Question 1 of 5
A nurse is preparing to administer 150 mg of an antibiotic IM. Available is 2 g/10 mL. Haw many mi should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 0.8 mL
Rationale:
To determine the correct answer, first, convert 150 mg to grams (150 mg = 0.15 g).
Then, calculate how many milliliters of the antibiotic contain 0.15 g by setting up a proportion: 2 g is in 10 mL, so 0.15 g is in x mL. Solving for x gives us 0.75 mL. However, since the question asks for the answer rounded to the nearest tenth, the nurse should administer 0.8 mL per dose. The other choices are incorrect because they are not the result of the accurate conversion and calculation process.
