Nursing Elites

1. _____ neutralizes stomach acid in the small intestine:

• A. saliva
• B. gastric mucus
• C. bicarbonate ions
• D. enzymes

Correct answer: C

Rationale: The correct answer is C: bicarbonate ions. Bicarbonate ions, secreted by the pancreas, neutralize the acidic chyme entering the small intestine from the stomach, creating a more suitable environment for digestive enzymes. Saliva (choice A) helps in the initial breakdown of food in the mouth, not in neutralizing stomach acid. Gastric mucus (choice B) protects the stomach lining from the acidic environment but does not neutralize the acid in the small intestine. Enzymes (choice D) facilitate chemical reactions in digestion but do not neutralize stomach acid.

2. Age group categories within older adults are classified as 'young old,' 'old,' and 'oldest old,' the latter of which comprises adults aged _____.

• A. 70-80 years
• B. 75-84 years
• C. 80-90 years
• D. 85 years or older

Correct answer: D

Rationale: The 'oldest old' category includes adults aged 85 years or older. This age group faces unique health challenges and requires specialized care. Choices A, B, and C are incorrect as they do not fall within the age range specified for the 'oldest old' category.

3. A client is experiencing sleep disturbances and desires to decrease caffeine intake. Which of the following beverages should the nurse recommend?

• A. Lemon-lime soda
• B. Brewed iced tea
• C. Diet cola
• D. Chocolate milk

Correct answer: B

Rationale: The nurse should recommend brewed iced tea as it generally contains less caffeine compared to other choices. Lemon-lime soda, diet cola, and chocolate milk all contain caffeine, which can contribute to sleep disturbances. Lemon-lime soda and diet cola are carbonated beverages that typically contain caffeine unless specified as caffeine-free. Chocolate milk also contains caffeine due to the cocoa content. Therefore, brewed iced tea is the most suitable choice to reduce caffeine intake and improve sleep quality.

4. The working phase in a therapy group is usually characterized by which of the following?

• A. Caution
• B. Cohesiveness
• C. Confusion
• D. Competition

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.

5. 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.
