Dopamine 3 mcg/kg/min. The client weighs 176 pounds. The drug is available as 500 mg in 250 mL. Round your answer.
Answer and Explanation

The Correct Answer is ["7.2"]

Step-by-Step Calculation:

 

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

176 lbs ÷ 2.2 = 80 kg

Result = 80 kg

 

Step 2: Calculate the total dose of dopamine in mcg/min.

3 mcg/kg/min × 80 kg = 240 mcg/min

Result = 240 mcg/min

 

Step 3: Convert the total dose from mcg/min to mg/min.

240 mcg/min ÷ 1000 = 0.24 mg/min

Result = 0.24 mg/min

 

Step 4: Determine the concentration of dopamine in mg/mL.

500 mg ÷ 250 mL = 2 mg/mL

Result = 2 mg/mL

 

Step 5: Calculate the infusion rate in mL/min.

0.24 mg/min ÷ 2 mg/mL = 0.12 mL/min

Result = 0.12 mL/min

 

Step 6: Convert the infusion rate to mL/hr.

0.12 mL/min × 60 min/hr = 7.2 mL/hr

Result = 7.2 mL/hr

 

Final Result:

The IV pump should be set to 7.2 mL/hr.

Correct Answer is ["20.46"]

Explanation

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

150 pounds ÷ 2.2 = 68.18 kg

Result at each step = 68.18 kg

Step 2: Calculate the dose in mcg/min.

3 mcg/kg/min × 68.18 kg = 204.54 mcg/min

Result at each step = 204.54 mcg/min

Step 3: Convert the dose from mcg to mg.

204.54 mcg ÷ 1000 = 0.20454 mg/min

Result at each step = 0.20454 mg/min

Step 4: Calculate the infusion rate in mL/min.

0.20454 mg/min ÷ 600 mg × 1000 mL = 0.341 mL/min

Result at each step = 0.341 mL/min

Step 5: Convert the infusion rate to mL/hour.

0.341 mL/min × 60 min/hour = 20.46 mL/hour

Result at each step = 20.46 mL/hour

So, the infusion rate is 20.46 mL/hour.

Correct Answer is D

Explanation

Choice A Reason:
Pneumonia is an infection of the lungs, not the ear. It primarily affects the alveoli, causing symptoms like cough, fever, and difficulty breathing. While respiratory infections can sometimes lead to ear infections, pneumonia itself does not directly infect the ear.

Choice B Reason:
Endocarditis is an infection of the inner lining of the heart chambers and valves. It is typically caused by bacteria entering the bloodstream and does not affect the ear. Symptoms include fever, heart murmurs, and fatigue.

Choice C Reason:
Myocarditis is an inflammation of the heart muscle, usually caused by viral infections. It affects the heart's ability to pump blood and does not involve the ear. Symptoms can include chest pain, fatigue, and shortness of breath.
