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. A nurse is caring for an 8-month-old infant who screams when the parent leaves the room. The parent begins to cry and says, 'I don't understand why my child is so upset. I've never seen my child act this way around others before.' Which of the following statements should the nurse make?

• A. This is a normal, expected reaction for a child of this age.
• B. This is a response to an overstimulating environment.
• C. This is a common reaction to an overexposure to caregivers.
• D. This is a typical reaction for a child who is sick.

Correct answer: A

Rationale: The correct answer is 'This is a normal, expected reaction for a child of this age.' Separation anxiety typically peaks around 8-10 months of age, leading to distress when separated from caregivers. Choice B is incorrect because the infant's behavior is more likely due to separation anxiety rather than overstimulation. Choice C is incorrect as the infant's behavior is not related to overexposure to caregivers but rather a natural developmental stage. Choice D is incorrect as the infant's behavior is not indicative of illness but rather a normal emotional response.

3. You are caring for Conrad who has a brain tumor and increased Intracranial Pressure (ICP). Which intervention should you include in your plan to reduce ICP?

• A. Administer bowel softener
• B. Position Conrad with his head turned toward the side of the tumor
• C. Provide sensory stimulation
• D. Encourage coughing and deep breathing

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.

4. What physiologic role does magnesium play in the body?

• A. Blood clotting, transmission of nerve impulses, muscle contraction and relaxation
• B. Calcium homeostasis, structural integrity of heart muscle
• C. No known metabolic function, caries-preventing properties
• D. ATP energy release; metabolism of fats, carbohydrates, proteins; regulates acid-base balance

Correct answer: B

Rationale: The correct answer is B. Magnesium plays an important role in maintaining calcium homeostasis and preventing skeletal abnormalities. It is involved in more than 300 enzymatic reactions, including energy metabolism, insulin activity, and glucose use. Magnesium is vital to the structural integrity of heart muscle and other muscles and nerves. While magnesium does play a role in blood clotting, nerve impulses, muscle contraction, relaxation, ATP energy release, and metabolism of fats, carbohydrates, proteins, the primary physiologic role of magnesium in the body is related to calcium homeostasis and maintaining the structural integrity of the heart muscle. Choice A is incorrect because it includes functions of magnesium, but they are not its primary physiologic role. Choice C is incorrect as magnesium has several known metabolic functions. Choice D is incorrect because although magnesium is involved in ATP energy release and metabolism, its primary role is related to calcium homeostasis and structural integrity of muscle.

5. Which breakfast item should be recommended for a vegan adolescent to combine protein?

• A. Bagel with cream cheese
• B. Wheat toast with jelly
• C. Oatmeal pancakes with peanut butter
• D. Eggs with tofu bacon

Correct answer: C

Rationale: Oatmeal pancakes with peanut butter provide a protein combination suitable for a vegan diet.
