1. Any disease that produces ____ malabsorption can bring about deficiencies of vitamins A, D, E, and K.

• A. water
• B. protein
• C. fat
• D. carbs

Correct answer: C

Rationale: Vitamins A, D, E, and K are fat-soluble, meaning they require fat for absorption. Diseases that cause fat malabsorption can lead to deficiencies in these vitamins.

2. In the US, low iron intake is often associated with?

• A. low intake of fruits and vegetables
• B. pregnancy
• C. high sugar and fat intakes
• D. high protein intake

Correct answer: C

Rationale: Diets high in sugar and fat often lack essential nutrients like iron, leading to a risk of iron deficiency anemia, especially when iron-rich foods are not consumed adequately.

3. Each is a characteristic manifestation of necrotizing ulcerative gingivitis (NUG), except one. Which is the exception?

• A. Gingival erythema
• B. Necrosis of interdental papilla
• C. Marasmus
• D. Metallic taste and foul odor

Correct answer: C

Rationale: The correct answer is C: Marasmus. Marasmus is a form of severe malnutrition and is not a direct manifestation of necrotizing ulcerative gingivitis (NUG). Choices A, B, and D are all characteristic manifestations of NUG. Gingival erythema, necrosis of interdental papilla, and metallic taste with foul odor are commonly associated with NUG due to the inflammatory and necrotic nature of the condition.

4. Electrolytes create _____, which is caused by water following electrolytes within or between cells.

• A. energy
• B. active transport
• C. passive diffusion
• D. osmotic pressure

Correct answer: D

Rationale: Osmotic pressure is the force that drives water movement across cell membranes due to the presence of electrolytes, helping to balance fluid levels in the body. Choice A, 'energy,' is incorrect as electrolytes do not directly create energy. Choice B, 'active transport,' refers to the movement of molecules across a cell membrane requiring energy, not the movement of water. Choice C, 'passive diffusion,' is the process by which substances move from an area of higher concentration to lower concentration, not related to the movement of water following electrolytes.

5. Which type of immunity is demonstrated by the transfer of a mother's immunoglobulin across the placenta to protect the child?

• A. Natural active immunity
• B. Natural passive immunity
• C. Artificial active immunity
• D. Artificial passive immunity

Correct answer: B

Rationale: The immunoglobulin passed from the mother to the child through the placenta is an example of natural passive immunity, making choice B the correct answer. This transfer gives the child temporary immunity to various diseases without their immune system having to work. On the other hand, natural active immunity (Choice A) occurs when the body produces its own antibodies in response to an antigen. Artificial active immunity (Choice C) is achieved through vaccinations, where the immune system is stimulated to produce antibodies against a specific disease. Artificial passive immunity (Choice D) is a temporary immunity that involves the transfer of pre-formed antibodies from another source.
