A nurse is assessing a client who has thyrotoxicosis after taking too high of a level of levothyroxine. Which of the following manifestations should the nurse expect?
Drowsiness
Dry skin
Bradycardia
Heat intolerance
The Correct Answer is D
A. Drowsiness is not a typical manifestation of thyrotoxicosis. Instead, individuals with thyrotoxicosis often experience restlessness and anxiety due to excessive thyroid hormone levels.
B. Dry skin is more commonly associated with hypothyroidism (insufficient thyroid hormone levels), rather than thyrotoxicosis (excessive thyroid hormone levels).
C. Bradycardia (slower than normal heart rate) is a symptom of hypothyroidism, not thyrotoxicosis. In thyrotoxicosis, tachycardia (an abnormally rapid heart rate) is a common finding.
D. Correct. Heat intolerance is a classic symptom of thyrotoxicosis. Excessive thyroid hormone levels can lead to an increased metabolic rate, making individuals more sensitive to heat.
