Nursing Elites

1. Which of the following body processes is not dependent upon the presence of calcium in the body fluids?

• A. blood clotting
• B. transport of oxygen in the blood
• C. muscle contractions
• D. transmission of nerve impulses

Correct answer: B

Rationale: The transport of oxygen in the blood is carried out by hemoglobin, which does not require calcium; instead, calcium is essential for blood clotting, muscle contraction, and nerve transmission.

2. Which step of the management process is concerned with Policy making and Stating the goals and objective of the institution?

• A. Planning
• B. Organizing
• C. Directing
• D. Controlling

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.

3. Which of the following converts starch to disaccharides, and this reaction occurs in the _____?

• A. pancreatic amylases, small intestine
• B. brush border enzymes, small intestine
• C. luminal enzymes, large intestine
• D. pancreatic amylases, pancreas

Correct answer: A

Rationale: The correct answer is A. Pancreatic amylases break down starch into disaccharides in the small intestine. This process occurs in the small intestine, not the large intestine or pancreas. Brush border enzymes act on disaccharides to break them down into monosaccharides, while luminal enzymes are not specifically involved in the conversion of starch to disaccharides.

4. The nurse understands that malnutrition is a prevalent issue among hospitalized individuals. What is it commonly associated with?

• A. Decreased health care expenses
• B. Elevated blood pressure
• C. Decreased mortality rates
• D. A compromised immune system

Correct answer: D

Rationale: Malnutrition is often associated with a weakened immune system. This is because when the body is not sufficiently nourished, it lacks the necessary nutrients to maintain a well-functioning immune system, making patients more vulnerable to infections and other health complications. This can potentially increase mortality rates and prolong hospital stays, contrary to choice C. Choices A and B are incorrect as malnutrition does not lead to decreased health care costs or high blood pressure. In fact, it may increase health care costs due to the potential for increased complications and extended hospital stays.

5. What is the most significant dietary influence on the development of dental caries?

• A. Carbohydrates
• B. Vitamins
• C. Minerals
• D. Fats

Correct answer: A

Rationale: The correct answer is A: Carbohydrates. Carbohydrates, especially fermentable sugars, are the most significant dietary factor in the development of dental caries. When these sugars are consumed, they can be fermented by bacteria in the mouth, leading to the production of acids. These acids lower the pH in the mouth, creating an acidic environment that promotes demineralization of the tooth enamel, ultimately causing dental caries. Choices B, C, and D are incorrect because while vitamins and minerals are important for overall health, they do not have the same direct impact on the development of dental caries as fermentable carbohydrates do. Fats, on the other hand, do not play a significant role in the development of dental caries.
