Free Clinical Nutritionist CCN MCQ Questions and Answers — Questions and Answers
Question 1: Bone loss brought on by age in the elderly:
- Can be prevented by cardiovascular exercise such as swimming
- Is always reversed with calcium supplementation
- May be slowed by the use of steroid drugs
- Affects both trabecular and cortical bone (Correct answer)
Correct answer: Affects both trabecular and cortical bone
Both trabecular (spongy) and cortical (hard) bone are affected by age-related bone loss in older people. Calcium supplements may delay age-related bone loss but cannot always stop it. Weight-bearing activity, such as walking, aerobics, and weight training, slows bone loss, whereas steroid usage speeds it up.
Question 2: Obese people are more likely to make mistakes when calculating their resting energy expenditure (REE) because:
- Less than 10% of the excess weight of obese individuals is metabolically active.
- Using ideal body weight to calculate REE may overestimate the energy needed to move excess weight.
- Adipose tissue is not as metabolically active as lean body mass. (Correct answer)
- Obese people burn more calories than lean individuals.
Correct answer: Adipose tissue is not as metabolically active as lean body mass.
Because adipose tissue is not as metabolically active as lean body mass, it is difficult to accurately calculate the resting energy expenditure (REE) of obese people. The energy required to move extra body weight may be underestimated by comparing it to the optimal body weight, and roughly 25% of the extra weight of obese people is thought to be metabolically active.
Question 3: What aspect(s) of tropical sprue differs from celiac sprue?
- Tropical sprue is usually caused by bacterial contamination. (Correct answer)
- Tropical sprue cause more damage to the intestinal villi.
- None of the Above
- Tropical sprue is successfully treated with antibiotics, folate, and intramuscular vitamin B12. (Correct answer)
Correct answer: Tropical sprue is usually caused by bacterial contamination.
In contrast to celiac sprue, tropical sprue is brought on by bacterial infection, typically due to ingesting tainted vegetables or drinking polluted water. Antibiotics, folic acid, and intramuscular B12 supplements are effective treatments. Tropical sprue, a chronic, progressive illness brought on by dietary gluten intolerance, is less harmful to the intestine's villi than celiac sprue.
Question 4: What happens to food carbs when they are cooked?
- None of the Above
- Helps soften cellulose (Correct answer)
- Makes starch less digestible
- Breaks disaccharides down into monosaccharides (Correct answer)
Correct answer: Helps soften cellulose
In addition to softening cellulose, a form of dietary fiber present in fruits and vegetables, cooking food may also cause disaccharides (sugars) to break down into their monosaccharide constituents (simple sugars). Cooking makes starch easier to digest.
Question 5: The colorant that gives tomatoes their vivid red hue is:
- Lutein
- Limonene
- Anthocyanin
- Lycopene (Correct answer)
Correct answer: Lycopene
Lycopene, a carotenoid pigment, is what gives tomatoes their vivid red color. Citrus fruits include the flavonoid limonene, blue fruits and vegetables contain the pigment anthocyanin, and egg yolks contain the antioxidant lutein.
Question 6: When receiving therapy for a hiatal hernia, peppermint, chocolate, and caffeine should be avoided because:
- These foods decrease esophageal sphincter pressure. (Correct answer)
- These foods increase esophageal sphincter pressure.
- These foods stimulate the gallbladder to release bile.
- These foods cause gastric distension.
Correct answer: These foods decrease esophageal sphincter pressure.
In order to prevent reflux and irritation of the esophageal mucosa throughout the course of hiatal hernia therapy, peppermint, chocolate, and caffeine should not be consumed. The mucosa may become permanently damaged if the esophageal sphincter pressure is continuously lowered.
Question 7: All of the following are used to treat the oliguric phase of acute renal failure, with the exception of:
- 50-60 kcal/kg body weight per day
- 20-40 mEq sodium per day
- Protein intake of less than 0.6 mg/kg per day
- Fluid restriction of less than 500 ml per day (Correct answer)
Correct answer: Fluid restriction of less than 500 ml per day
Acute renal failure's oliguric phase (lower urine output) is treated with salt intake of 20–40 mEq, protein consumption of less than 0.6 mg/kg, and caloric intake of 50–60 kcal/kg per day. Protein intake is restricted until glomerular filtration recovers to normal, sodium needs are determined on edema and urine output, and calorie demands are high to encourage healing and a positive nitrogen balance. Based on losses from diarrhea, vomiting, and pee, plus 500 ml, fluid requirements are calculated.
