CCAT CCAT Nutrition, Weight Management and Wellness 4 — Questions and Answers
Question 1: A 9-year-old obese Labrador Retriever is beginning a rehabilitation program. Which nutritional strategy best supports both weight loss and joint health simultaneously?
- High-protein, calorie-restricted diet with omega-3 fatty acid supplementation (Correct answer)
- Low-protein, high-carbohydrate diet with vitamin C supplementation
- Standard maintenance diet with reduced portion sizes only
- High-fat diet with glucosamine supplementation only
Correct answer: High-protein, calorie-restricted diet with omega-3 fatty acid supplementation
High-protein, calorie-restricted diets preserve lean muscle mass during weight loss while omega-3 fatty acids (EPA/DHA) provide anti-inflammatory benefits that support joint health in rehabilitation patients.
Question 2: When calculating a therapeutic diet's calorie content for a dog using metabolizable energy (ME), which formula is used to estimate resting energy requirement (RER)?
- RER = 30 × (body weight in kg) + 70
- RER = 70 × (body weight in kg)^0.75 (Correct answer)
- RER = 50 × (body weight in kg)^0.5
- RER = 100 × (body weight in kg) − 30
Correct answer: RER = 70 × (body weight in kg)^0.75
RER is calculated as 70 × (body weight in kg)^0.75, which accounts for the metabolic scaling relationship between body mass and energy expenditure.
Question 3: A rehabilitation patient cat is diagnosed with sarcopenic obesity. Which approach is MOST appropriate for nutritional management?
- Aggressive caloric restriction to reduce body weight as quickly as possible
- High-protein diet with moderate caloric restriction to preserve lean muscle mass (Correct answer)
- High-carbohydrate diet to provide energy for muscle synthesis
- Fat-restricted diet with unlimited feeding to encourage activity
Correct answer: High-protein diet with moderate caloric restriction to preserve lean muscle mass
Sarcopenic obesity requires a high-protein diet to preserve and rebuild lean muscle tissue while moderate caloric restriction promotes fat loss without worsening muscle wasting.
Question 4: Which body condition scoring (BCS) system component is MOST relevant when monitoring a rehabilitation patient's response to a weight management program?
- Hair coat quality and skin turgor
- Rib palpation, waist definition, and abdominal tuck (Correct answer)
- Mucous membrane color and capillary refill time
- Limb circumference and muscle symmetry only
Correct answer: Rib palpation, waist definition, and abdominal tuck
BCS assessment relies primarily on rib palpation (fat coverage), waist definition viewed from above, and abdominal tuck viewed from the side to evaluate fat stores and response to weight management.
Question 5: A client reports their post-surgical dog refused its prescribed therapeutic diet for two days. What is the MOST appropriate nutritional guidance?
- Discontinue the therapeutic diet and return to the previous food immediately
- Transition gradually by mixing the therapeutic diet with the previous food over 7–10 days (Correct answer)
- Force-feed the therapeutic diet to ensure adequate nutrition
- Skip meals for 24 hours to increase hunger before reintroducing the diet
Correct answer: Transition gradually by mixing the therapeutic diet with the previous food over 7–10 days
A gradual transition over 7–10 days by mixing increasing amounts of the new diet with the previous food reduces gastrointestinal upset and improves acceptance of therapeutic diets.
Question 6: Which micronutrient deficiency is MOST likely to impair wound healing and collagen synthesis in a post-surgical rehabilitation patient on a calorie-restricted diet?
- Vitamin A
- Vitamin C (Correct answer)
- Vitamin D
- Vitamin K
Correct answer: Vitamin C
Vitamin C (ascorbic acid) is essential for collagen hydroxylation and cross-linking; deficiency directly impairs wound healing and connective tissue repair in rehabilitation patients.
Question 7: In canine rehabilitation patients, which condition warrants the MOST caution when recommending fish oil (omega-3) supplementation?
- Osteoarthritis with mild joint effusion
- Obesity with concurrent hyperlipidemia (Correct answer)
- Post-surgical soft tissue recovery
- Age-related muscle atrophy in geriatric patients
Correct answer: Obesity with concurrent hyperlipidemia
Fish oil supplementation can elevate triglyceride levels and worsen hyperlipidemia in susceptible patients, requiring careful monitoring and possible dose adjustment before recommending it.
