Question 15 :
The healthcare provider prescribes metoclopramide 7.5 mg/mL IM every 3 hours PRN vomiting for a client who is receiving chemotherapy. The nurse prepares an injection using a 2 ml. prefilled syringe cartridge labeled, "metoclopramide 5 mg/mL." How many mL should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
Correct Answer: ["1.5 mL"]
The nurse should administer 1.5 mL of the medication. This is because 7.5 mg is the desired dose, and 5 mg/mL is the concentration of the medication. Using the same formula as before, we can solve for V by plugging in the values: V = 7.5/5 = 1.5.
