HNF 471 QUIZ 2 LABS EXAM QUESTIONS AND ANSWERS WITH
COMPLETE SOLUTIONS VERIFIED
Define serum and plasma
Both are the liquid part of blood without cells
Quesitons on exam:
-What are the lab values consistent with what do they support in terms of
diagnosis
-Malnutrition
-Nitiriton assoc. Anemias (know these lab values very well for exam)
-DOnt need to know about all of this (dont need to know about calcium)
What counts as plasma
-Water
-Albumin
-Globulins
-Amino Acids
-Hormones and enzymes
-Nitrogenous waste
-Nutrients
-Gases
-Fibrinogen
What counts as serum
,-Water
-Albumin
-Globulins
-Amino Acids
-Hormones and enzymes
-Nitrogenous waste
-Nutrients
-Gases
What doesn't count as serum
Fibrinogen
What influences labs
Hydration, making it tricky to evaluate labs
Give an example of how hydration makes it difficult to evaluate labs
(overhydration vs underhydration)
Overhydrated,as evidenced by edema, will "dilute" values, making some of them appear
lower than they actually are.
Restore fluid balance, and the values will return to normal
67YO female admitted after an episode of syncope after bowel prep for
colonoscopy.
status (incr).
Explain the following lab values that are not WNL
, Na and BUN are high.
Think of the body as a garden: high Na and BUN levels are like too much salt and
fertilizer, causing the plants (your body) to wilt and struggle after a big cleaning session.
Not only will underhydration increase lab values but also...
increased inflammation = increased positive acute phase respondents due to surgery or
chronic obesity
inflammation will decrease what respondents?
negative acute phase respondents. Albumin decreases in the presence of inflammation,
it does not determine protein deficiency
How will vomitting and diarrhea make lab values appear, how do you fix this?
Lab values will appear higher due to dehydration
Restore fluid balance, and the values will return back to normal.
Serum osmolarity helps asses _________________. If lab values are low vs high
what is this due to?
hydration status.
Serum osmolarity - measure of the amount of nutrients in the liquid part of your blood
stream
If low, lab values will likely be low due to over hydration.
