Q

Nutrition Assessment History
Questions to Assess if:

LOSS IN SUBQ FAT

A

Loss of sub Q fat:
ORBITAL = SUNKEN EYES

Triceps

Fat Overlying Ribs

  • *Marasmus**
  • loss of SKELETAL MUSCLE + BODY FAT*
17
Q

Nutrition Assessment History
Questions to Assess if:

FLUID ACCUMULATION

A

General** or **Localized

Mild / Moderate / Severe

EDEMA = Kwashiorkor

18
Q

Nutrition Assessment History
Questions to Assess if:

LOSS IN MUSCLE MASS

A

LOSS IN TEMPLES = Sunken

Clavicles / Shoulders

Interosseous / Scapula / Calf

  • *Kwashiorkor**
  • loss in visceral PROTEINS*
19
Q

Nutrition Diagnosis
PATHWAY CHART

A

Is the patient MALNOURISHED? = 2/6 of Criteria?
VVVV
Kwashiorkor / Marasmus / or MIXED?
VVV
Determine Underlying Cause of Malnutrition
VVVV
3 groups below

DRM + Inflammation** // **DRM only** // **No Disease
DRM = Disease-Related Malnutrition

20
Q

Nutrition Diagnosis

DRM + Inflammation

A

ACUTE Disease or Injury-Related malnutrition
Major Infections / Burns
closed Head injury / SURGERY

CHRONIC DRM + inflammation
Cancer CACHEXIA + Others:
COPD / IBD / CHF / CKD
+ other END STAGE organ diseases

21
Q

Nutrition Diagnosis

DRM without inflammation

A
  • *DYSPHAGIA** due to:
  • *STROKE / Parkinsons / ALS**

ANOREXIA NERVOSA

Malabsorption Due to Intestinal Disorders

22
Q

HISTORY
Nutrition Assessment

A

Chief Complaint

Chronic Diseases
DM / Pancreatitis / Cancer / AIDS / Kidney-Liver Disease

Surgical History
Bowel resection / Liver / Pancreatic procedures

Medications
absorption altering / food-drug interactions / taste / appitite supression / nausea

Socioeconomic Factors
substance abuse

23
Q

MEDICATIONS

Nutritional Assessment HISTORY

A

CORTICOSTEROIDS
Alter glucose-fat-protein metabolism / Electrolyte disturbance / P

Protease Inhibitors
can cause HypoGlycemia

HIV Medications
Alter FAT metabolism

24
Q

LAB MEASUREMENTS
For Nutritional Assessment

A

we do NOT use Lab Values to diagnose
more of a marker for INFLAMMATION, not just malnutrition severity

Decreased synthesis of ACUTE PHASE PROTEINS
Albumin / Transferrin / PRE-ALBUMIN / retinol binding protein
used to estimate protein requirements

Increase Acute Phase Proteins
C-Reactive protein , may be useful in illness recovery period

25
Q

Anthropometrics
Nutrition Assessment

A

BOTH NOT GOOD AT DIAGNOSING FOR MALNUTRITION

  • *BMI**
  • *extremes may increase risk of malnutrition**, but not very well correlated

Actual BW vs IBW
also not well correlated, extremes may increase risk of malnutrition

26
Q

IBW Calculations

A

ADULT MEN
50kg + [2.3 x (inches over 5ft)]

ADULT WOMEN
45kg + [2.3 x (inches over 5ft)]

27
Q

Indirect Calorimetry
Other Measurements of Nutrition Assessment

A

DOES NOT WORK
only works for VENTILATED ICU PATIENTS

Assesses adequate calorie administration

Reads:
Resting Energy Expenditure = REE kca/lday
Oxygen uptake vs CO2 output
RESPIRATORY QUOTIENT** = **RQ
VCO2 / VO2

28
Q

Respiratory Quotient > 1

RQ

A

OVERFEEDING
Lipogenesis / HYPERventilation / system leak

Determined through:
Indirect Calorimetry

VCO2 / VO2
CO2 OUTPUT / Oxygen UPTAKE

Normal = 0.82 - 0.85

29
Q

Respiratory Quotient < 0.7

A

UNDERFEEDING
Primary fat oxidation / metabolic alkalosis / ethanol oxidation

Determined through:
Indirect Calorimetry

  • *VCO2 / VO2**
  • *CO2 OUTPUT / Oxygen UPTAKE**

Normal = 0.82 - 0.85

30
Q

NITROGEN BALANCE

Other Measurements of Nutrition Assessment

A

Assessed in patients in:
RECOVERY PHASE of Illness

Assessment of:
Adequate PROTEIN administraion

24 Hour collection of
URINARY UREA NITROGEN = UUN

  • *GOAL IS TO BE SLIGHTLY POSITIVE**
  • *= +1 / +2**

Negative = breaking down muscle mass
