A patient's laboratory data reveal an elevated thyroxine (T4) level. What gland should the nurse assess?
Adrenal
Parotid
Thyroid
Parathyroid
The Correct Answer is C
A. Adrenal: The adrenal glands produce hormones like cortisol and adrenaline, but not thyroxine.
B. Parotid: The parotid glands are salivary glands and are unrelated to thyroxine production.
C. Thyroid: The thyroid gland produces thyroxine (T4), and elevated levels of this hormone indicate that the thyroid gland should be assessed for potential hyperthyroidism.
D. Parathyroid: The parathyroid glands regulate calcium levels but do not produce thyroxine.

D. Axillary nodes drain the upper limbs, including the forearm and hand, and are likely to be swollen if there is an infection in the upper extremities.
Correct Answer is A
Explanation
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.
