NU 155 Test 2 Questions with 100% Verified
Correct Answers
Age related changes in endocrine
-pituitary becomes smaller
-at 20 metabolism starts to decline
-hormones decrease with older age
-FSH, LH, ADH might increase w/ older age
-BGL rise
hormones that remain unchanged
-Cortisol
-Insulin
-Thyroid hormones
pituitary gland
Anterior: TSH, ACTH, GH, FSH, LH, prolactin
Posterior: ADH, oxytocin
Thyroid Scan
-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
,T3 T4, TSH tested & no prep necessary
High metabolism is _____, and low metabolism is _____.
hot; cold & clammy
Goiter (pathology, s/s, treatment & Dx)
-Caused by iodine deficiency or increase of TSH from lack of thyroid hormone production
-first sign is enlarged front of neck
-difficulty swallowing & breathing
-increased, normal, or decreased hormone production
-physician can order a scan that uses radioactive iodine & determines cancer
Treatment:
-if iodine type: growth of gland may be stopped
-in some cases enlargement disappears
-lack of TSH; a supplemental thyroid med is given
Dx:
-pt HX.
-physical examination
-ultrasound imaging
Thyroid gland
-major role in regulating body's rate of metabolism, growth & development
-produces thyroid hormone, triiodothyronine & calcitonin
thyroid gland: health history
, -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
-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:
t3, t4( active thyroid hormones), and calcitonin (puts tons of Ca into bones)
Hyperthyroidism: pathology & treatment
-abnormally increased synthesis & secretion of thyroid hormones
-excessive doses T4 (too much levothyroxine)
-pituitary problem
-graves disease is most common type; it's an autoimmune disorder
treatment:
-beta blocker: propranolol (inhibits sympathetic nervous system)
-thyroidectomy
-radioactive iodine capsules
Hyperthyroidism: complications
