NUR 339 Exam 15
- active transport
low -> high needs energy
movement of solutes from area of lower concentration to higher concentration *requires energy
- osmosis
movement of water from area of more water (less solutes) to less water (more solutes) through semipermeable membrane
- Regular insulin
given IV DKA/HHS; acute/emergency used with NPH
sliding scale 30-45m before meals
*hypoglycemia more likely during peak onset
30m-1h (IV 15-30m)
peak
2-3h duration
5-7h 1 / 3
- rapid acting lispro insulin
use
faster onset, shorter duration
- used with NPH
- 15m before meals
- slidin
g scale onset
15 min peak
1-3h duration
3-8h
- electrolytes
substances that dissociate in solution to charged particles (ions)
- interstitial hydrostatic pressure
opposes movement of water out of capillary, normally negative
- fluid volume overload
intake > output
- Capillary colloidal osmotic pressure 2 / 3
osmotic pressure generated by plasma proteins too large to pass through pores of capillary wall, pulls fluids back into capillary
"c" - collide together
- Chloride
Major ECF anion
key role in acid-base & osmotic balance and energy (ATP)
- electrolyte key functions
regulate water transmit nerve impulses & muscle contractions acid-base balance
energy generation blood clotting
- D5W in 0.45% NaCl
hypotonic solution used TKO & supply calories for cell metabolism used when running fluids slowly
- diffusion
movement of solutes from an area of high concentration to lower concentration direction opposite of osmosis
- hypokalemia
