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. Which plane would you use to separate the abdominal cavity from the thoracic cavity?

• A. Sagittal
• B. Transverse
• C. Frontal
• D. Coronal

Correct answer: B

Rationale: The transverse plane, also known as the horizontal plane, runs horizontally from left to right, dividing the body into superior (upper) and inferior (lower) parts. This plane is ideal for separating the abdominal cavity (located below) from the thoracic cavity (located above). The sagittal plane (choice A) divides the body into left and right portions, the frontal plane (choice C) divides the body into front and back portions, and the coronal plane (choice D) is another term for the frontal plane. Therefore, when looking to separate the abdominal cavity from the thoracic cavity, the transverse plane is the most appropriate choice.

3. Which vitamin is important for blood clotting?

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

Correct answer: B

Rationale: Vitamin K is crucial for the synthesis of proteins involved in blood clotting, aiding in the prevention of excessive bleeding. Without sufficient Vitamin K, the blood may not clot properly, leading to an increased risk of bleeding and other related complications. Vitamin C is essential for collagen synthesis and the immune system, not specifically for blood clotting. Vitamin A is important for vision and immune function. Vitamin D plays a role in calcium absorption and bone health, but it is not directly linked to blood clotting.

4. What is the primary hormone secreted by the thyroid gland?

• A. Oxytocin
• B. TSH
• C. Adrenaline
• D. T4

Correct answer: D

Rationale: The correct answer is D: T4. The primary hormone secreted by the thyroid gland is thyroxine, also known as T4. T4 plays a crucial role in regulating metabolism, growth, and energy levels in the body. It is converted into the more active form, triiodothyronine (T3), which exerts most of the biological effects of thyroid hormones. Choices A, B, and C are incorrect. Oxytocin is not produced by the thyroid gland but by the pituitary gland, TSH (thyroid-stimulating hormone) is secreted by the pituitary gland to stimulate the thyroid gland, and adrenaline is produced by the adrenal glands, not the thyroid gland.

5. What is the function of the adrenal glands?

• A. To regulate blood sugar
• B. To produce hormones
• C. To produce red blood cells
• D. To filter blood

Correct answer: B

Rationale: The adrenal glands function to produce hormones such as adrenaline and cortisol. These hormones play essential roles in regulating metabolism, immune response, and the body's response to stress. Therefore, the correct answer is that the adrenal glands produce hormones. Choices A, C, and D are incorrect as regulating blood sugar is primarily done by the pancreas, producing red blood cells is the function of the bone marrow, and filtering blood is carried out by the kidneys, not the adrenal glands.
