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. A person who has damage to their ulnar nerve will have decreased sensation in which part of the body?

• A. Hand
• B. Arm
• C. Leg
• D. Foot

Correct answer: A

Rationale: Corrected Rationale: Damage to the ulnar nerve typically results in decreased sensation in the hand, particularly affecting the little finger and half of the ring finger. The ulnar nerve innervates the hand and is responsible for providing sensation to these areas. This nerve does not extend to the leg or foot, so choices C and D are incorrect. While the ulnar nerve travels through the arm, its primary sensory impact is felt in the hand, making choice B less specific and therefore not the best answer.

3. Which organ system is primarily responsible for integrating voluntary movements?

• A. Cardiovascular system
• B. Digestive system
• C. Respiratory system
• D. Nervous system

Correct answer: D

Rationale: The correct answer is D: Nervous system. The nervous system is primarily responsible for integrating voluntary movements. This system includes the brain, spinal cord, and peripheral nerves that communicate signals throughout the body to control movement. The brain interprets sensory information, formulates decisions, and sends signals to the muscles to execute voluntary movements. The cardiovascular system is responsible for circulating blood, the digestive system for breaking down food and absorbing nutrients, and the respiratory system for gas exchange in the body. Choices A, B, and C are incorrect as they do not play a primary role in integrating voluntary movements.

4. Which hormone is involved in the regulation of water balance in the body?

• A. ADH
• B. Insulin
• C. Cortisol
• D. Thyroxine

Correct answer: A

Rationale: The correct answer is ADH (antidiuretic hormone), also known as vasopressin. ADH helps regulate water balance in the body by controlling the amount of water reabsorbed by the kidneys. When there is a need to conserve water, ADH levels increase, leading to more water reabsorption and concentration of urine. Insulin is involved in regulating blood sugar levels, not water balance. Cortisol is a stress hormone that helps regulate metabolism and immune response, not water balance. Thyroxine is a thyroid hormone that regulates metabolism, growth, and development, not water balance.

5. Which of the following is true about skeletal muscle?

• A. Skeletal muscle makes up 40% of the body's weight.
• B. Skeletal muscle attaches to bones by tendons.
• C. Muscle contraction is not involved in temperature regulation.
• D. Skeletal muscles contract only when in use.

Correct answer: B

Rationale: The correct statement is that skeletal muscle attaches to bones through tendons, enabling movement. Tendons connect muscles to bones and allow the force generated by muscle contraction to be transmitted to the bones, facilitating voluntary movements. Choice A is incorrect because skeletal muscle typically makes up around 40-50% of an individual's body weight, not a fixed 40%. Choice C is incorrect as muscle contraction plays a vital role in temperature regulation by generating heat. Choice D is incorrect as skeletal muscles may have constant low-level contractions even at rest, known as muscle tone.
