The nurse is reconstituting a powdered medication that is labeled, "Add 2.5 mL of normal saline to make 1 gram per mL." The client's prescription is for 500 mg of the medication. How many ml. should the nurse administer to this client? (Enter numeric value only. If rounding is required, round to the nearest tenth.)

Here's how to determine the volume (mL) the nurse should administer to the client, considering the medication reconstitution and dosage: The medication is reconstituted to a concentration of 1 gram per mL. Therefore, 500 mg (which is equivalent to 0.5 grams) of the medication would be: 0.5grams​ /1gram/mL = 0.5mL So, the nurse should administer 0.5 mL of the medication.
