Ch.27 Fluid,E-, & Acid-Base balance Flashcards
What is the most abundant ICF cation
K+
What is the most abundant ICF anion
Proteins
What is the most abundant ECF cation
Na+
What is the most abundant ECF anion
Cl-
What 2 pressures are the major forces of fluid movement in and out of the blood(HO)
Hydrostatic and osmotic pressure
What is another name for solutes found in the ECF
Electrolytes
What term represents below normal Na+ levels
hyponatremia
What term represents abnormally high K+ levels in the ECF
Hyperkalemia
What term represents overly high levels of Ca2+
Hypercalcemia
When there is too much calcium in the ECF, what moves it to the bones to decrease these levels
Calcitonin
When calcium levels in the ECF are low, what pulls calcium from bones and other organs to increase these levels
PTH
T/F When you see high blood osmolality, you can assume that means that BV/BP are low with both resulting in an increase in ADH
True
Causes of Hypocalcemia
Lack of Calcium food
Lack of Vitamin D
Staying indoors
Conditions of regulation of Sodium Ion
• Hypernatremia: elevated plasma Na+
• Hyponatremia: decreased Na+
T/F The inhibition of angiotensin II also inadvertently inhibits ADH and aldosterone
True
What term represents below normal levels of magnesium
Hypomagnesemia
T/F If magnesium levels are not properly corrected it could cause other ions to become unbalanced
True
What term represents lower than normal levels of phosphate
hypophosphatemia
What releases H+ ions into a solution
Acids
What removes H+ from solutions or adds OH- to solutions
Base
T/F The physiological pH range, in human terms, is slightly alkaline based on the pH scale
True
When pH drops below the normal range you enter a state of what
Acidosis
When pH exceeds the normal range you enter a state of what
Alkalosis
Proteins and carbonic acid/bicarbonate drive what buffering system
chemical buffer system
Which buffer system is the most important intracellularly and involves 2 organ systems
physiological buffer system
Hypoventilation causes increased amounts of CO2 and H+ resulting in what
respiratory acidosis
Hyperventilation causes CO2 to be lost at greater rates along with H+, what is the result of this
respiratory alkalosis
When your kidneys secrete H+ and reabsorb HCO3- what do you get
metabolic alkalosis
Acid/Base Determination (Primary…) If pH is lower than the lowest limit, your answer ends in __ If pH is higher than the top limit, your answer ends in __ If HCO3- is normal and PaCO2 is outside its range, the answer includes __ If HCO3- is outside its range and PaCO2 is normal, the answer includes __
acidosis, alkalosis, respiratory, metabolic
Find the Acid/Base Disturbance pH=7.48 (7.35-7.45) PaCO2=40 mmHg (35-45) HCO3-=32 mEq/L (22-26)
primary metabolic alkalosis
Find the Acid/Base Disturbance pH=7.30 (7.35-7.45) PaCO2=50 mmHg (35-45) HCO3-=24 mEq/L (22-26)
primary respiratory acidosis
T/F An increase in CO2 in the respiratory system equals an increase in H+ and because H+ is an acid, you end up in an acidosis state
True
An increase in the production of aldosterone increases sodium and water reabsorption, but it also increases the secretion of what 2 ions/cations when you have what
K+ and H+ when you have hyperkalemia
