Question 1 of 5
A nurse is preparing to administer haloperidol 5 mg IM to a client. The amount available is haloperidol 20 mg/mL. How many mL should the nurse administer?
Correct Answer: A
Rationale: The correct answer is A: 0.25 mL.
To calculate this, we use the formula: Volume = Amount needed / Concentration. In this case, the amount needed is 5 mg and the concentration is 20 mg/mL. So, Volume = 5 mg / 20 mg/mL = 0.25 mL.
Therefore, the nurse should administer 0.25 mL of haloperidol.
Choice B and other options are incorrect because they do not follow the correct calculation. It is important to remember to always divide the amount needed by the concentration to determine the correct volume to administer.
