A nurse is preparing to administer dopamine 5 mcg/kg/min by continuous IV infusion to a client who weighs 220 lb. Available is 400 mg of dopamine in 250 mL of 0.9% sodium chloride. The nurse should set the IV pump to deliver how many mi/hr? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["18.8"]

To calculate the rate at which the IV pump should deliver dopamine, we can follow these steps:

Step 1: Convert the weight of the client from pounds to kilograms.

220 lb ÷ 2.2 = 100 kg (rounded to the nearest whole number)

Step 2: Calculate the total dose of dopamine per minute.

5 mcg/kg/min × 100 kg = 500 mcg/min

Step 3: Convert the dose from micrograms (mcg) to milligrams (mg).

500 mcg/min ÷ 1000 = 0.5 mg/min

Step 4: Determine the infusion rate in milliliters per hour (mL/hr).

The total volume of the solution is 250 mL.

The total dose of dopamine is 400 mg.

So, the infusion rate is (0.5 mg/min ÷ 400 mg) × 250 mL = 0.3125 mL/min.

Step 5: Convert the infusion rate from mL/min to mL/hr.

0.3125 mL/min × 60 min/hr = 18.75 mL/hr (rounded to the nearest tenth).

Therefore, the nurse should set the IV pump to deliver 18.8 mL/hr (rounded to the nearest tenth).

Correct Answer is A

Explanation

When a medication error occurs, the nurse should report the incident to the nurse manager or appropriate supervisor. It is essential to follow the facility's policies and procedures for reporting and managing medication errors. Prompt reporting allows for appropriate investigation, documentation, and implementation of necessary measures to prevent future errors.

Documenting that the pharmacy sent the incorrect medication (B) is not appropriate in this situation, as it does not address the nurse's role and responsibility in the error. Reporting the incident is the primary action required.

Contacting the provider to change the client's prescription (C) is not necessary in this case, as the error was related to the medication selection during administration, not an issue with the prescription itself.

Placing the unwrapped celecoxib back into the AMDS (D) is not appropriate. Once a medication has been removed from its packaging or container, it should not be returned to the dispensing system. Additionally, since it was the wrong medication for the client, it should not be administered.

Therefore, the nurse should primarily report the incident to the nurse manager or appropriate supervisor to ensure appropriate handling of the medication error.
