Midterm, lectures 1 and 2 Flashcards
Describe the 3 aspects of the ACVN circle of nutrition
Who is being fed
What food
How is it being fed
What is the purpose of nutritional assesment
To identify problems, which leads to optimal diet choice to help prevent disease or most appropriately manage a disease for improved patient outcomes
Describe the steps of nutritional screening evaluation
- part of your history and physical exam
- BCS
- Muscle condition score
- diet history
- feeding management
- environment
- energy in food
Muscle Condition Score
- subjective assessment of the degree of muscle loss
- early muscle loss [mild] warrants intervention
Diet history
What is fed
includes treats, table scraps, supplements
Feeding management
- How much
- How often
- How is it fed (in bow, by hand, etc)
Environment
- other animals in household
- do they have access to other pet food
- do they share bowls
Energy in food
- food amount
- amount in treats, etc.
- calculate total daily calories from diet
Extended Nutritional Assessment is optional for
- healthy dogs with demanding life-stages that may warrant closer attention to detail (extremely high or low activity, multiple pet household, gestation/lactation, growth/senior)
Extended Nutritional Assessment is indicated for
unhealthy dogs
When do you need to perform an extended evaluation?
when one or more nutrition related risk factors are detected or suspected
Extended Evaluation- animal specifics
- history of disease
- presence of disease
- current medications
- CBC for anemia status
- Serum Chemistry for organ functions
- Urinalysis (specific gravity, pH, crystals, UPC)
- T4
Nutritional assessment of the diet
- is the current food appropriate for the patient
- if not recommend a different food
- recommend appropriate treats as needed
Assess the feeding management
- is the current feeding management appropriate; if not create an appropriate feeding plan
- for obese patients this may include exercise, behavior modification, weight control medication
Feeding Plan
- amount of food
- determine energy density of food
- divide energy requirement of animal by energy density of the diet
How do you calculate the DER of an outpatient dog or cat
DER = RER * DER factor
is in kcal/day
What do you use for hospitalized patients to determine daily energy requirements?
RER = 70*(BW in kg)^0.75
