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.
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
