Q

Diabetes: Where does energy come from when someone is in DKA and body doesn’t have enough energy?

25
DKA: What occurs in DKA?
There is not enough insulin this results in hyperglycemia, dehydration, and electrolyte loss along with acidosis
26
DKA: What do kidneys do here?
they try to excrete the excess glucose , and that is why there is dehydration and electrolyte imbalance
27
DKA: Why does the body go into acidosis?
Because the body is trying to break down fats for energy causing ketone bodies which leads to acidosis.
28
DKA: Important for Diabetics to follow Sick Day Rules, which include what?
Take insulin as usual Test glucose/ketones every 3-4 hours Report elevated glucose Take supplemental glucose ever 3-4 hours as needed Sub soft foods if needed Take liquids every 30- 1 hour to prevent dehydration
29
DKA: What are the three main causes of this?
Either decreased or missed doses of insulin Illness/infection Undiagnosed/untreated diabetes.
30
DKA: What happens when patients are sick and they don't eat enough food?
It could throw them into DKA
31
DKA: How do you prevent this when sick?
Continue to take insulin Check glucose levels/ketones every 3-4 hours Be in contact with provider. Sub foods for soft foods. Stick to meal plan.
32
DKA - CMs: What are the first three main ones we may see?
Polyuri, Polydipsia, Fatigue
33
DKA - CMs: What are some other signs that they may have?
Hypotension due to volume depletion Acidotic Fruity Breath
34
DKA - CMs: What GI symptoms may they have?
Anorexia, N/V, abdominal pain
35
DKA - CMs: What is the hallmark sign of this?
Fruity breath due to buildup of ketones
36
DKA - CMs: How will their respiration's be?
Kussmaul Respirations (deep, rapid breathing). they are in metabolic acidosis and are trying to breathe off the CO2.
37
DKA - CMs: Mental status can vary how?
Some can be in coma, or some can be alert.
38
DKA - CMs: Assessment will focus on what?
The clinical manifestations. Assessing for dehydration, blood pressure, gi status, fruity breath, kuzzmal breathing.
39
DKA - Diagnostics: What will their glucose level be at?
300-800.
40
DKA - Diagnostics: How will their abg levels be?
In metabolic acidosis Will have decreased bicarb. pH will be less than 7.35. Respiratory system may try to compensate for this
41
DKA - Diagnostics: Urine test will reveal what?
Ketones present in the urine
42
DKA - Diagnostics: Albumin and creatinine will be what?
Will both be increased
43
DKA - Mx: What is the number one management way?
Rehydration. First start with normal saline.
44
DKA - Mx: What will first be given for dehydration?
A bolus on normal saline, around 0.5 - 1L / hr over 2/3 hours.
45
DKA - Mx: After the normal saline is given, what will then be given?
1/2 NS at 200-300 mL / hr. Have to keep an eye on glucose
46
DKA - Mx: Why do you have to keep an eye on glucose as you rehydrate an individual?
BEcause as the glucose continues to be brought down, the glucose level will need to be switched once below 300
47
DKA - Rehydration Mx: Once BS < 300, what will be given?
Will be switched to D5W and actually given a little bit of dextrose as well.
48
DKA - Rehydration Mx: What electrolyte will be a big concern?
Potassium. Will usually see elevated potassium and will start to go down because patient is receiving a lot of fluids and insulin. Shifts potassium into cell.
49
DKA - Rehydration Mx: What is a treatment of hyperkalemia?
Insulin
50
DKA - Rehydration Mx: So while potassium is being corrected, what else is being corrected?
Metabolic Acidosis through insulin
51
DKA - Mx: To ensure they are recovering, what must you do?
Get labs every 2-4 hours. EKGs done more frequently. Frequent monitoring.
52
DKA - Mx: Why is the patient acidotic?
Because of the ketone bodies that have accumulated related to fat breakdown for energy.
53
DKA - Mx: How will the patients acidosis be fixed?
Through Insulin IV drip. Will be getting glucose every hour.
54
DKA - Mx: We wont give bicarb to correct acidosis to DKA patients why?
Because it will eventually correct itself normally
55
DKA - Mx: When giving insulin, what must we keep in mind when we are hanging?
We must flush insulin because it tends to stick to the tubing. Make sure 50 mL are flushed through IV set because it will stick to tubing.
56
Nickname for Hyperglycemic Hyperosmolar Syndrome?
HHS
57
HHS: What is the official name of this?
Hyperglycemic Hyperosmolar Syndrome
58
HHS: Sometimes referred to as HH NKS, which is what?
Non-Ketonic Syndrome
59
HHS: This will typically affect what patient?
Those with Type 2 DM and older
60
HHS: This is usually initiated by what?
Illness that raises the demand for insulin
61
HHS: Why don't you see acidosis with this?
Because there is not the ketosis that is going on. They still have insulin in circulation so they don't develop acidosis.
62
HHS: They will have an increase in what?
blood sugar, which causes the kidneys to try to get rid of all this extra sugar/glucose and see osmotic diuresis
63
HHS: How long does this take to progress
This can progress over days to weeks
64
HHS - CMs: What changes will start to occur?
Decreased blood pressure (hypotension) Dehydration (bc of diuresis) Tachycardia Mental status varies (seizures)
65
HHS - CMs: Decreased blood pressure and dehydration is coming from what
osmotic diuresis that happens because body is trying to get rid of excess glucose.
66
HHS - Assessments: You will be looking at what glucose level?
Looking at glucose level of 600 - 1200
67
HHS - Assessments: What will patient be assessed for?
Signs they are experiences so blood pressure and dehydration that matches with high glucose levels. Elevated BUN / Creatinine.
68
HHS - Mx: What three things cna be done to manage this?
Fluid replacement Electrolyte correction Insulin
69
HHS - Mx: How long will this take to correct?
Usually 3-5 days, especially if theyre having AMS.
