Nutritional Assessmt
RESP171
| Question | Answer |
|---|---|
| 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 |
