Q

how do you determine total daily dose of insulin for treatment of T1DM

A

weight (KG) X variable factor (0.3-1) = total dose
divide TDD by 2 and do half in long action and the other half in short acting divided over 3 meals

25
what is 1st line for T2DM
metformin
26
how soon after starting metformin should you get follow up A1C
3 months
27
what is next step if, after 3 months of metform, A1C is >9.5%
start basal insulin (long acting)
28
what is next step if, after 3 months of metformin, A1C is between 7-9.5%
add second antidiabetic medication
29
what are options for add on antidiabetics
GLP-1 agonists SGLT2 inhibitors Thiazolinediones DPP4 inhibitors
30
what antidiabetic add on should be used for patients with CHF
SGLT2 inhibitors
31
when is next follow up after starting a 2nd antidiabetic
3 month
32
if after 3 months of metformin and 2nd antidiabetic, A1C is >9.5%, what is next step
start basal insulin
33
if after 3 months of metformin and 2nd antidiabetic A1C is between 7-9.5%, what is next step
add 3rd antidiabetic medication
34
if after 3 months of 3 antidiabetic medications A1C is >7%, what is next step
start basal insulin
35
what needs to be checked before starting insulin infusion in DKA and HHS
potassium must first be corrected
36
what medication should be used for proteinuria and/or HTN with DM
ACE-I or ARBs
37
what medication can be used for neuropathic pain in DM
gabapentin pregabalin TCAs SSRIs
38
when should patients be taking their own POC BG
when they are taking insulin more than once a day
39
when should DM patients do ketone testing
Type 1 pts during periods of illness with high BG levels or symptoms of DKA
40
when should you screen asymptomatic people for DM
obese with at least 1 risk factor: ethnicity cardiovascular disease HTN DLD PCOS sedentary family history of DM indication of insulin resistance
41
what are indications of insulin resistance
acanthosis nigricans severe obesity
42
what A1C level would be considered prediabetes and how often should you screen prediabetic individuals
>5.7% test yearly
43
if no indications to screen for DM earlier, at what age should all patients start to have screening for DM and how often should you repeat screening if normal
age 45 repeat every 3 years
44
what type of DM occurs in older adults with a slow surreptitious onset
latent autoimmune diabetes of adulthood (LADA)
45
which type of DM may be associated with thyroid disease
type 1
46
what is a normal A1C level
<5.7%
47
true or false: carb restricted diets are best for control of diabetes
false, reduced calories with lots of veggies is helpful but reducing carbs is no more helpful
48
when would you target an A1C <6.5% and less then 7%
7% = most people with DM >6.5% = T2DM with low risk of hypoglycemic events
49
what class of medication is metformin
biguanide
50
what are the main side effects of metformin
GI upset anorexia lactic acidosis
51
What are the contraindications for metformin
liver and renal dysfuction
52
how often do you increase metformin dosage and what is the max
gradually increase every week to a max of 2550mg
53
when would you start with lifestyle changes instead of metformin
if A1C is <1.5% over target
54
true or false: if new diabetic initially presents with symptoms (polyuria, polydipsia, weight loss, volume depletion) then you should start with insulin +/- metformin
true
55
liraglutide and semaglutide are what class of medication
GLP-1 receptor agonists
56
dapagliflozin is what class of medication
SGLT2 inhibitor
57
what oral antidiabetic medication should be stopped once you decide to start insulin and why
sulfonylureas as they are more likely to cause hypoglycemia
58
when should you start a GLP1-RA or SGLT2I even if A1C is at target
patients >60 with multiple risk factors, ASCVD, CHF, CKD as they provide cardio-renal protection
59
if weight loss is a priority, which medication should be chosen
GLP1RA or SGLT2I
60
what should GFR level be at in order to safely use a SGLT2I
>30
61
which medications should be witheld during acute illness
metformin and SGLT2I and insulin
62
what is the first priority for newly diagnosed diabetics if they are asymptomatic
getting BP to <130/80
63
what is the preferred first line HTN tx for DM
ACE-I or ARBs
64
what is 2nd and 3rd choice for HTN in DM
2nd = CCB 3rd = diuretic
65
what should you be aware of with thiazides and DM
should be used in low doses as large doses may worsen glucose control
66
why are beta blockers often not used in DM
they may mask the symptoms of hypoglycemia
67
which DM patients require statin treatment
CV disease, microvascular disease, >40 years old
68
which DM patients require statin and ACE-I/ARB therapy
Microvascular disease or >55 with additional risk factors
69
which DM patients require Statin, ACE-I and ASA therapy
CV disease (Cardiac ischemia, PAD, CVD, carotid disease)
70
what is the pneumonic SADMANS
the medication that should be held with vomiting/diarrhea Sulfonylureas Ace inhibitor Diuretics Metformin ARBS NSAIDs SGLT2I
71
what are lipid control goals for DM
LDL-C <2.0
72
when should you suspect LADA and how will you check for it
normal weight individuals who do not respond to treatment as well as normal T2DM order C-peptides which will be greatly reduced with LADA
