$$BSA = \sqrt{\frac{H \times W}{3600}}$$

Question 1

Which of the following best describes the function of the lymphatic system in human physiology?

Accepted Answer

It returns interstitial fluid to the bloodstream and plays a role in immune defense.

Question 2

A patient presents with pale skin and fatigue. Blood tests reveal a low red blood cell count. Which system is most directly responsible for these symptoms, and what is its primary function?

Accepted Answer

The circulatory system; transporting nutrients and gases.

Question 3

Which equation best represents the relationship between cardiac output ($$CO$$), heart rate ($$HR$$), and stroke volume ($$SV$$)?

Accepted Answer

$$CO = HR 	imes SV$$

Question 4

Which layer of the skin is primarily responsible for providing a barrier against pathogens and preventing water loss?

Accepted Answer

Epidermis

Question 5

A person suffers a spinal cord injury and loses sensation in their legs. Which system is most directly affected, and what is its main function?

Accepted Answer

Nervous system; transmitting signals between the brain and body.

Question 6

Which of the following best describes the process of gas exchange in the respiratory system?

Accepted Answer

Oxygen diffuses from alveoli into capillaries, while carbon dioxide diffuses from capillaries into alveoli.

Question 7

Which equation correctly represents the calculation of mean arterial pressure ($$MAP) $$given systolic ($$SBP) $$and diastolic ($$DBP) $$blood pressures?

Accepted Answer

$$MAP = DBP + \frac{1}{3}(SBP - DBP)$$

Question 8

A patient with a damaged pancreas is unable to regulate blood glucose levels. Which system is primarily affected, and what is its main function?

Accepted Answer

Endocrine system; hormone regulation.

Question 9

Which of the following is a function of the skeletal system?

Accepted Answer

Providing structural support and protecting internal organs.

Question 10

A person is exposed to a pathogen. Which system is responsible for mounting an immune response, and what is a key component of this system?

Accepted Answer

Lymphatic system; lymph nodes.

Question 11

Which of the following best describes the function of the digestive system?

Accepted Answer

Breaking down food and absorbing nutrients.

Question 12

A patient has a blockage in a coronary artery. Which system is affected, and what is the likely consequence?

Accepted Answer

Circulatory system; reduced blood flow to heart tissue, potentially causing a heart attack.

Question 13

Which equation represents the calculation of body surface area ($$BSA) $$using the Mosteller formula, given height ($$H) in cm $$and weight ($$W) in kg$$?

Accepted Answer

$$BSA = \sqrt{\frac{H 	imes W}{3600}}$$

Question 14

Which of the following is a primary function of blood in the human body?

Accepted Answer

Transporting oxygen, nutrients, and waste products.

Question 15

A patient with severe burns loses the protective function of their skin. Which consequence is most likely?

Accepted Answer

Increased risk of infection and dehydration.

Question 16

Which of the following best describes the role of sensory organs in the human body?

Accepted Answer

They detect environmental stimuli and transmit information to the nervous system.

Question 17

Which equation best represents the calculation of respiratory minute volume ($$RMV$$), given tidal volume ($$TV) $$and respiratory rate ($$RR$$)?

Accepted Answer

$$RMV = TV 	imes RR$$

Question 18

A patient with a damaged thyroid gland is experiencing symptoms of fatigue and weight gain. Which system is affected, and what is its primary function?

Accepted Answer

Endocrine system; regulating metabolism through hormone secretion.

Question 19

Which of the following best describes the function of the nervous system?

Accepted Answer

Transmitting electrical and chemical signals to coordinate body functions.

Question 20

A patient is unable to absorb nutrients properly due to a damaged small intestine. Which system is affected, and what is its main function?

Accepted Answer

Digestive system; breaking down food and absorbing nutrients.
