Nursing Elites

1. 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.

2. Which medical problem is not generally associated with malnutrition?

• A. incontinence
• B. pressure sores
• C. celiac disease
• D. major surgery

Correct answer: A

Rationale: Incontinence is not typically associated with malnutrition, whereas conditions like pressure sores and celiac disease are directly linked to nutritional deficiencies and malabsorption.

3. Aling Maria is nearing menopause. She is habitually taking cola and coffee for the past 20 years. You should tell Aling Maria to avoid taking caffeinated beverages because:

• A. It is stimulating
• B. It will cause nervousness and insomnia
• C. It will contribute to additional bone demineralization
• D. It will cause tachycardia and arrhythmias

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.

4. Which of the following nutrients deficiency may lead to a diabetes-like condition?

• A. chromium
• B. iron
• C. molybdenum
• D. selenium

Correct answer: A

Rationale: Chromium is essential for proper glucose metabolism. A deficiency in chromium can result in insulin resistance, which shares similarities with diabetes. Iron, molybdenum, and selenium deficiencies do not directly lead to a diabetes-like condition. Iron deficiency causes anemia, molybdenum deficiency is rare and can lead to specific metabolic issues, and selenium deficiency may result in thyroid problems but not a diabetes-like condition.

5. A client with nephropathy secondary to diabetes mellitus is receiving dietary teaching from a nurse and plans to make dietary adjustments. Which of the following instructions should the nurse include?

• A. Consume less than 45% of total calories from carbohydrates per day.
• B. Eat no more than 300 mg of cholesterol per day.
• C. Consume less than 0.8 g/kg of body weight of protein per day.
• D. Eat at least 45 g of fiber per day.

Correct answer: D

Rationale: For a client with nephropathy secondary to diabetes mellitus, increasing fiber intake is essential as it can help manage blood sugar levels and improve overall bowel health. Choice A is incorrect because carbohydrates should be controlled but not limited to less than 45% of total calories. Choice B is incorrect as the recommended daily cholesterol intake for individuals with diabetes is less than 200 mg. Choice C is incorrect as protein intake should be individualized based on the client's condition and should not be limited to less than 0.8 g/kg of body weight per day.
