A

no ADH being made
give ddavp

Q

old lady asymptomatic euvolemic hypotonic hyponatremia suggesting SIADH, next step correct hyponatremia or something else?

A

CT for lung cancer (small cell)
MRI brain for post pit tumor source would be next if chest CT negative

she is asymptomatic and euvolemic so no need to treat now… if coma or seizure give 3% hypertonic saline… anything less than that saline fluids will only make worse because will retain fluid but excrete sodium… only worsening condition… do probably Water Restrict, Salt Tablets, maybe anti-adh / blocker Demeclocycline… effectively inducing neprhogenic DI to treat SIADH… maybe limited use of 3%NS hypERtonic saline for Profound hyponatremia with Symptoms

Q

nephrogenic diabetes insipidus, think of 2 meds

A

Li (side effect, bipolar disorder)

Demeclocycline - induce nephrogenic DI (block ADH receptors) to treat SIADH (too much ADH)

Q

when to start insulin injections for diabetic

A

failure of oral meds

even if A1c is 15, start on orals if not already, and diet and exercise, give them a shot before insulin injections

Q

3 special health maintanence screenings for diabetics

A

peripheral neuropathy - monofilament / podiatry

retinopathy - annunal eye exams /ophtho

nephropathy - microalbuminuria/creatinine ratio

17
Q

best screening test for patient at risk for diabetes

A

fasting glucose ^125 (on two occasions)
cheap, effective, sufficient - no confirmatory test required

not a1c… on the test, but in life sometimes

18
Q

when is oggt used to screen for diabetes

A

fasting glucose positive ^125
but second is negative v125

then get ogtt

19
Q

how high must blood sugar be for glucosuria to happen

A

180

tmax of glucose transporters in kidney

20
Q

preferred 1st line for outpatient diabetes
contraindication
next up

A

METFORMIN 1st line
contraindicated in CKD (any Cr elevation)

next up GLIMEPIRIDE not contraindicated in ckd, just lower dose

21
Q

a1c goal for diabetic

A

v7… but still treat (metformin) if ^6.5

22
Q

Cr 1.5 in diabetic, 1st line glucose control drug?

A

not metformin… contraindicated in ckd (metabolic acidosis)

glimepiride - not contraindicated in ckd, just lower dose

23
Q

why isn’t simple creatinine clearance or urine dipstick for protein used to screen for diabetic nephropathy?

A

Cr actually cleared early in DM because initial hyperfiltration… low clearance only in advanced disease

dipstick can only detect ^300mg/24hr MACROalbuminuria… ^30mg/24hr is abnormal

so RANDOM MICROALBUMINURIA/CREATININE RATIO is best screening test and convenient… vs 24hr urine collection for microalbuminuria… which is actually more accurate

24
Q

type 1 diabetic on NPH bid and insulin with meals… her lunchtime sugars are high… how to adjust med regimen?

A

increase Breakfast Insulin

one meal before the high needs adjustment

25
Q

metformin’s basic moa

A

improve insulin sensitivity

26
Q

TF

Glaaaargine is Looong acting insulin

A

true

27
Q

type 1 diabetic on glaaaargine long acting qhs and prandial insulin has high breakfast sugars but normal at other meals and before bed, when checked at 3am glucose is low at 50. adjust regimen

what if 3am glucose was high?

A

Decrease qhs glaargine dose
-somogyi effect – too much insulin at night causes hypoglycemia with rebound hyperglycemia in the morning… so reduce qHS insulin

if high 3am and breakfast glucose then Dawn phenomena… liver producing glucose in sleep… so increase qHS insulin in that case

28
Q

do not modify type 1 diabetes insulin regime if sugars are below ___

A

v130 don’t touch

29
Q

Lispor is __ acting insulin

A

Lispor is rapid acting insulin - prandial

30
Q

Deeetemiiiir is a __ acting insulin

like these others

A

Deeetemiiir is a Long acting insulin
like Glaaargine
and NNNNPPPHHH

31
Q

Metformin and Glyburide depend on a funcitonal ___

A

Metformin and Glyburide depend on a funcitonal Pancreas – met enhances insulin sensitivity and glyburide pushes out more insulin from the pancreas

32
Q

ketosis and acidosis =

A

DKA

33
Q

why never intubate DKA (unless hypoxemic from another cause like pneumonia or something)

A

body can blow off more CO2 without added dead space of a ventilator

34
Q

mannitol is used to

A

mannitol used to increase intracerebral pressures

35
Q 
HHNKC/HHS
stands for
why no ketones
why hyperosmolar
why no acidosis
why coma
how treat
A

Hyperglycemic Hyperosmolar NonKetotic Coma / Hyperglycemic Hyperosmolar State

no ketones because sufficient insulin to feed the brain (t2dm not t1dm like dka)

hyperosmolar because glucose up (may suppress sodium)

no acidosis because not accessing fatty acids

coma because profound dehydration – hyperglycemia – diuresis…?

treat with Fluids and IV Insulin
Intubate FIRST if indicated by hypoxia (acidosis not a concern like DKA)
follow Symptomatic improvement (instead of AGAP in DKA)

36
Q

acid base distrubance in opiate overdose

A

hypoxemic hypercapnic respiratory alkalosis

37
Q

coma cocktail given by ems

A

naloxone (opiate overdose)
thiamine (…)
D5 (hypoglyemia)

can help for common coma causes but won’t hurt
