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. A client is on a 2,000-calorie American Diabetes Association (ADA) diet and substitutes whole milk with skim milk. Which of the following items can the client add to the oatmeal on his breakfast tray?

A. One 1/8 teaspoon of salt
B. One ounce of raisins
C. One tablespoon of low-fat margarine
D. One teaspoon of brown sugar

Correct answer: B

Rationale: The correct answer is one ounce of raisins. Raisins are a healthy option to add to oatmeal as they provide natural sweetness without added sugars. They are a good source of fiber and essential nutrients. Option A, one 1/8 teaspoon of salt, is not necessary for flavoring oatmeal. Option C, one tablespoon of low-fat margarine, may add unnecessary fat to the meal. Option D, one teaspoon of brown sugar, adds extra sugar, which should be limited in a diabetes-friendly diet.

3. All of the following are contraindications when giving Immunization except:

A. BCG Vaccine can be given to a child with AIDS
B. BCG Vaccine can be given to a child with Hepatitis B
C. DPT can be given to a child that had convulsion 3 days after being given the first DPT dose
D. DPT can be given to a child with active convulsion or other neurological disease

Correct answer: B

Rationale: The correct answer is B. BCG vaccine can be given to a child with Hepatitis B, as there is no contraindication for this. Choice A, C, and D all present contraindications for administering immunizations. Choice A is incorrect because giving BCG vaccines to a child with AIDS is a contraindication. Choice C is incorrect as convulsions after the first DPT dose indicate a contraindication to subsequent doses. Choice D is incorrect because active convulsions or other neurological diseases are contraindications to receiving the DPT vaccine.

4. The RDA for iron is higher in premenopausal women than for men or postmenopausal women because of the blood loss during menstruation.

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: Both the statement and the reason are correct and related. The Institute of Medicine (IOM) recommends 18 mg of iron per day for women 19 to 50 years old, 8 mg/day for women 51 years old and older, and men 19 years old and older. During menstruation, women lose blood containing iron, leading to a higher iron requirement in premenopausal women compared to men or postmenopausal women. This increased demand aims to replenish the iron lost during this physiological process. Therefore, the statement and reason are directly linked, explaining why the RDA for iron is higher in premenopausal women than in men or postmenopausal women. Choices B, C, and D are incorrect as they do not accurately assess the relationship between the statement and the reason provided in the question.

5. Gina, A client in prolong labor said she cannot go on anymore. The health care team decided that both the child and the mother cannot anymore endure the process. The baby is premature and has a little chance of surviving. Caesarian section is not possible because Gina already lost enough blood during labor and additional losses would tend to be fatal. The husband decided that Gina should survive and gave his consent to terminate the fetus. The principle that will be used by the health care team is:

A. Beneficence
B. Non malfeasance
C. Justice
D. Double effect

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.
