SLCC Pathophysiology - Unit 2
Integrative Body Functions Exam
Questions and Answers
Osmosis - Answer-The movement of fluid through a semipermeable membrane. Low to
high concentration.

Hypo/hyper volemia - Answer-Low/high blood volume

Desiccation - Answer-The shriveling of cells. Crenate for RBC

Jugular Vein Dystention - Answer-JDV, putting pressure on the vein

Hydrostatic pressure - Answer-Pushes fluid out of blood vessel into the tissue on the
arterial side of capillaries

Osmotic pressure - Answer-The pull that attracts fluid out of tissue back into the blood
vessel on the venous side of capilaries

Molecules with osmotic pressure - Answer-Protein, glucose, and sodium

Tonicity of IV fluids - Answer-Number/size of molecules in a solution determines which
direction fluids flows.

Isotonic - Answer-Most commonly used. Causes no change in cell size as fluid moves
back and forth. 0.9% Saline and LR

Hypertonic - Answer-Fluid is attracted from tissue into blood. Large molecules like
Proteins and Glucose attract water.

When would you give a Hypertonic solution? - Answer-1:Rapid fluid replacement or
tissue is over hydrated.
2: Extreme loss of blood or the blood vessels need to be filled up with fluid to keep the
person from losing BP or dying.
3: When tissue is Over-Hydrated (as in edema or third spacing) to pull fluid out of tissue.

Hypertonic solutions - Answer-Albumin, D50W, hetastarch, > 0.9% like 3% and 6%
saline.

Hypotonic - Answer-Fluid moves from blood to tissue. Given when tissue is dehydrated.
0.45% Saline (1/2 NS) and D5W.

, D5W - Answer-5% Dextrose for first 10 minutes (ISO)--> then it is absorbed and left with
water-->Hypotonic

Tissue Dehydration - Answer-Diabetic keto acidosis and severe burns.

S/S of hypervolemia - Answer-Increase in BP, Dyspnea, Fluid in lungs, JVD, Edema,
and Bounding pulse.

S/S of hyovolemia - Answer-Decrease in BP, lightheaded, dizzy, weak pulse

Fluid overload - Answer-Caused by to much fluids, excess fluid in vessels pushed into
interstitial tissue. Lungs - drown patient

Fluid challenge - Answer-IV fluid given in 500 ml increments. Then assessed and
repeated if necessary.
1 L of fluid for each: 10 decrease in systolic and 10 increase in HR.

Edema - Answer-Swelling of interstitial tissue

Edema effects - Answer-Impaired blood flow,
reduced healing,
toxins increased because wastes can't leave,
increased workload on heart (increased blood pressure)

Life threatening edema - Answer-Laryngeal edema-airway blockage
Pleural edema-breathing impared
Cerebral edema-fluid crushes brain

Third spacing - Answer-Too much fluid moves from intravascular space to interstitial
space. Can cause edema, reduced cardiac output, and hypotension

Causes of edema - Answer-Increased capillary pressure
Decreased colloidal osmotic pressure
Increased capillary permeability
Obstruction of lymphatic flow

Measure of edema - Answer-Dependent edema and daily weights

Dependent edema - Answer-Common finding in heart failure. (In legs)

Daily weight - Answer-Done at same time with similar clothing, after voiding. Gives info
on fluid weight/gain.

Treatment of edema - Answer-Diuretic medications (Pee more) and hypertonic fluids
(pulls fluid out of tissue to be peed out by kidneys).
