Isotonic IV solution Correct Answer--NS, LR -expand intravascular and extracellular fluid -most common Hypotonic IV solution Correct Answer--.45 Saline -osmosis of fluid into the cell Hypertonic IV solution Correct Answer--3% Saline, 5% dextrose -moves intracellular fluid into vasculature Plasma expanded IV solution Correct Answer--albumin, plasma -stay in the vascular space and increase the osmotic pressure Lab work for dyspnea and edematous lower legs Correct Answer--CBC -el...

Fluid regulation mechanisms - Answer--The thirst center. The thirst center in the hypothalamus stimulates or inhibits the desire for a person to drink. -Antidiuretic hormone. ADH regulates the amount of water the kidney tubules absorb and is released in response to low blood volume or in response to an increase in the concentration of sodium and other solutes in the intravascular fluids. -The RAAS. The RAA system controls fluid volume, in which when the blood volume decreases, blood flow t...

Stages of general adaptation syndrome - 1. Alarm Initial reaction Sympathetic nervous system 2. Resistance Adaptation Limit stressor 3. Exhaustion Adaptation failing Disease develops Edema - Excess fluid in the interstitial space Dehydration (ECF volume deficit) - Can occur independently without electrolyte defects Decrease in fluid level leads to increase in level of blood solutes Cell shrinkage Hypotension Hypovolemia or fluid volume deficit - Decreased fluid in the intravascular...
