What could be a consequence of a lack of calories in a client relying solely on IV fluids?

A consequence of a lack of calories in a client relying solely on IV fluids is malnutrition. When a person receives intravenous fluids without adequate caloric intake, the body does not receive the necessary nutrients and energy required for maintenance and repair of tissues, as well as for normal physiological functions. This can lead to a deficiency in essential nutrients, including carbohydrates, proteins, vitamins, and minerals, which are critical for the body to perform optimally.

Inadequate caloric intake can result in the breakdown of body tissues to meet energy needs, ultimately leading to weight loss and various metabolic imbalances. Over time, this can compromise immune function, muscle mass, and overall health.

Weight gain, increased hydration, and enhanced metabolic rate do not accurately reflect the impact of insufficient calories. While IV fluids can aid hydration, they do not provide the energy needed for metabolic processes, making the risk of malnutrition a significant concern in patients relying solely on IV therapy for nutrition.
