Correct Answer is ["11.8"]

Explanation

To calculate the dosage for Dopamine as per the physician's order, we first convert the client's weight from pounds to kilograms, knowing that 1 kg equals 2.2 lbs. The client weighs 138.6 lbs, which is approximately 62.9 kg (138.6 lbs / 2.2). Now, using the ordered dose of 2.5 mcg/kg/min, we multiply the client's weight in kg by the dose to find the mcg/min: 62.9 kg * 2.5 mcg/kg/min = 157.25 mcg/min. To find mcg/hr, we multiply this by 60 minutes: 157.25 mcg/min * 60 = 9435 mcg/hr.
Next, we need to calculate mL/hr. We have Dopamine 200 mg in 250 mL, which is 200,000 mcg in 250 mL since 1 mg equals 1000 mcg. This gives us a concentration of 800 mcg/mL (200,000 mcg / 250 mL). To find the mL/hr, we divide the mcg/hr by the concentration: 9435 mcg/hr / 800 mcg/mL = 11.8 mL/hr.
Rounding to the nearest tenth, the final dosages are:
mcg/min: 157.3 mcg/min
mcg/hr: 9435 mcg/hr
mL/hr: 11.8 mL/hr
