NURS 130 EXAM QUESTIONS AND ANSWERS
LATEST UPDATE 2024
How is glucose regulation achieved?
1- nutrients
2- hormone signaling
3- Glocose uptake by cell
Glycogen***
Storage form of glucose
Glycogenolysis ***
the breakdown of the body stored glucose glycogen to use for glucose.
Gluconeogenesis
the making of glucose from a noncarbohydrate source such as amino acids or
glycerol
What is the term we use to describe normal blood suger levels?
,euglycemia
What is insulin?***
The cell cannot use glucose without insulin.
We use the locking key method, but if there is a cell and there's glucose, glucose
is not getting into that cell unless insulin is present.
So insulin is a necessary life-sustaining hormone that allows the cell to
To uptake glucose.
The pancreas uses what type of cell..to make insulin??..***.
Beta cells
whats the difference between Glucagon from Glycogen??
Glycogen is just stored glucose.
Be very careful hese words all look alike!!!
Think "Gone"= insulin gone!!!
Glucogon - is a hormone that is released also by the pancreas, the role of
glucagon, it's released by the alpha cells in the pancreas, is to counter-regulate
the insulin. What that means is glucagon will actually increase our blood sugar!!
,What are three main reasons that hyperglycemia occurs?
1- not enough insulin production
2- excessive counter-regulatory hormone secretion
3- deficient hormone signialing
What are some "physiological" consequences of hyperglycemia??
1- Angiopathy (disease of the blood vessels)
2- peripheral neuropathy (damaged by high sugar)
3- fluid, electrode, acid balance imbalances (dehydration too)
Think heart, disease, strokes, retinopathy, nephropathy increase risk for
infection!!!
When you think about DM patients you should be concerned about there....
Kidneys and eyes!
, retinopathy, nephropathy
What are the three main reasons that hypoglycemia occurs?
- adverse medication
- excessive exercise
- not eating enough
What are some "physiological" consequences of hypoglycemia??
-nervousness and axienty
Chronic repeated episodes of hypoglycemia will make the patient unaware that
their sugar is that low because their body just becomes used to the low sugar
levels, which is very dangerous. Hypoglycemia is absolutely a medical emergency.
If a patient is on Metformin, when is a time when we must hold the metformin?
So we're holding that form in when someone's getting IV contrast. stop taking it
and hold it for 48 hours after getting IV contrast. Otherwise we can cause serious
problems
We don't use metformin for a patient who has a _____ issues??
KIDNEY DISEASE It can interact with the kidneys, It can cause kidney issues. We do
not use this medication if someone has kidney disease!!
