply the denominators (500 x 8 x 1 = 4,000). 24,000/4,000 = 6 cups per day.
