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. By the age of three, which age-appropriate food skill can a child typically perform?

• A. Using utensils and a napkin
• B. Spearing food with a fork
• C. Measuring liquids
• D. Displaying proper table manners

Correct answer: B

Rationale: By the age of three, a child typically develops the motor skills needed to spear food with a fork. This is a critical milestone in self-feeding as it shows progress in fine motor coordination. Choice 'A' is incorrect because using utensils and a napkin properly is a skill that may take longer to develop and refine. Choice 'C' is not correct as measuring liquids requires a higher level of motor skills and understanding of quantities that a three-year-old child might not possess. Choice 'D' is also incorrect as the proper display of table manners is a complex skill that is typically learned over a longer period and involves social and cultural norms.

3. Each statement is true of calcium within saliva, except one. Which is the exception?

• A. Saliva is supersaturated with calcium.
• B. Saliva is a source of calcium to mineralize an immature or demineralized enamel surface.
• C. Calcium and phosphate in saliva provide a buffering action.
• D. Calcium within saliva increases dental caries.

Correct answer: D

Rationale: The correct answer is D. Calcium within saliva does not increase dental caries; in fact, the buffering action provided by calcium and phosphate in saliva inhibits caries formation by preventing the dissolution of enamel by plaque biofilm. Choice A is correct as saliva is indeed supersaturated with calcium. Choice B is correct as saliva serves as a source of calcium to mineralize an immature or demineralized enamel surface. Choice C is correct as calcium and phosphate in saliva do provide a buffering action to protect teeth from acids.

4. In cleaning the stoma, the nurse would use which of the following cleaning mediums?

• A. Hydrogen Peroxide, water and mild soap
• B. Providone Iodine, water and mild soap
• C. Alcohol, water and mild soap
• D. Mild soap and water

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. A client who is postpartum and has been diagnosed with iron deficiency anemia should be taught to consume which of the following dietary recommendations?

• A. Yogurt and mozzarella
• B. Spinach and beef
• C. Milk and turkey slices
• D. Fish and cottage cheese

Correct answer: C

Rationale: The correct answer is spinach and beef. Both spinach and beef are high in iron, making them excellent choices to help combat iron deficiency anemia. Yogurt, mozzarella, milk, turkey slices, fish, and cottage cheese are not as rich in iron compared to spinach and beef, so they are not the most suitable dietary recommendations for a client with iron deficiency anemia.
