Answer and Explanation

The Correct Answer is ["7.2"]

Dopamine infusion calculation:

  • Client weight: 176 pounds
  • Dopamine dose ordered: 3 mcg/kg/min
  • Dopamine concentration: 500 mg in 250 mL
  • Conversion factor: 1 mg = 1000 mcg
  • 1 kg = 2.2 pounds

Calculations:

  • Convert client weight to kg: 176 lbs / 2.2 lbs/kg = 80 kg
  • Calculate mcg/min: 3 mcg/kg/min × 80 kg = 240 mcg/min
  • Calculate mcg/hr: 240 mcg/min × 60 min/hr = 14400 mcg/hr
  • Calculate mL/hr: Dopamine concentration is 2 mg/250 mL, which equals 2000 mcg/mL.
    • mL/hr = 14400 mcg/hr / 2000 mcg/mL = 7.2 mL/hr

Answers:

  • mcg/min: 240 mcg/min
  • mcg/hr: 14400 mcg/hr
  • mL/hr: 7.2 mL/hr

A. "Appearing pleased after an aggressive or impulsive act has not been directly linked to intermittent explosive disorder.": This statement is incorrect because individuals with IED may indeed feel a sense of relief or satisfaction following an outburst.

B. "Appearing pleased after an aggressive or impulsive act can be a sense of relief rather than being happy." This response is appropriate because it acknowledges that the satisfaction or pleasure observed is more likely related to relief from tension rather than genuine happiness.
