The syndrome of inappropriate antidiuretic hormone (SIADH) is characterized by excessive release of antidiuretic hormone (ADH), which leads to water retention and dilutional hyponatremia. The following signs or symptoms would result from SIADH:
1. **Fluid retention** - True, due to the body's inability to excrete water effectively.
2. **Hypervolemia** - True, because the retention of water can lead to increased blood volume.
3. **Concentrated plasma** - False, as plasma would actually be diluted due to excess water retention and could lead to lower plasma osmolality.
4. **Thirst** - False, as patients with SIADH often do not exhibit significant thirst despite the body retaining fluids, given the dilution of serum sodium levels.
5. **Dehydration** - False, because SIADH typically leads to an excess of fluid, not dehydration.
In summary, the correct symptoms resulting from SIADH are **Fluid retention** and **Hypervolemia**.
1. **Fluid retention** - True, due to the body's inability to excrete water effectively.
2. **Hypervolemia** - True, because the retention of water can lead to increased blood volume.
3. **Concentrated plasma** - False, as plasma would actually be diluted due to excess water retention and could lead to lower plasma osmolality.
4. **Thirst** - False, as patients with SIADH often do not exhibit significant thirst despite the body retaining fluids, given the dilution of serum sodium levels.
5. **Dehydration** - False, because SIADH typically leads to an excess of fluid, not dehydration.
In summary, the correct symptoms resulting from SIADH are **Fluid retention** and **Hypervolemia**.
