Question 1 of 5
The client has an order for 0.45 mg of Diltiazem. The medication vial has a concentration of 3 mg/mL. How many mL of the drug should be administered?
Correct Answer: A
Rationale:
To calculate the amount of drug to be administered, divide the ordered dose by the concentration of the medication in the vial. In this case, 0.45 mg ÷ 3 mg/mL = 0.15 mL.
Therefore, the correct answer is 0.15 mL.
Choice B (6.6 mL) is incorrect as it does not result from the correct calculation.
Choice C (1.5 mL) is incorrect as it is not the result of dividing the ordered dose by the concentration.
Choice D (0.65 mL) is incorrect as it is not the accurate calculation based on the provided information.
