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.

Explanation
A decrease in the level of consciousness is a serious sign and could be an indication of worsening conditions. It is essential for the nurse to ensure that the patient's airway is open and clear, as a compromised airway can lead to hypoxia and a further decrease in consciousness. Therefore, maintaining a patent airway should be the nurse's priority action in this situation.
While monitoring blood pressure and restricting oral intake may be important interventions in certain situations, they are not the priority actions in this scenario. Administering SQ insulin may not be necessary for a patient with hypothyroidism and acute appendicitis.
Correct Answer is A
Explanation
The most helpful finding by the nurse in determining whether a 67-yr-old patient with benign prostatic hyperplasia has an upper urinary tract infection (pyelonephritis) would be
**costovertebral tenderness**⁴. This is because costovertebral tenderness is a common symptom of pyelonephritis⁵. Pyelonephritis is an infection of the upper urinary tract that can cause fever, chills, flank pain, nausea, vomiting, and costovertebral tenderness⁵. Foul-smelling urine and bladder distention are not specific symptoms of pyelonephritis⁵. Suprapubic discomfort can be a symptom of lower urinary tract infection⁵.
