1. Which mineral-containing amino acids help to form the shape of proteins?
- A. phosphorus
- B. sulfur
- C. selenium
- D. iron
Correct answer: B
Rationale: The correct answer is B: sulfur. Sulfur-containing amino acids like cysteine and methionine play a crucial role in forming disulfide bonds within proteins. These bonds are essential for the proper folding and structural stability of proteins. Phosphorus (choice A), selenium (choice C), and iron (choice D) do not directly contribute to shaping proteins through bond formation.
2. Monosaccharides are converted into glucose in the liver to provide an energy supply to the cells.
- 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: A
Rationale: Both statements are true. Monosaccharides are indeed converted into glucose in the liver. Glucose, in turn, serves as a primary energy source for cells in the body, providing the necessary fuel for various cellular functions. The liver plays a crucial role in regulating blood glucose levels by converting monosaccharides into glucose and releasing it into the bloodstream when needed. Therefore, option A is the correct choice. Options B, C, and D are incorrect because both statements are accurate in this context.
3. Each is a portion of the alimentary canal, except one. Which is the exception?
- A. Oral cavity
- B. Pharynx
- C. Larynx
- D. Esophagus
Correct answer: C
Rationale: The correct answer is C, Larynx. The larynx is part of the respiratory system, responsible for voice production and breathing. The alimentary canal is involved in the digestive process and includes structures like the oral cavity (mouth), pharynx, and esophagus. Choices A, B, and D are parts of the alimentary canal, where digestion occurs, making them incorrect answers.
4. A nurse is teaching a client about complete and incomplete proteins. Which of the following foods should the nurse include in the teaching as an incomplete protein?
- A. 4 oz chickpeas
- B. 2 poached eggs
- C. 2 oz cheddar cheese
- D. 4 oz salmon fillet
Correct answer: A
Rationale: The correct answer is A: 4 oz chickpeas. Chickpeas are considered an incomplete protein because they lack one or more essential amino acids required by the body. Incomplete proteins do not provide all essential amino acids in sufficient quantities. Choice B, 2 poached eggs, is a complete protein source because eggs contain all essential amino acids. Choice C, 2 oz cheddar cheese, is also a complete protein as it contains all essential amino acids. Choice D, 4 oz salmon fillet, is another complete protein source as fish typically provide all essential amino acids needed by the body.
5. Selective inattention is seen in which level of anxiety?
- A. Mild
- B. Moderate
- C. Severe
- D. Panic
Correct answer: D
Rationale: Selective inattention is a defense mechanism seen in panic-level anxiety. In panic anxiety, individuals may experience selective inattention, where they focus only on specific aspects and ignore others. Mild anxiety does not typically involve selective inattention as individuals can still function effectively. Moderate and severe anxiety may impair attention, but selective inattention is more characteristic of panic-level anxiety.
