- A reaction to the environment by the body is known as a * (1) stimulus (3) reflex response (2) habit (4) sourcePain control system :-a- is activated whenever a painful stimulus is applied to body tissuesb- is never activated naturallyc- is activated only by administration of opiate drugsd- is activated naturally under conditions associated with strong emotional excitement1. What is homeostasis? a. Fluctuation between high and low valuesb. Ingestion of enough food to satisfy hungerc. Tendency of the body to maintain a stable internal environmentd. Ability to remain within certain limited ranges 2. How does negative feedback lead to homeostasis? a. It shuts off the original stimulus, or reduces its intensity.b. It amplifies the effect of stimulusc. Increasing the effect of an output 3. Which statement about positive feedback is false? a. Positive feedback is observed more readily than negative feedback.b. Positive feedback reaches a limit at which it terminates quickly.c. Positive feedback amplifies the response.d. Positive feedback is exemplified by sexual behavior. 4. As fruit ripens it emits a chemical called ethylene, which attracts fruit flies. The flies damage the fruit, causing more odor to be released. As this happens, more flies are attracted to the fruit. Of what response is this an example?a. Positive feedbackb. Negative feedbackc.…

- The body is divided into anterior and posterior portions by the ____________ plane. frontal horizontal sagittal transverseWhich factor have the most effect on a person’svital capacity? Rank in order from MOST effect (1) to least effect(5)The weight of the person The height of the person The sex of the person The age of the person Activity level (athletics)write a plan for your self a bout Maslow Theory include the description of the person, position and process
- The ________ of the zone of inhibition is always measured in _________. Multiple Choice diameter; mm diameter; cm radius; mm circumference; mmTrue or False? A person's sense of control is important to the experience of pain. Patients given the opportunity to self-administer morphine instead of asking a nurse for an injection feel less pain and require less morphine.Consider what you personally believe about pain: what it is,what causes it, what is most likely to relieve it. Determine how pain is currently being managed within the tradition of West-ern medicine and what role nursing plays in keeping patients pain free. Visit nontraditional health centers where practitio-ners use a variety of noninvasive pain relief modalities, such as acupressure, relaxation techniques, imagery, and massage. Inwhat ways, if any, has this new learning experience modifiedyour beliefs about pain? Will it change your ability to designeffective pain management regimens for your patients?
