1. Each statement is true regarding oral exposure to fermentable carbohydrates, except one. Which is the exception?

• A. Longer exposure leads to an increased risk of demineralization
• B. Longer exposure increases the opportunity for remineralization
• C. The Stephan curve illustrates pH changes within plaque after rinsing with a sugar solution
• D. The critical pH at which enamel decalcification occurs is 5.5 or less

Correct answer: B

Rationale: All the statements above are accurate about oral exposure to fermentable carbohydrates, except for option B. In fact, longer exposure to these carbohydrates decreases the opportunity for remineralization. This is because the process of demineralization, in which minerals are lost from the tooth enamel, is sped up by the presence of fermentable carbohydrates. The Stephan curve (option C) is a graph that demonstrates how the pH of dental plaque changes after a sugar rinse, usually dropping (becoming more acidic), which can lead to enamel decalcification. Option D is also accurate, as a pH of 5.5 or lower is the critical point at which enamel starts to decalcify.

2. he can be expected to:

• A. Profit from vocational training with moderate supervision
• B. Live successfully in the community
• C. Perform simple tasks in closely supervised settings
• D. Acquire academic skills of 6th grade level

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

3. A healthcare professional is reviewing the laboratory findings of a client who has heart failure. Which of the following findings indicates that the client is experiencing fluid volume excess?

• A. BUN 8 mg/dL
• B. Hgb 15 g/dL
• C. Creatinine 0.8 mg/dL
• D. Sodium 140 mEq/L

Correct answer: A

Rationale: A BUN level of 8 mg/dL indicates fluid volume excess in a client with heart failure. BUN (Blood Urea Nitrogen) levels can be low in fluid overload due to hemodilution, a common occurrence in heart failure. High levels of BUN usually indicate dehydration or impaired renal function, which are not the case in fluid volume excess. Choices B, C, and D are within normal ranges and do not specifically indicate fluid volume excess.

4. Which mental health disorder can lead to the erosion of lingual enamel, enlarged parotid glands, palatal bruising, and dentinal hypersensitivity?

• A. Bulimia
• B. Anorexia nervosa
• C. Depression
• D. Schizophrenia

Correct answer: A

Rationale: The correct answer is A: Bulimia. Bulimia involves repeated episodes of binge eating followed by purging, which can lead to the erosion of lingual enamel, enlarged parotid glands, palatal bruising, and dentinal hypersensitivity. This behavior exposes the teeth to stomach acid during purging, causing damage to the enamel. Choices B, C, and D are incorrect because these conditions are not typically associated with the specific oral health issues mentioned in the question.

5. Select all that apply. Which of the following are true about protein digestion?

• A. the end products of protein digestion are amino acids
• B. protein/polypeptides are digested in the large intestine by trypsin
• C. A, D
• D. protein/polypeptides are digested in the stomach by pepsin

Correct answer: C

Rationale: Protein digestion begins in the stomach with the enzyme pepsin, which breaks down proteins into smaller polypeptides. The end products of protein digestion are amino acids.
