Question

A nurse is preparing to administer metoclopramide 10mg IM. Available is metoclopramide 5mg/mL. How many mL should the nurse administer? a) 1 mL b) 2 mL c) 3 mL d) 4 mL

Answer 1

The nurse should administer 2 mL of metoclopramide. This is calculated using the formula: dose required / concentration. This gives 10mg / 5mg/mL = 2 mL.

Step-by-step explanation:

When administering medication, the key point to remember is the dose to volume ratio. In your question, it's stated that the metoclopramide is available in a concentration of 5mg/mL.

This means, for every milliliter (mL) of solution, there are 5 milligrams (mg) of metoclopramide. Now, if the nurse needs to administer a 10mg dose of metoclopramide, we can use a simple formula: dose required / concentration. Therefore, the nurse will administer 10mg / 5mg/mL = 2 mL. So, the correct answer is (b) 2 mL.
