Nursing Elites

1. Milk and other dairy products are preferred sources of calcium because lactose enhances calcium absorption.

• 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. Milk and other dairy products are indeed preferred sources of calcium because they supply most of the available calcium. Additionally, lactose present in dairy products enhances calcium absorption, making them even more efficient sources of this essential mineral. The statement correctly identifies dairy products as preferred sources of calcium, and the reason explains how lactose contributes to better calcium absorption. The other choices are incorrect as they do not accurately assess the relationship between lactose, calcium absorption, and the preference for dairy products as sources of calcium.

2. What does a QRS Complex represent in an ECG reading?

• A. Atrial depolarization
• B. Ventricular repolarization
• C. Ventricular depolarization
• D. End of ventricular depolarization

Correct answer: C

Rationale: The QRS Complex in an ECG reading represents ventricular depolarization, which is the process of the heart's ventricles preparing to contract by changing the electrical charge in the cell, hence choice 'C' is the correct answer. Choice 'A' is incorrect because atrial depolarization is represented by the P wave in an ECG reading, not the QRS Complex. Choice 'B' is incorrect as ventricular repolarization is depicted by the T wave, not the QRS Complex. Finally, choice 'D' is also incorrect because the QRS Complex is not the end of ventricular depolarization, but the process itself.

3. Which statement indicates understanding of a low-fiber diet?

• A. I can cut up carrots and celery sticks for my lunch.
• B. I will eat a bran muffin for my mid-morning snack.
• C. I will have oatmeal with skim milk for my breakfast.
• D. I should choose canned peaches for my fruit serving.

Correct answer: D

Rationale: The correct answer is D because canned peaches are low in fiber compared to the other options provided. Option A contains high-fiber vegetables (carrots and celery), option B includes a bran muffin which is fiber-rich, and option C involves oatmeal which is also a good source of fiber. Therefore, choosing canned peaches aligns with a low-fiber diet.

4. What type of debridement involves proteolytic enzymes?

• A. Interventional C. Surgical
• B. Mechanical D. Chemical
• C.
• D.

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.

5. During which stage of life is it most critical to build bone mass to prevent osteoporosis?

• A. Infancy
• B. Early childhood
• C. Adolescence
• D. Young adulthood

Correct answer: C

Rationale: Adolescence is the most critical stage for building bone mass, which plays a significant role in preventing osteoporosis in later life. During adolescence, approximately 45% of adult bone mass is formed. Although bone mass can be built during infancy, early childhood, and young adulthood, it is not as significant as during adolescence, making choices A, B, and D incorrect. Therefore, focusing on adequate nutrition and physical activity during adolescence is vital for long-term bone health.
