transfusion reaction
plasma proteins - Answer: albumin, fibrinogen, globulins. Proteins function to
control oncotic pressure, transport substances (hemoglobin, lipids, calcium), and
promote inflammation and the complement cascade.
action potential stages - Answer: 1) resting potential = Na+ ions outside while K+
ions inside
2) depolarization = Na+ channels open & Na+ comes in; cell becomes more
positive (meets threshold of -55 mV to fire)
3) repolarization = K+ channels open & K+ goes out; cell becomes more negative
4) undershoot = cell goes below resting potential; K+ channels are slow to close

, 5) return to resting potential = both channels close; Na+ & K+ pumps restore
concentration gradient

Na normal lab value - Answer: 135-145
K normal lab value - Answer: 3.5-5.0

Prader-Willi Syndrome - Answer: Caused by a lack of genetic material in the 15
pair of chromosomes. Usually inherited from the father. The leading genetic cause
of obesity. The degree of mental retardation varies, but is usually in the mild
range. Students with Prader-Willi syndrome can be rigid and oppositional. They do
not respond well to sudden changes in their routine. It can also result in low
muscle tone, short stature, incomplete sexual development, cognitive disabilities,
problem behaviors, and a chronic feeling of hunger that can lead to excessive
