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. A client was rushed in the E.R showing a whitish, leathery and painless burned area on his skin. The nurse is correct in classifying this burn as:

• A. First degree burn C. Third degree burn
• B. Second degree burn D. Partial thickness burn
• 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.

3. Any disease that produces ____ malabsorption can bring about deficiencies of vitamins A, D, E, and K.

• A. water
• B. protein
• C. fat
• D. carbs

Correct answer: C

Rationale: Vitamins A, D, E, and K are fat-soluble, meaning they require fat for absorption. Diseases that cause fat malabsorption can lead to deficiencies in these vitamins.

4. Furosemide (Lasix) is a drug used to _____.

• A. activate vitamin D
• B. stimulate appetite
• C. lower cholesterol
• D. mobilize fluids

Correct answer: D

Rationale: Furosemide is a diuretic that helps mobilize fluids by increasing urine output, often used to treat conditions like edema and heart failure.

5. A healthcare professional is preparing an education program for a group of parents of adolescents. Which of the following should be included as indicators of nutritional risk among adolescents? (Select one that does not apply.)

• A. Skipping more than three meals per week
• B. Eating fast food once weekly
• C. Eating without family supervision frequently
• D. Frequently skipping breakfast

Correct answer: B

Rationale: Among the indicators of nutritional risk among adolescents, skipping meals, eating without family supervision, and frequently skipping breakfast are commonly associated with poor nutrition. However, eating fast food once weekly may not necessarily indicate a significant nutritional risk, as occasional consumption of fast food in moderation is not uncommon among adolescents. This choice is the correct answer because it does not strongly correlate with nutritional risk compared to the other options provided.
