Simulated
A nurse is preparing to administer 7 mg of haloperidol IM to a client who is severely agitated. Haloperidol injection of 5 mg/mL is available. 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
1.4
Rationale
To determine the mL needed, divide the total dose by the concentration of the medication. In this case, 7 mg / 5 mg/mL = 1.4 mL. The correct answer is 1.4 mL. Choice A, 2.5 mL, is incorrect as it is not the result of the correct calculation. Choices B, C, D, E, F, and G are also incorrect as they do not reflect the accurate calculation based on the dose and concentration provided.
