1. Which of the following is a chronic lung disease that results in the gradual destruction of the alveoli, causing difficulty breathing and reduced oxygen exchange?
- A. Emphysema
- B. Bronchitis
- C. Pulmonary hypertension
- D. Sarcoidosis
Correct answer: A
Rationale: Emphysema is the correct answer as it is a chronic lung disease characterized by the gradual destruction of the alveoli, which are essential for oxygen exchange. This destruction leads to difficulty breathing and reduced oxygen levels in the blood. Bronchitis is an inflammation of the bronchial tubes, not specifically involving alveoli destruction. Pulmonary hypertension is a condition of high blood pressure in the arteries of the lungs, not directly related to alveoli destruction. Sarcoidosis is a disease characterized by the growth of tiny collections of inflammatory cells in different parts of the body, including the lungs, but it does not primarily involve the destruction of alveoli.

- 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.

Rationale: The primary advantage of utilizing a modular nursing model is enhanced teamwork and collaboration among nurses. While improved patient satisfaction, cost reduction, and improved communication are essential in healthcare settings, the modular nursing model specifically focuses on restructuring care delivery to promote teamwork and efficiency. Therefore, choices A, C, and D are not the primary advantages of using a modular nursing model.
5. Baby Gabriella claps her hands after her mother does. Gabriella is displaying __________.
- A. reinforcement

Rationale: Observational learning is when an individual learns by watching others and mimicking their actions or behaviors. In this scenario, Baby Gabriella claps her hands after her mother does, indicating she is learning through observing her mother's behavior and imitating it. The other choices are incorrect: Reinforcement typically involves a consequence that strengthens a behavior, classical conditioning is a type of learning where an association is made between two stimuli, and adaptation refers to the process of adjusting to new conditions.
