Answer to Question 1
A
To control or eliminate infection in reservoir sites, eliminate sources of body fluids, drainage, or solutions that possibly harbor microorganisms such as a Foley collection bag. Try not to work with patients who are highly susceptible to infection if you have a cold or other communicable infection. Another way of controlling the exit of microorganisms is by using standard precautions when handling body fluids such as urine, feces, and wound drainage. Wear clean gloves if there is a chance of contact with any blood or body fluids, and perform hand hygiene after providing care. Be sure to bag contaminated items appropriately.
Answer to Question 2
C
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. The physiological response intensifies, but the person has so little energy left that adaptation to the stressor diminishes. The body can no longer defend itself against the impact of the event, and if the stress continues, it damages the heart along with other bodily organs and lowers resistance to illness. In the alarm stage, rising hormones result in an increased blood pressure, blood glucose levels, epinephrine and norepinephrine levels, heart rate, blood flow to muscles, oxygen intake, and mental alertness. This change in body systems prepares an individual for fight or flight and lasts from 1 minute to many hours. During the resistance stage, the body stabilizes and responds in an opposite manner to the alarm stage.
