1. In which type of shock does the patient experience a mismatch of blood flow to the cells?

• A. Distributive
• B. Cardiogenic
• C. Hypovolemic
• D. Septic

Correct answer: A

Rationale: The correct answer is A: Distributive shock. Distributive shock is characterized by a widespread increase in vascular permeability leading to a relative hypovolemia and a mismatch of blood flow to the cells. Choice B, Cardiogenic shock, is due to the heart's inability to pump effectively. Choice C, Hypovolemic shock, results from a decrease in intravascular volume. Choice D, Septic shock, is caused by a systemic response to infection.

2. Which of the following amino acids are considered indispensable?

• A. Lysine
• B. Methionine
• C. Tryptophan
• D. Valine

Correct answer: A

Rationale: The correct answer is A: Lysine. Indispensable amino acids are those that the body cannot synthesize and must be obtained from the diet. Lysine, methionine, and tryptophan are all examples of indispensable amino acids. However, the question specifically asked for 3 out of the 9 indispensable amino acids, making 'Lysine' the correct choice. Choices B, C, and D are also indispensable amino acids but are not the focus of the question.

3. What is the conversion of genetic information in RNA into a sequence of amino acids?

• A. translation
• B. transcription
• C.
• D.

Correct answer: A

Rationale: The correct answer is 'translation.' Translation is the process where the genetic information in messenger RNA (mRNA) is decoded to produce a specific sequence of amino acids, forming a protein. This process occurs at ribosomes within the cell. Option B, 'transcription,' is incorrect as transcription is the process of synthesizing mRNA from a DNA template. Options C and D are irrelevant as they are not related to the conversion of genetic information into amino acids.

4. Is it correct that eliminating sucrose from the diet leads to a significant reduction in dental caries, and that the best advice is to consume sugar in moderation and limit the frequency of sugar exposure?

• A. Both statements are true
• B. Both statements are false
• C. The first statement is true; the second is false
• D. The first statement is false; the second is true

Correct answer: D

Rationale: The first statement is incorrect because dental caries are not solely caused by sucrose. They are the result of a complex interaction of multiple factors, including the type of bacteria in the mouth, the host's diet, oral hygiene, and salivary flow. The second statement is correct as consuming sugar in moderation and limiting the frequency of sugar exposure are indeed effective strategies to prevent dental caries. Therefore, the answer is option D: The first statement is false; the second is true.

5. Bones continuously lose and gain minerals. This ongoing process is called?

• A. reorganization
• B. reorienting
• C. demineralizing
• D. remodeling

Correct answer: D

Rationale: The correct answer is D, 'remodeling.' Remodeling is the process by which bones continuously lose and gain minerals, maintaining bone strength and integrity over time. 'Reorganization' (choice A), 'reorienting' (choice B), and 'demineralizing' (choice C) do not accurately describe the process of bones continuously losing and gaining minerals.
