Question 33

The daily volume of lactulose syrup is 45 mL.

Lactulose syrup is typically dosed at 1 tablespoon three times a day. Since 1 tablespoon is equivalent to approximately 15 mL, the total daily volume can be calculated as 15 mL multiplied by 3, resulting in a total of 45 mL.

A) 15

This option represents the volume of lactulose syrup per single dose (1 tablespoon). However, it does not account for the total daily volume when taken three times a day, making it an incorrect choice.

B) 30

This option could represent two doses of lactulose syrup (2 tablespoons), but it does not reflect the total daily intake of three doses, which is required for accurate calculation. Therefore, this option is incorrect.

C) 45

This option is correct as it represents the total daily volume of lactulose syrup. With 1 tablespoon (15 mL) taken three times a day, the total volume is indeed 45 mL.

D) 60

This option exceeds the total daily volume calculated from the prescribed dosage. It would represent four doses of lactulose syrup rather than three, making this option incorrect.

Conclusion

The correct answer, 45 mL, accurately reflects the total daily volume of lactulose syrup when taken three times a day at 1 tablespoon per dose. All other options fail to provide the correct calculation based on the prescribed dosing regimen. Thus, option C is the only valid choice in this context.
