The nurse is caring for a client with dehydration. The client's blood pressure and blood volume have stabilized after several hours of hypotension
The nurse understands that the condition of the client has stabilized because of the body's regulation of: 1. Aldosterone.
2. Adrenalin.
3. Dopamine.
4. Thyroxine.
Aldosterone
Rationale: The adrenal gland and its hormone aldosterone stimulate the reabsorption of sodium and passive reabsorption of water, thus increasing blood pressure. Adrenaline may increase blood pressure, but in response to dehydration, aldosterone will be released by the adrenal gland to cause the kidneys to hold on to sodium and water, and will increase blood pressure and blood volume. Dopamine does not influence changes in blood volume. Thyroxine is a thyroid hormone that does not affect blood pressure and blood volume.
