A nurse is preparing to administer lidocaine 50 mg IV bolus. Available is lidocaine 200 mg/mL. How many mL should the nurse administer (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct answer
A
Rationale
The correct answer is A: 0.3 mL. To calculate the volume to be administered, you divide the desired dose by the concentration of the medication:
50 mg ├À 200 mg/mL = 0.25 mL. Since the answer needs to be rounded to the nearest tenth, the correct answer is 0.3 mL.
Choice B and the other options are incorrect as they do not accurately calculate the volume required based on the given dose and concentration of lidocaine.
