The nurse suspects that a patient has hyperthyroidism, and the laboratory data indicate that the patient's T4 and T3 hormone levels are elevated. Which of these findings would the nurse most likely find on examination?
Tachycardia
Dyspnea
Constipation
Atrophied nodular thyroid gland
The Correct Answer is A
A. Tachycardia is a common sign of hyperthyroidism, as elevated thyroid hormones increase heart rate and metabolic rate.
B. Dyspnea is not typically associated with hyperthyroidism; more commonly, hyperthyroid patients experience tachypnea (increased rate of breathing), but not necessarily dyspnea.
C. Constipation is more commonly associated with hypothyroidism, where metabolic slowing occurs.
D. Atrophied nodular thyroid gland is not typical of hyperthyroidism; a goiter (enlarged thyroid) is more commonly seen.
