Question 1 of 5
A nurse is preparing to administer ceftriaxone 1 g IM every 12 hr. Available is ceftriaxone injection 450 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth.)
Correct Answer: 2.2
Rationale:
To calculate the mL needed for each dose of ceftriaxone 1g IM, we divide the total dose by the concentration of the injection: 1g = 1000mg. So, 1000mg รท 450mg/mL = 2.22 mL. Rounding to the nearest tenth gives us 2.2 mL. This ensures the correct dosage is administered. The other choices are incorrect because they do not accurately calculate the mL required for the 1g dose of ceftriaxone based on the concentration of the injection.
