Answer to Question 1
A
During the alarm reaction, rising hormone levels result in increased blood volume, blood glucose levels, epinephrine and norepinephrine levels, heart rate, blood flow to muscles, oxygen intake, and mental alertness. In addition, the pupils of the eyes dilate to produce a greater visual field. During the resistance stage the body stabilizes and responds in an opposite manner to the alarm reaction. In the adaptation stage, antiinflammatory adrenocortical hormones are released, and healing occurs. However, if the stressor remains and adaptation does not happen, the person enters the third stage, exhaustion. The exhaustion stage occurs when the body is no longer able to resist the effects of the stressor and the struggle to maintain adaptation drains all available energy.
Answer to Question 2
C
Disinfection eliminates almost all pathogenic organisms, with the exception of bacterial spores. Sterilization eliminates or destroys all forms of microbial life, including spores. Cleaning involves removing organic material such as blood or inorganic material such as soil from objects. Generally this involves the use of water, a detergent/disinfectant, and proper mechanical scrubbing action. Cleaning occurs before disinfection and sterilization procedures.
