1. What is a common finding in a whiplash injury?

Correct answer: D

Rationale: A common finding in a whiplash injury is a traumatic injury to ligaments. Whiplash occurs due to sudden hyperextension and hyperflexion of the neck, leading to strain or tearing of ligaments in the neck. This can manifest as neck pain, stiffness, and limited range of motion. While other complications like cardiopulmonary problems, side-to-side spinal curvature, or eventual herniation of discs are not typically associated with whiplash injuries.

2. Which structure in the eye is responsible for focusing light on the retina?

Correct answer: B

Rationale: The lens of the eye is responsible for focusing light onto the retina. It plays a crucial role in bending light rays to ensure that they converge on the retina, enabling clear vision. The cornea helps in focusing light, but the final adjustment and fine-tuning occur through the lens. The retina receives the focused light and converts it into neural signals for the brain to interpret. The pupil, on the other hand, controls the amount of light entering the eye by dilating or constricting.

3. What type of joint is found in the shoulder?

Correct answer: A

Rationale: The correct answer is a ball and socket joint. The shoulder joint is a ball and socket joint, allowing for a wide range of motion, including rotation. This joint provides excellent flexibility and mobility, making movements like circular motions and rotations possible. A hinge joint, like the elbow, allows movement in only one plane (flexion and extension). A saddle joint, found in the thumb, allows for a wide range of motion but not as much as a ball and socket joint. A pivot joint, such as the joint between the first and second vertebrae of the neck, allows rotation only.

4. Which type of blood vessel carries blood away from the heart?

Correct answer: B

Rationale: Arteries are blood vessels that carry oxygenated blood away from the heart to the rest of the body. They have thick, muscular walls to withstand the high pressure generated by the heart's contractions, ensuring efficient transport of blood throughout the body. Veins, on the other hand, carry deoxygenated blood back to the heart, while capillaries facilitate the exchange of nutrients, oxygen, and waste products between the blood and tissues. Nerves are not involved in the transport of blood.

5. What is the role of the spleen in the lymphatic system?

Correct answer: A

Rationale: The spleen plays a crucial role in the lymphatic system by filtering blood, specifically removing old or damaged red blood cells. Additionally, the spleen produces lymphocytes, a type of white blood cell that plays a key role in the immune response by helping to fight off infections. Therefore, the correct answer is A, as the spleen is primarily involved in blood filtration and the production of lymphocytes rather than storing vitamins or regulating body temperature.
