1. Which of the following are considered normal values for the measure of a person’s pulse and blood pressure?

• A. 55 beats per minute and 75 over 60 mm Hg
• B. 72 beats per minute and 120 over 80 mm Hg
• C. 100 beats per minute and 140 over 100 mm Hg
• D. 160 beats per minute and 100 over 70 mm Hg

Correct answer: B

Rationale: Normal values for pulse rate typically range between 60 to 100 beats per minute, while normal blood pressure values are usually around 120/80 mm Hg. Option B falls within these normal ranges for both pulse rate and blood pressure, making it the correct choice. Choices A, C, and D have either pulse rate, blood pressure, or both values outside the normal ranges, making them incorrect.

2. What is the main function of the skeletal system?

• A. To produce red blood cells
• B. To protect internal organs and provide support
• C. To regulate body temperature
• D. To store calcium

Correct answer: B

Rationale: The main function of the skeletal system is to provide structural support, protect internal organs, enable movement, and maintain the body's form. Choice A, 'To produce red blood cells,' is incorrect as the skeletal system's role in blood cell production is through the bone marrow, not its main function. Choice C, 'To regulate body temperature,' is incorrect as the skeletal system is not primarily responsible for regulating body temperature. Choice D, 'To store calcium,' is partially correct as the skeletal system does store calcium but this is not its main function; instead, it is essential for bone strength and muscle function.

3. Which type of joint is found in the knee?

• A. Ball and socket joint
• B. Hinge joint
• C. Pivot joint
• D. Saddle joint

Correct answer: B

Rationale: The correct answer is a hinge joint. The knee is a hinge joint that allows for flexion and extension movements, enabling the leg to bend and straighten. This type of joint is designed for movement along one plane, similar to a door hinge. Choice A, ball and socket joint, is incorrect as this type of joint allows for a wider range of motion in multiple directions, unlike the knee joint. Choice C, pivot joint, and Choice D, saddle joint, are also incorrect as they do not accurately describe the type of joint found in the knee.

4. Which is another name for thiamine?

• A. Vitamin B1
• B. Vitamin B2
• C. Vitamin B6
• D. Vitamin D

Correct answer: A

Rationale: Thiamine is another name for Vitamin B1. It is an essential vitamin that plays a crucial role in energy metabolism and is important for the proper functioning of the nervous system. Vitamin B2 is riboflavin, not thiamine. Vitamin B6 is pyridoxine, not thiamine. Vitamin D is a different vitamin responsible for calcium absorption and bone health, not thiamine. Therefore, the correct answer is Vitamin B1.

5. How many bones are found in the human skull?

• A. Approximately 5
• B. Approximately 30
• C. Approximately 60
• D. Approximately 210

Correct answer: B

Rationale: The correct answer is B: Approximately 30. The human skull is composed of 22 bones that are fused together. These 22 bones consist of 8 cranial bones and 14 facial bones, totaling approximately 30 bones in total. Choices A, C, and D are incorrect because the human skull does not have as few as 5 bones, as many as 60 bones, or as many as 210 bones. Understanding the basic anatomy of the skull helps in identifying the correct number of bones it comprises.
