A nurse is providing teaching to a client who has hypothyroidism and has been prescribed levothyroxine. Which of the following medication instructions would the nurse include in the teaching?
"Take this medication before a meal or several hours after a meal."
"Take this medication during your morning meal."
"Take this medication with a full glass of water or fruit juice."
"Take this medication with high-protein foods."
The Correct Answer is A
A. "Take this medication before a meal or several hours after a meal." Levothyroxine absorption can be affected by food, so it's generally recommended to take it on an empty stomach to ensure consistent absorption. Food, particularly high-fiber or calcium-rich foods, can interfere with levothyroxine absorption, hence taking it before meals or a few hours after meals helps optimize its effectiveness.
B. "Take this medication during your morning meal.": This may not ensure consistent absorption as food can still interfere with medication absorption.
C. "Take this medication with a full glass of water or fruit juice.": While water is recommended for swallowing pills, it doesn't address timing or food interactions.
D. "Take this medication with high-protein foods.": Protein content in food does not affect levothyroxine absorption directly.

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
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.
