69
intracellular
within the cell
70
Extracellular
outside the cell
71
interstitial
pertaining to spaces between cells in a tissue or organ
72
third space fluid
fluid found in the interstitial tissue space - Third space is also a term used to refer to, for example, the bowel with an ileus, and the collection of fluid therein, usually post-operatively.
73
Define the factors that influence the movement of fluid and electrolytes (F&E) and describe how each factor influences the movement of F&E. What increases/decreases the impact of these factors?
74
Hydrostatic pressure
the pressure created by water. Hydrostatic pressure creates a pushing motion of fluid. Anything that increases the amount of water in a container (cell, vascular space) increases the flow of water out of the container. Hydrostatic pressure is increased by adding water to the vascular space via IV for example.
75
colloidal
pertaining to a gluelike substance
76

Movement of molecules from an area of higher concentration to an area of lower concentration.
79
Osmosis
Diffusion of water through a selectively permeable membrane
80
Isotonic fluid
Any fluid having the same solute concentration as another fluid to which it is being compared. - Isotonic solutions have a concentration of dissolved particles similar to plasma, and an osmolality of 250 to 375 mOsm/L. - Common examples of isotonic solutions are 0.9% normal saline and lactated ringers.
81
a. What impact does isotonic fluid have on fluid shifts?
Because isotonic solutions have the same concentration of solutes as plasma, infused isotonic solution doesn't move into cells. Rather, it remains within the extracellular fluid compartment and is distributed between the intravascular and interstitial spaces, thus increasing intravascular volume.
82
b. What impact does isotonic fluid have on cell size?
If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, the relative concentrations of solute and water are equal on both sides of the membrane. There is no net water movement, so there is no change in the size of the cell.
83
Where does isotonic fluid stay?
Because isotonic solutions have the same concentration of solutes as plasma, infused isotonic solution doesn't move into cells. Rather, it remains within the extracellular fluid compartment and is distributed between the intravascular and interstitial spaces, thus increasing intravascular volume.
84
Name the isotonic fluids.
-0.9% Saline. -5% dextrose in water (D5W)**also used as a hypotonic solution after it is administered because the body absorbs the dextrose BUT it is considered isotonic) -5% Dextrose in 0.225% saline (D5W1/4NS) -Lactated Ringer's.
85
Hypotonic fluids
the #of particles in a solution on one side of a membrane is less than the # of particles in a solution on the other side of the membrane
86
What impact does hypotonic fluid have on fluid shifts?
When a hypotonic solution is administered intravenously, fluid shifts out of the bloodstream to the area of higher concentration in the interstitial and intracellular spaces.
87
What impact does hypotonic fluid have on cell size?
It also means that the extracellular fluid has a higher concentration of water in the solution than does the cell. In this situation, water will follow its concentration gradient and enter the cell, causing the cell to expand.
88
Where does hypotonic fluid have the propensity to go/stay?
A hypotonic solution has a low solute concentration than the inside of the cells (solute concentration in the cell is high). Osmotic forces then cause water from a solution to enter the cells. The cell eventually stretches and bursts in the process becoming lysis.
89
Name the hypotonic fluids:
Hypotonic: D5W (in the body) 0.25% NaCl. 0.45% NaCl (half normal saline) 2.5% Dextrose.
90
What impact does hypertonic fluid have on fluid shifts?
Hypertonic solutions such as 3% saline solutions contain higher concentrations of solutes than those found in human serum. Because of this discrepancy in concentration, these fluids are osmotically active and therefore, will cause fluid shifts
91
What impact does hypertonic fluid have on cell size?
Because the cell has a relatively higher concentration of water, water will leave the cell, and the cell will shrink.
92
Name the hypertonic fluids:
3% Saline. 5% Saline. 10% Dextrose in Water (D10W) 5% Dextrose in 0.9% Saline. 5% Dextrose in 0.45% saline. 5% Dextrose in Lactated Ringer's.
93

