1. Which mineral is a principal component of cell membranes?

• A. phosphorus
• B. magnesium
• C. iron
• D. iodine

Correct answer: A

Rationale: Phosphorus is the correct answer. It is a key component of cell membranes, being part of the phospholipid bilayer that provides structure and controls the movement of substances in and out of cells. Magnesium, iron, and iodine do not serve as principal components of cell membranes. Magnesium is involved in various enzymatic reactions, iron is essential for oxygen transport, and iodine plays a role in thyroid hormone synthesis.

2. A nurse is providing nutritional education to a client who is obese. The nurse should include in the information that which of the following gastrointestinal disorders is commonly associated with obesity?

• A. Peptic ulcer disease
• B. Gastroesophageal reflux disease
• C. Celiac disease
• D. Crohn’s disease

Correct answer: B

Rationale: Gastroesophageal reflux disease (GERD) is commonly associated with obesity due to increased abdominal pressure and other factors. Peptic ulcer disease (Choice A) is not commonly associated with obesity. Celiac disease (Choice C) is an autoimmune disorder triggered by gluten consumption and is not directly linked to obesity. Crohn’s disease (Choice D) is a type of inflammatory bowel disease and is not specifically associated with obesity.

3. A client taking antibiotics develops diarrhea. Which of the following foods should the nurse recommend to include in the client’s diet?

• A. Whole wheat bread
• B. Fresh orange sections
• C. Ice cream
• D. Yogurt

Correct answer: D

Rationale: Yogurt is the correct answer because it contains probiotics that can help restore normal gut flora and reduce antibiotic-associated diarrhea. Whole wheat bread (Choice A) may worsen diarrhea due to its high fiber content. Fresh orange sections (Choice B) are acidic and may irritate the digestive system further. Ice cream (Choice C) is high in sugar and fat, which can exacerbate diarrhea.

4. Match the energy-yielding nutrient to the amount of energy it provides to the body: Carbs, Fats, Proteins.

• A. Carbs - 4kcal/g
• B. Fats - 9kcal/g
• C. Proteins - 4kcal/g
• D. All of the above

Correct answer: D

Rationale: The correct answer is D, All of the above. Carbohydrates and proteins provide 4 kcal per gram, while fats provide 9 kcal per gram. Therefore, all three energy-yielding nutrients provide different amounts of energy to the body. Choice A, B, and C are incorrect because each of them individually provides a specific amount of energy per gram, but when considering all nutrients together, they collectively cover the spectrum of energy provision to the body.

5. A client who 1) _____ diet requires 2) ___ amounts of vitamin C.

• A. A) Follows a vegan diet, B) More
• B. B) Smokes cigarettes, B) More
• C. A) Follows a vegan diet, C) The same
• D. B) Smokes cigarettes, C) The same

Correct answer: B

Rationale: The correct answer is B) Smokes cigarettes, More. Smoking increases the need for vitamin C as it can deplete the body's vitamin C levels. Vegan diets, on the other hand, require more vitamin C for optimal absorption due to the absence of heme iron, which enhances non-heme iron absorption. Choices A and C are incorrect because vegan diets require more vitamin C, while smoking increases the need for vitamin C.
