Question 52

The amount that should be administered to a patient who needs 1/4 of a one-liter bottle is 250 mL.

To determine the amount needed, one must calculate 1/4 of one liter, which equals 250 milliliters.

A) 250 L

This option is incorrect because 250 liters is an excessively large volume that far exceeds the requirement of 1/4 of a one-liter bottle. One liter is equivalent to 1,000 milliliters, and 250 liters would be 1,000 times that amount.

B) 250 mL

This is the correct answer as it accurately represents 1/4 of one liter. Since one liter equals 1,000 milliliters, dividing that by four gives 250 milliliters.

C) 500 mL

This option is incorrect because 500 milliliters is half of one liter, which is twice the required amount for 1/4 of a one-liter bottle. Therefore, administering 500 mL would exceed the necessary dosage.

D) 500 L

This option is also incorrect as 500 liters is an impractically large volume. It would be 500 times the required amount for 1/4 of a one-liter bottle and is not a feasible dosage for any patient.

Conclusion

The correct administration amount is 250 mL, which precisely matches the calculation for 1/4 of a one-liter bottle. All other options either significantly exceed or do not meet the needed volume, confirming that B is the only viable choice.