94
Dehydration causes
Vomiting and diarrhea Excessive sweating Untreated diabetes mellitus No access to water Lack of thirst in elderly
95
Dehydration signs and symptoms
-Weight losses of 6-10 pounds in one week -Tenting -Filling or emptying of venous filling more than 6-10 seconds -Flat veins in supine client -Tongue is dry -Sunken eyeballs -Blood pressure decreased with elevated pulse rate
96
Appropriate fluid types and specific fluids used for patient with dehydration:
Initial management includes placement of an intravenous or intraosseous line and rapid administration of 20 mL/kg of an isotonic crystalloid (eg, lactated Ringer solution, 0.9% sodium chloride). Additional fluid boluses may be required depending on the severity of the dehydration.
97
Overload
a condition in which a person feels overly pressured by demands
98
Overload causes
Heart failure. Cirrhosis. Kidney failure. Nephrotic syndrome. Premenstrual edema. Pregnancy.
99
Overload signs and symptoms
Rapid weight gain. Noticeable swelling (edema) in your arms, legs and face. Swelling in your abdomen. Cramping, headache, and stomach bloating. Shortness of breath. High blood pressure. Heart problems, including congestive heart failure.
100
Overload fluids used
Crystalloid fluids
101
Low fluid volume
Hypovolemic shock (hemorrhagic shock, non-hemorrhagic shock)
102
Signs and Symptoms of Fluid Volume Deficit
Postural hypotension Weight loss/Dryness Inelastic skin Increase pulse and respiration Renal failure Dizziness (orthostatic/postural hypotension) Decreased urination (oliguria) Dry mouth, dry skin. Thirst and/or nausea. Weight loss (except in third spacing, where the fluid will still be in the body but inaccessible) Muscle weakness and lethargy.
103
Low fluid volume causes
trauma to vessels or tissues, fluid loss from GI tract (vomiting/diarrhea)
104
What is the best indicator of fluid status? How should this assessment be conducted?
The elasticity of skin, or turgor, is an indicator of fluid status in most patients (Scales and Pilsworth, 2008). Assessing skin turgor is a quick and simple test performed by pinching a fold of skin. In a well-hydrated person, the skin will immediately fall back to its normal position when released.
105
How does antidiuretic hormone (ADH) effect fluid balance?
Antidiuretic hormone stimulates water reabsorbtion by stimulating insertion of "water channels" or aquaporins into the membranes of kidney tubules. These channels transport solute-free water through tubular cells and back into blood, leading to a decrease in plasma osmolarity and an increase osmolarity of urine.
106
How does obesity impact fluid balance?
Also, overweight and obese subjects demonstrated a significantly larger decrease in body mass after exercise than lean controls (P<0.05). Conclusion: Obese subjects demonstrate a larger deviation in markers of fluid and sodium balance than their lean counterparts during prolonged moderate-intensity exercise.
107
What is the recommended amount of daily fluid intake?
About 15.5 cups (3.7 liters) of fluids for men. About 11.5 cups (2.7 liters) of fluids a day for women
108
What is the volume to weight equivalent of water?
The density of water is 1 kilogram per liter(kg/L) at 39.2°. This means that 1 liter (L) of water weighs 1 kilogram (kg) and 1 milliliter (mL) of water weighs 1 gram (g).
109
Define obligatory urine output and what is the amount?
700mL per day, 30 mL per hour
110
Electrolytes listed below
An ionic compound whose aqueous solution conducts an electric current
111
Sodium
A. Extracellular B. Movement: If sodium ions are outside of a cell, they will tend to move into the cell based on both their concentration gradient (the lower concentration of Na +start superscript, plus, end superscript in the cell) and the voltage across the membrane (the more negative charge on the inside of the membrane). C. A normal blood sodium level is between 135 and 145 milliequivalents per liter (mEq/L).
112
Hypernatremia
- Hypernatremia is a serum sodium concentration > 145 mEq/L (> 145 mmol/L). It implies a deficit of total body water relative to total body sodium caused by water intake being less than water losses. - S&S: Hypernatremia typically causes thirst. The most serious symptoms of hypernatremia result from brain dysfunction. Severe hypernatremia can lead to confusion, muscle twitching, seizures, coma, and death.
113
Hyponatremia
- deficient sodium in the blood, is decrease in serum sodium concentration < 136 mEq/L -S&S: Nausea and vomiting. Headache. Confusion. Loss of energy, drowsiness and fatigue. Restlessness and irritability. Muscle weakness, spasms or cramps. Seizures. Coma.
114
Potassium
Potassium is a mineral and an electrolyte. It helps your muscles work, including the muscles that control your heartbeat and breathing. Potassiumcomes from the food you eat. Your body uses the potassium it needs. The extra potassium that your body does not need is removed from your blood by your kidneys. - It exists predominantly in the intracellular fluid at concentrations of 140 to 150 meq/liter and in the extracellular fluid at concentrations of 3.5 to 5 meq/liter. - Movement: It helps keep the water (the amount of fluid inside and outside the body's cells) and electrolyte balance of the body. Potassium is also important in how nerves and muscles work. Potassium levels often change with sodium levels. - Levels of potassium controlled by: The body maintains the right level of potassium by matching the amount of potassium consumed with the amount lost. Potassium is consumed in food and drinks that contain electrolytes (including potassium) and lost primarily in urine. Some potassium is also lost through the digestive tract and in sweat.

144
All cancers originate from changes in __________. i. Function of tumor suppressor genes ii. Function of oncogenes
I. Tumor suppressor genes are normal genes that slow down cell division, repair DNA mistakes, or tell cells when to die (a process known as apoptosis or programmed cell death). When tumor suppressor genes don't work properly, cells can grow out of control, which can lead to cancer. ii. An oncogene is a gene that has the potential to cause cancer. In tumor cells, these genes are often mutated, or expressed at high levels. ... If, through mutation, normal genes promoting cellular growth are up-regulated (gain-of-function mutation), they will predispose the cell to cancer; thus, they are termed "oncogenes".
145

161
What types of cells does chemotherapy target? What are the effects on cells not affected by cancer?
- Chemotherapy is most effective at killing cells that are rapidly dividing. - Unfortunately, chemotherapy does not know the difference between cancer cells and the normal cells. The "normal" cells will grow back and be healthy but in the meantime, side effects occur. -Cancer is the uncontrolled growth of abnormal cells in the body. Cancer develops when the body's normal control mechanism stops working. Old cells do not die and instead grow out of control, forming new, abnormal cells. These extra cellsmay form a mass of tissue, called a tumor.
