Endo 2 Flashcards
ADA criteria for the diagnosis of DM
4
- hgb a1c greater than or equal to 6.5 (need 2 tests elevated)
- FPG greater than or equal to 126 (need 2 tests elevated)
- 2 hour plasma glucose greater than or equal to 200 during an OGTT with 75 g glucose load
- random plasma glucose greater than or equal to 200 PLUS presence of classic symptoms of hyperglycemia crisis (need polyuria, polydipsia, or polyphagia)
which lipids are sensitive to nonfasting states and will give an abnormally elevated value if performed in a nonfasting patient
triglycerides
what tests are critical to assessing a patient’s diabetic status (besides blood sugar and a1c)
3
- BP
- fasting lipids
- microalbuminuria
when serum free T4 falls, what does TSH doe
increases as the TSH stimulates the thyroid gland to increase T4 secretion
thyroid replacement dose recommendation for someone 50-60 years old
50 mcg
metabolic processes increase after supplementation of thyroid hormone - this includes what
myocardial oxygen demand with the potential of angina and arrhythmias
older adults, especially with cardiac issues should start on what dose of thyroid hormone for hypothyroid
25 mcg
thyroid hormone can be increases by what and how often
12.5-25 increments every 4-6 weeks
the ADA recommends what nephropathy screening in all patients who have type 2 DM and how often
urinary albumin-to-creatinine ratio and an eGFR at least once a year in all patients who have type 2 DM
After starting on basal insulin what do you tell them to monitor
once insulin has been initiated, 3 days of AM fasting glucose measurements should be collected and insulin dose adjusted so that the AM fasting glucose levels are 80-130
goal AM fasting glucose levels of those with type 2 DM
80-130
ADA recommends what target BP for most patients with DM and HTN
less than 140/90
TSH is high but free T4 is normal =
subclinical hypothyroidism
replacement of T4 in subclinical hypothyroidism
T4 is not normally replaced until TSH is > 10
normal serum free thyroxine (T4) level and an elevated TSH level =
subclinical hypothyroidism
s/sx in patients who have subclinical hypothyroid with TSH < 10
it is unlikely that patients present with s/sx of hypothyroidism at this level but some many report mild symptoms
repeating TSH levels time frame and why when trying to dx
due to frequent fluctuations in serum concentrations of TSH, a repeated TSH level should be obtained after 1-3 months to confirm the dx
why do we tx for subclinical hypothyroidism when TSH >10
increases the patient’s risk for associated complications and progression to overt hypothyroidism is highly likely
pioglitazone class
TZD
pioglitazone - check what after starting
liver function studies in 2-3 months as TZDs can cause hepatotoxicity
TZDs - check what after starting and when
liver function studies in 2-3 months as TZDs can cause hepatotoxicity
check liver function studies in 2-3 months of starting this med and why
TZD - hepatotoxicity
nephropathy develops in what percent of patients with DM
20-40%
when to screen for nephropathy in type 2 DM patients
at time of diagnosis
