Pressure that is due to albumin in the bloodstream? - ANSWER-Oncotic
Oncotic - ANSWER-a form of osmotic pressure exerted by proteins
In the blood, _____ is the most common plasma protein and is, therefore, a primary determinant of oncotic pressure - ANSWER-albumin
_____ controls osmotic pr...
One question was about the difference in children and adult immunity - ANSWER-Possible answer:
naive T cells
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 - 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.
Buffers, renal compensation, and respiratory compensation help to maintain a blood pH of _______ -
ANSWER-7.35-7.45
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 - 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
To prevent changes in pH, the body employs buffer systems. The body utilizes 3 buffer systems: -
ANSWER-proteins, phosphates, and the carbonic acid-bicarbonate system
Carbonic acid-bicarbonate system first line of defense is _____, second line of defense is _____ -
ANSWER-respirations; kidneys
Carbonic acid-bicarbonate system equation - ANSWER-The equation moves in both directions
CABS Equation:
When CO2 levels are elevated, the equation moves ________, forming more H+ and HCO3- ions -
ANSWER-toward the right
CABS Equation:
When H+ ions are elevated, the equation moves _____, as H+ ions are converted to CO2 and the CO2
is exhaled. - ANSWER-toward the left
,CO2 levels - ANSWER-35-45
HCO3 levels - ANSWER-22-26
Michael's pulmonary edema leads to respiratory acidosis. How does pH impact Michael's basal
metabolic panel? Choose 3 answers.
His CO2 level is increased because his lungs have difficulty removing it from the bloodstream.
His K+ is elevated because, as H+ moves inside of cells in an attempt to get it out of the bloodstream,
K+ moves from cells into the bloodstream.
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.
Fluid and electrolyte levels are regulated by _______, which regulates actions such as thirst, ADH, the
kidneys, and RAAS. - ANSWER-osmoreceptors
A hormonal panel was done on a patient with congestive heart failure and fluid volume overload.
Which elevated hormone on the patient's chart is indicative of the body's attempt to reduce the fluid
overload? - ANSWER-BNP - it's released when fluid volume excess is present
Compare and contrast hemodialysis and peritoneal dialysis - ANSWER-Hemodialysis:
-machine pumps blood from the body and filters waste
