Clinical Medical Assistant Certification Exam Practice Question
A physician prescribes 400 mg of an antibiotic. The concentration of a drug Is Indicated as 200 mg/mL on the bottle. Which of the following Is the most appropriate volume of the antibiotic to draw?
Correct Answer: C
Rationale: To determine the appropriate volume of antibiotic to draw, the total required dose (400 mg) must be divided by the concentration (200 mg/mL).
Calculating this gives:
400 mg ÷ 200 mg/mL = 2.0 mL.
This makes option C the correct choice.
Option A (0.5 mL) would only provide 100 mg, which is insufficient.
Option B (1.5 mL) would yield 300 mg, still below the required dose.
Option D (3.0 mL) would provide 600 mg, exceeding the prescribed amount.
Option E (4.0 mL) would provide 800 mg, which is also too much.
Thus, only option C accurately meets the prescription.
