When comparing deciliters and centiliters, which unit represents the smaller quantity?
centiliters
Neither represents a smaller quantity
Both are equal
Deciliters
The Correct Answer is A
Rationale:
A. centiliters: A centiliter is 1/100 of a liter, whereas a deciliter is 1/10 of a liter. Since 1/100 is smaller than 1/10, centiliters represent a smaller quantity compared to deciliters. This makes centiliters the more precise, smaller unit when measuring volume.
B. Neither represents a smaller quantity: Both units measure volume, but their sizes differ. Deciliters are larger than centiliters, so it is inaccurate to say neither is smaller. Understanding metric prefixes helps clarify which unit is smaller.
C. Both are equal: Centiliters and deciliters are not equal in size. One deciliter equals ten centiliters, meaning their volumes are different. Recognizing metric relationships prevents confusion in conversions and measurements.
D. Deciliters: A deciliter represents 1/10 of a liter, which is larger than a centiliter (1/100 of a liter). Choosing deciliters as the smaller unit would be incorrect because they contain a greater volume than centiliters.

Correct Answer is C
Explanation
Calculation:
Ordered Dose = 0.5 g
Available Dose = 250 mg
- Convert Ordered Dose to mg
Ordered Dose = 0.5 × 1000 = 500 mg
Number of tablets = Ordered Dose / Available Dose
= 500 / 250
= 2 tablets
Correct Answer is D
Explanation
Calculation:
Ordered Dose = 500 mg
Available Dose = 250 mg
Available Volume = 5 mL
Volume to administer = (Ordered Dose / Available Dose) × Available Volume
= (500 / 250) × 5
= 2 × 5
= 10 mL
