Final answer:
To administer a 1.5g bolus IV, the nurse should administer 1.5 ml of the reconstituted solution with a concentration of 330 mg/ml.
Step-by-step explanation:
To determine how many ml should be administered, we need to calculate the total amount of medication in the reconstituted solution. The RN reconstituted a 1 g vial with 2.5 ml of water to yield a concentration of 330 mg/ml. To find the total amount of medication, we multiply the concentration by the desired dose: 330 mg/ml * 1.5 g = 495 mg.
Now, to find the volume that should be administered, we divide the total amount of medication by the concentration: 495 mg / 330 mg/ml = 1.5 ml.
Therefore, 1.5 ml should be administered.
