1. Scoliosis is a condition characterized by abnormal lateral curvature of the spine. Which part of the spine is most commonly affected?

• A. Cervical spine (neck)
• B. Thoracic spine (upper back)
• C. Lumbar spine (lower back)
• D. All of the above

Correct answer: B

Rationale: The correct answer is B: Thoracic spine (upper back). Scoliosis typically affects the thoracic spine more commonly than the cervical or lumbar spine. The thoracic spine, which is the upper back region, is the most common area for the abnormal lateral curvature of the spine to occur in cases of scoliosis. This is due to the natural curvature and structure of the spine in this region. While scoliosis can affect other parts of the spine as well, the thoracic spine is most frequently impacted, making it the correct answer in this case.

2. What is the difference between active and passive immunity?

• A. Active immunity is short-lived, while passive immunity is long-lasting.
• B. Active immunity involves the body's own immune response, while passive immunity provides immediate protection through antibodies from another source.
• C. Active immunity only protects against bacterial infections, while passive immunity works against both bacteria and viruses.
• D. Passive immunity requires repeated vaccinations, while active immunity is a one-time process.

Correct answer: A

Rationale: The correct answer is A: "Active immunity involves the body's own immune response, while passive immunity provides immediate protection through antibodies from another source." Active immunity is long-lasting because it involves the body's immune system producing memory cells that remember specific pathogens, providing long-term protection. Passive immunity, on the other hand, is short-lived as it involves receiving pre-formed antibodies from an external source, such as through maternal transfer or injection of antibodies, which do not create memory cells for long-lasting protection.

3. What kind of lens focuses parallel light rays to a single point?

• A. Concave lens
• B. Convex lens
• C. Cylindrical lens
• D. Plano lens

Correct answer: B

Rationale: Convex lenses (converging lenses) bend incoming light rays inwards, focusing them to a point called the focal point.

4. You need to paint a rectangular swimming pool with dimensions 8m by 5m and a depth of 2m. Considering only the interior walls and floor (not the top), how much paint do you need (assume one can of paint covers 10 sq m)?

• A. 56 sq m
• B. 72 sq m
• C. 88 sq m
• D. 104 sq m

Correct answer: C

Rationale: Calculate the areas of each wall and the floor, sum them up, and subtract the area of the water surface (top). Divide the final area by the coverage area per can to determine the number of cans needed.

5. Which pattern of nursing care involves the care given by a group of paraprofessional workers

• A. Case method
• B. Modular nursing
• C. Nursing case management
• D. Team nursing

Correct answer: A

Rationale: The correct answer is A: 'Case method.' The case method of nursing care involves the care provided by a group of paraprofessional workers, such as nursing assistants or aides, under the supervision of professional nurses. In this model, the nursing team works together to deliver care to a group of patients based on their specific needs and conditions. This method allows for efficient and coordinated care delivery, with each member of the team playing a crucial role in meeting the patients' healthcare needs. It is important for nurses to effectively delegate tasks and supervise paraprofessional workers in the case method model to ensure high-quality care and patient safety.

6. What type of force allows a car to take a sharp turn while moving in a circular path?

• A. Centripetal force
• B. Tension force
• C. Frictional force
• D. Gravitational force

Correct answer: A

Rationale: Centripetal force is the force that allows an object to move in a circular path. In the case of a car taking a sharp turn, the centripetal force is directed towards the center of the circle, keeping the car moving in a curved path. Tension force is the force transmitted through a string, rope, cable, or wire when it is pulled tight by forces acting from opposite ends. Frictional force opposes the motion of an object and is not the primary force responsible for allowing a car to take a sharp turn. Gravitational force is the force of attraction between two masses and is not directly related to a car taking a sharp turn.
