The type of protein-energy malnutrition that results in edema, hypoalbuminemia, skin lesions, and fatty liver is:

  • A. cachexia.
  • B. marasmus.
  • C. kwashiorkor.
  • D. sarcopenia.
Correct Answer: C

Rationale: The correct answer is C, kwashiorkor. Kwashiorkor is a type of protein-energy malnutrition characterized by edema, hypoalbuminemia, skin lesions, and fatty liver. Edema is a key feature of kwashiorkor due to hypoalbuminemia, which leads to decreased oncotic pressure. Marasmus (choice B) is a form of severe malnutrition characterized by energy deficiency without significant protein deficiency, resulting in severe wasting. Cachexia (choice A) is a syndrome characterized by weight loss, muscle atrophy, fatigue, weakness, and loss of appetite in someone who is not actively trying to lose weight. Sarcopenia (choice D) is the age-related loss of muscle mass and function.

What are oligosaccharides composed of?

  • A. 3 to 10 monosaccharide units.
  • B. large portions of partially digested starch.
  • C. nonnutritive sweeteners.
  • D. used for weight management.
Correct Answer: A

Rationale: Oligosaccharides are carbohydrates composed of 3 to 10 monosaccharide units, making choice A the correct answer. Choice B is incorrect as oligosaccharides do not contain partially digested starch. Choice C is incorrect as nonnutritive sweeteners are a different category of compounds. Choice D is incorrect as oligosaccharides are not primarily used for weight management.

How does a nursing infant receive antibodies from its mother?

  • A. Through anabolism and catabolism.
  • B. Through the absorption of antibodies.
  • C. Through the absorption of amino acids and synthesis of antibodies.
  • D. Through genetic inheritance.
Correct Answer: B

Rationale: A nursing infant receives antibodies from its mother through the absorption of antibodies present in breast milk. Choice A is incorrect as anabolism and catabolism refer to metabolic processes, not the transfer of antibodies. Choice C is incorrect as the infant does not need to synthesize antibodies but directly receives them. Choice D is incorrect because while genetic inheritance plays a role in the immune system, in this case, the direct transfer of antibodies occurs through breast milk.

Which of the following enzymes is found in pancreatic secretions?

  • A. Rennin
  • B. Pepsin
  • C. Chymotrypsin
  • D. Casein
Correct Answer: C

Rationale: Chymotrypsin is an enzyme found in pancreatic secretions that plays a role in protein digestion. Rennin is primarily found in the stomach and is involved in milk digestion. Pepsin is also a stomach enzyme that aids in protein breakdown. Casein is a protein found in milk, not an enzyme involved in pancreatic secretions. Therefore, the correct answer is Chymotrypsin.

Which phase of metabolism makes growth and repair possible?

  • A. digestion
  • B. catabolism
  • C. anabolism
  • D. ketosis
Correct Answer: C

Rationale: Anabolism is the phase of metabolism responsible for building up and repairing tissues in the body. It involves processes that require energy to synthesize complex molecules from simpler ones. Digestion (choice A) is the process of breaking down food into simpler substances for absorption. Catabolism (choice B) involves the breakdown of complex molecules into simpler ones with the release of energy. Ketosis (choice D) is a metabolic state where the body uses fat as the primary source of energy, which is not directly related to growth and repair.

Which condition may benefit from branched chain amino acids (leucine, isoleucine, and valine)?

  • A. cancer-related malnutrition
  • B. marasmus
  • C. cardiovascular disease
  • D. severe depression
Correct Answer: A

Rationale: Branched chain amino acids, such as leucine, isoleucine, and valine, are essential in preventing muscle breakdown. Therefore, they may be particularly important for a patient with cancer-related malnutrition, where maintaining muscle mass is crucial. Marasmus is a severe form of malnutrition characterized by energy deficiency, not specifically related to cancer. Cardiovascular disease and severe depression do not have a direct correlation with the need for branched chain amino acids to prevent muscle breakdown.
