1. Each statement is true of calcium within saliva, except one. Which is the exception?

• A. Saliva is supersaturated with calcium.
• B. Saliva is a source of calcium to mineralize an immature or demineralized enamel surface.
• C. Calcium and phosphate in saliva provide a buffering action.
• D. Calcium within saliva increases dental caries.

Correct answer: D

Rationale: The correct answer is D. Calcium within saliva does not increase dental caries; in fact, the buffering action provided by calcium and phosphate in saliva inhibits caries formation by preventing the dissolution of enamel by plaque biofilm. Choice A is correct as saliva is indeed supersaturated with calcium. Choice B is correct as saliva serves as a source of calcium to mineralize an immature or demineralized enamel surface. Choice C is correct as calcium and phosphate in saliva do provide a buffering action to protect teeth from acids.

2. The nurse is planning education about appropriate protein food choices for a client who has recently been prescribed a renal diet. Which protein food items should the nurse include in the education?

• A. Yogurt, seeds, and lentils
• B. Beef, bacon, and nuts
• C. Peanut butter, beans, and peas
• D. Poultry, eggs, and fish

Correct answer: D

Rationale: The correct answer is D: Poultry, eggs, and fish. These protein sources are high-quality proteins suitable for a renal diet as they provide essential amino acids without excessive amounts of potassium or phosphorus. Choice A, yogurt, seeds, and lentils, may be high in potassium and phosphorus, which could be restricted in a renal diet. Choice B, beef, bacon, and nuts, are also high in phosphorus and may not be ideal for a renal diet. Choice C, peanut butter, beans, and peas, are high in potassium and phosphorus, making them less suitable for a renal diet.

3. Dental hygienists are in a key position to assess and detect signs and symptoms of systemic disease because more than one third of the patients treated in a dental office frequently do not interact with a general health care provider.

• A. Both the statement and the reason are correct and related
• B. Both the statement and the reason are correct but are not related
• C. The statement is correct, but the reason is not correct
• D. The statement is not correct, but the reason is correct

Correct answer: A

Rationale: Dental hygienists often see patients more regularly than general healthcare providers, allowing them to identify systemic issues early.

4. The recommended daily fluid intake of patients maintained using hemodialysis is:

• A. 150 mL plus the volume of urinary output
• B. 500 mL plus the volume of urinary output
• C. 1000 mL plus the volume of urinary output
• D. 1500 mL plus the volume of urinary output

Correct answer: C

Rationale: The correct answer is C: 1000 mL plus the volume of urinary output. Fluid intake is typically restricted in hemodialysis patients to prevent fluid overload. The recommended daily fluid intake for these patients is 1000 mL plus any urinary output. Choice A (150 mL plus the volume of urinary output) is too low and would not provide enough fluid for these patients. Choice B (500 mL plus the volume of urinary output) is also insufficient. Choice D (1500 mL plus the volume of urinary output) is too high and may lead to fluid overload in hemodialysis patients.

5. In comparison to infants born to women of normal weight, infants born to obese women are _____.

• A. less likely to have heart defects
• B. more likely to be of very low birthweight
• C. less likely to experience a complicated birth
• D. more likely to have neural tube defects

Correct answer: D

Rationale: Infants born to obese women are more likely to have neural tube defects compared to infants born to women of normal weight. This increased risk is attributed to factors such as poor maternal nutrition and increased inflammation during pregnancy. Choice A is incorrect because infants born to obese women have a higher risk of heart defects. Choice B is incorrect as infants born to obese women are more likely to have higher birthweights. Choice C is incorrect as obese women are more likely to experience complications during birth.
