A.

Enoxaparin

B.

Alteplase (tPA)

C.

Warfarin

D.

Answer and Explanation

The Correct Answer is A

A. Enoxaparin. Enoxaparin is a low molecular weight heparin used for prophylaxis against DVT. It works by inhibiting clotting factors and is commonly used postoperatively to prevent DVT formation.

B. Alteplase (tPA): Alteplase is a thrombolytic agent used to dissolve clots and is not used for DVT prophylaxis.

C. Warfarin: Warfarin requires monitoring and has a delayed onset, making it less suitable for immediate postoperative DVT prophylaxis.

D. Clopidogrel: Clopidogrel is an antiplatelet agent and is not typically used for DVT prophylaxis postoperatively.

Correct Answer is ["22"]

Explanation

Dobutamine infusion calculation:

  • Client weight: 220 pounds
  • Dobutamine dose ordered: 5.5 mcg/kg/min
  • Dobutamine concentration: 750 mg in 500 mL
  • Conversion factor: 1 mg = 1000 mcg
  • 1 kg = 2.2 pounds

Calculations:

  • Convert client weight to kg: 220 lbs / 2.2 lbs/kg = 100 kg
  • Calculate mcg/min: 5.5 mcg/kg/min × 100 kg = 550 mcg/min
  • Calculate mcg/hr: 550 mcg/min × 60 min/hr = 33000 mcg/hr
  • Calculate mL/hr: Dobutamine concentration is 750 mg/500 mL, which equals 1500 mcg/mL.
    • mL/hr = 33000 mcg/hr / 1500 mcg/mL = 22 mL/hr

Answers:

  • mcg/min: 550 mcg/min
  • mcg/hr: 33000 mcg/hr
  • mL/hr: 22 mL/hr
