The patient is diagnosed with syndrome of inappropriate antidiuretic hormone (SIADH). What manifestation should the nurse expect to find? Decreased body weight, Decreased urinary output, Increased plasma osmolality, Increased serum sodium levels?
Understand the Problem
The question is asking about the expected manifestations related to a patient diagnosed with the syndrome of inappropriate antidiuretic hormone (SIADH). It implies understanding the clinical effects of SIADH on body fluids and electrolytes.
Answer
Decreased urinary output.
The nurse should expect to find decreased urinary output in a patient diagnosed with SIADH.
Answer for screen readers
The nurse should expect to find decreased urinary output in a patient diagnosed with SIADH.
More Information
In SIADH, there is excessive release of antidiuretic hormone (ADH), which leads to water retention, decreased urinary output, and dilutional hyponatremia (low sodium levels in the blood). This condition usually presents with normal fluid volume (euvolemic state), not increased body weight or increased serum sodium levels.
Tips
A common mistake is expecting increased serum sodium levels or increased plasma osmolality; however, these are actually decreased due to water retention and subsequent dilution.
