Q

discuss interstitial fluid. where can it be and what does it look like on an assessment?

A

Interstitial fluid is found between cells. Usually found in synovial fluid in joints, cerebral spinal fluid, and ocular fluid in the eyes. Looks like edema.

Q

discuss what and how diffusion, filtration, and osmosis work in the human body and is it active or passive transportation?

A

Diffusion - the process of “being widely spread,” is the random movement of molecules from an area of higher concentration to an area of lower concentration. Passive.

Filtration - the transport of water and dissolved materials through a membrane from an area of higher pressure to an area of lower pressure. Passive.

Osmosis - the diffusion of a pure solvent, such as water, across a semipermeable membrane in response to a concentration gradient, in situations where the molecules of a lower concentration to higher concentration are non-diffusible. Passive.

neuromuscular and cardiac function is the responsibility of what electrolyte
potassium
29
what is the drug tx of choice for the patient who has hyperkalemia
loop diuretic such as Lasix (furosemide) if renal fx is adequate. Kayexalate (sodium polystyrene sulfonate)
30
neuromuscular and cardiac function is the responsibility of what electrolyte
hypokalemia
31
would your patient who has either hypo or hyper K+ have ECG/EKG changes
Both
32
what is the most accurate way to dertermine your patients water balance/imbalance
Daily weight at the same time.
33
what are the definitions and the normal ranges for HCO3, PaCO2, pH, Pao2

34
what largest fluid compartment found in the body is
intracellular
35
what is the s/s of hypocalcemia
tingling. numbness and tingling around the mouth, facial twitching (chvostek's sign), carpopedal spasm (trousseau's sign), laryngeal spasm, laryngeal stridor, abdominal and muscle cramps, bleeding, and fractures
36
describe what metabolic acidosis patients ABG's look like. Describe the possible cause/s

muscle weakness. It puts you at risk for respiratory compromise.
56
metabolic acidosis causes the heart to increase or decrease why

58
Discuss the causes of hypovolemia
``` abnormal GI loses diaphoresis third spacing hemorrhage altered intake ```

64
what is the normal urine specific gravity range
1.005- 1.030
65
what would be the s/s of dehydration
