What labs are used to diagnose thyroid problems?
Correct Answer: Free and total T3
Free and total T4
TSH
Anti-TPO
Hypothyroidism labs
Correct Answer: increased TSH, decreased T3 &T4
hyperthyroidism labs
Correct Answer: decreased TSH and increased T3 &T4
When to recheck labs after starting levothyroxine?
Correct Answer: 6-8 weeks or after dose change, then 12 months once stabilized
S/S hypothyroidism
Correct Answer: pale, puffy, and expressionless face, cold and dry skin, brittle hair/hair
loss, low heart rate and body temperature, lethargy, fatigue, cold intolerance, mental
,status changes, thyroid enlargement
Think "hypo low and slow"
S/S hyperthyroidism
Correct Answer: strong and rapid heart rate, dysrhythmias, angina, nervousness, insomnia,
rapid thought flow and speech, muscle weakness/atrophy, increased metabolic rate (increased
heat production, increased body temperature, heat intolerance), warm/moist skin, increased
appetite, weight loss despite increased caloric intake
think "hyper as in fast"
result of not treating hypothyroidism during pregnancy
Correct Answer: permanent neuropsychological deficits in the child. First trimester: fetus
unable to produce their own thyroid hormones. Fetal thyroid gland is fully functional in the
second trimester.
Medication to treat SYMPTOMS of hyperthyroidism
Correct Answer: beta blocker (decrease HR)
non-radioactive iodine
How to take levothyroxine with food?
Correct Answer: take on an empty stomach in the morning, 30-60 minutes before
breakfast
Supplement/drug interactions with levothyroxine
, Correct Answer: antacids, iron, calcium
Confirm diabetes diagnosis prior to treatment
Correct Answer: fasting plasma glucose greater than or equal to 126, A random
plasma glucose of greater than or equal to 200 plus symptoms of diabetes, an oral
glucose tolerance test of two hours, plasma glucose of greater than or equal to 200, or a
hemoglobin A1c, a 6.5 or higher (on two occasions)
A1c general goal
Correct Answer: <7%
Older adult A1c goal
Correct Answer: <8%
When should insulin be considered?
Correct Answer: For patients with an A1c >10%, a fasting blood glucose >300 or are
markedly symptomatic
At what interval should A1c be rechecked?
Correct Answer: 2-4 times a year (every 3 months) until A1c drops to 7% and at least
every 6 months there after
action of insulin
Correct Answer: regulation of glucose metabolism. Insulin promotes glucose and amino
acid uptake into muscle and adipose tissues, and other tissues except brain and liver. It also has
an anabolic role in stimulating glycogen, fatty acid, and protein synthesis
