The physician orders a Lidocaine drip to infuse at 2 mg/min. The drug is available as 2 gm in 500 ml of fluid. Solve for ml/hr.
Answer and Explanation

The Correct Answer is ["3"]

Lidocaine infusion calculation:

  • Lidocaine dose ordered: 2 mg/min
  • Lidocaine concentration: 2 gm in 500 mL
  • Conversion factor: 1 mg = 1000 mcg

Calculations:

  • Convert Lidocaine dose to mcg/min: 2 mg/min × 1000 mcg/mg = 2000 mcg/min
  • Lidocaine concentration is 2 gm in 500 mL, which equals 4000 mcg/mL.
  • Calculate mL/hr:
    • mL/hr = (2000 mcg/min × 60 min/hr) / 4000 mcg/mL = 3 mL/hr

Answer:

  • mL/hr: 3 mL/hr

Correct Answer is ["0.25"]

Explanation

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 D

Explanation

A. Decreased thyrotropin receptor antibodies: Graves' disease is characterized by the presence of thyrotropin receptor antibodies, so they are typically increased, not decreased.

B. Decreased free thyroxine index: Graves' disease typically results in increased levels of thyroid hormones, not decreased.

C. Decreased triiodothyronine: T3 levels may be elevated in Graves' disease due to increased thyroid hormone production.

D. Decreased thyroid-stimulating hormone (TSH): Graves' disease causes excessive thyroid hormone production, leading to suppressed TSH levels. TSH is typically low in hyperthyroidism because the thyroid gland is overactive and not being stimulated by the pituitary gland.
