Administer a continuous Dopamine infusion at 3 mcg/kg/min. The drug is available as 600 mg in 1000 ml of fluid. The client's weight is 110 pounds. Calculate mcg/min, mcg/hr, and ml/hr. (Include unit of measure with each answer)
Answer and Explanation

The Correct Answer is ["0.25"]

Dopamine infusion calculation based on weight and concentration.

  • Dopamine dose ordered: 3 mcg/kg/min
  • Dopamine concentration: 600 mg in 1000 mL (or 600 mcg/mL)
  • Client's weight: 110 pounds (converted to kg: 110 lbs / 2.2 = 50 kg)

Calculations:

  • mcg/min = 3 mcg/kg/min × 50 kg = 150 mcg/min
  • mcg/hr = 150 mcg/min × 60 min/hr = 9000 mcg/hr
  • mL/hr = 150 mcg/min / 600 mcg/mL = 0.25 mL/hr

Answers:

  • mcg/min = 150 mcg/min
  • mcg/hr = 9000 mcg/hr
  • mL/hr = 0.25 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.

Correct Answer is C

Explanation

A. Systemic lupus erythematosus (SLE): SLE is an autoimmune disease but is not directly linked to the pathophysiology of HIT.

B. Placental abruption: Placental abruption is a complication of pregnancy and is not a risk factor for HIT.

C. Heparin therapy for deep-vein thrombosis (DVT): Correct Answer. Heparin therapy itself, especially in the treatment of deep-vein thrombosis, is a significant risk factor for developing HIT due to the exposure to heparin.

D. Warfarin therapy for atrial fibrillation: Warfarin is not associated with the development of HIT.
