Nursing Elites

1. Proteolytic enzymes are most likely to break down which food type?

• A. Carbohydrates
• B. Proteins
• C. Fats
• D. Lipids

Correct answer: B

Rationale: Proteolytic enzymes target proteins for breakdown into amino acids. Carbohydrates are broken down by enzymes like amylase, while fats are broken down by lipase. Lipids, which include fats, are not specifically targeted by proteolytic enzymes.

2. 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.

3. A nurse is teaching a group of clients about stress. Which of the following should the nurse include in the teaching?

• A. Protein requirements decrease in times of stress.
• B. Acute stress causes an increase in metabolism.
• C. Stress causes a positive nitrogen balance in the body.
• D. Glucose is broken down more slowly during times of stress.

Correct answer: B

Rationale: The correct answer is B: Acute stress causes an increase in metabolism. During acute stress, the body's fight-or-flight response is activated, leading to an increase in metabolism to provide energy for the body to respond to the stressor. Choices A, C, and D are incorrect. Protein requirements actually increase during times of stress to support the body's needs. Stress typically leads to a negative nitrogen balance in the body, not a positive one. Glucose is broken down more rapidly, not slowly, during times of stress to provide immediate energy.

4. A common side effect of diuretic medications is _____.

• A. dry mouth
• B. urinary tract infection
• C. increased taste perception
• D. nausea

Correct answer: A

Rationale: Diuretic medications can lead to dry mouth due to increased fluid loss through urination, reducing saliva production.

5. Which enzyme is most essential for hydrolyzing large protein molecules?

• A. Gastric lipase
• B. Pepsin
• C. Mucus
• D. Intrinsic factor

Correct answer: B

Rationale: Pepsin, choice B, is the correct answer as it is a proteolytic enzyme that is essential for the breakdown of large protein molecules in the stomach. Gastric lipase, choice A, is incorrect because it primarily targets fats, not proteins, hence it is not involved in protein hydrolysis. Mucus, choice C, is incorrect as it serves to protect the stomach lining from acidic gastric juices and does not play a direct role in protein digestion. Intrinsic factor, choice D, is incorrect as it is vital for the absorption of Vitamin B12 in the small intestine and doesn't participate in the process of hydrolyzing proteins.
