If some one has come bk from surgery and had anesthesia what are the two high risk patients the nurse should really look out for?
-Those with liver and kidney disease.
Induced state of partial or total loss of sensation, occurring with or without loss of consciousness. Used to block nerve impulse transmission, suppress reflexes, promote muscle relaxation, and in some instances achieve a controlled level of unconsciousness.
-Reversible loss of consciousness.
-State can be achieved by a single agent or a combination of agents.
-Central nervous system is depressed resulting in analgesia, amnesia and unconsciousness with loss of muscle tone and reflexes.

This electrolyte is a major cation in the extracellular fluid and is responsible for maintaining extracellular fluid osmolarity.
This electrolyte is responsible for skeletal muscle and cardiac contraction, nerve impulse transmission.
What symptoms will a patient have when they have hypernatremia?
It causes shift of fluid out of the cells and then causes neuromuscular irritability.
The function of this electrolyte functions include the regulation of protein synthesis, glucose use and storage, and maintenance of action potential in excitable membranes.
this electrolytes levels in the blood and interstitial fluid are very low, so change seriously affects physiologic activities.
If an ng tube is in the pt what electrolyte should be infusing b/c the tube is sucking it out?
What is the treatment for hyperkalemia and how does it work?
Kayexalate and it pulls potassiumbk in to the gut and then the person poops it out.
What is the max infusion rate with potassium?
5-10 mEq/hr the rate should never exceed 20 mEq/hr under any circumstances.
What does blood do when calcium levels are too high or too low?
Too high your blood can clot
Too low you can bleed
This electrolyte is and important maintenance of bone strength and density activation of enzymes or reactions, skeletal and cardiac muscle contraction, nerve impulse transmission, and blood clotting?
If a pt has hypocalcemia what are they at risk for and what should you do to help prevent it?
Seizures and keep the environment stress free.
If a pt has diarrhea and they are not absorbing potassium what type of monitor do you need to put them on?
What symptoms do you get with hypophosphatemia?
-Musculoskeletal (acute muscle breakdown, or rhabdomyolyis)
Problems caused by hyperphosphatemia center on the hypocalcemia that results when serum phosphorus levels increase.
What electrolyte is usually off when you are an alcoholic b/c they are usually malnourished?
What electrolyte is responsible for this:
-Skeletal muscle contraction
-adenosine triphosphate formation
-B-complex vitamin activation
-DNA and protein synthisis
-Extracellular magnesium regulates blood coagulation and skeletal muscle contractility
This imbalance causes increased membrane excitability and the accompanying serum calcium and potassium imbalances.
With this electrolyte imbalance excitable membranes may not respond to any stimulus.
What types of things would we ask/assess for, for fluid and electrolyte balance?
-Physical assessment-assess for hydration
-Psychosocial assessment-psychological factors that may effect balance.
-Diagnostic assessment-laboratory assessment.
Occurs when fluid intake is less than needed to meet the body's fluid needs, resulting in a fluid volume deficit.
What is an expected lab finding for some one who is dehydrated?
In the absence of hemmorrhage, overall hemo-concentration.
When some one is dehydrated what 2 organs will take over as a compensatory mechanism?
heart it pumps faster so HR will increase, person may develop CHF. and kidneys but they usually take days to respond.
One of the risks of dehydration is decreased cardiac output the HR will increase, what does this put you at risk for?
This is an expression of the balance b/t co2, regulated by the lungs and bicarbonate regulated by the kidneys.
