a. Contain more Na+ (20-30 mmol/L) and less K+ (40-70mmol/L)
b. They’re maintenance crystalloid solutions
c. Contain less Na+ (40-70 mmol/ L) and more K+ (20-30mmol/L)
d. Used in paitents that have been stabilized by replacement fluids or those with low amounts for daily needs
a. Contain more Na+ (20-30 mmol/L) and less K+ (40-70mmol/L)
All of the following are true about crystalloids except:
a. Cause no change in electrolytes
b. Used in dehydrated patients
c. Avoid hypoalbuminemia
d. All the above are true
d. All the above are true
Which of the following is true:
a. Physiological saline (0.9% NaCl) are used for rapid IVF expansion if replacement solutions are unavailable
b. Low volumes of Physiological saline may dilute other electrolytes
c. Physiological saline is recommended for treating hypokalemic patients
d. Physiological saline is recommended for hyponatremic patients with hypoadrenocorticism
d. Physiological saline is recommended for hyponatremic patients with hypoadrenocorticism
15% BW makes up ____ TBW in the interstitial fluid.
3/12
5% BW and ____ TBW is found in the intravascular fluid.
1/12
Whch of the following is TRUE regarding the cell membrane?
a. permeable to water and impermeable to ions
b. permeable to water and small ions
c. permeable to water and impermeable to proteins
d. all the above are true
a. permeable to water and impermeable to ions
Which electrolyte is the backbone of ICF ions?
K+
True/False: The interstitial fluid and intravascular fluid make up the intracellular fluid.
False
** they make up the extracellular fluid
True/False: Na+ is the main electrolyte of the ECF since its found at high levels in the plasma (IVF) and interstitial fluid (ISF).
True
Which of the following is considered the backbone of the intravascular fluid (IVF)?
a. K+
b. Na+
c. protein
d. B and C
e. None of the above
c. protein
** Na+ is also found in high amounts in the IVF but its the backbone of the ECF
Which of the following definitions is correct?
a. isontonic has a small effect on RBC’s
b. Hypertonic expands RBC’s causing hemolysis
c. Hypotonic expands RBC’s causing hemolysis
d. Hypotonic shrinks RBC’s
c. Hypotonic expands RBC’s causing hemolysis
remember that there is a different effect on the cells than the name implies –> hypertonic will shrink the cells
Which is the most important determinant of colloid oncotic pressure?
Albumin
____ antagnoizes osmosis during fluid shifts driving fluid outwards.
Hydrostatic pressure
True/False: At the venous end of the capillary bed moves fluidbback into the IVF and the lymphatics are responible for moving the remainder of the ICF into the IVF.
True
What are the three forces that move both water and ions across the cell membrane and capilalry bed?
Osmolality
Colloid oncotic pressure
Hydrostatic pressure
What kind of fluids are Ringers, Plasmalyte R/ Normosol R?

a. Colloids
b. Blood products
c. Cyrstalloids
d. Oncoids
c. Cyrstalloids
All of the follwoing are true about hypertonic saline (7.5% NaCl) except:

c. It has a large molecular weight
d. Replaces large volumes of blood loss at 3:1 v/v ratio
d. Replaces large volumes of blood loss at 3:1 v/v ratio
low blood loss at 1:1 ratio
