Exam 1 Fundamentals Flashcards
1
Q
semi-fowlers

Used for feeding, lung expansion, cardiac or respiratory conditions, for pts with a nasogastric tube
2
Q
hypokalemia
A
symptoms: muscle weakness, chronic fatigue, and cardiac dysrhythmias
3
Q
Leukopenia
A
condition where a person has a reduced number of white blood cells. This increases their risk of infections
4
Q
leukocytosis
A
high WBC count
5
Q
Z-track method of drug injection
A
for intramuscular injections to prevent leakage of medication into the needle track into subcutaneous tissue, thus minimizing discomfort.
procedure: attach a clean needle to the syringe after the syringe is filled with the medication to prevent the injection of any residual medication on the needle into superficial tissues. Pull the skin down or to one side 1 to 2cm (Yilmaz et al., 2016; Karch, 2020), spread the skin taut at the injection site, and hold in this position with the nondominant hand. Insert the needle and inject the medication slowly. After 10 seconds, withdraw the needle steadily and release the displaced tissue to allow it to return to its normal position. Massage of the site is not recommended because it may cause irritation by forcing the medication to leak back into the needle track. However, gentle pressure may be applied with a dry sponge.

Q
the pain process
A
receive pain stimulus- activate the receptors(transduction)-
send a message via nerve fibers (transmission) to the thalamus- sensory center- heat, cold, pain, and touch are first perceived.
Then the cerebral cortex identify the intensity and location of the pain (perception)
brain messages to release endorphins & neuromodulators which are sent to diminish pain messages(modulation).

cultural assimilation
When a minority group lives within a dominant group, many members may lose the cultural characteristics that once made them different, and they may take on the values of the dominant culture.
ie. when people immigrate and encounter a new dominant culture as they work, go to school, and learn the dominant language, they often move closer to the dominant culture. The process and the rate of assimilation are individualized.
92
culture shock
when placed in a different culture they perceive as strange.
Culture shock may result in psychological discomfort or disturbances, because the patterns of behavior a person found acceptable and effective in their own culture may not be adequate or even acceptable in the new culture.
The person may then feel foolish, fearful, incompetent, inadequate, or humiliated. These feelings can eventually lead to frustration, anxiety, and loss of self-esteem
