ATI TEAS (Test of Essential Academic Skills) Version 7MathematicsMedium
A client is instructed to drink 2.5 liters of water daily. If they have already consumed 750 mL in the morning and 1.2 liters in the afternoon, how many more milliliters of water do they need to drink to meet their daily goal?
- A650 mL
- B750 mL
- C800 mL
- D550 mL
Show answer & explanationAnswer & explanation
Correct answer: D. 550 mL
First, convert all volumes to milliliters for consistency. The daily goal is 2.5 liters * 1000 mL/L = 2500 mL. The client has consumed 750 mL + (1.2 liters * 1000 mL/L) = 750 mL + 1200 mL = 1950 mL. To find out how much more is needed, subtract the consumed amount from the goal: 2500 mL - 1950 mL = 550 mL.
Why the other options are wrong
- A. This indicates a calculation error, possibly in conversion or subtraction.
- B. This suggests a significant miscalculation, perhaps only subtracting one of the consumed amounts.
- C. This is an overestimation, likely due to an error in adding consumed amounts or subtracting from the goal.
Fluid Intake Calculation (Mixed Units)
Calculating the remaining fluid intake needed to meet a daily goal, involving conversion between liters and milliliters.
- Ensure all fluid measurements are in the same unit (e.g., mL).
- Sum the fluid already consumed.
- Subtract the consumed amount from the total daily goal.
Memory trick: Convert all to ML, add what's consumed, then subtract from the goal.
