A nurse is preparing to administer ziprasidone 10 mg IM every 6 hr. Available is ziprasidone 20 mg/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.)
Correct answer
0.5
Rationale
Correct Answer: 0.5
Rationale:
1. First, calculate the total dose needed per administration: 10 mg.
2. Next, determine how many mL of the 20 mg/mL solution will provide 10 mg of ziprasidone: 10 mg / 20 mg/mL = 0.5 mL.
3. Therefore, the nurse should administer 0.5 mL of ziprasidone per dose.
Summary:
- Choice A: Incorrect, as it does not reflect the correct calculation based on the provided information.
- Choices B-G: Irrelevant, as they do not involve the correct calculation for determining the mL of ziprasidone needed for the dose.
