Pressure that is due to albumin in the bloodstream?
Correct Answer
Oncotic


Question 2
Oncotic
Correct Answer
a form of osmotic pressure exerted by proteins


Question 3
In the blood, _____ is the most common plasma protein and is, therefore, a primary determinant of oncotic pressure
Correct Answer
albumin


Question 4
_____ controls osmotic pressure in vascular system, builds volume
Correct Answer
Albumin

,Question 6
Learning check question: Which differences in immunity make children and older adult patients more susceptible to
infections? Choose 2 answers

Younger patients have fewer memory cells to combat infection

Older adult patients have a dwindling population of naive T cells

Older adult patients have more memory cells to combat infection

Younger patients have a large population of naive T cells

Older adult patients have a large population of naive T cells
Correct Answer
Younger patients have fewer memory cells to combat infection

Older adult patients have a dwindling population of naive T cells

Rationale: younger patients have not been exposed to many pathogens, which means that they have fewer memory cells
than adults. The primary immune response is relatively weak compared to a secondary response mediated by memory
cells.

Older adult patients do not have as many T cells compared to younger patients. When these patients encounter novel
pathogens, the reduced number of naive T cells gives clonal selection fewer opportunities to "find" T cells that will be
effective.

,Question 10
Fluid deficit manifestations
Correct Answer
-dry mucous membranes
-decreased skin turgor
-decreased urine output
-low blood pressure
-tachycardia
-confusion


Question 11
ROME for ABGs
Correct Answer
Respiratory Opposite Metabolic Equal

If pH and pCO2 are moving in opposite directions, then it is pCO2 levels that are causing the imbalance and it is
respiratory in nature
If they are moving the same direction then it is metabolic in nature


Question 12
Buffers, renal compensation, and respiratory compensation help to maintain a blood pH of _______
Correct Answer
7.35-7.45


Question 13
A patient with a viral illness and severe vomiting has an elevated CO2 level and a blood pH of 7.53. She is breathing slowly.
What condition does the patient have?

Metabolic alkalosis
Metabolic acidosis
Respiratory alkalosis
Respiratory acidosis
Correct Answer
Metabolic alkalosis

The patient's pH and CO2 level are both elevating (moving in the same direction). This indicates metabolic alkalosis. The
CO2 level is high because her respiratory system is attempting to compensate for the high pH by exhaling less and
retaining more CO2


Question 14
To prevent changes in pH, the body employs buffer systems. The body utilizes 3 buffer systems:
Correct Answer
proteins, phosphates, and the carbonic acid-bicarbonate system

, Question 15
Carbonic acid-bicarbonate system first line of defense is _____, second line of defense is _____
Correct Answer
respirations; kidneys


Question 16
Carbonic acid-bicarbonate system equation




Correct Answer
The equation moves in both directions


Question 17
CABS Equation:
When CO2 levels are elevated, the equation moves ________, forming more H+ and HCO3- ions
Correct Answer
toward the right


Question 18
CABS Equation:
When H+ ions are elevated, the equation moves _____, as H+ ions are converted to CO2 and the CO2 is exhaled.

Correct Answer
toward the left


Question 19
CO2 levels

Correct Answer
35-45


Question 20
HCO3 levels
Correct Answer
22-26
