The nurse is caring for a client who has a diagnosis of syndrome of inappropriate antidiuretic hormone secretion (SIADH). The plan of care includes assessment of specific gravity every 4 hours. The results of this test will allow the nurse to assess what aspect of the client's health?
Nutritional Status
Potassium Balance
Calcium Balance
Fluid Volume Status
The Correct Answer is D
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.

C. Weight gain is a common symptom of untreated hypothyroidism; effective levothyroxine therapy should help normalize weight.
D. A decrease in TSH indicates that the body is receiving adequate thyroid hormone, suppressing the pituitary's signal for more, and is a primary marker of a therapeutic response to levothyroxine.
