Complete Solutions
Serum Albumin - ANS-3.5-5.0 g/dl
visceral protein
maintains colloidal osmotic pressure
hypoalbumiemia associated with edema, surgery
levels above range likely do to dehydration
long half-life, doesn't reflect current protein intake
Serum Transferrin - ANS->200 mg/dl
visceral protein that transports iron to bone marrow for production of hemoglobin.
serum levels controlled by iron storage pool
levels rise with iron deficiency. transferrin synthesis
can be determined by TIBC= total iron binding capacity
TTHY
PAB - ANS-Transthyretin, Prealbumin
16-40 mg/dl
Is considered best visceral protein to evaluate
short half-life; detects changes in protein status quickly
during inflammation. liver synthesizes CRP at expense of PAB
RBP - ANS-Retinol-Binding Protein
3-6 mg/dl
circulates with prealbumin, shortest half-life (12 hrs)
binds and transports retinol
HCT - ANS-Hematocrit
M: 42-52% F: 35-47% preg: 33%
measures iron levels
volume of packed cells in whole blood
Hgb - ANS-Hemoglobin
M:14-17 gm/dl F: 12-15 gm/dl preg: <11
iron-containing pigment of red blood cells
erythrocytes are produced in bone marrow
Serum Ferritin - ANS-M: 12-300 ng/ml F:10-150 ng/ml
,indicates size of iron storage pool
Serum Creatinine - ANS-0.6-1.4 mg/dl
related to muscle mass, measures somatic protein
may indicate renal disease, muscle wasting
(serum creatinine + BUN = kidney fx)
CHI - ANS-Creatinine Height Index
80% normal
ratio of creatinine excreted/24 hours to height
estimates lean body mass-somatic protein
60-80% mild muscle depletion
BUN - ANS-Blood Urea Nitrogen
10-20 mg/dl
related to protein intake
indicator of renal disease
BUN: creatinine ratio normal: 10-15:1
Urinary Creatinine Clearance - ANS-115 +_ 20 ml/minute
measures GFR- glomerular filtration, renal fx
estimate includes body surface area (ht and wt)
TLC - ANS-Total Lymphocyte count
>2700 cells/cu mm
measures immunocompetency
moderate depletion 900-1800
severe depletion <900
decreased in protein-energy malnutrition
CRP - ANS-C-reactive protein
marker of acute inflammatory stress
as it declines, indicates when nutritional therapy would be beneficial
when elevated CRP decreases, PAB increases
FEP - ANS-Free erythrocyte protoporphyrin
direct measure of toxic effects of lead on heme synthesis. Increases in lead poisoning.
Lead depletes iron leading to anemia, and displaces calcium in the bone leading to zinc
deficiency
PT - ANS-Prothrombin time
11.0-12.5 seconds; 85-100% of normal
anticoagulants prolong PT
evaluates clotting adequacy; change in vitamin K intake will alter rate
True or False: Hair analysis is useful for nutritional assessment. - ANS-False
, Hair analysis is not for nutritional assessment, but is useful in measuring intake of toxic
metals
megestrol acetate - ANS-appetite stimulant
oral contraceptives - ANS-decrease folate, B6, C
loop diuretics - ANS-deplete thiamin, K, Mg, Ca, Na
thiazide diuretics - ANS-decrease K and Mg, absorb Ca
methotrexate - ANS-decrease folate
lithium carbonate - ANS-antidepressant
increased appetite, weight gain; maintain consistent Na and caffeine intake to stabilize
levels.
warfarin - ANS-anticoagulant
antagonizes vitamin K- consistent levels essential
propofol - ANS-administered in oil = 1.1 cals/cc
isoniazid - ANS-treats TB
do not take with food, interferes with vitamin D
cyclosporine - ANS-immunosuppressant
hyperlipidemia, hyperglycemia, hyperkalemia, hypertension
Elavil - ANS-antidepressant
sedative effect, weight gain
vitamin B6 and protein - ANS-decreased effectiveness of levodopa
take drug in morning with limited protein
tyramine - ANS-hypertension if taken with MAOI (monoamine oxidase inhibitor)
Incidence - ANS-number of new cases of a disease over a period of time
prevalence - ANS-total number of people with a disease during a period of time
nutrition survey - ANS-examination of a population group at a particular point of time.
considered a cross-sectional exam
determines prevalence of condition or characteristics at a specific time.
nutritional surveillance - ANS-continuous collection of data
