Answer to Question 1

A
Feedback:
A client with quadriplegia may face the highest risk of lack of oxygen. Quadriplegia or paralysis of all four limbs may stop the functioning of some parts of the client's body, which may also affect the functioning of lungs and affect breathing. Dehydration and unconsciousness can be caused as a result of lack of water and fluid in the body. High blood pressure does not maximize the risk of lack of oxygen.

Answer to Question 2

A
Feedback:
The principal arteries that supply the heart muscle with blood are the right and left coronary arteries. The pulmonary arteries are the only arteries in the body that carry deoxygenated blood. The pulmonary veins are the only veins that carry oxygenated blood.
