Nursing Elites

1. Macronutrients include each of the following except one. Which one is the exception?

• A. Fat
• B. Polyunsaturated fatty acids
• C. Carbohydrate
• D. Protein

Correct answer: D

Rationale: Macronutrients are nutrients required by the body in large amounts to provide energy and include carbohydrates, fats, and proteins. While protein is essential for the body, it is not classified as a macronutrient. Proteins are made up of amino acids and serve various functions in the body, such as building and repairing tissues, but they are not a direct energy source like carbohydrates and fats. Therefore, protein is the exception among the listed options, making it the correct answer. Choice A, Fat, Choice B, Polyunsaturated fatty acids, and Choice C, Carbohydrate, are all examples of macronutrients that provide energy and support various bodily functions.

2. A patient tells the nurse “I am depressed to talk to you, leave me alone” Which of the following response by the nurse is most therapeutic?

• A. I’ll be back in an hour
• B. Why are you so depressed?
• C. I’ll seat with you for a moment
• D. Call me when you feel like talking to me

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 physiologic role does calcium 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: A

Rationale: The correct answer is A: 'Blood clotting, transmission of nerve impulses, muscle contraction and relaxation.' Calcium plays a crucial role in various physiological functions such as blood clotting, transmission of nerve impulses, muscle contraction and relaxation, membrane permeability, and activation of certain enzymes. Choice B is incorrect because while calcium is involved in calcium homeostasis, it is not the only role it plays in the body. Choice C is incorrect as calcium indeed has several known metabolic functions, and it is not solely for preventing caries. Choice D is also incorrect as the functions mentioned are primarily carried out by other nutrients and not specifically by calcium.

4. Which of the following body processes is not dependent upon the presence of calcium in the body fluids?

• A. blood clotting
• B. transport of oxygen in the blood
• C. muscle contractions
• D. transmission of nerve impulses

Correct answer: B

Rationale: The transport of oxygen in the blood is carried out by hemoglobin, which does not require calcium; instead, calcium is essential for blood clotting, muscle contraction, and nerve transmission.

5. 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.
