Nursing Elites

1. Which of the following statements are correct?

• A. Lipids are transported in the blood as lipoproteins, which are clusters of lipids associated with proteins.
• B. In type II diabetes, the pancreas produces insulin, but cells are resistant to this signal.
• C. The glycemic index classifies foods based on their potential to raise blood glucose levels.
• D. All of the above

Correct answer: D

Rationale: Option A is correct because lipoproteins indeed transport lipids in the blood. They are complexes of lipids and proteins that transport water-insoluble lipids through the blood. Option B is correct as it accurately describes the condition of type II diabetes where the pancreas can produce insulin, but the cells are resistant to its signal, causing an ineffective regulation of blood sugar. Option C is also correct because the glycemic index is indeed a classification system for foods based on their potential to raise blood glucose levels. High glycemic index foods raise blood glucose levels faster than low glycemic index foods. Hence, all the statements are correct, making option D the correct answer.

2. Select all that apply. Which of the following oils contain high levels of unsaturated fatty acids and low levels of saturated and trans fats?

• A. vegetable oil
• B. palm oil
• C. coconut oil
• D. canola oil

Correct answer: A

Rationale: Vegetable, canola, and olive oils are high in unsaturated fats and low in saturated and trans fats, making them heart-healthy choices.

3. Toilet training occurs in the anal stage of Freud’s psychosexual development. This is equivalent to Erikson’s:

• A. Trust vs. Mistrust
• B. Autonomy vs. Shame and Doubt
• C. Initiative vs. Guilt
• D. Industry vs. Inferiority

Correct answer: A

Rationale: The correct answer is A: Trust vs. Mistrust. In Freud's psychosexual development theory, the anal stage is where toilet training occurs, focusing on issues of control and independence. This stage is parallel to Erikson's Trust vs. Mistrust stage, where infants learn to trust or mistrust their caregivers based on the consistency of care they receive. Choices B, C, and D are incorrect as they correspond to different stages in Erikson's psychosocial development theory, not related to toilet training or the anal stage of Freud's theory.

4. Earliest sign of skin reaction to radiation therapy is:

• A. desquamation
• B. erythema
• C. atrophy
• D. pigmentation

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

5. Each statement is true of vitamin K, except one. Which is the exception?

• A. Vitamin K is produced in the gut.
• B. Vitamin K functions as a catalyst for the synthesis of blood-clotting factors.
• C. Vitamin K maintains prothrombin levels.
• D. Vitamin K absorption increases with high levels of vitamin E supplementation.

Correct answer: D

Rationale: The correct answer is D. Vitamin K absorption decreases with high levels of vitamin E supplementation because in larger amounts, vitamin E acts as an anticoagulant. Vitamin K is not produced in the gut but can be obtained from food sources or supplements. Vitamin K is essential for the synthesis of blood-clotting factors and is crucial in maintaining prothrombin levels, which is vital for proper blood clotting. The incorrect choice, D, is misleading as high levels of vitamin E supplementation hinder vitamin K absorption due to its anticoagulant properties. Dental hygienists should be aware of the importance of vitamin K in blood clotting, especially when treating patients who are on anticoagulant medications for conditions like stroke prevention.
