Anthropometry Screening Tools Flashcards
When do you need to find the adjusted BW (2 possibilities)?
- BW > 125% IBW
2. BMI > 27
How do you calculate a patient’s weight in the case of an amputation?
Establish amount of amputation and subtract that proportion from IBW
What weight (adjusted or actual) is used for HB and MSJ?
HB: adjusted
MSJ: actual
What are the fluid requirements?
If weight < 125% IBW
- 18-55y = 35 ml/kg
- 56-75y = 30 ml/kg
- > 75y = 25 ml/kg
If weight > 125% IBW
Use ADJUSTED weight
TLC values are reduced and elevated in which conditions?
Reduced: viral infection, chemotherapy, radiation, some meds, AIDS, cancer, immunosuppressive drugs
Increased: tissue necrosis and infections
What happens to pre-albumin with corticosteroids and CKD?
It increases (while the other acute phase proteins such as albumin decrease)
When is ferritin increased?
infection inflammation trauma iron overload viral hepatitis
What do high and low values of transferrin mean?
high: iron deficiency
low: PEM
How is calcium found in the body?
60% is bound to protein, mainly albumin
low albumin = low calcium
What are the 3 stages of anemia?
first: depletion of iron stores (low ferritin)
second: iron deficiency without anemia (low transferrin saturation and high erythrocyte protoporphyrin
third: iron deficiency anemia (low hemoglobin and low MCV)
What are the 2 types of hyponatremia?
- with edema: fluid restriction + sodium restriction
2. no edema (SIADH): fluid restriction
What are the criteria of the NRS2002?
- BMI < 20.5
- has the patient lost weight within the last 3 months?
- has the patient had a reduced dietary intake in the last week?
- is the patient severely ill?
Mild 1:
- weight loss > 5% in 3 months or food intake below 50-75%
- hip fracture, COPD, cirrhosis
Moderate 2:
- weight loss > 5% in 2 months or BMI 18.5-20.5
- major abdominal surgery, stroke
Severe 3:
- weight loss > 5% in 1 month or > 15% in 3 months or BMI < 18.5
- head injury, bone marrow transplantation (apache >10)
** Add a point if person is >70y
What does CBC include?
- the number of RBC, WBC and platelets
- the total amount of hemoglobin in the blood
- the fraction of the blood composed of RBC (hematocrit)
- the size of the RBD (MCV)
What are the numbers for TLC?
mild malnutrition: 1.2-1.8
moderate depletion: 0.8-1.199
severe depletion: <0.8
What are CD4 cells and what is their relationship with HIV?
They are white blood cells that fight infection
HIV virus uses CD4 cells to propagate
