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.

C. Connective tissue disorders such as scleroderma may affect skin appearance, but they typically cause hardening rather than decreased turgor.
D. Childhood growth spurts generally do not affect skin turgor unless other conditions are present, such as dehydration or malnutrition.
Correct Answer is C
Explanation
A. Increasing capillary fragility contributes to bruising and bleeding but does not directly cause skin folding or sagging.
B. Increased sebaceous and sweat glands may affect skin texture but are not the primary cause of sagging skin.
C. Decreased collagen is the primary reason for skin sagging in aging, as collagen provides structure and elasticity to the skin. With age, collagen production decreases, leading to wrinkles and sagging.
