A 26-year-old client is admitted to the hospital for treatment of a simple goitre, and levothyroxine sodium is prescribed. Which symptoms indicate to the nurse that the prescribed dosage is too high for this client?

Choice A reason: Lethargy and lack of appetite are symptoms that might indicate hypothyroidism or an insufficient dosage of levothyroxine. These symptoms are not typically associated with a dosage that is too high.Choice B reason: Bradycardia and constipation are also indicative of hypothyroidism or an inadequate dosage of levothyroxine. These symptoms suggest a need for a higher dosage rather than indicating that the current dosage is too high.Choice C reason: Muscle cramping and dry, flushed skin can be associated with electrolyte imbalances or dehydration, but they are not specific symptoms of an excessive dosage of levothyroxine.Choice D reason: Palpitations and shortness of breath are signs of hyperthyroidism, which can occur if the dosage of levothyroxine is too high. These symptoms indicate that the client's metabolism is excessively stimulated, leading to cardiovascular strain and respiratory distress. It is crucial for the nurse to monitor these symptoms and adjust the medication dosage accordingly.
