Question

Which condition can cause an extracellular fluid volume deficit?

1) The syndrome of an inappropriate antidiuretic hormone
2) Diabetes insipidus
3) Cushing syndrome
4) Long-term use of corticosteroids

Answer 1

Several conditions can cause an extracellular fluid volume deficit, including diabetes insipidus, Cushing syndrome, and long-term use of corticosteroids.

Step-by-step explanation:

An extracellular fluid volume deficit can be caused by several conditions. One condition is Diabetes insipidus, which is characterized by the underproduction of antidiuretic hormone (ADH). When ADH is not released sufficiently, water cannot be retained by the kidneys and is lost as urine, leading to dehydration.

Another condition is Cushing syndrome. In Cushing syndrome, there is hyperactivity of the adrenal cortex, which can result in increased retention of water in the body, increased blood volume, and increased blood pressure.

Additionally, long-term use of corticosteroids can also cause an extracellular fluid volume deficit. Steroid hormones, such as cortisone, can cause the retention of sodium and water in the body, leading to increased blood volume and potentially dehydration.
