What lab is the best indicator of nutritional status?

Serum proteins (albumin, transferrin, prealbumin, retinol-binding protein) are perhaps the most widely used laboratory measures of nutritional status. They are hepatically produced negative acute-phase reactants with reduced levels during systemic inflammation.

What is the best indicator of the client’s nutritional status?

Serum albumin (assessment of serum albumin is the best indicator of a client in need of total parenteral nutrition TPN) Clients whose levels are 2.5 g/dL or less are at severe risk for malnutrition.

Conclusion. After 36 hours of TPN, we recommend decreasing testing to twice a day (AM serum glucose and CBG 12 hours later) in patients without preexisting diabetes and those stable medically.

How do nutritional requirements vary between groups?

Small children have a higher basal metabolic rate than older people so need more nutrients. Children have huge energy requirements so need more calories than older people. Children need more water because they are at greater risk of dehydration. Older people might have physical problems which make eating difficult.

Can nutrients alter the absorption of other nutrients?

The absorption rate of some nutrients can be enhanced when paired with other nutrients. For instance, iron that is found in plant sources is less bioavailable than iron found in animal sources.

How age affects energy requirements?

Age. Children and adolescents need more energy for growth and development in comparison to adults. As individuals grow older, their energy requirements reduce as their body composition changes leading to a reduction in BMR. Many people also become less active as they get older.

When energy intake is greater than energy expenditure weight is?

A positive energy balance, in which energy intake exceeds expenditure causes weight gain, with 60–80 % of the resulting weight gain being attributable to body fat.
