2. He discusses the goal of the department. Which of the following statements is a goal?
- A. Increase the patient satisfaction rate
 - B. Eliminate the incidence of delayed administration of medications
 - C. Establish rapport with patients.
 - D. Reduce response time to two minutes.
 
Correct answer: A
Rationale: Option A, 'Increase the patient satisfaction rate,' is a goal because it represents an objective that the department aims to achieve. Patient satisfaction is a key indicator of quality care and reflects the department's commitment to providing excellent service. In contrast, options B, C, and D are more focused on specific actions or strategies rather than overarching goals. Eliminating delayed medication administration, establishing rapport with patients, and reducing response time are important tasks that may contribute to achieving the goal of increasing patient satisfaction, but they are not goals in themselves. Therefore, option A is the most appropriate choice as it directly addresses the department's ultimate objective of enhancing patient satisfaction.

5. What type of bone is the kneecap (patella)?
- A. Long bone
 - B. Short bone

Correct answer: B
Rationale: The correct answer is B: Short bone. The kneecap, or patella, is classified as a short bone because it is roughly cube-shaped and is composed of spongy bone enclosed by a thin layer of compact bone. Short bones provide support and stability with limited motion, making them ideal for protecting joints like the knee. Long bones are typically elongated, flat bones are thin and curved, and irregular bones have complex shapes. Understanding the classification of bones can help in identifying their functions and structural characteristics.
