1. Which of the following is NOT a physiological role of proteins?

• A. Providing resistance to disease
• B. Regulating fluid balance
• C. Repairing tissue
• D. Serving as the primary source of energy

Correct answer: D

Rationale: Proteins play a diverse range of physiological roles in the body, such as providing resistance to disease, regulating fluid balance, and repairing tissues. However, they are not the primary source of energy for the body. Carbohydrates and fats typically fulfill this role. Therefore, choice D is the correct answer, as it is not a function that proteins perform. Conversely, choices A, B, and C are all physiological functions of proteins, making them incorrect responses to this particular question.

2. The mother of a drug dependent would never consider referring her son to a drug rehabilitation agency because she fears her son might just become worse while relating with other drug users. The mother’s behavior can be described as:

• A. Unhelpful
• B. Codependent
• C. Caretaking
• D. Supportive

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

3. What is a major constituent of cell membranes?

• A. cholesterol
• B. phospholipid
• C. saturated
• D. triglyceride

Correct answer: B

Rationale: Phospholipids are a major component of cell membranes, providing structural integrity and facilitating cell signaling. Cholesterol (choice A) is also present in cell membranes but in smaller amounts and plays a different role. Saturated (choice C) and triglyceride (choice D) are not major constituents of cell membranes.

4. Compared to the typical American diet, what does the DASH diet provide more of?

• A. More saturated fats
• B. Fewer whole grains
• C. More fruits and vegetables
• D. Fewer dairy products

Correct answer: C

Rationale: The correct answer is C. The DASH diet, which stands for Dietary Approaches to Stop Hypertension, emphasizes the consumption of fruits and vegetables, which are high in potassium, fiber, and antioxidants. These nutrients help lower blood pressure. Therefore, compared to the typical American diet, the DASH diet provides more fruits and vegetables. Choices A, B, and D are incorrect. The DASH diet doesn't focus on providing more saturated fats or fewer whole grains or dairy products. In fact, it encourages the consumption of whole grains and low-fat dairy products to promote a balanced and healthy diet.

5. A nurse is educating the parent of a preschool-age child about nutrition. Which is the best snack choice for the nurse to recommend to the parent?

• A. Fruit snacks
• B. Mini wheat bagel with peanut butter
• C. White toast with jelly
• D. Sports drink

Correct answer: B

Rationale: The best snack choice for a preschool-age child recommended by the nurse would be a mini wheat bagel with peanut butter. This option provides a good balance of carbohydrates, protein, and healthy fats, making it a more nutritious choice compared to the other options. Fruit snacks may contain added sugars and lack essential nutrients. White toast with jelly is high in simple carbohydrates and sugars, providing less sustained energy. Sports drinks are often high in sugar and not necessary for a preschool-age child's snack.
