Give Dobutamine 5.5 mcg/kg/min. The drug is available as 750 mg in 500 ml of fluid. The client weighs 220 pounds. Calculate mcg/min, mcg/hr, and ml/hr. (Include the unit of measure for each answer).
Answer and Explanation

The Correct Answer is ["22"]

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

Correct Answer is C

Explanation

A. "Exposure to sunlight will help to strengthen your eyes.": Sunlight exposure is not recommended as it can exacerbate symptoms.

B. "These are unusual symptoms. I will ask the provider for an ophthalmology referral.": These symptoms are characteristic of Graves' ophthalmopathy and do not require an immediate referral unless severe.

C. "Eye drops and dim lighting can improve your symptoms." These interventions can help alleviate discomfort associated with dryness and light sensitivity in hyperthyroidism-related eye changes (Graves' ophthalmopathy). Dim lighting reduces glare, which can be uncomfortable for clients with sensitivity to light. Eye drops can provide lubrication for dry eyes.

D. "Surgery will be necessary to correct the damage to your eyes.": Surgery is considered for severe cases or when other treatments fail, not typically as an initial intervention.

Correct Answer is C

Explanation

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.
