1. Cyanocobalamin is a form of which vitamin?

A. Vitamin B1
B. Vitamin B2
C. Vitamin B3
D. Vitamin B12

Correct answer: D

Rationale: Cyanocobalamin is a synthetic form of Vitamin B12. Vitamin B12 is essential for various bodily functions, including red blood cell formation, neurological function, and DNA synthesis. It is not to be confused with Vitamin B1, B2, or B3, which are separate vitamins with different roles in the body.

2. 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.

3. When is infertility said to exist?

A. When a woman has no uterus
B. When a woman has no children
C. When a couple has been trying to conceive for 1 year without success
D. When a couple has desired a child for 6 months

Correct answer: C

Rationale: Infertility is defined as not being able to get pregnant despite having frequent, unprotected sex for at least a year for most couples. Therefore, the correct answer is C. A, B, and D are incorrect. While having no uterus (choice A) may result in infertility, it is not the sole determining factor. Similarly, not having children (choice B) does not automatically indicate infertility. Lastly, the time frame of 6 months (choice D) is not sufficient to determine infertility; typically, a year of trying without success is required for such a diagnosis.

4. Each statement accurately describes the physical effects of food on periodontal health, except one. Which is the exception?

A. Supragingival plaque biofilm adhesion is influenced by frequent consumption of monosaccharides
B. Supragingival plaque biofilm adhesion is influenced by frequent consumption of disaccharides
C. Poor nutrition has an adverse effect on the periodontium
D. Chewing soft, spongy foods stimulates salivary flow

Correct answer: D

Rationale: The correct answer is D. Chewing soft, spongy foods does not stimulate salivary flow; rather, firm, fibrous foods like fruits and vegetables do. Soft foods can stick to teeth, promoting plaque buildup. Choices A, B, and C are accurate: Supragingival plaque biofilm adhesion is influenced by both monosaccharides and disaccharides, while poor nutrition can indeed have adverse effects on the periodontium.

5. According to the dietary reference intakes, what percentage of your daily calorie intake should ideally come from carbohydrates?

A. 10-35%
B. 20-35%
C. 40-50%
D. 45-65%

Correct answer: D

Rationale: Carbohydrates should ideally make up 45-65% of your total daily caloric intake, according to the Dietary Reference Intakes (DRIs). This range provides the necessary energy for bodily functions and activities. Choices A, B, and C are incorrect because they fall outside the recommended range for carbohydrate intake based on the DRIs.
