Study Notes
Hormones and Regulation
- Aldosterone is the hormone responsible for causing sodium and water reabsorption.
- The goal of the Renin-Angiotensin-Aldosterone System (RAAS) is to regulate blood pressure.
ADH Release
- The release of ADH (Antidiuretic Hormone) is triggered by increased osmolarity and hypovolemia.
- The non-osmotic trigger of ADH release is hypovolemia.
Fluid and Electrolyte Terms
- Dextrose is another name for glucose.
- The purpose of increasing aquaporin 2 is to increase water reabsorption in the kidneys.
- Blood volume is the fluid important for increasing blood pressure.
Hyponatremia
- Pseudohyponatremia is a type of hyponatremia caused by elevated lipids in the blood.
- The normal serum osmolality level is 285-295 mOsm/kg.
- Hypertonic hyponatremia is caused by the presence of osmotic solutes that attract water into the bloodstream.
- Electrolyte abnormality is the most common type of hyponatremia.
- Symptoms associated with moderate Hypotonic Hyponatremia include headaches, nausea, and seizures.
- The difference between acute and chronic hyponatremia is the duration of the condition, with acute being less than 48 hours and chronic being more than 48 hours.
- The brain's adaptation to Hypotonic Hyponatremia is to decrease the amount of solutes in the brain cells to match the decreased osmolality of the blood.
- The first step in treating hyponatremia is to correct the underlying cause.
- A life-threatening level of hyponatremia is less than 120 mEq/L.
- Hypovolemic hyponatremia involves greater sodium than water loss.
- Euvolemic hyponatremia is caused by the release of ADH, often due to SIADH (Syndrome of Inappropriate Antidiuretic Hormone).
- The treatment for hypovolemic hyponatremia is to administer isotonic fluids.
- Rapid correction of hyponatremia should be avoided in treatment.

Description
Test your knowledge on the Renin-Angiotensin-Aldosterone System (RAAS) and antidiuretic hormone (ADH) release triggers with this quiz. Explore how angiotensin 2 and aldosterone affect sodium/water reabsorption, and understand the goals of RAAS in increasing blood volume and pressure. Learn about the osmotic and non-osmotic triggers of ADH release and their effects on water retention.
