Administer Dopamine 3 mcg/kg/min. The client weighs 176 pounds. The drug is available as 500 mg in 250 mL of fluid. Calculate mcg/min, mcg/hr, and mL/hr. (Do not round your answer and include unit of measure with each answer)
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

Correct Answer is B

Explanation

A. "You have had a gastrointestinal bleed.": While this can cause fatigue due to anemia, it's not directly related to sickle cell anemia.

B. "You have fewer red blood cells." Sickle cell anemia causes chronic hemolysis, leading to anemia and fatigue. The characteristic sickle-shaped cells are less flexible and prone to hemolysis, resulting in fewer functional red blood cells and reduced oxygen-carrying capacity.

C. "You have an autoimmune disease.": Sickle cell anemia is not an autoimmune disorder.

D. "You have a low ferritin level.": Ferritin levels may be affected, but the primary cause of fatigue in sickle cell anemia is anemia itself, not low ferritin.
