What are common indications for administering IV fluids?

Intravenous (IV) fluids are primarily indicated for addressing situations of dehydration and electrolyte imbalance. These conditions may arise from various factors, such as excessive fluid loss due to vomiting, diarrhea, fever, or excessive sweating. Additionally, patients who are unable to take oral fluids due to conditions like severe illness, trauma, or surgery benefit significantly from IV fluid administration to restore hydration status and maintain electrolyte balance.

The electrolyte component is critical, as imbalances can lead to serious complications in multiple body systems, including cardiovascular and neurological. Administering IV fluids allows for precise control over the type and amount of fluid and electrolytes being delivered, ensuring that patients receive the necessary support to restore homeostasis.

The other options, while relevant to different aspects of healthcare, do not directly pertain to the primary use of IV fluids. Enhancing cognitive function, preventing infections, and managing anxiety disorders are not indications that would typically warrant IV fluid administration.
