Q

What can hypokalemia lead to?

A

GI disturbances, decreased skeletal muscle function and dysrhythmias

17
Q

What can hyperkalemia lead to?

A

Hyperstimulation of cell transmission and cardiac arrest

18
Q

Principal cation needed for bone growth?

19
Q

What can hypocalcemia lead to?

A

Overstimulation of nerve cells, skeletal muscle cramps, abdominal cramps, carpo-pedal spasms, hypertension, and vasoconstriction

20
Q

What can hypercalcemia lead to?

A

Decreased stimulation of nerve cells, skeletal muscle weakness, lethargy, ataxia, vasodilation, and flush skin

21
Q

What electrolyte is the primary buffer that determines difference between metabolic acidosis or alkalosis

A

HCO3- (bicarbonate)

22
Q

Electrolyte that primarily regulates the pH of the stomach

23
Q

Concentration gradient

A

Tendency for materials to flow from an area of high concentration to low concentration. Can be chemical or electrical.

24
Q

Diffusion

A

The process of compounds or charges concentrated on one side of the membrane move across to an area of low concentration

25
Type of diffusion used by the kidneys
Filtration
26
Prevents the loss of water from the kidneys by causing reabsorption into the tubules
Antidiuretic hormone (ADH)
27
Active transport and an example
The method used to move compounds to create or maintain an imbalance charges. Sodium potassium pump uses ATP.
28
Osmosis
Water will flow across the membrane from the solution of lower solute concentration to the solution of higher concentration in order to equalize solute concentration
29
Define tonicity
The concentration of sodium in a solution and the movement of water in relation to sodium levels inside and outside the cell
30
How much fluid does a healthy person lose per day?
2-2.5 liters
31
Two categories of IV solutions
Crystalloid solutions and colloid solutions
32
What is a crystalloid solution?
Fluids with dissolved sugars or salts with the ability to cross cellular membranes. May interfere with hemostasis (blood clotting)
33
What is a colloid solution?
Solution with high osmolarity that draws fluid from the interstitial intracellular compartments into the vascular compartments, but is unable to pass out of the capillary membrane
34
What is the 3:1 rule of fluid replacement?
3 mL of isotonic crystalloid solution is needed to replace 1 mL of blood
35
Three categories of tonicity and examples
Isotonic - .9% NaCl, LRs, same osmolarity of body fluids Hypertonic - D5W, water is pulled from the vascular compartment and cells may swell and burst Hypotonic - 9.0% NaCl, pulls fluid from the intracellular and interstitial compartments and into the intravascular compartment, cells may collapse, stabilizes BP
36
What is special about a volutrol (burette, buretrol)?
Contains a 100-200ml calibrated drip chamber to allow for volume specific fluid administration for pediatric or geriatric pts. Helps avoid inadvertent fluid overload
37
What location of IV cannulation may place a pt. in greater risk of venus thrombosis or pulmonary embolisms?
Lower extremities
38
Advantages and disadvantages of butterfly needles
Advantage: easy, scalp veins in pecs and good for difficult geriatric veins Disadvantages: infiltration, small gauge limits flow
