Question 1 of 5

A nurse is preparing to administer vitamin K 1mg IM to a newborn. Available is vitamin K injection 1 mg/0.5 mL. How many mL 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.)

A. 0.5 mL B. 0.1 mL C. 1.0 mL D. 0.25 mL

Correct Answer: A

Rationale: The correct answer is A: 0.5 mL.
To determine the mL to administer, we use the formula: Dose required (1 mg) divided by Dose available (1 mg/0.5 mL), which equals 0.5 mL. This calculation ensures the correct dosage is administered. The other choices are incorrect because B (0.1 mL) is too low, C (1.0 mL) is double the correct dose, and D (0.25 mL) is half the required dosage.
Therefore, A (0.5 mL) is the appropriate amount for administering vitamin K 1mg IM to a newborn.
