Nursing Elites

1. The principal cation in plasma and interstitial fluid is:

• A. Sodium
• B. Potassium
• C. Calcium
• D. Magnesium

Correct answer: A

Rationale: The principal cation in plasma and interstitial fluid is sodium. Sodium plays a crucial role in maintaining fluid balance and is the primary cation in extracellular fluids like plasma and interstitial fluid. Potassium is the primary cation within cells, not in extracellular fluids, making it an incorrect choice. Calcium and magnesium are essential minerals but are not the principal cations in plasma and interstitial fluid, so they are also incorrect choices.

2. The priority nursing diagnosis for a client with major depression is:

• A. Altered nutrition
• B. Altered thought process
• C. Self care deficit
• D. Risk for injury

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.

3. What percentage of body weight as fat does a woman with a healthy body composition typically average?

• A. 5%
• B. 15%
• C. 25%
• D. 35%

Correct answer: C

Rationale: A healthy body fat percentage for women typically ranges between 21% and 33%, with 25% being an average healthy body fat percentage. Choice A (5%) is too low for a healthy body fat percentage and is more in line with essential body fat levels. Choice B (15%) is also lower than the typical range for a healthy body fat percentage. Choice D (35%) is too high and would be considered high body fat for women.

4. A dietitian tells you that you are not consuming enough calories. Which of the following nutrients could you add to your diet to increase your energy intake?

• A. fiber
• B. water
• C. protein
• D. vitamins

Correct answer: C

Rationale: Corrected Rationale: Protein provides 4 kcal per gram, making it a good source of energy to increase caloric intake. While fiber and water are important for other aspects of health, they do not provide energy like protein does. Vitamins are essential for various bodily functions but do not contribute directly to caloric intake.

5. A nurse is teaching a client about strategies to prevent constipation. Which of the following statements by the client indicates an understanding of the teaching?

• A. Drinking four to five glasses of water per day will prevent constipation.
• B. I should consume mineral oil once per day.
• C. Eating foods high in fiber will make elimination easier.
• D. I can skip a meal if I feel bloated.

Correct answer: C

Rationale: The correct answer is C. Eating foods high in fiber increases stool bulk and promotes easier elimination, thus preventing constipation. Choices A, B, and D are incorrect. Drinking water is important, but the emphasis should be on high-fiber foods. Mineral oil is not a recommended first-line treatment for constipation, and skipping meals can disrupt regular bowel movements, potentially leading to constipation.
