NU155 EXAM 2 2026 TEST PREPARATION
FLASHCARDS AND SUMMARY NOTES
◉ hormones that remain unchanged. Answer: -Cortisol
-Insulin
-Thyroid hormones
◉ pituitary gland. Answer: Anterior: TSH, ACTH, GH, FSH, LH,
prolactin
Posterior: ADH, oxytocin
◉ Thyroid Scan. Answer: -tell pt to avoid iodine before test; takes 6
wks to remove from body
-used to determine size, shape, & activity of thyroid gland
-to detect hyperactive "hot" spots & Hypoactive "cold" spots
-collect 24 hr urine specimens
-pt must remain still; scan is 20 min
◉ Function tests. Answer: T3 T4, TSH tested & no prep necessary
,◉ High metabolism is _____, and low metabolism is _____.. Answer:
hot; cold & clammy
◉ Goiter: pathology. Answer: -englarged thyroid gland
-one type is caused by iodine deficiency & another is an increase of
TSH from lack of thyroid hormone production
◉ Goiter: s/s. Answer: -first sign is enlarged front of neck
-pressing against esophagus & causes difficulty swallowing
-can affect trachea & interfere w/ normal breathing
-increased, normal, or decreased hormone production
-physician can order a scan that uses radioactive iodine &
determines cancer
◉ goiter: treatment. Answer: -if iodine type of goiter is treated, the
growth of gland may be stopped
-in some cases enlargement disappears
-lack of TSH; a supplemental thyroid med is given
◉ goiter: diagnosis. Answer: -pt HX.
-physical examination
-ultrasound imaging
, ◉ Thyroid gland. Answer: -major role in regulating body's rate of
metabolism, growth & development
-produces thyroid hormone, triiodothyronine & calcitonin
◉ thyroid gland: health history. Answer: -changes level of: energy,
sleep patterns, personality, mental function & emotional state
-changes in menstrual cycles, sexual function, hydration, bowel
elimination patterns & tolerance to hot/cold
◉ thyroid gland: physical exams. Answer: -VS
-height & weight
-facial expression & characteristics as well as alertness
-inspect/palpate skin for moisture, temp, texture, hair texture
-examine eyes for expothamlamos
-observe hands for tremor
◉ Thyroid has 3 key players:. Answer: t3, t4( active thyroid
hormones), and calcitonin (puts tons of Ca into bones)
◉ Hyperthyroidism: pathology. Answer: -abnormally increased
synthesis & secretion of thyroid hormones
-excessive doses T4 (too much levothyroxine)
-pituitary problem
