Question

For patients whose actual body weight (ABW) < or = _____% IBW, Use actual (current) body wt.

For patients whose ABW > ____% IBW, use adjusted body weight.
Give one method of calculating adjusted body weight
- For patients who are fluid overloaded (renal patients or CHF) use "______" weight for actual and then calculate adjusted if necessary. When is this weight taken for those on hemodialysis?

Answer 1

For nutritional and medicinal considerations in patients, actual body weight is used if ABW is less than or equal to a certain percentage of ideal body weight, while adjusted body weight is calculated with a specific formula for ABW above that threshold. In fluid-overloaded patients, like those with renal issues or CHF, 'dry weight' is used after hemodialysis.

Step-by-step explanation:

In the context of body weight management for patients, there are guidelines to help determine whether a clinician should use actual body weight (ABW) or adjusted body weight when assessing nutritional needs or medication dosages. If a patient's ABW is less than or equal to a specified percentage of their ideal body weight (IBW), then the actual, current body weight should be used. However, for patients whose ABW is greater than this percentage threshold of their IBW, the adjusted body weight is used to accommodate potential changes in physiology due to excess weight.

One method of calculating the adjusted body weight is to use the following formula:

• Adjusted body weight = IBW + 0.4 * (ABW - IBW)

For patients who are fluid overloaded, such as those with renal issues or congestive heart failure (CHF), it may be necessary to use dry weight. This is the weight of the patient after excess fluid has been removed, often measured post-hemodialysis. The dry weight is crucial for guiding fluid removal during hemodialysis treatments and is usually taken after a dialysis session when excess fluid is presumed to be at its lowest.
