1. Sugar alcohols have anticariogenic properties and can protect the teeth by decreasing demineralization, enhancing remineralization, or increasing salivary flow, even in the presence of a fermentable carbohydrate. Name 3 sugar alcohols.
- A. Sorbitol
- B. Mannitol
- C. Xylitol
- D. Erythritol
Correct answer: D
Rationale: Sugar alcohols such as sorbitol, mannitol, and xylitol are commonly used in sugar-free products and have properties that help protect teeth from caries by promoting remineralization and increasing salivary flow. Erythritol is another common sugar alcohol used as a sweetener in various products, but it was not listed in the question.
2. Which statement about the human immunodeficiency virus (HIV) is true?
- A. About 30 percent of all new HIV infections affect women.
- B. In South Africa, 30 percent of all pregnant women are HIV-positive.
- C. About 30 percent of new HIV infections occur in developing countries.
- D. Untreated HIV-infected mothers pass the virus to the fetus 30 percent of the time.
Correct answer: B
Rationale: The correct answer is B: 'In South Africa, 30 percent of all pregnant women are HIV-positive.' This statement is true as South Africa has a high prevalence of HIV among pregnant women, emphasizing the need for interventions to prevent mother-to-child transmission. Choices A, C, and D are incorrect. Choice A is inaccurate as women account for more than 50% of new HIV infections globally. Choice C is misleading as the majority of new HIV infections actually occur in sub-Saharan Africa, not just developing countries. Choice D is also incorrect as without treatment, the risk of mother-to-child transmission is higher than 30%.
3. A healthcare provider orders a medication dose three times higher than usual. What is the nurse's first step?
- A. Administer the medication but monitor the patient closely.
- B. Verify the dosage with the prescribing provider.
- C. Administer a lower dose to minimize the risk.
- D. Hold the medication and wait for further clarification.
Correct answer: B
Rationale: The correct answer is B: Verify the dosage with the prescribing provider. When faced with an unusual medication dose, the nurse's initial action should be to confirm the order with the healthcare provider who prescribed it. This step is crucial to prevent medication errors and ensure patient safety. Choices A, C, and D are incorrect because administering the medication without clarification, administering a lower dose without approval, or holding the medication without consulting the provider can all pose risks to the patient's well-being.
4. While reviewing the monitor tracing of a client in labor, a nurse notes late decelerations. Which of the following interventions should the nurse perform?
- A. Administer oxygen via nasal cannula
- B. Reposition the client onto her left side
- C. Administer an amnioinfusion
- D. Provide reassurance to the client
Correct answer: B
Rationale: Repositioning the client onto her left side is the appropriate intervention when late decelerations are noted on the monitor tracing. This action helps increase uteroplacental blood flow by relieving pressure on the vena cava and aorta, improving fetal oxygenation. Administering oxygen via nasal cannula may be indicated for variable decelerations, not late decelerations. Administering an amnioinfusion is not the primary intervention for late decelerations. Providing reassurance to the client is important but addressing the underlying cause of late decelerations takes precedence.
5. Each of the following is a form of vitamin K, except one. Which is the exception?
- A. Phylloquinone
- B. Tocopherol
- C. Menaquinone
- D. Menadione
Correct answer: B
Rationale: Tocopherol, Choice B, is not a form of vitamin K; it is another name for vitamin E. Phylloquinone (Choice A), menaquinone (Choice C), and menadione (Choice D) are all forms of vitamin K. Phylloquinone is vitamin K1 found in green plants, menaquinone is vitamin K2 produced in the large intestine and found in animal tissues, and menadione is a synthetic form of vitamin K. Therefore, Choice B is the correct answer because it does not belong to the vitamin K group, unlike the other options.
