Nursing Elites

1. How is the equalization of solute concentration of intracellular fluids (ICFs) and extracellular fluids (ECFs accomplished?

• A. Semipermeable membranes.
• B. Hydration.
• C. Osmotic pressure.
• D. Perspiration.

Correct answer: C

Rationale: The correct answer is C, osmotic pressure. Osmotic pressure within the body equalizes the solute concentration of ICFs and ECFs by shifting small amounts of water in the direction of higher concentration solute. Semipermeable membranes separate one fluid compartment from another and do not directly equalize solute concentrations. Hydration and perspiration are important elements of fluid balance but do not directly achieve the equalization of solute concentrations between ICFs and ECFs, which is primarily regulated by osmotic pressure.

2. The nurse knows that after receiving the blood from the blood bank, it should be administered within:

• A. 1 hour
• B. 2 hours
• C. 4 hours
• D. 6 hours

Correct answer: D

Rationale: Blood transfusions need to be administered promptly after receiving the blood from the blood bank to ensure patient safety and effectiveness. Waiting too long can lead to complications such as bacterial growth in the blood product, which can be harmful when infused. Administering the blood within 6 hours is crucial to prevent such risks. Choices A, B, and C are incorrect because waiting for 1, 2, or 4 hours respectively can increase the likelihood of complications associated with delayed transfusion.

3. Persons experiencing crisis becomes passive and submissive. As a nurse, you know that the best approach in crisis intervention is to be:

• A. Active and Directive
• B. Passive friendliness
• C. Active friendliness
• D. Firm kindness

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.

4. 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.

5. Which of the following amino acids are considered indispensable?

• A. Lysine
• B. Methionine
• C. Tryptophan
• D. Valine

Correct answer: A

Rationale: The correct answer is A: Lysine. Indispensable amino acids are those that the body cannot synthesize and must be obtained from the diet. Lysine, methionine, and tryptophan are all examples of indispensable amino acids. However, the question specifically asked for 3 out of the 9 indispensable amino acids, making 'Lysine' the correct choice. Choices B, C, and D are also indispensable amino acids but are not the focus of the question.
