Q

which contraceptive devices are contraindications in pts with breast cancer

A

  4. Fetal Tone
    - - >= 1 episode of flexion/extension of fetal limbs or spine
  5. Fetal breathing movements
    - - >= 1 breathing episode for >= 30 seconds

0 - 2 for each; max score of 10

Q

what is the mechanism of changing thyroid values in first trimester pregnancy

estrogen stimulates TBG

thyroid increases hormone production to maintain steady free T4 levels

increased beta-hCG and thyroid hormone suppress TSH secretion
(hCG has structural similarity to TSH and can directly stimulate TSH receptors)

mild hyponatremia
–hormones reset threshold to increase ADH release from pituitary

183

Q

what is dx in pt with secondary amenorrhea, negative pregnancy test, normal prolactin and normal TSH

A

functional hypothalamic amenorrhea (hypoestrogenemia)

196
Q

what does a challenge with medroxyprogesterone acetate do

A

it’s a progestin challenge test that can confirm low estrogen levels

the presence of estrogen causes proliferation the endometrium, with
sloughing after the progesterone is withdrawn
–pts with low estrogen will have little/no bleeding after progesterone withdrawal as there is no endometrial lining to shed
