1. What is the average normal body temperature in degrees Celsius?

• A. 30°C
• B. 32°C
• C. 35°C
• D. 37°C

Correct answer: D

Rationale: The average normal body temperature in degrees Celsius is 37°C. This temperature is considered the standard measurement for the human body under normal conditions. It is essential to know this baseline temperature for monitoring health and detecting abnormalities such as fever. Choice A, 30°C, is too low for the average normal body temperature. Choice B, 32°C, is also below the standard normal body temperature. Choice C, 35°C, is closer but still lower than the average normal body temperature of 37°C.

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

• A. Cardiopulmonary issues
• B. Side-to-side spinal curvature
• C. Eventual herniation of discs
• D. Traumatic injury to ligaments

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.

3. Which part of the brain is responsible for regulating emotions and memory?

• A. Cerebrum
• B. Cerebellum
• C. Amygdala
• D. Brainstem

Correct answer: C

Rationale: The amygdala, located in the temporal lobe of the brain, is responsible for regulating emotions and memory, particularly those related to fear and pleasure. It plays a crucial role in processing emotional responses, forming emotional memories, and modulating emotional reactions. The cerebrum (Choice A) is responsible for higher brain functions such as thought and action. The cerebellum (Choice B) is mainly involved in coordination and balance. The brainstem (Choice D) controls basic life functions such as breathing and heart rate.

4. Which vitamin is essential for maintaining healthy skin and vision?

• A. Vitamin C
• B. Vitamin A
• C. Vitamin D
• D. Vitamin K

Correct answer: B

Rationale: Vitamin A is the correct answer. It is essential for maintaining healthy skin and vision, especially in low-light conditions. Vitamin A helps in the production of retinal pigments necessary for vision in dim light and supports skin health by promoting cell turnover and repair. Choice A, Vitamin C, is important for the immune system and collagen production but is not specifically known for maintaining skin and vision health. Choice C, Vitamin D, is crucial for bone health and immune function but is not directly related to skin and vision health. Choice D, Vitamin K, is necessary for blood clotting and bone health but does not play a significant role in maintaining healthy skin and vision.

5. The hypothalamus is part of the ___________.

• A. cardiovascular system
• B. endocrine system
• C. respiratory system
• D. lymphatic system

Correct answer: B

Rationale: The hypothalamus is a small region of the brain that plays a crucial role in linking the nervous system to the endocrine system. It helps regulate various bodily functions by releasing hormones that signal the pituitary gland to release other hormones that control metabolism, growth, reproduction, sleep, and other important processes. Therefore, the hypothalamus is a key component of the endocrine system. Choices A, C, and D are incorrect because the hypothalamus is not part of the cardiovascular, respiratory, or lymphatic systems.
