Nutritional Assessmt


Patients that would indicate indirect calorimetry -high level of stress-difficult to wean from mechanical ventilation-morbid obesity***not needed for ICU pts.
Obesity is defined as a BMI over 30kg/m T or F? True
Basic Oxygen Consumption is the classic measure of energy expenditure T or F? False
Energy needs are increased with obese patients T or F? False
Asthma, Emphysema and Cancer are associated with protein-energy malnutrition T or F? False
RQ is the moles of carbon dioxide expired to the moles of oxygen consumed T or F? True
The primary goals of nutritional support during mechanical ventilation are to avoid loss of lean muscle mass and to keep the muscles of breathing strong enough for weaning. T or F? True
The nutritional goals for the CF patient include maximize nutritional intake and avoid caloric dense foods. T or F? False
What is the primary purpose of nutritional assessment? To develop a nutritional care plan
Kwashiorkor -may occur in combination with marasmus-child often has a pot belly-often causes facial and lib edema
Health BMI for most adults? 18.5-24.9 kg/m
Protien-energy malnutrition may be reflected in reduced values for each of the following -transthyretin-total lympocyte count-albumin levels***NOT in red blood cell count
Which of the following blood test is most useful for day to day monitoring of the nutritional status of the patient but not normally used secondary to expense? Transtheretin
What is the recommended measurement for nitrogen balance? urinary nitrogen
What changes in lung function are associated with malnutrition? Reduced VC
cathexic protruding ribs
Associated with catabolic disease sepsis-trauma-burns
Malnutrition in patients with COPD -a high work of breathing increases caloric needs-depression is common and may reduce appetite-use of a nasal cannula may contribute to the problem
Respiratory consequences of malnutriton? -increased bacterial colonization-decreased lung clearance mechanisms--loss of diaphragmatic mass and contractility
What effect does high carbohydrate intake have on metabolism? increased CO2 production
Indications for enteral nutrition support -severe pancreatitis-persistent inability to eat orally-increased CO2 production
Reasons to use enteral feedings over parenteral. -reduced incidence of stress ulcers-enteral is safer anad cheaper-enteral route may avoid intestinal atrophy
What tube feeding method is associated with an increased risk of aspiration bolus
Why raise the head of the be during tube feedings? If reduces the risk of aspriation
Metabolism issues associated with systemic inflammatory response syndrome. -triglyceride intolerance-increased macronutrient requirement-protein catabolism
