A resident's intake for the shift includes 240 mL of water, 180 mL of coffee, and 120 mL of soup. What is the total fluid intake in milliliters?
- A540 mL
- B420 mL
- C660 mL
- D600 mL
Show answer & explanationAnswer & explanation
Correct answer: A. 540 mL
Adding the fluid amounts: 240 mL + 180 mL + 120 mL = 540 mL total intake. All liquid or semi-liquid foods consumed count toward fluid intake.
Why the other options are wrong
- B. This total is too low; recheck the addition of all three amounts.
- C. This total overestimates the actual sum of the amounts listed.
- D. This total is too high for the given values.
Fluid Intake Calculation
Total fluid intake is calculated by adding all liquids and liquid foods (like soup, ice cream, gelatin) consumed during a given period, usually recorded in milliliters (mL).
- Add all liquid amounts consumed to get total intake
- Soup, gelatin, ice cream count as fluid intake
- 1 oz = approximately 30 mL for conversions
Memory trick: 'Add it all up, drop by drop!'
