Question

Client is to receive Dopamine (Infropin) 2 mcg/. The client weighs 187 pounds. The available dose is 300 mg per 250 ml DSNS. How many milliliters should the nurse administer each hour?

a) 3.75 ml/hr
b) 2.8 ml/hr
c) 5.75 ml/hr
d) 4 ml/hr

Answer 1

To solve the calculation, first convert the patient's weight to kilograms, then calculate the ordered dose in milligrams per hour, and finally determine the volume needed. However, the solution calculated (8.5 mL/hr) does not match any of the options provided, which suggests there may be a mistake in the question.

Step-by-step explanation:

To calculate how many milliliters should be administered each hour for a Dopamine (Infropin) dose for a client who weighs 187 pounds, we can use the following information:

• The patient's weight in kilograms (since dosages are usually calculated using metric units): 187 lbs / 2.2 lbs/kg = 85 kg.
• The ordered dose in micrograms per kilogram per minute: 2 mcg/kg/min.
• The available dose: 300 mg in 250 mL D5NS.

First, convert the ordered dose to milligrams per hour:

(2 mcg/kg/min) × (85 kg) × (60 min/hr) = 10,200 mcg/hr = 10.2 mg/hr

Then determine the volume of the available solution needed to provide the required dose:

(10.2 mg) × (250 mL) / (300 mg) = 8.5 mL/hr

This solution is not listed among the given choices, implying a mistake in the initial question or a need for further clarification. It is important to ensure that all the variables and units are correct before performing the calculation. If there's an issue or typo in the question, it needs to be addressed before providing a definitive answer.
