Description

PG 439: Let's assume the order is for 300,000 units IM for an adult. The best concentration in this case would be 250,000 units per mL. Refer to the label and notice that to make this concentration, you will need to add 4 mL of diluent. When calculated, the client would receive 12 mL (3 mL is the maximum for a large adult muscle). Remember that the condition of the intramuscular site and the client (age and muscle mass) must be considered. Depending on the status of the client, a different dosage strength may be a better choice. Notice also that when you reconstitute the medication using 4 mL, the total volume will be 4 mL, which means you have enough for approximately two additional doses. Because this is a multiple-strength solution, the dosage strength you choose must be indicated on the vial after you reconstitute it. Since the type of diluent is not indicated on the label, other resources, such as those recommended previously, must be consulted.
