Which finding indicates to the nurse that demeclocycline is effective for a patient with a syndrome of inappropriate antidiuretic hormone (SIADH)?
Urine-specific gravity is increased.
Patient's weight is increased.
Peripheral edema is decreased.
Patient’s urinary output is increased.
The Correct Answer is D
Demeclocycline is a tetracycline antibiotic that can be used to treat SIADH, a condition characterized by excessive water retention and a decrease in urinary output. Demeclocycline blocks the action of antidiuretic hormone (ADH), which can help increase urinary output and decrease water retention in patients with SIADH. Therefore, an increase in urinary output would indicate that demeclocycline is effective in treating the patient's SIADH. Options a, b, and c are incorrect because they do not directly relate to the mechanism of action of demeclocycline in treating SIADH.

Intravenous drug use is a significant risk factor for hepatitis C transmission. The other options are not necessarily related to hepatitis C transmission.
