CSF total protein is considered to be what percentage of the total blood protein value?
- 0.5-1.0%
- 60-70%
- 20-30%
- 10-15%
0.5-1%
A patient goes to the ER with increased fluid retention in the chest and complains of pain when taking a breath (pleuisy). The doctor removes fluid from the chest and it reveals increased white and red cell counts, low protein, and has a notably odor. What procedure was utilized to extract the fluid and what type of fluid resulted from the extraction?
- Thorocentesis, exudate
- Paracentesis, exudate
- Pleuralcentesis, transudate
- Thorocentesis, transudate
Thorocentesis, exudate
A cloudy synovial fluid with a WBC count of 150,000, no viscosity, and monosodium urate crystals noted is consistent with which process?
- inflammatory
- non-inflammatory
- hemorrhagic
- crystal induced
crystal induced
Which of the following conditions is associated with the formation of an exudate?
- Congestive heart failure
- Pneumonia
- Cirrhosis
- Nephrotic syndrome
pneumonia
-exudate: form from primary problem
- transudate: form secondary to another disorder
Electrolyte essential for myocardial contraction and important to maintain normal levels for critically ill patients.
- chloride
- calcium
- sodium
- zinc
calcium
A patient presents to the ER with severe dehydration, dilute urine production, and constant “thirst” sensation. It is revealed that the patient had recently (1 week ago) fallen off a ladder and suffered trauma to the head. Given this information, what lab test should be performed?
- ADH/AVP
- aldosterone
- renin
- angiotensinogen
ADH/AVP
- ADH is responsible for thirst mechanism and is released from pituitary gland in brain
Second most abundant anion in extracellular fluid.
- chloride
- phosphate
- carbonic acid
- bicarb
bicarb

- 92
- 8
- 45
- 72
92
What is the best interpretation of the following results?
pH=7.33 (7.35-7.45)
CO2= 27 (35-45)
HCO3= 14 (22-29

HCO3
True or False
The unique structure of hemoglobin allows it to act as both an acid-base buffer and O2 buffer.
True
An increase in H+ ions, a decrease in pH, and a decrease in HCO3 results in what acid-base disorder?
