What is the priority intervention for a severely malnourished client due to an eating disorder?

In the context of a severely malnourished client due to an eating disorder, administering intravenous (IV) fluids is the priority intervention because it addresses the immediate physical needs of the patient. Severe malnutrition can lead to dehydration and electrolyte imbalances, which can be life-threatening. IV fluids help to restore hydration, correct electrolyte imbalances, and provide essential nutrients when oral intake is not sufficient or safe.

It's crucial to stabilize the patient's physical condition before focusing on other aspects of care, such as psychological support or nutrition education, which are important but secondary in the context of acute physical health risks. By prioritizing IV fluid administration, healthcare providers ensure that the patient receives necessary support to prevent further physiological complications and create a stable foundation for additional interventions in their recovery process.
