Dudek Nutrition Essentials for Nursing Practice 2026 Updated 2026 | Accurate and Verified What role do nurses play in nutritional care? - answer - - screen hospitalized patients to identify those at nutritional risk - serve as a liaison between dietitian and physician - available as a nutrition resource when dietitians are not - reinforce nutrition counseling provided by the dietitian - basic nutrition education Nutrition screening - answer - - a quick look at a few variables to identify individuals who are malnourished or who are at risk for malnutrition so that an in-depth analysis can follow - can be custom designed for a particular population or a specific disorder - no universally agreed upon tool that is valid and reliable at identifying risk of malnutrition in all populations at all times Role of the Joint Commission (JCAHO) - answer - - sets health-care standards and accredits health-care facilities that meet those standards - specifies that nutrition screening be conducted within 24 hours after admission - allows facilities to determine screening criteria, how risk is defined, and who performs the screening Malnutrition - answer - - "bad nutrition" or any nutritional imbalance including overnutrition - in practice, usually means undernutrition or inadequate intake of protein and/or calories that causes loss of fat stores and/or muscle wasting Nutrition Screen - Acute Care - answer - Common parameters in hospital setting: - dementia? - difficulty swallowing? - advanced age? (80+ years) - abnormal BMI? - nausea/vomiting? - decreased appetite? Nutritional Assessment - answer - - an in-depth analysis of a person's nutritional status (by dietitian) - in the clinical setting, nutritional assessments focus on *moderate- to high-risk* patients with suspected or confirmed protein-energy malnutrition - patients who are identified to be a low or no nutritional risk are re-screened within a specified period of time to determine if status has changed - referred to as the nutrition care process = 4 steps (ADIME): Assessment Diagnosis Intervention Monitoring/ Evaluating ABCD of an Assessment - answer - *A*nthropometric data *B*iochemical data *C*linical data *D*ietary data Anthropemetric data - answer - - physical measurements - BMI (body mass index) = formula: wt.(kg) / ht.(m)^2 ***1 kg = 2.2 lb. and 1 in. = 2.54 cm*** = healthy: 18.5 -24.9 = underweight: 18.5 = overweight: 25 - 29.9 = obese: 30 - IBW (ideal body weight) = Females: 100 lb. + 5 lb.(x), for every inch over 5 ft. = Males: 106 lb. + 6 lb.(x), for every inch over 5 ft - % change in wt. = unintentional = formula: ((usual body wt. - current body wt.) / (usual)) x 100 - Estimating calorie and protein needs Anthropometric Data: What skews weight measurements? - answer - - hydration status = dehydration (lose fluid weight) - edema - anasarca - fluid resuscitation - chronic liver or renal disease - congestive heart failure (excess weight) Anthropometric Data: Pros & Cons - answer - Pros: - easy measurements Cons: - not always properly measured - BMI does not take muscle mass into account - Can still be malnourished Body Mass Index (BMI) - answer - - an index of a person's weight in relation to height used to estimate relative risk of health problems related to weight - quick and easy to measure ht. and wt. - requires little skill - actual measures, not estimates, should be used whenever possible to ensure accuracy and reliability = a patient's stated ht. and wt. should only be used when there are no other options Weight Change - answer - - usually, weight changes are more reflective of chronic, not acute, changes in nutritional status - "significant" unintentional weight loss: --- 1 week: 2% loss of body weight --- 1month: 5% --- 3 months 7.5% --- 6 months 10 % Estimating Calorie and Protein Needs - answer - - convert body weight from lb to kg - multiple weight (kg) by: = 30 cal/kg for most healthy adults = 25 cal/kg
