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. Which of the following HDL cholesterol levels might warrant regular testing?

• A. 70 or higher
• B. 60
• C. 50
• D. 40

Correct answer: A

Rationale: An HDL cholesterol level of 70 or higher is considered high and beneficial for heart health. Individuals with high HDL levels are usually at lower risk of heart disease. Therefore, a level of 70 or above would warrant regular testing to monitor and maintain heart health. Choices B, C, and D are lower levels of HDL cholesterol, which are not typically considered high enough to warrant regular testing as they may not provide the same level of heart health benefits.

3. Which vitamin is essential for blood clotting?

• A. Vitamin C
• B. Vitamin K
• C. Vitamin D
• D. Vitamin B12

Correct answer: B

Rationale: Vitamin K is essential for blood clotting as it is necessary for the synthesis of proteins involved in the coagulation process, such as clotting factors. Without sufficient Vitamin K, the blood may not clot properly, leading to excessive bleeding. Vitamin C is important for collagen synthesis and immune function, Vitamin D is essential for calcium absorption and bone health, and Vitamin B12 is crucial for red blood cell formation and neurological function. However, when it comes to blood clotting, Vitamin K plays a vital role.

4. What is the primary function of the liver?

• A. Detoxifying harmful substances
• B. Producing bile
• C. Producing insulin
• D. Storing glycogen

Correct answer: A

Rationale: The primary function of the liver is to detoxify harmful substances in the blood. While the liver also produces bile, which aids in digestion, stores glycogen for energy storage, and participates in metabolism, its main and essential function is detoxification. Producing insulin is mainly attributed to the pancreas, not the liver.

5. What is the primary function of white blood cells?

• A. To carry oxygen
• B. To fight infections
• C. To transport nutrients
• D. To clot blood

Correct answer: B

Rationale: White blood cells, also known as leukocytes, play a crucial role in the immune system by primarily fighting off infections caused by pathogens like bacteria, viruses, and other invaders. They help the body recognize and destroy these harmful agents, contributing to the body's defense mechanisms against diseases. Choice A is incorrect because the primary function of red blood cells, not white blood cells, is to carry oxygen. Choice C is incorrect as the transportation of nutrients is mainly carried out by the bloodstream as a whole, not specifically by white blood cells. Choice D is incorrect as the process of blood clotting is primarily managed by platelets in the blood, not white blood cells.
