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. Hyperextend the client's neck: Incorrect; this can strain the surgical site. Neck should be supported in a neutral position.

B. Instruct the client to deep breathe every 4 hr: Deep breathing exercises prevent respiratory complications and promote lung expansion postoperatively. Helps prevent atelectasis and pneumonia.

C. Place the head of the client's bed in the flat position: Incorrect; semi-Fowler's position is preferred to reduce risk of airway compromise and edema.

D. Check the client's voice every 2 hr: Monitoring voice changes helps detect recurrent laryngeal nerve injury, a complication of thyroidectomy. Changes in voice quality can indicate vocal cord paralysis or injury.
