CCAT CCAT Nutrition, Weight Management and Wellness 5 — Questions and Answers
Question 1: A rehabilitation therapist is monitoring a post-TPLO dog's weight loss progress. The dog has lost 1.5% of body weight per week for four weeks. How should the therapist interpret this rate?
- Too slow — increase caloric restriction by 30%
- Appropriate — target rate is 1–2% per week for dogs (Correct answer)
- Too fast — reduce caloric restriction to prevent muscle loss
- Too fast — weight loss should not exceed 0.5% per week in orthopedic patients
Correct answer: Appropriate — target rate is 1–2% per week for dogs
A weight loss rate of 1–2% of body weight per week is considered safe and effective for dogs, balancing fat reduction with preservation of lean muscle mass.
Question 2: Which dietary component is MOST important for supporting cartilage matrix synthesis in a dog undergoing rehabilitation for hip dysplasia?
- Soluble fiber
- Sulfur-containing amino acids and glucosamine precursors (Correct answer)
- Medium-chain triglycerides
- Water-soluble B vitamins
Correct answer: Sulfur-containing amino acids and glucosamine precursors
Sulfur-containing amino acids (methionine, cysteine) and glucosamine precursors provide substrates for glycosaminoglycan synthesis, which is essential for cartilage matrix maintenance and repair.
Question 3: A feline rehabilitation patient has a muscle condition score (MCS) of 1/3. Which nutritional intervention should be PRIORITIZED?
- Caloric restriction to achieve ideal body weight before addressing muscle mass
- High-protein diet providing at least 6–8 g protein/kg body weight/day (Correct answer)
- High-fat diet to maximize energy density
- Phosphorus-restricted diet to protect renal function
Correct answer: High-protein diet providing at least 6–8 g protein/kg body weight/day
An MCS of 1/3 indicates severe muscle wasting; cats require high dietary protein (≥6–8 g/kg/day) to rebuild lean tissue, as they have uniquely high obligate protein requirements compared to dogs.
Question 4: Which hydration assessment finding is MOST consistent with mild dehydration (5%) in a rehabilitation patient?
- Sunken eyes, rapid breathing, and altered mentation
- Slightly tacky mucous membranes and skin tent lasting 1–2 seconds (Correct answer)
- Normal mucous membranes with borderline elevated skin tent
- Profuse salivation and polyuria
Correct answer: Slightly tacky mucous membranes and skin tent lasting 1–2 seconds
Mild dehydration (~5%) presents with slightly tacky mucous membranes and a skin tent that returns to normal in 1–2 seconds, without the more severe signs seen at higher dehydration percentages.
Question 5: A rehabilitation therapist notes a patient dog's coat is dull and flaky despite receiving a complete and balanced commercial diet. Which nutritional issue should be investigated FIRST?
- Excess dietary calcium causing mineral imbalance
- Inadequate essential fatty acid intake or absorption (Correct answer)
- Vitamin B12 deficiency from poor-quality protein sources
- Excess dietary fiber reducing mineral bioavailability
Correct answer: Inadequate essential fatty acid intake or absorption
Dull, flaky coat is a classic clinical sign of essential fatty acid (linoleic acid, alpha-linolenic acid) deficiency or malabsorption, which affects skin barrier function and coat quality.
Question 6: When transitioning a rehabilitation patient to a prescription weight-management diet, the daily caloric target is typically set at what percentage of RER?
- 60–70% of RER
- 80–90% of RER (Correct answer)
- 100–110% of RER
- 120–130% of RER
Correct answer: 80–90% of RER
Weight loss diets are typically initiated at 80–90% of RER (using ideal or target body weight), which creates a caloric deficit sufficient for fat loss while minimizing risk of muscle wasting or nutrient deficiency.
Question 7: A rehabilitation clinic is developing a wellness program for senior dogs. Which combination of nutritional modifications BEST addresses the most common health challenges in geriatric canine patients?
- Increased calcium and phosphorus with reduced protein to protect kidneys
- Moderately increased high-quality protein, omega-3 fatty acids, and antioxidant supplementation (Correct answer)
- Increased simple carbohydrates to support cognitive function
- High-fat diet with reduced protein to decrease metabolic demand
Correct answer: Moderately increased high-quality protein, omega-3 fatty acids, and antioxidant supplementation
Geriatric dogs benefit from increased high-quality protein to counteract age-related muscle loss, omega-3 fatty acids for joint and cognitive support, and antioxidants to combat oxidative stress associated with aging.
