A nurse is caring for a client who has returned to the floor after having a thyroidectomy for thyroid cancer. What laboratory finding may be an early indication of parathyroid gland injury or removal?
Hyponatremia
Hypophosphatemia
Hypocalcemia
Hypokalemia
The Correct Answer is C
A. Hyponatremia is not directly related to parathyroid function and is more commonly associated with conditions like SIADH.
B. Hypophosphatemia may be seen in refeeding syndrome or other metabolic disturbances, but not as a primary indicator of parathyroid injury.
C. Hypocalcemia is the hallmark laboratory finding following accidental removal or injury to the parathyroid glands during thyroidectomy, as parathyroid hormone (PTH) regulates calcium levels.
D. Hypokalemia is related to potassium imbalance and is not specific to parathyroid or calcium regulation.

Correct Answer is D
Explanation
A. Nutritional status is not evaluated using urine specific gravity; this requires dietary intake assessments and lab tests like albumin or prealbumin.
B. Potassium balance is monitored through serum potassium levels, not urine specific gravity.
C. Calcium balance is also assessed through blood tests, not specific gravity measurements.
D. Urine specific gravity reflects the concentration of solutes in the urine and is a direct indicator of fluid volume status. In SIADH, excessive ADH causes water retention and concentrated urine, resulting in elevated specific gravity, which helps monitor the effectiveness of fluid management.
