If a dosage of 6,500 units of a medication are ordered, and the available strength is 10,000 units per mL, how many mL must be administered?

0.3 mL
0.5 mL
0.7 mL
0.9 mL

0.7 mL

Rationale: To determine how many mL must be administered, divide the dosage of 6,500 units by the available strength of 10,000 units, which equals 0.65 . Multiply by 1 mL to find 0.65 mL. Given the answer choices in this question, we must round up to 0.7 mL, which is the amount that must be administered.
